    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2002
    Daniela C. Grisi
    Abstract Aim: The aim of this study was to evaluate the effectiveness of a controlled-released chlorhexidine chip (CHX) as adjunctive therapy to scaling and root planing (SRP) in the treatment of chronic periodontitis. Material and methods: Twenty patients with at least four sites with probing depth ,,5 mm and bleeding on probing were selected. This randomized single-blind study was carried out in parallel design. The control group received SRP alone, while the test group received SRP plus CHX chip. The clinical parameters, Plaque Index (PlI), Papillary Bleeding Score (PBS), Bleeding on Probing (BOP), Gingival Recession (GR), Probing Depth (PD) and Relative Attachment Level (RAL), and the microbiological parameter BANA test were recorded at baseline and after 3, 6 and 9 months. Results: Both groups presented significant improvements in all parameters analyzed over the study period. There were no statistically significant differences between the two groups for any parameter analyzed after 9 months, except for BOP, which was significantly reduced in the control group. The mean reductions on PD and RAL were 2.4 mm and 1.0 mm for the control group and 2.2 mm and 0.6 mm for the test group, respectively. Conclusion: The CHX chip did not provide any clinical or microbiological benefit beyond that achieved with conventional scaling and root planning, after a 9-month period. Zusammenfassung Wirkung eines Chlorhexidin-Chips mit kontrollierter Wirkstoff-Freisetzung auf klinische und mikrobiologische Parameter parodontaler Erkrankungen Zielsetzung: Das Ziel der vorliegenden Studie war die Evaluierung der Wirksamkeit eines Chlorhexidin-Chips mit kontrollierter Wirkstoff-Freisetzung (CHX) als Adjunktivtherapie zu Zahnsteinentfernung (Scaling) und Wurzelglätten (Root planing) bei der Behandlung einer chronischen Parodontitis. Material und Methodik: Zur Teilnahme an der Studie wurden zwanzig Patienten mit mindestens vier Stellen mit einer Sondiertiefe von ,5 mm und Blutung bei der Sondierung ausgewählt. Diese randomisierte einfach-blinde Studie wurde mit Parallelgruppenaufbau durchgeführt. Die Kontrollgruppe erhielt ausschliesslich SRP, die Testgruppe dagegen erhielt SRP plus den CHX-Chip. Zu Baseline und nach 3, 6 und 9 Monaten wurden die klinischen Parameter Plaque-Index (PlI), Papillarblutungs-Score (PBS), Blutung bei Sondierung (BOP), Gingivaretraktion (GR), Sondiertiefe (PD), Relatives Attachmentniveau (RAL) und die mikrobiologischen Parameter (BANA-Test) verzeichnet. Ergebnisse: Beide Gruppen zeigten signifikante Verbesserungen aller analysierten Parameter über den Studienzeitraum. Nach 9 Monaten konnten mit Ausnahme von BOP, was in der Kontrollgruppe eine signifikante Reduktion zeigte, keine statistisch signifikanten Unterschiede zwischen den beiden Gruppen für die untersuchten Parameter festgestellt werden. Die durchschnittlichen Reduktionen bei PD und RAL waren 2,4 mm und 1,0 mm in der Kontrollgruppe und 2,2 mm bzw. 0,6 mm in der Testgruppe. Schlussfolgerung: Nach einer 9-monatigen Behandlungszeit konnten mit dem CHX-Chip zusätzlich zu dem durch konventionelles Scaling und Wurzelglätten erzielten klinischen und mikrobiologischen Nutzen keine weiteren Vorteile erzielt werden. Résumé Influence d'une capsule de chlorhexidine à libération contrôlée sur les paramètres cliniques et microbiologiques de la maladie parodontale But: Le but de cette étude était d'évaluer l'efficacité d'une capsule de chlorhexidine (CHX) à libération contrôlée comme thérapie complémentaire au détartrage et au surfaçage radiculaire (scaling and root planing, SRP) dans le traitement de la parodontite chronique. Matériaux et méthodes: Vingt patients avec au moins quatre sites présentant une profondeur au sondage ,5 mm et un saignement au sondage ont été sélectionnés. Cette étude randomisée en simple aveugle a été conduite en parallèle. Le groupe contrôle a uniquement bénéficié de SRP, tandis que le groupe test a reçu SRP plus une capsule CHX. Les paramètres cliniques, l'indice de plaque (plaque index, PlI), l'indice de saignement papillaire (papillary bleeding score, PBS), la saignement au sondage (bleeding on probing, BOP), la récession gingivale (gingival recession, GR), la profondeur au sondage (probing depth, PD), le niveau d'attache relatif (relative attachment level, RAL) et les paramètres microbiologiques (test BANA) ont été enregistrés à la base puis après 3, 6 et 9 mois. ésultats: Les deux groupes présentaient une amélioration significative de tous les paramètres analysés au cours de la période d'étude. Entre les deux groupes, il n'y avait de différence statistiquement significative pour aucun des paramètres analysés au bout de 9 mois, sauf pour le BOP qui était considérablement réduit dans le groupe contrôle. Les baisses moyennes de PD et RAL valaient respectivement 2,4 mm et 1,0 mm pour le groupe contrôle, et 2,2 mm et 0,6 mm pour le groupe test. Conclusion: A l'issue d'une période de 9 mois, la capsule CHX n'a apporté aucun bénéfice clinique ou microbiologique supérieur à celui obtenu par détartrage et surfaçage radiculaire conventionnels.

    Health-related quality of life among adult patients with moderate and severe von Willebrand disease

    JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 7 2010
    E. M. DE WEE
    Summary.,Background:,von Willebrand Disease (VWD) is the most frequent inherited bleeding disorder. It is unknown how this disorder affects quality of life. Objectives:,This nationwide multicenter cross-sectional study determined health-related quality of life (HR-QoL) in adult patients with moderate or severe VWD, and assessed whether bleeding severity and type of VWD are associated with HR-QoL. Methods:,HR-QoL was assessed using the Short Form (SF)-36, and bleeding severity was measured using the Bleeding Score (BS). Results:,Five hundred and nine patients participated; 192 males and 317 females, median age and range 45 (16,87) and 47 (16,84) years, respectively. Compared with the general population, HR-QoL in VWD patients was lower in the vitality domain (61 vs. 66 P < 0.001 for females, 67 vs. 72 P < 0.001 for males). Patients with the most severe bleeding phenotype (highest quartile BS, BS > 17) had a lower HR-QoL in eight domains than patients with a less severe bleeding type (lowest quartile BS, BS < 7) in the univariate analysis. After adjustment for age, gender, co-morbidity and employment/educational status, a more severe bleeding phenotype was associated with lower scores on the domains of physical functioning, role limitations due to physical functioning, bodily pain, general health, social functioning and physical component summary. Conclusions:,HR-QoL is lower in VWD patients compared with the general population. HR-QoL is strongly associated with bleeding phenotype. [source]

    Variability in bleeding phenotype in Amish carriers of haemophilia B with the 31008 C,T mutation

    HAEMOPHILIA, Issue 1 2009
    A. SHARATHKUMAR
    Summary., The aim of this study was to characterize the variability of bleeding phenotype and its association with plasma factor IX coagulant activity (FIX:C) in haemophilia B carriers in a large Amish pedigree with a unifying genetic mutation, C-to-T transition at base 31008 of the factor IX gene (Xq27.1,27.2). A cross-sectional survey of haemophilia B carriers included a multiple choice questionnaire evaluating symptoms of mucocutaneous bleeding, joint bleeding and bleeding after haemostatic stress [menstruation, postpartum haemorrhage (PPH), dental extractions and invasive surgeries]. Severity of bleeding was graded as 0 to 4, 0 being no bleeding whereas 4 being severe bleeding. Association between total bleeding scores and the FIX:C was evaluated. Sixty-four haemophilia B carriers participated in this study. Median age: 18 years (range 1,70 years); median bleeding score: 1 (range 0,8). Besides PPH, isolated symptoms of bruising, epistaxis, menorrhagia and postsurgical bleeding including dental extraction were not associated with lower FIX:C. Bleeding score ,3 was associated with involvement of at least two bleeding sites and a lower mean FIX:C of 42 ± 10.3% (95% CI 36.4,47.7) while a score >3 had involvement of ,2 sites and higher mean FIX:C of 54.9 ± 21.5% (95% CI 49,61), P = 0.005. Subcutaneous haematoma formation and bleeding after haemostatic stress requiring treatment were associated with bleeding scores ,3. Phenotypic variability existed among the carriers of haemophilia B who belonged to a single pedigree carrying a single unifying mutation. The utility of bleeding scores to define bleeding phenotype precisely in haemophilia B carriers needs further evaluation. [source]

    The effect of a dentifrice and mouth rinse combination containing amine fluoride/stannous fluoride on plaque and gingivitis: a 6-month field study

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2005
    S. Paraskevas
    Abstract Aim: To examine the effect of amine fluoride/stannous fluoride (AmF/SnF2)-containing dentifrice and mouth rinse on plaque formation and gingivitis as compared with habitual oral hygiene procedures with a regular sodium fluoride (NaF) dentifrice. Material and Methods: In total, 22 general practices participated in this research project. The participants (N=281) were randomly assigned into two groups: the test group received an AmF/SnF2 dentifrice,mouth rinse combination and the control group received a NaF-containing dentifrice. The patients were requested to brush twice daily for approximately 2 min. The subjects of the test group had to rinse additionally in the evening for 30 s with 10 ml of the mouth rinse. Results: Both groups started with comparable scores of plaque, bleeding and staining. At 6 months, the plaque scores were 0.95 for the AmF/SnF2 group and 0.99 for the NaF group (decrease of 16% and 10%, respectively). Bleeding scores, although significantly different from baseline, did not show differences between the two regimes. At the end of the experimental period, the overall staining was more pronounced in the AmF/SnF2 group (41%) than the NaF group (26%). Both plaque reduction and increase in staining seemed to be correlated to the amount of mouth rinse used in the test group. Conclusion: In instruction-resistant patients recruited from dental practices, the combined use of AmF/SnF2 did not decrease gingivitis at a significant level in comparison with the regular regime of two times daily brushing with an NaF-containing dentifrice. However, the above-mentioned combination resulted in greater plaque reduction than that observed with the use of the conventional dentifrice. When used according to the manufacturer's instructions, this effect on plaque scores was more pronounced. [source]

    Modulation of clinical expression of plaque-induced gingivitis: response in aggressive periodontitis subjects

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 2 2006
    Leonardo Trombelli
    Abstract Aim: The aim of this study was to characterize the gingival inflammatory response to de novo plaque accumulation in subjects treated for aggressive periodontitis (AP). The gingival inflammatory response of the AP subjects was retrospectively compared with that of periodontally healthy individuals (PH) matched for exposure to plaque and of periodontally healthy subjects previously identified as "high responders" (HR) and "low responders" (LR). Materials and Methods: 13 AP subjects and 26 matched PH subjects participated in a 21-day experimental gingivitis trial. Plaque index (PlI), Gingival index (GI), gingival crevicular fluid volume (GCF) and angulated bleeding score (AngBS) were recorded at days 0, 7, 14 and 21. Cumulative plaque exposure (CPE), i.e. PlI over time, was also calculated. Results: GCF was significantly higher in AP compared with PH group at each observation interval (p0.001). In addition, GCF was significantly higher in AP group compared with either LR or HR groups at each observation interval (p<0.001). Conclusions: These results suggest that susceptibility to gingival inflammation in response to de novo plaque accumulation may be related to susceptibility to periodontitis. [source]

    Effectiveness of periodontal therapy on the severity of cyclosporin A-induced gingival overgrowth

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2005
    Mario Aimetti
    Abstract Aim: The purpose of the present study was to evaluate the clinical effects of aetiological periodontal treatment in a group of transplant patients medicated with cyclosporin A (CsA) who exhibited severe gingival overgrowth. Materials and Methods: Twenty-one patients received oral hygiene instructions, supra- and subgingival scaling and periodontal maintenance therapy and were monitored for 12 months. Full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), periodontal probing depth and degree of gingival overgrowth (Seymour index GO) were recorded at baseline, 6 and 12 months after treatment. Results: Statistical evaluation revealed that all clinical variables significantly decreased compared with baseline. At baseline 18 out of 21 treated patients (85.71%) exhibited clinically significant overgrowth. Initial GO score of 2.38±1.92 in the anterior sextants and of 1.29±1.59 in the posterior segments were reduced to 0.56±0.83 and to 0.45±0.84 at 12 months (p<0.001). A difference of 1.82 and 0.84 in the severity of treated GO was accompained by a 42% and 34% decrease in FMPS and FMBS, respectively. Conclusions: Aetiological periodontal treatment and regular maintenance therapy were effective in resolving the inflammation and in eliminating the need for surgical treatment in patients receiving CsA.

    Comparison of infrabony defects treated with enamel matrix derivative versus guided tissue regeneration with a nonresorbable membrane

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 5 2003
    A multicenter controlled clinical trial
    Abstract Aim: The purpose of the present multicenter clinical trial was to compare the efficacy of two different procedures in the treatment of infrabony defects: guided tissue regeneration (GTR) with nonresorbable membranes and enamel matrix derivative (EMD). Material and methods: Six centers participated in this study. Ninety-eight patients with an interproximal infrabony defect were selected. All patients were treated with an initial phase of scaling and root planing, and at the study's baseline the selected defects presented a value of probing depth (PD) ,6 mm with an infrabony component ,4 mm. Forty-nine patients were treated with GTR procedures (using ePTFE membranes (Gore-Tex W.L. Gore and Associates, Flagstaff, AZ, USA)) and forty-nine with EMDs (Emdogain® (Û Biora AB Malm, Sweden)). The efficacy of each treatment modality was investigated through covariance analysis. Results: The patients were reevaluated at one year postop. Probing attachment level (PAL) gain and PD reduction were analyzed. In the Emdogain® group the PAL before surgery (PAL 0) and the PD before surgery (PD 0) were respectively 9.9±1.4 and 8.5±1.6 mm. The PAL gain and the PD reduction at 1 year postsurgery were respectively 4.1±1.8 and 5.3±1.9 mm. The group of patients treated with membranes showed that PAL 0 and PD 0 were respectively 8.9±1.9 and 8.1±1.9. The PAL gain was 4.3±1.9 mm and the PD reduction was 5.6±1.5 mm. The mean PAL gain expressed by percentage (PAL gain/PAL 0) for the group treated with EMD was 41%, while it was 48% for the group treated with GTR. Results from our analysis suggest that there is no statistically significant difference between GTR and EMD treatments in terms of PAL gain, PD reduction and recession variation. Applying the regression model to a group of patients with a PAL 0 ,8 mm, we observed a better clinical outcome in terms of PAL gain (difference of 0.3 mm) in patients treated with the GTR procedure compared to those treated with EMD. Covariance analysis showed a strong correlation in both groups of patients between PAL gain and full mouth bleeding score, and between PAL gain and defect morphology and depth. Zusammenfassung Ziel: Der Zweck der vorliegenden klinischen Multicenterstudie war der Vergleich der Effektivität von zwei unterschiedlichen Prozeduren in der Behandlung von intraalveolären Defekten: gesteuerte Geweberegeneration (GTR) mit nicht resorbierbaren Membranen und Schmelz-Matrix-Derivaten (EMD). Material und Methoden: Sechs Zentren nahmen an der Studie teil. 98 Patienten mit approximalen intraalveolären Defekten wurden ausgesucht. Alle Patienten wurden in der initialen Phase mit Wurzelreinigung und ,glättung behandelt, und zur Basis der Studie zeigten die ausgewählten Defekte Sondierungstiefen von 6 mm mit einem intraalveolären Anteil von 4 mm. 49 Patienten wurden mit dem GTR Verfahren (unter Nutzung einer e-PTFE Membran1) und 49 Patienten mit den Schmelz-Matrix-Derivaten (Emdogain®2) behandelt. Die Effektivität von jeder Behandlungsvariante wurde mit der Kovarianzanalyse untersucht. Ergebnisse: Die Patienten wurden 1 Jahr nach der Operation reevaluiert. Die Veränderungen des Stützgewebeniveaus (PAL) und die Reduktion der Sondierungstiefen (PD) wurden analysiert. In der Emdogain® Gruppe betrugen die PAL (PAL 0) und die PD (PD 0) vor der Chirurgie 9,9±1,4 mm und 8,5±1,6 mm. Der PAL Gewinn und die PD Verringerung nach einem Jahr postoperativ waren 4,1±1,8 mm und 5,3±1,9 mm. Die Gruppe der Patienten, die mit Membranen behandelt worden waren, zeigten Werte von PAL 0 und PD 0 von 8,9±1,9 mm und 8,1±1,9 mm. Der PAL Gewinn betrug 4,3±1,9 mm und die PD Reduktion 5,6±1,5 mm. Der mittlere PAL Gewinn in Prozent (PAL Gewinn/PAL 0) für die EMD-Gruppe war 41%, während er für die GTR-Gruppe 48 % betrug. Die Ergebnisse unserer Analyse zeigen, dass keine statistisch signifikante Differenz zischen GTR und EMD Behandlungen in Bezug auf PAL Gewinn, PD Reduktion und REC Veränderung bestand. Unter Nutzung der Regressionsanalyse für eine Gruppe mit PAL 0 ,8 mm beobachteten wir ein besseres klinisches Ergebnis bezüglich des PAL Gewinns (Differenz 0,3 mm) bei GTR-Patienten verglichen mit EMD-Patienten. Die Kovarianzanalyse zeigte eine starke Korrelation in beiden Patientengruppen zwischen PAL Gewinn und dem vollständigen Blutungsindex (FMBS) sowie zwischen PAL Gewinn und Morphologie und Tiefe des Defektes. Résumé Le but de cet essai clinique multicentrique a été de comparer l'efficacité de deux processus différents dans le traitement des lésions intraosseuses : la régénération tissulaire guidée (GTR) avec des membranes non-résorbables et les dérivés de la matrice amélaire (EMD). Six centres ont participéà cette étude. Nonante-huit patients avec une lésion intraosseuse interproximale ont été sélectionnés. Tous ont été traités par une phase initiale de détartrage et surfaçage, et au début de l'étude les lésons sélectionnées avaient une profondeur de poche de 6 mm (PD) avec un composant infraosseux ,4 mm. Quarante-neuf patients ont été traités par GTR en utilisant une membrane en téflon et 49 par EMD (Emdogain®2). L'efficacité de chaque traitement a étéétudiée par l'analyse de co-variance. Les patients ont été réévalués un an après l'opération. Le gain du niveau d'attache au sondage (PAL) et la réduction de PD ont été analysés. Dans le groupe EMD, le PAL et le PD présents avant la chirurgie, (PAL 0) et (PD 0), étaient respectivement de 9,9±1,4 mm et de 8,5±1,6 mm. Le gain PAL et la réduction de PD après une année étaient respectivement de 4,1±1,8 mm et 5,3±1,9 mm. Le groupe de patients traités avec les membranes accusaient un PAL 0 et un PD 0 qui étaient respectivement de 8,9±1,9 mm et de 8,1±1,9 mm. Le gain PAL était de 4,3±1,9 mm après une année tandis que la réduction PD était de 5,6±1,5 mm. Le gain PAL moyen exprimé en pourcentage (gain PAL/PAL 0) pour le groupe traité avec EMD était de 41% tandis qu'il était de 48 % dans le groupe traité par GTR. Les résultats de cette analyse suggèrent qu'il n'y a aucune différence statistique entre les traitements GTR et EMD en terme de gain PAL, de réduction PD et dans le changement de récession. Lors de l'utilisation du modèle de régression sur un groupe de patients avec un PAL 0 ,8 mm, une guérison clinique supérieure était observée dans le gain PAL (différence de 0,3 mm) chez les patients traités avec GTR comparés à ceux traités par EMD. L'analyse de co-variance montrait une relation importante dans les deux groupes de patients entre le gain PAL et le score de saignement de l'ensemble de la bouche, et entre le gain PAL et la morphologie de la lésion et sa profondeur.

    Impaired healing response of periodontal furcation defects following flap debridement surgery in smokers

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2003
    A controlled clinical trial
    Abstract Objectives: The purpose of the present parallel-design, controlled clinical trial was to evaluate the treatment outcome of periodontal furcation defects following flap debridement surgery (FDS) procedure in cigarette smokers compared to non-smokers. Materials and Methods: After initial therapy, 31 systemically healthy subjects with moderate to advanced periodontitis, who presented at least one Class I or II molar furcation defect, were selected. Nineteen patients (mean age: 40.3 years, 15 males) were smokers (,10 cigarettes/day) and 12 patients (mean age: 44.8 years, 3 males) were non-smokers. Full-mouth plaque score (FMPS) and full-mouth bleeding score (FMBS), probing pocket depth (PPD), vertical clinical attachment level (v-CAL), and horizontal clinical attachment level (h-CAL) were assessed immediately before and 6 months following surgery. Results: Overall, statistically significant v-CAL gain was observed in smokers (1.0 ± 1.3 mm) and non-smokers (1.3±1.1 mm), the difference between groups being statistically significant (p=0.0003). In proximal furcation defects, v-CAL gain amounted to 2.3±0.7 mm in non-smokers as compared to 1.0±1.1 mm in smokers (p=0.0013). At 6 months postsurgery, non-smokers presented a greater h-CAL gain (1.3±1.1 mm) than smokers (0.6±1.0 mm), with a statistically significant difference between groups (p=0.0089). This trend was confirmed in both facial/lingual (1.4±1.0 versus 0.8±0.8 mm) and proximal furcation defects (1.2±1.3 versus 0.5±1.2 mm). The proportion of Class II furcations showing improvement to postsurgery Class I was 27.6% in smokers and 38.5% in non-smokers. After 6 months, 3.4% of presurgery Class I furcation defects in smokers showed complete closure, as compared to 27.8% in non-smokers. Conclusions: The results of the present study indicated that (1) FDS produced clinically and statistically significant PPD reduction, v-CAL gain, and h-CAL gain in Class I/II molar furcation defects, and (2) cigarette smokers exhibited a less favorable healing outcome following surgery in terms of both v-CAL and h-CAL gain. Zusammenfassung Ziele: Der Zweck der vorliegenden kontrollierten klinischen Studie mit einem parallelen Design war die Überprüfung des Behandlungsergebnisses bei parodontalen Furkationsdefekten nach Wurzelreinigung und ,glättung bei Lappenoperationen (FDS) bei Zigarettenrauchern und Nichtrauchern. Material und Methoden: Nach der initialen Therapie wurden 31 systemisch gesunde Personen mit moderater bis schwerer Parodontitis, die mindestens einen Klasse I oder Klasse II Furkationsdefekt aufwiesen, ausgesucht. 19 Patienten (mittleres Alter 40,3 Jahre, 15 Männer) waren Raucher (,10 Zigaretten/Tag), 12 Patienten (mittleres Alter 44,8 Jahre, 3 Männer) waren Nichtraucher. Der Plaqueindex (FMPS) und die Provokationsblutung (FMBS) im gesamten Mund, die Sondierungstiefen (PPD), die vertikalen klinischen Befestigungsniveaus (v-CAL) und die horizontalen klinischen Befestigungsniveaus (h-CAL) wurden unmittelbar vor und 6 Monate nach der Operation erhoben. Ergebnisse: Insgesamt wurde ein statistisch signifikanter v-CAL Gewinn bei Rauchern (1,0±1,3 mm) und Nichtrauchern (1,3±1,1 mm) beobachtet, die Differenz wischen den Gruppen war statistisch signifikant (p=0,0003). Bei den approximalen Furkationsdefekten betrug der v-CAL Gewinn bei Nichtrauchern 2,3±0,7 mm verglichen zu den Rauchern mit 1,0±1,1 mm (p=0,0013). 6 Monate post operationem zeigten die Nichtraucher einen größeren h-CAL Gewinn (1,3±1,1 mm) verglichen mit den Rauchern (0,6±1,0 mm) mit einer statistischen Signifikanz zwischen den Gruppen (p=0,0089). Dieser Trend wurde sowohl bei den fazialen/lingualen Defekten (1,4±1,0 mm vs. 0,8±0,8 mm) und bei den approximalen Furkationsdefekten (1,2 v 1,3 mm vs. 0,5±1,2 mm) bestätigt. Das Verhältnis von Klasse II Furkationen, die post operationem eine Verbesserung zu Klasse I Furkationsdefekten zeigten, war bei Rauchern 27,6 % und 38,5 % bei Nichtrauchern. Nach 6 Monaten zeigten 3,4 % der Klasse I Furkationsdefekte bei Rauchern einen kompletten Verschluss verglichen mit 27,8 % bei Nichtrauchern. Zusammenfassung: Die Ergebnisse der vorliegenden Studie zeigten, dass 1) FDS eine klinische und statistisch signifikante PPD Reduktion, einen v-CAL Gewinn und h-CAL Gewinn bei Klasse I/II Molaren Furkationsdefekten erbringt; 2) Zigarettenraucher weniger gute Heilungsergebnisse nach Operationen sowohl bei v-CAL als auch bei h-CAL zeigten. Résumé Objectifs: cette étude clinique contrôlée en parallèle se proposait d'évaluer l'issue du trai-tement des lésions des furcations par un lam-beau de débridement (FDS) chez des fumeurs de cigarette par rapport à des non-fumeurs. Matériel et méthodes: Après un traitement initial, 31 sujets en bonne santé atteints de parodontite modérée à avancée et présentant au moins une lésion inter-radiculaire de classe I ou II sur une molaire, furent sélectionnés. 19 patients (d'âge moyen: 40.3 ans, 15 hommes) étaient fumeurs (,10 cigarettes/jour), 12 patients (d'âge moyen: 44.8 ans, 3 hommes) étaient non-fumeurs. Le score de plaque de toute la bouche (FMPS) et le score de saignement (FMBS), la profondeur de poche au sondage (PPD), le niveau clinique d'attache vertical (v-CAL), et horizontal (h-CAL) furent estimés immédiatement avant et 6 mois après la chirurgie. Résultats: D'une façon générale, un gain de v-CAL statistiquement significatif gain était observé chez les fumeurs (1.0±1.3 mm) et chez les non-fumeurs (1.3±1.1 mm), la différence entre les groupes étant statistiquement significative (p=0.0003). Pour les lésions des furcations proximales, le gain de v-CAL atteignait 2.3±0.7 mm chez les non-fumeurs et seulement 1.0±1.1 mm chez les fumeurs (p=0.0013). 6 mois après la chirurgie, les non-fumeurs présentaient un gain de h-CAL gain plus important (1.3±1.1 mm) que les fumeurs(0.6±1.0 mm), avec une différence statistiquement significative entre les groupes (p=0.0089). Cette tendance était confirmée à la fois sur les lésions des furcations vestibulo-linguales (1.4±1.0 mm vs 0.8±0.8 mm) et proximales (1.2±1.3 mm vs 0.5±1.2 mm). La proportion de furcations de Classe II s'améliorant après chirurgie en Classe I était de 27.6% chez les fumeurs et 38.5% chez les non-fumeurs. Après 6 mois, 3.4% des furcations initialement de Classe I étaient complètement fermées contre 27.8% chez les non-fumeurs. Conclusions: Les résultats de cette étude indiquent que: 1) FDS produit une réduction cliniquement et statistiquement significative de PPD, un gain de v-CAL et de h-CAL gain sur les lésions de furcations molaires de Classe I/II; 2) Les fumeurs de cigarette ont une cicatrisation moins favorable après chirurgie en terme de gain de v-CAL et de h-CAL.

    Effect of a controlled-release chlorhexidine chip on clinical and microbiological parameters of periodontal syndrome

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2002
    Daniela C. Grisi
    Abstract Aim: The aim of this study was to evaluate the effectiveness of a controlled-released chlorhexidine chip (CHX) as adjunctive therapy to scaling and root planing (SRP) in the treatment of chronic periodontitis. Material and methods: Twenty patients with at least four sites with probing depth ,,5 mm and bleeding on probing were selected. This randomized single-blind study was carried out in parallel design. The control group received SRP alone, while the test group received SRP plus CHX chip. The clinical parameters, Plaque Index (PlI), Papillary Bleeding Score (PBS), Bleeding on Probing (BOP), Gingival Recession (GR), Probing Depth (PD) and Relative Attachment Level (RAL), and the microbiological parameter BANA test were recorded at baseline and after 3, 6 and 9 months. Results: Both groups presented significant improvements in all parameters analyzed over the study period. There were no statistically significant differences between the two groups for any parameter analyzed after 9 months, except for BOP, which was significantly reduced in the control group. The mean reductions on PD and RAL were 2.4 mm and 1.0 mm for the control group and 2.2 mm and 0.6 mm for the test group, respectively. Conclusion: The CHX chip did not provide any clinical or microbiological benefit beyond that achieved with conventional scaling and root planning, after a 9-month period. Zusammenfassung Wirkung eines Chlorhexidin-Chips mit kontrollierter Wirkstoff-Freisetzung auf klinische und mikrobiologische Parameter parodontaler Erkrankungen Zielsetzung: Das Ziel der vorliegenden Studie war die Evaluierung der Wirksamkeit eines Chlorhexidin-Chips mit kontrollierter Wirkstoff-Freisetzung (CHX) als Adjunktivtherapie zu Zahnsteinentfernung (Scaling) und Wurzelglätten (Root planing) bei der Behandlung einer chronischen Parodontitis. Material und Methodik: Zur Teilnahme an der Studie wurden zwanzig Patienten mit mindestens vier Stellen mit einer Sondiertiefe von ,5 mm und Blutung bei der Sondierung ausgewählt. Diese randomisierte einfach-blinde Studie wurde mit Parallelgruppenaufbau durchgeführt. Die Kontrollgruppe erhielt ausschliesslich SRP, die Testgruppe dagegen erhielt SRP plus den CHX-Chip. Zu Baseline und nach 3, 6 und 9 Monaten wurden die klinischen Parameter Plaque-Index (PlI), Papillarblutungs-Score (PBS), Blutung bei Sondierung (BOP), Gingivaretraktion (GR), Sondiertiefe (PD), Relatives Attachmentniveau (RAL) und die mikrobiologischen Parameter (BANA-Test) verzeichnet. Ergebnisse: Beide Gruppen zeigten signifikante Verbesserungen aller analysierten Parameter über den Studienzeitraum. Nach 9 Monaten konnten mit Ausnahme von BOP, was in der Kontrollgruppe eine signifikante Reduktion zeigte, keine statistisch signifikanten Unterschiede zwischen den beiden Gruppen für die untersuchten Parameter festgestellt werden. Die durchschnittlichen Reduktionen bei PD und RAL waren 2,4 mm und 1,0 mm in der Kontrollgruppe und 2,2 mm bzw. 0,6 mm in der Testgruppe. Schlussfolgerung: Nach einer 9-monatigen Behandlungszeit konnten mit dem CHX-Chip zusätzlich zu dem durch konventionelles Scaling und Wurzelglätten erzielten klinischen und mikrobiologischen Nutzen keine weiteren Vorteile erzielt werden. Résumé Influence d'une capsule de chlorhexidine à libération contrôlée sur les paramètres cliniques et microbiologiques de la maladie parodontale But: Le but de cette étude était d'évaluer l'efficacité d'une capsule de chlorhexidine (CHX) à libération contrôlée comme thérapie complémentaire au détartrage et au surfaçage radiculaire (scaling and root planing, SRP) dans le traitement de la parodontite chronique. Matériaux et méthodes: Vingt patients avec au moins quatre sites présentant une profondeur au sondage ,5 mm et un saignement au sondage ont été sélectionnés. Cette étude randomisée en simple aveugle a été conduite en parallèle. Le groupe contrôle a uniquement bénéficié de SRP, tandis que le groupe test a reçu SRP plus une capsule CHX. Les paramètres cliniques, l'indice de plaque (plaque index, PlI), l'indice de saignement papillaire (papillary bleeding score, PBS), la saignement au sondage (bleeding on probing, BOP), la récession gingivale (gingival recession, GR), la profondeur au sondage (probing depth, PD), le niveau d'attache relatif (relative attachment level, RAL) et les paramètres microbiologiques (test BANA) ont été enregistrés à la base puis après 3, 6 et 9 mois. ésultats: Les deux groupes présentaient une amélioration significative de tous les paramètres analysés au cours de la période d'étude. Entre les deux groupes, il n'y avait de différence statistiquement significative pour aucun des paramètres analysés au bout de 9 mois, sauf pour le BOP qui était considérablement réduit dans le groupe contrôle. Les baisses moyennes de PD et RAL valaient respectivement 2,4 mm et 1,0 mm pour le groupe contrôle, et 2,2 mm et 0,6 mm pour le groupe test. Conclusion: A l'issue d'une période de 9 mois, la capsule CHX n'a apporté aucun bénéfice clinique ou microbiologique supérieur à celui obtenu par détartrage et surfaçage radiculaire conventionnels.

    Comparison of the bleeding on marginal probing index and the Eastman interdental bleeding index as indicators of gingivitis

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 3 2002
    D. S. Barendregt
    Abstract Aim: The purpose of the present study was to compare 2 indices, i.e., the Eastman interdental bleeding (EIB) index and the bleeding on marginal probing (BOMP) index. The comparison was made (a) in terms of the degree of bleeding provoked and the relationship with plaque in natural gingivitis and (b) for the ability of these 2 methods to detect differences between the development of experimental gingivitis in a control group and a group in which the development of gingival inflammation was suppressed by treatment. For the present studies, subjects were selected without interdental recession of the gingival tissues. Methods experiment 1: In this experiment, 43 subjects having established moderate gingivitis were assessed using a random splitmouth design (1st and 3rd/2nd and 4th quadrant). Plaque was scored on all approximal sites after which the BOMP index was assessed in one half of the mouth and the EIB index in the other. Results experiment 1: The BOMP index showed a bleeding score of 84% and the EIB index of 87%. The significant correlation between plaque and gingival bleeding for the BOMP index (0.55) was higher than for the EIB index (0.44). Methods experiment 2: For this experiment, 25 subjects participated in an experimental gingivitis trial of the lower jaw. At baseline, first the BOMP index and immediately thereafter the EIB index were assessed at all approximal sites. Experimental gingivitis (EG) was carried out in one randomly assigned quadrant and as a treatment modality only floss was used in the other (FL). Results experiment 2: In the EG quadrant, the BOMP index increased to 69% and the EIB index to 73%. Both indices showed a significant correlation with plaque; 0.60 and 0.64 respectively. In the FL quadrant, the BOMP index increased to 38% and the EIB index to 30%. No significant correlation between both gingivitis indices and the amount of plaque was present in the FL quadrant. Conclusion: The ability of the BOMP index and the EIB index to assess the level gingival inflammation appears to be comparable. Zusammenfassung Ziel: Der Zweck der vorliegenden Studie war es, die 2 Indizes, den Eastman Interdental Bleeding (EIB) Index und den Bleeding On Marginal Probing (BOMB) Index zu vergleichen. Der Vergleich erfolgte. (A) hinsichtlich des provozierten Blutungsgrades und der Relation zwischen Plaque und natürlicher Gingivitis sowie: (B) bezüglich der Fähigkeit dieser 2 Methoden hinsichtlich des Nachweises von Unterschieden zwischen der Entwicklung einer experimentellen Gingivitis in einer Kontrollgruppe und einer Gruppe in der die Ausbildung einer gingivalen Entzündung durch die Behandlung unterdrückt wurde. Für die vorliegende Studie wurden Personen ohne interdentale Gingivarezession ausgewählt. Methoden Experiment 1: Bei diesem Experiment wurden 43 Personen mit etablierter moderater Gingivitis nach einem randomisierten Splitmouth-Design untersucht (1. Und 3./2. Und 4. Quadrant). Die Plaque wurde an allen approximalen Flächen bestimmt und anschließend wurde BOMP-Index in der einen Hälfte des Gebisses und der EIB-Index in der anderen erhoben. Ergebnisse Experiment 1: Der BOMP-Index zeigte einen Blutungswert von 84% und der EIB-Index einen von 87%. Die signifikante Korrelation zwischen der Plaque und einer gingivalen Blutung war für den BOMP-Index (0.55) höher als für den EIB-Index (0.44). Methoden Experiment 2: Für diese Experiment wurde bei 25 Personen eine experimentelle Gingivitis im Unterkiefer erzeugt. Bei der Eingangsuntersuchung wurde an allen Approximalflächen zuerst der BOMP-Index und sofort anschließend der EIB-Index erhoben. Die experimentelle Gingivitis (EG) wurde in einem randomisiert bestimmten Quadranten erzeugt und als Behandlungsart wurde im anderen Quadranten nur Zahnseide (FL) verwendet. Ergebnisse Experiment 2: Im EG-Quadranten stiegen der BOMP-Index auf 69% und der EIB-Index auf 73% an. Beide Indizes zeigten eine signifikante Korrelation mit der Plaque, die bei 0.60 bzw. 0.64 lag. Im FL-Quadranten stiegen der BOMP-Index auf 38% und der EIB-Index auf 30% an. Zwischen beiden Gingivitis-Indizes und der Plaquemenge, die im FL-Quadranten vorhanden war, gab es keine signifikante Korrelation. Schlussfolgerung: Die Möglichkeit mit dem BOMP-Index und den EIB-Index das Niveau der gingivalen Entzündung zu Bestimmen scheint vergleichbar zu sein. Résumé But: Le but de cette étude a été de comparer 2 indices, c-à-d. l'indice du saignement interdentaire d'Eastman (EIB) et l'indice du saignement au sondage marginal (BOMP). La comparaison a été effectuée (a) en termes de saignement provoqué et de relation avec la plaque dentaire dans la gingivite naturelle et (b) sur l'aptitude de ces 2 méthodes à détecter des différences lors du dévelopment d'une gingivite expérimentale dans un groupe contrôle et dans un groupe test dont le dévelopement de l'inflammation gingivale a été entravé par un traitement. Pour ces études, des sujets qui ne présentaient pas de récession interdentaire ont été sélectionnés. Méthodes, expérience 1: Dans la première expérimentation, 43 sujets étant porteurs d'une gingivite modérée ont été enregistrés en utilisant un modèle de bouche divisée au hasard (1er et 3ième quadrants VS 2ième et 4ième quadrants). La plaque dentaire a été estimée sur tous les sites interproximaux. Résultats expérience 1: L'indice BOMP a ensuite été relevé sur une partie de la bouche et l'indice EIB sur l'autre. L'indice BOMP a eu un score de 84% et l'EIB de 87%. La corrélation significative entre la présence de plaque dentaire et le saignement gingival était pour l'indice BOMP de 0.55, supérieur donc à celui de l'EIB qui était de 0.44. Méthodes expérience 2: Lors de la seconde expérience, 25 sujets ont participéà une gingivite expérimentale au niveau de la mandibule. Lors de l'examen de départ l'indice BOMP a été relevé en premier suivi de celui de l'EIB au niveau de tous les sites interproximaux. La gingivite expérimentale (EG) a été effectuée sur un quadrant choisi de manière randomisée et un traitement avec de la soie dentaire uniquement a été utilisé dans l'autre (FL). Résultats expérience 2: Dans le quadrant avec EG l'indice BOMP atteignait 69% et l'indice EIB à 73%. Les deux indices avaient une corrélation significative avec la plaque dentaire, respectivement de 0.60 et 0.64. Dans le quadrant FL, l'indice BOMP grimpait à 38% et l'indice EIB à 30%. Aucune corrélation significative entre les deux indices de gingivite et la quantité de plaque n'a été trouvé dans le quadrant FL. Conclusions: L'aptitude des indices BOMP et EIB à mesurer le niveau d'inflammation gingivale semble comparable. [source]

    Efficacy and safety of secondary prophylactic vs. on-demand sucrose-formulated recombinant factor VIII treatment in adults with severe hemophilia A: results from a 13-month crossover study

    JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 1 2010
    P. COLLINS
    Summary.,Background: Hemarthroses in severe hemophilia precipitate physical, psychosocial and financial difficulties. Objective: To compare the effects of secondary prophylaxis with on-demand sucrose-formulated recombinant factor VIII (rFVIII-FS) therapy in severe hemophilia A. Patients and methods: This open-label study included patients aged 30,45 years with factor VIII (FVIII) coagulant activity < 1 IU dL,1 who were using on-demand FVIII treatment. Patients were treated with rFVIII-FS on demand for 6 months, followed by 7 months prophylaxis (20,40 IU kg,1, three times per week, with the first month considered a run-in). The primary endpoint was the number of hemarthroses. Results: Twenty patients were enrolled (n = 19 completed); the mean age was 36.4 years, and 16 had target joints. The median (25,75%) number of joint bleeds decreased significantly with prophylaxis [0 (0,3)] vs. on-demand [15 (11,26); P < 0.001] therapy. The number of all bleeds was 0 (0,3) vs. 20.5 (14,37; P < 0.001), respectively. Median (range) total Gilbert scores improved after prophylaxis [18 (3,39)] compared with on-demand [25 (4,46)] therapy, predominantly reflecting the improved bleeding score. Median time from last prophylactic infusion to bleed was 2 days; 82.5% of bleeds occurred 2,3 days after the last infusion. Median 48-h and 72-h FVIII trough levels measured during months 10 and 13 were consistently > 6 and > 4 IU dL,1, respectively. Treatment was well tolerated, and no inhibitor formation was observed. Conclusion: Secondary prophylaxis with rFVIII-FS significantly reduced the frequency of hemarthroses compared with on-demand therapy in adult patients with severe hemophilia A. [source]

    Generation and validation of the Condensed MCMDM-1VWD Bleeding Questionnaire for von Willebrand disease

    JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 12 2008
    M. BOWMAN
    Summary.,Background:,Given the challenges involved in obtaining accurate bleeding histories, attempts at standardization have occurred and the value of quantifying hemorrhagic symptoms has been recognized. Patients/methods:,An extensive validated bleeding questionnaire (MCMDM-1VWD) was condensed by eliminating all details that did not directly affect the bleeding score (BS) and the correlation between the two versions was tested. Additionally, the diagnostic utility of the condensed version was prospectively tested. Results:,Data on 259 individuals who were administered the questionnaire are presented here; 217 being prospectively investigated for von Willebrand disease (VWD) (group 1) and 42 previously known to have type 1, 2 or 3 VWD (group 2). Of the 217 prospectively investigated, 35 had positive BS (,4) and 182 had negative scores. Seven individuals (all with positive BS) had laboratory results consistent with type 1 VWD. This results in a sensitivity of 100% and a specificity of 87%. The positive predictive value is 0.20 and the negative predictive value is 1. The correlation between the full MCMDM-1VWD and condensed versions is excellent (Spearman's 0.97, P < 0.001, linear regression r2 = 96.4). Inter-observer reliability for the condensed version is reasonable (Spearman's 0.72, P < 0.001 and intra-class correlation coefficient 0.805, P < 0.001). There was a significant difference in BS between subtypes of VWD, with type 3 >> type 2 >> type 1 VWD (anovaP < 0.001). There is a strong inverse relationship between VWF:Ag level and BS (Spearman's ,0.411, P < 0.001). Conclusions:,The Condensed MCMDM-1VWD Bleeding Questionnaire is an efficient, effective tool in the evaluation of patients for VWD. [source]

    Variability in bleeding phenotype in Amish carriers of haemophilia B with the 31008 C,T mutation

    HAEMOPHILIA, Issue 1 2009
    A. SHARATHKUMAR
    Summary., The aim of this study was to characterize the variability of bleeding phenotype and its association with plasma factor IX coagulant activity (FIX:C) in haemophilia B carriers in a large Amish pedigree with a unifying genetic mutation, C-to-T transition at base 31008 of the factor IX gene (Xq27.1,27.2). A cross-sectional survey of haemophilia B carriers included a multiple choice questionnaire evaluating symptoms of mucocutaneous bleeding, joint bleeding and bleeding after haemostatic stress [menstruation, postpartum haemorrhage (PPH), dental extractions and invasive surgeries]. Severity of bleeding was graded as 0 to 4, 0 being no bleeding whereas 4 being severe bleeding. Association between total bleeding scores and the FIX:C was evaluated. Sixty-four haemophilia B carriers participated in this study. Median age: 18 years (range 1,70 years); median bleeding score: 1 (range 0,8). Besides PPH, isolated symptoms of bruising, epistaxis, menorrhagia and postsurgical bleeding including dental extraction were not associated with lower FIX:C. Bleeding score ,3 was associated with involvement of at least two bleeding sites and a lower mean FIX:C of 42 ± 10.3% (95% CI 36.4,47.7) while a score >3 had involvement of ,2 sites and higher mean FIX:C of 54.9 ± 21.5% (95% CI 49,61), P = 0.005. Subcutaneous haematoma formation and bleeding after haemostatic stress requiring treatment were associated with bleeding scores ,3. Phenotypic variability existed among the carriers of haemophilia B who belonged to a single pedigree carrying a single unifying mutation. The utility of bleeding scores to define bleeding phenotype precisely in haemophilia B carriers needs further evaluation. [source]

    Dental hygiene education for nursing staff in a nursing home for older people

    kullberg e., sjögren p., forsell m., hoogstraate j., herbst b. & johansson o. (2010) Dental hygiene education for nursing staff in a nursing home for older people. Journal of Advanced Nursing,66(6), 1273,1279. Abstract Title.,Dental hygiene education for nursing staff in a nursing home for older people. Aim., This paper is a report of a study evaluating the effect of a repeated education programme for nursing staff in a home for older people. Background., A strong relationship exists between oral infections and general health complications (especially aspiration pneumonia) among nursing home residents and hospitalized older people. Thus, nursing staff need to be educated in oral hygiene measures. Methods., Forty-three nursing home resident older people (12 men, 31 women, age range 69,99 years) were included in a dental hygiene and gingivitis evaluation using gingival bleeding scores and modified plaque scores. Evaluation was conducted before and 3 weeks after a repeated dental hygiene education for nursing staff at a nursing home in Sweden in 2008. Dental hygiene education had been given 1·5 years previously. Findings., Forty-one residents (12 men and 29 women) were available for evaluation after the repeated dental hygiene education (one died, one had had teeth extracted). There was a reduction in gingival bleeding scores (P < 0·001), and in plaque scores (P < 0·001). Conclusion., Repeated dental hygiene education improves the dental hygiene among nursing home resident older people. In order to succeed it may be necessary to address attitudes and perceptions towards oral care in such a dental hygiene education programme for nursing staff. Improved oral hygiene contributes to reducing the incidence of healthcare-associated pneumonia among nursing home resident older people, and thus to reduced healthcare costs. [source]

    Mechanical non-surgical treatment of peri-implantitis: a double-blind randomized longitudinal clinical study.

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2009
    I: clinical results
    Abstract Background: Peri-implantitis is a frequent finding in patients with dental implants. The present study compared two non-surgical mechanical debridement methods of peri-implantitis. Material and Methods: Thirty-seven subjects (mean age 61.5; S.D±12.4), with one implant each, demonstrating peri-implantitis were randomized, and those treated either with titanium hand-instruments or with an ultrasonic device were enrolled. Data were obtained before treatment, and at 1, 3, and 6 months. Parametric and non-parametric statistics were used. Results: Thirty-one subjects completed the study. The mean bone loss at implants in both groups was 1.5 mm (SD ±1.2 mm). No group differences for plaque or gingival indices were found at any time point. Baseline and 6-month mean probing pocket depths (PPD) at implants were 5.1 and 4.9 mm (p=0.30) in both groups. Plaque scores at treated implants decreased from 73% to 53% (p<0.01). Bleeding scores also decreased (p<0.01), with no group differences. No differences in the total bacterial counts were found over time. Higher total bacterial counts were found immediately after treatment (p<0.01) and at 1 week for ultrasonic-treated implants (p<0.05). Conclusions: No group differences were found in the treatment outcomes. While plaque and bleeding scores improved, no effects on PPD were identified. [source]

    Microbial colonization patterns predict the outcomes of surgical treatment of intrabony defects

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2006
    Lisa Heitz-Mayfield
    Abstract Aim: To explore the impact of bacterial load and microbial colonization patterns on the clinical outcomes of periodontal surgery at deep intrabony defects. Materials and Methods: One hundred and twenty-two patients with advanced chronic periodontitis and at least one intrabony defect of >3 mm were recruited in 10 centres. Before recruitment, the infection control phase of periodontal therapy was completed. After surgical access and debridement, the regenerative material was applied in the test subjects, and omitted in the controls. At baseline and 1 year following the interventions, clinical attachment levels (CAL), pocket probing depths (PPD), recession (REC), full-mouth plaque scores and full-mouth bleeding scores were assessed. Microbial colonization of the defect-associated pocket was assessed using a DNA,DNA checkerboard analysis. Results: Total bacterial load and counts of red complex bacteria were negatively associated with CAL gains 1 year following treatment. The probability of achieving above median CAL gains (>3 mm) was significantly decreased by higher total bacterial counts, higher red complex and T. forsythensis counts immediately before surgery. Conclusions: Presence of high bacterial load and specific periodontal pathogen complexes in deep periodontal pockets associated with intrabony defects had a significant negative impact on the 1 year outcome of surgical/regenerative treatment.

    Clinical outcomes following treatment of human intrabony defects with GTR/bone replacement material or access flap alone

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 9 2004
    A multicenter randomized controlled clinical trial
    Abstract Aim: This prospective multicenter randomized controlled clinical trial was designed to compare the clinical outcomes of papilla preservation flap surgery with or without the application of a guided tissue regeneration (GTR)/bone replacement material. Materials and Methods: One hundred and twenty-four patients with advanced chronic periodontitis were recruited in 10 centers in seven countries. All patients had at least one intrabony defect of 3 mm. The surgical procedures included access for root instrumentation using either the simplified or the modified papilla preservation flap in order to obtain optimal tissue adaptation and primary closure. After debridement, the regenerative material was applied in the test subjects, and omitted in the controls. At baseline and 1 year following the interventions, clinical attachment levels (CALs), probing pocket depths (PPDs), recession, full-mouth plaque scores and full-mouth bleeding scores (FMBS) were assessed. Results: One year after treatment, the test defects gained 3.3±1.7 mm of CAL, while the control defects yielded a significantly lower CAL gain of 2.5±1.5 mm. Pocket reduction was also significantly higher in the test group (3.7±1.8 mm) when compared with the controls (3.2±1.5 mm). A multivariate analysis indicated that the treatment, the clinical centers, baseline PPD and baseline FMBS significantly influenced CAL gains. Odds ratios (ORs) of achieving above-median CAL gains were significantly improved by the test procedure (OR=2.6, 95% CI 1.2,5.4) and by starting with deeper PPD (OR=1.7, 1.3,2.2) but were decreased by receiving treatment at the worst-performing clinical center (OR=0.9, 0.76,0.99). Conclusions: The results of this trial indicated that regenerative periodontal surgery with a GTR/bone replacement material offers an additional benefit in terms of CAL gains, PPD reductions and predictability of outcomes with respect to papilla preservation flaps alone.

    Relative effectiveness of powered and manual toothbrushes in elderly patients with implant-supported mandibular overdentures

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2002
    A. Tawse-Smith
    Abstract Aim: The aim of this study was to compare the clinical effectiveness of a powered toothbrush (Braun Oral-B Plaque Remover 3-D) and a manual soft toothbrush (Oral-B Squish-grip brush) for the control of supragingival plaque and soft tissue inflammation around implants supporting mandibular overdentures. Material and methods: The study sample involved 40 edentulous subjects, aged 55,80 years, having 2 unsplinted mandibular implants supporting a complete removable overdenture opposed by a maxillary complete denture. In this single-blinded, randomised, cross-over clinical trial, two 6-week experimental phases were separated by a 2-week wash-out period. 2 weeks prior to each experimental phase (pre-entry visits), implant abutments were polished to remove all plaque and a standardised instruction in the use of the toothbrush was given. Modified plaque and bleeding indices were recorded at the start and end of each experimental period. Mean index scores at each phase were analysed using paired t -test, and the mean number of sites showing a change in plaque or mucositis were compared using the Mann-Whitney U -test. Combined data from 2 different implant systems were considered after controlling for implant type. Results: Only minor changes in plaque and bleeding scores were observed following the two test periods. There were no statistically significant differences between the manual and powered toothbrushes. Conclusion: Manual and powered brushes were found to be of comparable efficacy with regard to improvement in peri-implant bleeding and plaque indices. Zusammenfassung Zielsetzung: Untersuchung der klinischen Effektivität einer elektrischen Zahnbürste (Braun Oral-B Plaque Remover 3-D) im Vergleich zu einer weichen Handzahnbürste (Oral-B Squish-grip brush) zur Kontrolle supragingivaler Plaque und Weichgewebsentzündung an Implantaten, die Unterkiefer-Totalprothesen tragen. Material und Methoden: Das Untersuchungskollektiv bestand aus 40 zahnlosen Patienten im Alter zwischen 55 und 80 Jahren, die 2 unverblockte Unterkiefer-Implantate zur Unterstützung einer Totalprothese aufwiesen. Der Oberkiefer war jeweils mit einer total schleimhautgetragenen Prothese versorgt. In dieser einfach verblindeten, randomisierten klinischen Cross-over-Studie wurden 2 6-wöchige experimentelle Phasen von einer 2-wöchigen Auswaschperiode unterbrochen. 2 Wochen vor jeder experimentellen Phase wurden die supragingivalen Implantatflächen von sämtlicher Plaque gereinigt und die Patienten erhielten eine Instruktion im Gebrauch der Zahnbürsten. Modifizierte Plaque- und Blutungsindizes wurden zu Beginn und am Ende jeder experimentellen Phase erhoben. Die Mittelwerte für die Indizes wurden mittels des paarigen t -Tests und die Zahl der Stellen, die eine Veränderung in Plaque und Mucositis aufwiesen, wurden durch den Mann-Whitney U -Test verglichen. Die Daten für 2 Implantatsysteme wurden zusammengefasst, nachdem der Einfluss des Implantatsystems überprüft worden war. Ergebnisse: Es wurden nur geringe Veränderungen der Plaque- und Blutungsindizes am Ende beider Testphasen beobachtet. Ein statistisch signifikanter Unterschied zwischen elektrischer und Handzahnbürste konnte nicht gezeigt werden. Schlussfolgerungen: Hand- und elektrische Zahnbürsten erwiesen sich als gleich effektiv für die Verbesserung periimplantärer Plaque- und Blutungsindizes. Résumé But: Le but de cette étude était de comparer l'efficacité clinique d'une brosse à dent électrique (Plaque remover 3D de Braun Oral B) et une brosse souple manuelle (squish grip d'oral B) pour le contrôle de la plaque supra-gingivale et l'inflammation des tissus mous autour d'implants supportant des overdentures mandibulaires. Matériaux et méthodes: L'échantillon étudié comprenait 40 sujets édentés, âgés de 55 à 80 ans, ayant 2 implants mandibulaires non reliés supportant une overdenture amovible complète et une prothèse maxillaire antagoniste complète. Dans cet essai clinique croisé en aveugle simple, randomisée, 2 phases expérimentales de 6 semaines encadraient une période d'arrêt de 2 semaines. 2 semaines avant chaque phase expérimentale, (visite de pré-entrée), les piliers implantaires étaient polis afin d'éliminer toute la plaque et des instructions standardisées d'utilisation de la brosse étaient données. On notait les indices, de saignement et de plaque modifié, au début et à la fin de chaque période expérimentale. Les notes d'indices moyens à chaque phase étaient analysées par le test t apparié et le nombre moyen de sites présentant une modification de la plaque ou de la mucosite était comparé par le test U de Mann Whitney. Les données combinées des 2 systèmes implantaires étaient considérées après cotrôle pour chaque type d'implant Résultats: De minimes modifications des notes de plaque et de saignement étaient observées après les deux périodes de test. Il n'y avait pas de différences statistiques significatives entre les brosses manuelles et électriques. Conclusion: Les brosses manuelles et électriques ont une efficacité comparable du point de vue de l'amélioration des indices de saignement et de plaque peri-implantaires. [source]

    The effects of copper contraceptive intrauterine device on the uterine blood flow: A prospective transvaginal Doppler study

    JOURNAL OF CLINICAL ULTRASOUND, Issue 7 2009
    Nuray Yigit MD
    Abstract Purpose. To evaluate the hemodynamic changes by transvaginal color Doppler sonography (CDS) in the uterine vascular bed after the insertion of a contraceptive intrauterine device (CIUD) and to investigate whether those CDS findings could predict potential side effects, such as dysmenorrhea and abnormal bleeding. Method. Pulsatility index (PI), resistance index, and systole/diastole ratio (S/D) were measured in the uterine artery and its myometrial branches on 28 patients before and after the insertion of copper IUD, and a correlation with dysmenorrhea and abnormal bleeding was investigated. Result. PI and S/D values in the uterine artery increased significantly after the insertion of the CIUD (p < 0.05). Patients with increased bleeding scores after insertion of CIUD had significantly lower uterine artery PI compared with those without increased bleeding scores (p < 0.05). No statistically significant difference was detected in the Doppler flow parameters regarding dysmenorrhea scores. Conclusion. Low uterine artery PI values recorded in the early phase of the menstrual cycle in patients with a CIUD were associated with an increased bleeding risk. © 2009 Wiley Periodicals, Inc.

    A 10-year retrospective analysis of radiographic bone-level changes of implants supporting single-unit crowns in periodontally compromised vs. periodontally healthy patients

    CLINICAL ORAL IMPLANTS RESEARCH, Issue 9 2010
    Sergio Matarasso
    Abstract Aim: To compare the 10-year peri-implant bone loss (BL) rate in periodontally compromised (PCP) and periodontally healthy patients (PHP) around two different implant systems supporting single-unit crowns. Materials and methods: In this retrospective, controlled study, the mean BL (mBL) rate around dental implants placed in four groups of 20 non-smokers was evaluated after a follow-up of 10 years. Two groups of patients treated for periodontitis (PCP) and two groups of PHP were created. For each category (PCP and PHP), two different types of implant had been selected. The mBL was calculated by subtracting the radiographic bone levels at the time of crown cementation from the bone levels at the 10-year follow-up. Results: The mean age, mean full-mouth plaque and full-mouth bleeding scores and implant location were similar between the four groups. Implant survival rates ranged between 85% and 95%, without statistically significant differences (P>0.05) between groups. For both implant systems, PCP showed statistically significantly higher mBL rates and number of sites with BL,3 mm compared with PHP (P<0.0001). Conclusions: After 10 years, implants in PCP yielded lower survival rates and higher mean marginal BL rates compared with those of implants placed in PHP. These results were independent of the implant system used or the healing modality applied. To cite this article: Matarasso S, Rasperini G, Iorio Siciliano V, Salvi GE, Lang NP, Aglietta M.
