    The influence of a hydrogen peroxide and glycerol containing mouthrinse on plaque accumulation: a 3-day non-brushing model

    NL Hoenderdos
    Abstract:, Aim:, To evaluate the inhibition of plaque growth by an experimental mouthrinse (BioXyl®) based on hydrogen peroxide/glycerol. Design:, It was a double-blind, randomized study involving 40 volunteers in good general health. At the start of the trial, all participants received a dental prophylaxis to remove all plaque deposits. During the next 3 days subjects refrained from any mechanical oral hygiene procedure, except for the allocated mouthrinse being either the hydrogen peroxide (H2O2; 0.013% H2O2/0.004% glycerol) or the placebo without H2O2. At the third day of appointment, plaque levels were assessed at six sites per tooth. Results:, The test group had a mean overall plaque score of 2.66 and the placebo group of 2.70. The difference in plaque scores between the two groups was not statistically significant. Conclusions:, The results of this pilot study showed that there was no statistically significant difference between the H2O2/glycerol group and the placebo group with respect to plaque inhibition within this study design.

    Experiences of oral care in patients with haematological malignancies or head and neck cancer

    The aim of the present study was to investigate cancer patients' experiences of oral hygiene information, oral care and self-care, information on oral complications, examination of the oral cavity, and ability to eat and drink during cancer treatment, and to explore patient attitudes to oral examination and oral hygiene. The sample consisted of 41 consecutive patients treated with radiotherapy for head and neck cancer (n = 18) or with chemotherapy for haematological malignancies (n = 23). Patients were interviewed at the end of radiotherapy or the second/third chemotherapy cycle. Compared with patients receiving chemotherapy, those who received radiotherapy had significantly more often visited hospital dentistry, been informed about oral complications and oral hygiene, received instructions in oral hygiene procedures, and been examined by hospital staff. More of the radiotherapy patients experienced oral symptoms and difficulties to eat and drink during treatment. There were no significant differences between the groups with regard to patient experiences of the oral hygiene procedures. Only one patient objected to having hospital staff discuss oral hygiene procedures, and three did not want hospital staff to examine their oral cavity. Patients undergoing radiotherapy or chemotherapy need to be monitored during treatment with regard to their oral status and oral symptoms and complications. There are no acceptable reasons for allowing patients to suffer from oral symptoms that can be reduced. [source]

    Aim:, The aim of this study was to investigate oral health and oral implant status in a group of edentulous patients receiving long-term residential or nursing care (LTC), all of whom had implant-supported fixed or removable dental prostheses. Material and methods:, A dental examination was performed on a total of 3310 patients receiving LTC and from this population 35 edentulous patients in whom dental implants had been placed formed the cohort for this study. All examinations were performed by a specialist in hospital dentistry and took place in the patients' own home environment. Oral health was assessed by means of a protocol which evaluated oral hygiene status, possible oral mucosal inflammation and oral mucosal friction levels. Any problems with the implant-supported prosthesis, implant mobility or other complications were also assessed. In addition, patients were asked about any oral symptoms and their usual oral hygiene procedures. Results:, About half of the subjects (17/35) were registered as having no/mild inflammation with 18 of 35 having moderate/severe inflammation. Twelve of the 35 patients had good/acceptable oral hygiene and 23 of 35 had poor/bad oral hygiene. Twenty-one of the 35 patients depended on help from the nursing personnel for their daily oral hygiene procedures. Obvious problems with food impaction were noted in 11 patients. A total of 229 implants had been placed in 43 jaws supporting 40 full arch-fixed prostheses and three implant-borne overdentures. There was no evidence of mobility or fractures of either the implants or the prostheses. Fifteen implants showed some exposed screw threads. Pus was exuding from one implant site and general peri-implant gingival hyperplasia was noted in two patients. Twenty-four patients were completely satisfied with the function and appearance of their implant-supported prostheses. Two patients were totally dissatisfied. Conclusion:, This study indicates that oral implant therapy can be considered as a treatment of choice in elderly patients, even if oral hygiene is sub-optimal. [source]

    Oral hygiene and the need for treatment of the dependent institutionalised elderly

    Objective:, To assessing the oral hygiene and treatment needs of a geriatric institution in southern France. Background:, For various reasons, the care demand from elderly people is low and difficult to determine, whereas their oral status would need long and complicated treatments. Materials and methods:, From 2003 to 2004, a cross-sectional study of 321 elderly patients was conducted at several geriatric services of Montpellier, France. The clinical evaluation of dental status was recorded together with medical information. Dental and prosthetic hygiene, status of dentures, caries experience, dependence conditions and treatment needs were evaluated. Results:, The prevalence of edentulism was 27%, with no gender difference (23% of the men and 29% of the women). Among them, 16.7% (upper jaw) and 18.1% (lower jaw) were totally edentulous with no denture. The mean number of decayed and missing teeth was 3.7 for men and 2.8 for women and 21.5 for men and 21.0 for women, respectively. The mean number of filled teeth was 0.8 for men and 1.3 for women, with no statistical difference according to gender for the three indexes. Most of the subjects needed prostheses (53%), 45.1% extractions and 30.6% conservative treatments. Only 2.4% did not need any treatment. Conclusion:, The prevalence of edentulism was relatively low, while the need for prosthodontic rehabilitation, especially for men, was still very high. The dental hygiene was globally inadequate. This evaluation emphasises the care demand and the need for help in oral hygiene procedures for the dependent institutionalised elderly. [source]

    A study into the plaque-inhibitory activity of experimental toothpaste formulations containing antimicrobial agents

    J. Moran
    Abstract Background/Aims: The use of specific antimicrobial agents in toothpastes may help reduce plaque and gingivitis. There would also appear to be some value in formulating products that contain combinations of such agents that may potentiate any activity present. The aims of this exploratory and pragmatic study were twofold:- (1) exploratory: to compare the effects on plaque re-growth of two zinc citrate/triclosan formulations, one of which contained bromochlorophene and hence demonstrate any additional beneficial effects produced by the addition of the phenol. (2) pragmatic: to assess whether both pastes were significantly better than a benchmark control, proprietary fluoride toothpaste at inhibiting plaque formation. Methods: Following an initial prophylaxis to remove all plaque and calculus, toothpaste slurry rinses were used over a 96 h period by 24 volunteers, while omitting all other oral hygiene procedures. After 24, 48 and 96 h, plaque was measured by plaque area and by plaque index. For comparative purposes, a conventional commercial fluoride toothpaste rinse was also used as a benchmark control in this triple cross-over double-blind study. Results: With one exception, comparisons between the three pastes failed to show any significant differences in plaque accumulation at 96 h whether assessed by plaque index or area. At this time period, significantly more plaque was seen with the zinc citrate paste without bromochlorophene, compared with that of the control paste. Conclusions: The findings from this study failed to demonstrate a plaque-inhibitory action from the two novel formulations beyond that of a conventional benchmark toothpaste, although overall levels of plaque formed by the volunteers, especially on the control paste were generally lower than in previous studies. Nevertheless, it remains to be determined whether the test formulations could exert a direct anti-inflammatory action against gingivitis by way of the triclosan delivery system. Neither test formulation was subsequently marketed. [source]

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

    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]

    Clinical and microbial evaluation of a histatin-containing mouthrinse in humans with experimental gingivitis: a phase-2 multi-center study

    Thomas Van Dyke
    Abstract Objective: P-113, a 12 amino acid histatin-based peptide, was evaluated in a mouthrinse formulation for safety and efficacy in a phase 2 multi-center clinical study. Method: 294 healthy subjects abstained from oral hygiene procedures and self-administered either 0.01% P-113, 0.03% P-113 or placebo mouthrinse formulations twice daily over a 4-week treatment period. During this time, the safety, anti-gingivitis, and anti-plaque effects of P-113 were evaluated. Results: There was a significant reduction in the change from baseline to Day 22 in bleeding on probing in the 0.01% P-113 treatment group of the intent to treat population (p=0.049). Non-significant trends in the reduction of the other parameters were observed in this population (p0.159). A sub-group of subjects which developed significant levels of disease within the four-week timeframe of the study was identified based on baseline gingival index scores 0.75. Significant findings were observed for bleeding on probing, gingival index and plaque index within this population (p<0.05). There were no treatment-related adverse events, and there were no adverse shifts in supragingival microflora during the study. Significant amounts of the peptide were retained in the oral cavity following rinsing. Conclusion: These data suggest that P-113 mouthrinse is safe and reduces the development of gingival bleeding, gingivitis and plaque in the human experimental gingivitis model. Zusammenfassung Ziel: In einer klinischen Phase-2 Multicenter-Studie wurde P-113, ein 12-Aminosäure-Histatin basierendes Peptid bezüglich Sicherheit und Effektivität in einer Mundspüllösung evaluiert. Methode:Für eine Behandlungszeitraum von 4 Monaten enthielten sich 294 Personen den Mundhygienemaßnahmen und spülten 2× täglich entweder mit 0.01% P-113, 0.03% P-113 oder mit einer Plazebolösung. Während dieser Zeit wurden die Sicherheit von P-113 sowie sein anti-Gingivitis- und sein anti-Plaqueeffekt evaluiert. Ergebnisse: In der 0.01% P-113-Behandlungsgruppe, der Population die behandelt werden sollte gab es eine signifikante Reduktion (p=0.049) der Veränderung zwischen Ausgangswert und Tag-22-Wert der Sondierungsblutung. In dieser Population wurden nichtsignifikante Trends in der Reduktion der anderen Parameter beobachtet (p0.159). Eine Untergruppe der Personen, welche während des vierwöchigen Zeitraumes ein signifikantes Erkrankungsniveau entwickelte, wurde auf der Grundlage eines Ausgangswertes für den Gingiva-Index von 0.75 identifiziert. Innerhalb dieser Population wurden signifikante Ergebnisse (p<0.05) für die Sondierungsblutung, den Gingiva-Index und den Plaque-Index beobachtet. Während dieser Studie gab es keine durch die Behandlung verursachten Nebenwirkungen und es gab keine unerwünschte Verschiebung der supragingivalen Mikroflora. Nach dem Spülen verblieb eine signifikante Menge des Peptids in der Mundhöhle. Schlussfolgerung: Diese Daten lassen annehmen, dass eine P-113-Mundspülössung sicher ist und die Entwicklung der Gingivablutung, Gingivitis und Plaque in einem humanen experimentellen Gingivitismodel hemmt. Résumé But: Le P-113, un peptide contenant de l'histatine a étéévalué dans un bain de bouche pour sa sécurité et son efficacité dans une étude multicentrique phase 2. Méthode. 294 sujets sains ont arrête toute hygiène buccale et se sont rincé avec soit 15 ml de P-113 0.01%, 15 ml de P-113 0.03% ou 15 ml d'une solution placebo 2× par jour durant une période de 4 semaines. Pendant ce temps, les effets anti-plaque et anti-gingivite, la sécurité ont étéévalués. Résultats: Il y avait une réduction significative entre l'examen de départ et le jour 22 dans le saignement au sondage dans le groupe P-113 0.01% (p=0.049). Aucune tendance significative dans la réduction des autres paramètres n'a été observée dans cette population (p0.159). Un sous-groupe de sujets qui développaient des niveaux significatifs de maladie durant ces 4 semaines a été identifié sur base de leur indice gingival initial 0.75. Des découvertes significatives ont été observées pour le saignement au sondage, l'indice gingival et l'indice de plaque dentaire dans cette population (p<0.05). Il n'y a eu aucun signe négatif dû au traitement ni aucune variation négative dans la flore sus-gingivale durant l'étude. Des quantités significatives du peptide ont été retenues dans la cavité buccale après rincage. Conclusion: Ces donnés suggèrent que le rincage au P-113 est sûr et réduit le dévelopement du saignement gingival, la gingivite et la plaque dentaire dans le modèle de la gingivite expérimentale humaine.

    A clinical study to compare the efficacy of 2 electric toothbrushes in plaque removal

    Christof E. Dörfer
    Abstract Objectives: To compare the cleaning efficacy of a powered toothbrush with 3-dimensional brush head action (Braun Oral-B 3D Plaque Remover D15) and a high-speed "microtation" brush with an additional "microbrush® -clip" (Rowenta Dentasonic MH921S). Material and Methods: 82 healthy subjects took part in the study. After a familiarization period of 8 days, the subjects abstained from all oral hygiene procedures for 48 h. After plaque was scored, the subjects brushed their teeth under supervision with the two brushes according to a split-mouth design. Immediately after brushing, subjects completed a questionnaire and plaque was scored again. Results: The overall plaque scores were found to be significantly reduced from 3.05±0.60 to 1.96±0.63 by the D15 and from 3.02±0.58 to 2.24±0.64 by the Dentasonic (p<0.05). The proximal surface plaque scores were reduced from 3.20±0.63 to 2.17±0.69 by the D15 and from 3.17±0.60 to 2.44±0.69 by the Dentasonic. The relative plaque reduction was overall 36.6±12.2% for the D15 compared to 26.1±13.5% for the Dentasonic and at proximal surfaces, 33.1±12.3% and 23.2±13.0%, respectively. 75% of the subjects stated that they would prefer to keep the D15. Conclusions: Both brushes were able to remove a significant amount of plaque, but the D15 was significantly more effective compared to the Dentasonic. The additional "microbrush® -clip" for the proximal embrasures failed to improve plaque removal from these tooth surfaces, compared to the D15 alone. Zusammenfassung Hintergrund: Vergleich der Reinigungseffizienz von einer elektrischen Zahnbürste mit dreidimensionaler Bürstenkopfaktion (Braun Oral-B 3D Plaqueentferner D 15) mit einer hochtourigen "mikrorotierenden" Bürste und mit einem zusätzlichen "Mikrobürsten® -Clip" (Rowenta Dentasonic MH921S). Material und Methoden: 82 gesunde Personen nahmen an der Studie teil: Nach einer Eingewöhnungsperiode von 8 Tagen enthielten sich die Personen aller oralen Hygieneprozeduren für 48 Stunden. Nachdem die Plaque aufgezeichnet worden war, reinigten die Personen ihre Zähne unter Aufsicht mit den zwei Bürsten entsprechend eines split-mouth Design. Sofort nach der Reinigung füllten die Personen einen Fragebogen aus, und die Plaque wurden erneut aufgezeichnet. Ergebnisse: Die Gesamtplaquescores wurden signifikant von 3.05±0.60 auf 1.96±0.62 mit der D 15 und von 3.02±0.58 auf 2.24±0.64 mit der Dentasonic reduziert (p<0.05). Die Plaquescores für die approximalen Flächen wurden von 3.20±0.63 auf 2.17±0.69 mit der D 15 und von 3.17±0.60 auf 2.44±0.69 mit der Dentasonic reduziert. Die relative Plaquereduktion betrug insgesamt 36.6±12.2% bei der D 15 verglichen mit 26.1±13.5% bei der Dentasonic, und für die approximalen Flächen 33.1±12.3% sowie 23.2±13.0%. 75% der Personen sagten, daß sie die D 15 bevorzugen würden. Schlußfolgerungen: Der Gebrauch beider Bürsten reduzierte signifikant die Plaque, aber die D 15 war signifikant effektiver verglichen mit der Dentasonic. Der zusätzliche "Mikrobürsten® -Clip" für die approximalen Regionen verbesserte die Plaqueentfernung an diesen Zahnflächen nicht verglichen mit der D 15 allein. Résumé But: L'objectif de cette étude a été de comparer l'efficacité de nettoyage d'une brosse à dents électrique avec une tête pouvant effectuer un nettoyage en 3 dimensions (Braun Oral-B 3D Plaque Remover D 15) et une brosse effectuant des micro-rotations à grande vitesse avec une microbrush® -clip supplémentaire (Rowenta Dentasonic MH921S). Matériaux et méthodes: 82 sujets sains ont pris part à cette étude. Après une période de familiarisation de 8 jours, les sujets ont arrêté tous processus d'hygiène buccale pendant 48 h. Après que l'indice de plaque ait été enregistré, les sujets ont brossé leurs dents sous surveillance avec 2 brosses suivant un modèle de bouche divisée. Immédiatement après le brossage, les sujets ont rempli un questionnaire et l'indice de plaque a étéà nouveau enregistré. Résultats: Les scores d'indice de plaque généraux ont été réduits de manière significative de 3.05±0.60 à 1.96±0.63 par la D15 et de 3.02±0.58 à 2.24±0.64 par la Dentasonic (p<0.05),. Les scores d'indice de plaque proximale ont été réduits de 3.20±0.63 à 2.17±0.69 par la D15 et de 3.17±0.60 à 2.44±0.69 par la Dentasonic. La réduction de plaque dentaire relative était en général de 36.6±12.2% pour la D15 comparée à 26.1±13.5% pour la Dentasonic et au niveau des surfaces proximales de 33.1±12.3% et 23.2±13%. 75% des sujets ont déclaré vouloir garder la D15. Conclusions: Les deux types de brosses étaient à même d'enlever une quantité significative de plaque dentaire, seulement la D15 s'avérait significativement plus efficace. La microbrosse-clip® additionnelle ne parvenait pas à améliorer l'élimination de plaque dentaire au niveau des embrasures proximales comparée à la D15. [source]

    Effect of an essential oilcontaining antiseptic mouthrinse on plaque and salivary Streptococcus mutans levels

    D. H. Fine
    Abstract Background: Clinical studies in which antimicrobial mouthrinses were shown to have significant antiplaque activity most frequently have used gingivitis as the clinically relevant endpoint. However, there is evidence to suggest that mouthrinses containing active agents effective against Streptococcus mutans, such as chlorhexidine, may also have a rôle in inhibiting dental caries. This clinical study was conducted to determine the effect of 2×-daily rinsing with an essential oilcontaining antiseptic mouthrinse (Listerine® Antiseptic) on levels of recoverable S. mutans and total streptococci in supragingival interproximal plaque and in saliva. Additionally, a follow-up in vitro study is reported which determined whether a differential susceptibility to the antiseptic mouthrinse exists among different strains of streptococci. Method: Following baseline saliva and plaque sampling for quantification of recoverable S. mutans and total streptococci, 29 qualifying subjects were randomly assigned either the essential oil mouthrinse or a sterile water control. They rinsed with 20 ml for 30 s 2×daily for 11 days and once on the 12th day, in addition to their usual oral hygiene procedures. On day 12, saliva and plaque samples were again collected and microbiological quantification performed. The procedures were repeated with the alternate rinse after a 1-week washout period. Results: The essential oil mouthrinse produced respective reductions of 69.9% and 75.4% in total recoverable streptococci and in S. mutans in plaque, and corresponding reductions of 50.8% and 39.2% in saliva. The in vitro study revealed that streptococci from the mutans group were more susceptible to the bactericidal activity of the essential oil mouthrinse than streptococci from the mitis group. Conclusions: As antimicrobial mouthrinses are most frequently recommended to patients whose mechanical oral hygiene procedures are not adequate for the control of supragingival plaque and gingivitis, this study provides an additional rationale for the inclusion of the essential-oil mouthrinse as an adjunct to daily oral hygiene procedures.

    An outbreak of HBV and HCV infection in a paediatric oncology ward: Epidemiological investigations and prevention of further spread

    Uga Dumpis
    Abstract Hospital-acquired hepatitis B (HBV) and C virus (HCV) infections continue to occur despite increased awareness of this problem among the medical community. One hundred six patients were infected in a haematology oncology ward for children, over the time period 1996 to 2000. Serum samples from 45 such patients and 3 from infected medical personnel were used for nucleic acid amplification. HBV core, as well as HCV core and hypervariable region 1 (HVR1) nucleotide sequences, were analysed by phylogenetic tree analysis, in order to characterise the epidemiological pattern of viral transmission on the ward. Samples from 32 patients were positive for HBV-DNA or HCV-RNA by PCR. Ten patients were positive for both markers. Seventeen out of twenty-three HCV core gene sequences were found to be evolutionarily related and clustered separately from other local sequences in the phylogenetic tree, indicating nosocomial transmission. This was confirmed by analysis of HVR1 gene sequences. One nurse and one physician from the ward were HCV RNA positive, but their HCV sequences were not related evolutionarily to those of the patient cluster. Fifteen out of nineteen HBV core gene sequences were also clustered together and were positioned separately in the relevant tree. Epidemiological investigation excluded a common source infection and indicated that spread of infection was most likely due to inappropriate infection control measures on the ward. No obvious risk factors for transmission were identified during the retrospective survey in patients with related sequences, except use of multidose vials for saline and poor staff compliance with routine hand hygiene procedures. The preventive measures that were introduced reduced the incidence of infection significantly. No new cases of HBV infection and only three anti-HCV seroconversions occurred over a period of 19 months. The introduction and maintenance of strict prevention measures over a 2 year period, combined with HBV vaccination, reduced significantly the incidence of new HCV and HBV infections. J. Med.

    Patient evaluation of treatment with fixed implant- supported partial dentures

    S.-W. Yi
    The aim of this study was to analyse the patient evaluation of functional treatment outcome in 40 periodontally compromised patients who received implant-supported prostheses (ISPs) as part of the total treatment. The treatment protocol comprised periodontal treatment, extraction of teeth with poor prognosis, placement of dental titanium implants, and after healing, insertion of fixed ISPs. Five of the patients became edentulous in one jaw after extraction of all teeth and received a complete ISP, whereas 35 patients became partially edentulous after extraction of some teeth, 12 receiving a partial ISP on , 3 implants, and 23 one on two implants. The follow-up period was on average 1,8 years after the connection of the prostheses, which provided the patients a dentition with a mean of 12 occluding dental units. The first author (S.-W. Yi) performed all implant treatment. Patients' opinions on oral functions , mastication, phonetics, oral hygiene, chewing comfort and aesthetics , were evaluated by means of a questionnaire both before implant installation and at the last follow-up. A control group of 30 subjects with a healthy dentition of 14 occluding natural pairs of teeth answered the same questionnaire on one occasion. A great majority of the patients were extremely satisfied with the oral function after treatment and experienced the ISPs as ,natural teeth'. There was no significant difference between the three treatment groups and the control group for mastication, phonetics, chewing comfort and aesthetics. Patients with ISPs reported a small but significantly greater difficulty with oral hygiene procedures than the controls with natural teeth. Most patients said that they would undergo the treatment again, if necessary, and recommend it to others. It was concluded that the rehabilitation of the periodontally compromised patients, including ISPs on osseointegrated dental titanium implants, resulted in subjectively improved and satisfactory oral function.
