Dental Prophylaxis (dental + prophylaxis)
Selected AbstractsThe influence of a hydrogen peroxide and glycerol containing mouthrinse on plaque accumulation: a 3-day non-brushing modelINTERNATIONAL JOURNAL OF DENTAL HYGIENE, Issue 4 2009NL 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. [source] Anti-gingivitis efficacy of a stabilized 0.454% stannous fluoride/sodium hexametaphosphate dentifriceJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2005A controlled 6-month clinical trial Abstract Objective: Stannous fluoride is a broad-spectrum anti-microbial agent that has been used in dentistry as a chemical adjunct to prevent dental caries and gingivitis. The objective of this study was to assess the anti-gingivitis efficacy of a stabilized 0.454% stannous fluoride/sodium hexametaphosphate dentifrice relative to a negative control. Methods: This was a randomized, 6-month, double-blind, parallel-group gingivitis study conducted according to the guidelines for evaluating chemotherapeutic products for the control of gingivitis outlined by the American Dental Association. A stabilized 0.454% stannous fluoride/sodium hexametaphosphate dentifrice was tested against a commercially available negative control dentifrice. Following baseline measurements, subjects received a dental prophylaxis. Subjects were then instructed to brush twice daily for 60 s using their assigned product. Oral soft-hard-tissue examinations and clinical examinations using the Modified Gingival Index, Gingival Bleeding Index, and the Turesky modification of the Quigley,Hein Plaque Index were performed at baseline, 3 and 6 months post-treatment. Results: A total of 143 subjects were enrolled and 130 of them completed the 6-month study. After 6 months of product usage, the experimental group had 21.7% less gingivitis (p<0.001), 57.1% less bleeding (p<0.001), and 6.9% less plaque (p=0.01) on average compared with the negative control group. No adverse oral soft-hard-tissue effects or extrinsic tooth staining was observed in the study. Conclusion: The results demonstrate that use of the stabilized 0.454% stannous fluoride/sodium hexametaphosphate dentifrice over a 6-month period provided statistically significant reductions in gingivitis, gingival bleeding, and plaque when compared with a negative control dentifrice. [source] Influence of a SLS-containing dentifrice on the anti-plaque efficacy of a chlorhexidine mouthrinseJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 3 2004D. A. C. Van Strydonck Abstract Background: Chlorhexidine (CHX) and sodium lauryl sulphate (SLS), the most widely used detergent in dentifrice, may counteract. Consequently, studies about this interaction suggested that care is required when combining both these compounds, even when they are introduced separately into the oral cavity. The purpose of the present study was to investigate the effect of toothbrushing with a SLS-containing dentifrice in one jaw, on the plaque inhibition of a CHX mouthrinse in the opposite jaw during a 4-day study period. Methods: The study was an examiner-blind, randomised two-cell, crossover design. It used a 4-day plaque accumulation model to compare two different oral hygiene regimens with a washout period of 17 days. Sixteen healthy volunteers were enrolled in the study and received a thorough dental prophylaxis at the beginning of each 4-day test period. One jaw (upper or lower) was randomly assigned as the "study" jaw. The opposite jaw was assigned as the "dentifrice" jaw and served only to introduce the effect of brushing with a dentifrice in the study model. Two oral hygiene regimens were evaluated. During one randomly assigned test period, the "dentifrice" jaw was treated by toothbrushing with a 1.5% SLS-containing dentifrice and rinsed together with the "study" jaw with 0.2% CHX, thus forming regimen 1. As a control during the other test period, both the "dentifrice" jaw and "study" jaw were only rinsed with 0.2% CHX, forming regimen 2. No other oral hygiene methods were allowed. After 4 days of undisturbed plaque accumulation, the amount of plaque was evaluated (Silness & Löe 1964). The "study" jaw was used to study the effect of the two regimens on the level of plaque accumulation at the end of the 4-day period. Results: The overall plaque index was 0.36 for regimen 1 and 0.34 for regimen 2. There was no significant difference in plaque accumulation between the two regimens. Conclusions: Within the limitations of the present study design, it can be concluded that ordinary brushing with a 1.5% SLS-containing dentifrice (Colgate Bi-Fluor), followed by rinsing with water does not appear to reduce the level of plaque inhibition offered by a post-brushing CHX rinse. [source] Antiplaque and antigingivitis effectiveness of a hexetidine mouthwashJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2003N. C. Sharma Abstract Objective: To assess the antiplaque/antigingivitis efficacy of a hexetidine-containing mouthwash. Methods: This examiner-blind, parallel group, controlled clinical study examined the effectiveness of a hexetidine (0.1%) mouthwash both in inhibiting the development of supragingival plaque and in reducing gingivitis. One hundred and thirty-four adult subjects completed the 2-week experimental gingivitis model study. Following baseline examinations, which included plaque index, modified gingival index and gingival bleeding index, subjects received a full dental prophylaxis. Subjects were randomly assigned to one of three mouthwashes (hexetidine 0.1%, chlorhexidine 0.12% (positive control) or a 5% hydroalcohol negative control) and commenced three times daily supervised rinsing as their sole method of oral hygiene. All indices were rescored after 2 weeks. Results: Compared to the negative control group, the hexetidine group demonstrated a statistically significant inhibition and reduction of supragingival plaque and gingival inflammation with reductions of 6.3%, 33.5% and 56% for gingivitis, plaque and gingival bleeding, respectively. The results of the chlorhexidine group were used to validate the study. Conclusion: The study confirms the efficacy of a hexetidine rinse in reducing supragingival plaque and gingival inflammation. Zusammenfassung Zielsetzung: Untersuchung der Antiplaque- und Antigingivitiseffektivität einer Hexetidin-Mundspüllösung. Methoden: Diese kontrollierte klinische Studie mit verblindetem Untersucher im Parallelarm-Design untersuchte die Effektivität einer Hexitidin-Mundspüllösung (0,1%) sowohl für die Hemmung supragingivaler Plaquebildung als auch zur Reduktion der Gingivitis. 134 erwachsene Probanden beendeten die 2 Wochen dauernde Studie mit experimenteller Gingivitis. Nach der Erstuntersuchung, die die Erhebung des Plaque Index, des Modifizierten Gingival Index und des Gingivalen Blutungs Index umfasste, erhielten die Probanden eine professionelle Zahnreinigung. Den Probanden wurden randomisiert 3 Spüllösungen zugewiesen (Hexitidin 0,1%, Chlorhexidin 0,12% [positive Kontrolle] oder ein 5%iger Hydroalkohol [negative Kontrolle]) und begannen damit als alleinige Mundhygienemaßnahme 3 mal täglich unter Aufsicht zu spülen. Nach 2 Wochen wurden die Indizes erneut erhoben. Ergebnisse: Im Vergleich zur negativen Kontrolle zeigte die Hexitidin-Gruppe eine statistisch signifikante Hemmung und Reduktion der supragingivalen Plaque und gingivalen Entzündung mit Reduktionen von 6,3%, 33,5% bzw. 56% für Gingivitis, Plaque bzw. gingivale Blutung. Die Ergebnisse der Chlorhexidin-Gruppe dienten zur Validierung der Studie. Schlussfolgerung: Diese Studie bestätigt die Wirksamkeit von Hexitidin zur Reduktion supragingivaler Plaque und gingivaler Entzündung. Résumé Cette étude clinique contrôlée par groupe parallèle avec examinateur aveugle a estimé l'efficacité d'un bain de bouche à 0,1% d'héxatidine tant à inhiber le développement de la plaque sus-gingivale qu'à réduire la gingivite. Cent trente-quatre adultes ont achevé un gingivite expérimentale de deux semaines. A la suite de l'examen de base comprenant l'indice de plaque, l'indice gingival modifié et l'indice de saignement gingival, les sujets ont reçu une prophylaxie dentaire complète. Ils ont ensuite été répartis de manière randomisée pour utiliser un des trois bains de bouche suivants : héxatidine 0,1%, chlorhexidine 0,12% (contrôle positif) ou l'hydroalcool 5% (contrôle négatif), et ont commencé a effectuer un rinçage supervisé trois fois par jour comme unique méthode d'hygiène buccale. Tous les indices ont été relevés après deux semaines. Comparé au groupe négatif le groupe héxatidine montrait une inhibition et une réduction significatives de la plaque sus-gingivale et de l'inflammation gingivale avec des réductions respectives de 6,3, 33,5 et 56% pour la gingivite, la plaque dentaire et le saignement gingival. Les résultats du groupe chlorhexidine ont été utilisés pour valider cette étude. Celle-ci confirme l'efficacité de l'héxatidine à réduire la plaque dentaire sus-gingivale et l'inflammation gingivale.
