Aim The aim of this systematic review was to evaluate the efficacy of anti-plaque chemical formulations for managing gingivitis, in 6-month, home-use, randomised clinical trials ( RCTs). Material and Methods A protocol was designed, including inclusion and exclusion criteria to identify RCTs assessing gingival and/or bleeding indices. Electronic and hand-searches identified relevant papers, which were screened and evaluated for inclusion. Full-papers were retrieved and relevant information was extracted (also plaque indices), including quality and risk of bias. Mean treatment effects were calculated to obtain weighted mean differences ( WMD) and 95% confidence intervals. Results After the process of screening and selection, 87 articles with 133 comparisons, were included in the review. The additional effects of the tested products were statistically significant in terms of Löe & Silness gingival index (46 comparisons, WMD −0.217), modified gingival index ( n = 23, −0.415), gingivitis severity index ( n = 26, −14.939%) or bleeding index ( n = 23, −7.626%), with significant heterogeneity. For plaque, additional effects were found for Turesky (66 studies, WMD −0.475), Silness & Löe ( n = 26, −0.109), and plaque severity ( n = 12, −23.4%) indices, with significant heterogeneity. Conclusion Within the limitations of the present study, formulations with specific agents for chemical plaque control provide statistically significant improvements in terms of gingival, bleeding and plaque indices.

Objectives: To compare 3 mouthwashes: 0.20% chlorhexidine (CHX) with Anti‐Discoloration System (ADS), 0.20% CHX and 0.12% CHX with 0.05% cetylpyridinium chloride (CPC), in terms of reduction of plaque and gingival bleeding and side effects. Methods: Mild gingivitis patients were randomly divided into three Groups: they underwent professional oral hygiene and received instructions: oral rinse with 10 mL for 1', twice a day, 30' after tooth brushing, for 14 days. Primary outcomes were plaque and gingival bleeding, assessed with Plaque Control Record and Gingival Bleeding Index. Feedback questionnaire and spectrophotometer evaluated secondary outcomes: adverse events. Timing of the study was T0 (baseline), T1 (professional oral hygiene) and T2 (14th day after mouthwash use). Results: Sixty‐six patients were recruited, two patients dropped out, and 64 patients completed the study. PCR T1‐T2 mean variation was 30.67 (SD = 15.22; 95% CI 23.55 to 37.80; P = 0.000), 19.93 (SD = 11.03; 95% CI 14.90 to 24.95; P = 0.000) and 16.24 (SD = 15.35; 95% CI 9.60 to 22.88; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. GBI mean variation (T0‐T2) was −9.82 (SD = 9.27; 95% CI −5.48 to 14.16; P = 0.000), −19.31 (SD = 11.33; 95% CI −14.15 to −24.47; P = 0.000) and −21.13 (SD = 12.56; 95% CI −15.70 to −26.56; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. Statistical significance was found in lower efficacy of 0.2% CHX + ADS Group. Patients tolerated 0.12% CHX + CPC mouthwash better in bleeding perception (95.5%; P = 0.046), burning sensation (13.6%; P = 0.006), and mouthwash taste (100%; P = 0.000). Results on staining were no statistically significant (P = 0.106). Conclusions: Addition of CPC allows reduction of CHX percentage in mouthwash formulation while keeping equal efficacy and less side effects. ADS addition decreases CHX efficacy in reducing plaque and bleeding, while resulting more tolerated than CHX. [ABSTRACT FROM AUTHOR]

Objective The aim was to evaluate the effect of a chlorhexidine-containing brush-on gel when used as supplement to oral hygiene instructions and mechanical debridement, on peri-implant mucositis in adults. Materials and methods The study group consisted of 38 adults (48-87 years.) with peri-implant mucositis that were consecutively enrolled in three private clinics after informed consent. The study employed a double-blind controlled design with two parallel arms. After baseline registrations, oral hygiene reinforcement and mechanical debridement, the patients were randomly allocated to either a test group with once daily tooth brushing with an oral care brush-on gel containing 0.2% chlorhexidine digluconate (Cervitec Gel) or a control gel group. The duration of the intervention was 12 weeks. The primary outcome was bleeding on probing ( BOP) and secondary endpoints were local plaque score ( LPS) and pocket probing depth ( PPD). Results The groups were balanced at baseline. The daily use of the chlorhexidine-containing gel resulted in reduced BOP after 4 and 12 weeks compared with the control group ( P < 0.05). The PPD was significantly reduced ( P < 0.05) after 12 weeks compared to baseline in the test group, but not in the control group. No side effects or adverse events were reported. Conclusion The present findings indicated moderate but significant improvements of clinical parameters when mechanical debridement was combined with a self-applied oral care brush-on gel for the management of peri-implant mucositis.

Aim To evaluate the effect of self-performed mechanical plaque control ( SPC) frequency on gingival health. Methods Thirty-nine subjects exhibiting limited gingival inflammation and minimal clinical attachment loss were enrolled in a single-blind, parallel group, randomized clinical trial. The subjects that were divided into three groups were tasked to perform SPC (using tooth brush and dental floss) at 12, 24 or 48 h intervals. Gingival index ( GI), plaque index (PlI), and gingival crevicular fluid ( GCF) volume were evaluated at baseline and 30 days follow-up. Groups were compared using anova and Tukey. Results No significant differences in mean GI change were observed between the 12 and 24 h SPC intervals from baseline to 30 days (−0.06 ± 0.13 versus 0.05 ± 0.09; p = 0.11). In contrast, the 48 h interval had significantly higher mean GI change than the 12 and 24 h intervals (0.33 ± 0.17; p = 0.001). Similarly, mean PlI change was not significantly different between the 12 and 24 h SPC intervals (0.11 versus 0.28; p = 0.15), whereas SPC at 48 h-intervals yielded a significantly increased PlI (0.39; p = 0.001). Conclusions Self-performed mechanical plaque control performed at 12 h or 24 h intervals appears sufficient to maintain gingival health in subjects with no or limited clinical attachment loss.

Aim To assess the efficacy of a 0.07% cetylpyridinium chloride ( CPC) mouth rinse in the control of plaque and gingival inflammation during a 6-month period. Material and Methods Adult subjects with moderate gingivitis were selected [≥40% bleeding on marginal probing ( BOMP)]. After retrieving microbiological samples and evaluating the clinical parameters (plaque, BOMP and stain indexes), a professional prophylaxis was performed and subjects were randomly assigned to the test ( CPC mouth rinse) or to the placebo group. Subjects were re-assessed after 3 and 6 months. Results A total of 67 patients (35 test, 32 placebo) were included in the analysis. At 6 months, intra-group significant plaque reductions were observed in the test group (0.691, p < 0.001), but not in the placebo (0.181, p = 0.653). At 6 months, the mean BOMP values were lower in the test group ( p = 0.052). Changes between baseline and 6 months were significantly higher in the test group both for plaque ( p = 0.002) and BOMP ( p = 0.037) when compared with the placebo. A microbiological impact was observed in the test group, especially for Prevotella intermedia. Conclusion The evaluated 0.07% CPC-based mouth rinse, used three times per day adjunctively to mechanical tooth cleaning, prevents plaque accumulation and gingival inflammation, as compared to the placebo, for at least 6 months.
