Review
OBJECTIVES
A systematic review of published data was conducted with the aim of assessing the effects of xylitol consumption on the amount of dental plaque.
MATERIALS AND METHODS
Electronic and hand searches were performed to find clinical studies concerning the effects of xylitol chewing gum or candies on dental plaque. Prospective randomized controlled clinical trials published between 1971 and 2020 conducted in healthy subjects were included in the review.
RESULTS
The initial search identified 424 xylitol articles. After applying inclusion and exclusion criteria, altogether 14 articles (16 studies) were reviewed. The review identified 12 of the total of 14 xylitol chewing gum studies as having fair or high quality. In 13 of the 14 chewing gum studies, xylitol gum decreased plaque accumulation. In six studies, xylitol gum chewing decreased plaque compared to sorbitol gum, and in three studies compared to gum base/no gum. In three fair-quality studies conducted with xylitol candies, plaque accumulation did not change.
CONCLUSIONS
Habitual xylitol gum chewing appears to show plaque-reducing effects that differ from those of sorbitol gum. This suggests specific effects for xylitol on plaque accumulation. Xylitol candies appear not to decrease plaque. The heterogeneity of the studies warrants further research. Clinical relevance Habitual xylitol gum chewing is likely to decrease plaque.

Meta-Analysis Review
The efficacy of an oscillating-rotating power toothbrush compared to a high-frequency sonic power toothbrush on parameters of dental plaque and gingival inflammation: A systematic review and meta-analysis.
AIM
To establish the efficacy of oscillating-rotating power toothbrush (OR-PTB) compared to high-frequency sonic power toothbrush (HFS-PTB) on improving parameters of plaque and gingival inflammation. Safety and participants' preference were secondary interests.
MATERIALS AND METHODS
MEDLINE-PubMed and Cochrane-CENTRAL databases were searched, up to April 2021. Inclusion criteria were (randomized)controlled clinical trials that evaluated healthy humans brushing with an OR-PTB compared to a HFS-PTB. Evaluation for a minimum of 4 weeks, of one or more of the following parameters: plaque index scores (PI), bleeding scores (BS), number of bleeding sites (NoB) and gingival index scores (GI).
RESULTS
Thirty two publications involving 38 comparisons were included after the independent screening. The descriptive analysis showed that in 54% of the comparisons, a significant difference in favour of the OR-PTB was found for PI, BS and GI scores. The Quigley and Hein index showed a significant difference of means (DiffM) between the end scores (DiffM 0.13, 95% CI [0.05;0.21] p < 0.001), as well as for the Rustogi-modified Navy index (DiffM 0.01, 95% CI [0.01;0.03] p = 0.002). This is in line with the meta-analysis for BS (DiffM 0.09, 95% CI [0.03;0.14] p = 0.003), for which the results were in favour of the OR-PTB and considered potentially clinically relevant. NoB showed a significant difference in favour of the OR-PTB for the end scores (DiffM 3.61, 95% CI [2.63;4.58] p < 0.00001). No difference in safety was indicated, 78% of participants preferred the OR-PTB.
CONCLUSION
For patients to maintain good plaque control and improve gingival health, there is a small but significant difference based on longer-term studies between OR-PTB and HFS-PTB. This difference is potentially clinically relevant.

is a typical shrub from Brazil that has been used in traditional medicine. This is a systematic review on the effect of for controlling dental plaque, gingivitis, and periodontitis. A database search through May 2021 in Medline/PubMed, SCOPUS, BVS, and Web of Science identified 711 reports of which 17 met our inclusion criteria. Five randomized controlled trials and three animal studies were included that compared -based products (toothpaste, mouthrinse, and gel) to cetylpyridinium chloride, chlorhexidine, and placebo products. Among the human studies, a significant antiplaque effect after treatment with -based products was observed in three studies and an antigingivitis effect in two studies, similar to chlorhexidine-based products. One study found superior dental plaque reduction compared to cetylpyridinium chloride mouthrinse. Only one study testing a gel found no antiplaque effect. Among the animal studies, an mouthrinse significantly reduced calculus in two studies, inflammatory infiltrate in one study, and plaque bacteria and gingivitis in one study. An gel significantly reduced alveolar bone loss and inflammatory response in one study in which mice were submitted to ligature-induced periodontal disease. In general, -based products were effective in reducing dental plaque and calculus formation, as well as clinical signs of gingivitis. As most studies present methodological limitations, these results should be interpreted carefully. Further clinical trials with greater methodological accuracy and control of biases are necessary for the use of -based products in humans to be viable in clinical practice.

Review
OBJECTIVES
Professional oral hygiene is essential to prevent peri-implant disease. Appropriate instruments should be employed for implant-supported restorations: they should effectively remove deposits without damaging dental implant surface. The aim of the present systematic review is to investigate the efficacy and safety of erythritol air-polishing in implant-supported rehabilitations, compared to alternative hygienic techniques.
MATERIALS AND METHODS
The guidelines reported in the indications of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) were employed for this systematic review. The focused question was: 'what is the effect of erythritol air-polishing on dental implant surfaces regarding its cleansing efficacy and/or safety?' The final online search was conducted on 13 August 2023; MEDLINE-PubMed, Scopus and Cochrane Library were employed. Comparative in vitro or in vivo original studies were included.
RESULTS
The initial database search yielded 128 entries; the final selection comprised 15 articles. The risk of bias was evaluated using the Newcastle Ottawa scale (NOS), the Cochrane Handbook for Systematic Reviews of Interventions, GRADE method. Ultrasonic scaling with PEEK tips, glycine air-polishing and cold atmospheric plasma were the devices most frequently compared to erythritol powder in the included studies. Erythritol air-polishing appeared to be significantly more effective in reducing biofilm compared to other treatments, without causing any significant damage to the implant surface and peri-implant tissues, promoting a good biological response.
CONCLUSION
Erythritol air-polishing showed promising results for professional oral hygiene in implant-supported restorations. According to this systematic review, it is effective and safe for removing biofilm from titanium dental implants.

Meta-Analysis
BACKGROUND
Mouthwashes were convenient adjuncts to mechanical cleaning procedures. This review aimed to evaluate the efficacy of mouthwashes on oral microorganisms and gingivitis in orthodontic patients.
METHODS
By April 16, 2022, multiple databases and grey literature were searched based on the PICOS strategy. Randomized controlled trials in orthodontic patients evaluating the efficacy of mouthwashes with at least one microbial parameter and/or plaque- and/or gingival inflammation-related index were included. Relevant data were extracted, and the risk of bias was evaluated using Cochrane's tool. Individual mean and standard deviation of the outcomes in mouthwashes and placebos/blank controls were pooled to estimate the weighted mean differences (WMDs) and 95% confidence intervals (95%CIs). Sensitivity analysis, and certainty of evidence were evaluated.
RESULTS
Of 1684 articles, 32 studies satisfied the eligibility criteria, and nine were included for meta-analysis. Missing outcome data was the primary source of bias. Compared to blank controls, the short-term application of fluoride mouthwashes significantly reduced the colony counts of Mutans streptococci (MS), while the long-term application may not be effective. Compared to placebos or blank controls, Chlorhexidine mouthwashes significantly reduced the colony counts of multiple microorganisms in the short-term. Compared to placebos or blank controls, herbal mouthwashes showed the inhibitory effect of MS in the short-term, with some results lacking statistical significance. After meta-analysis, significant lower plaque- and gingival inflammation-related indexes were observed in the Chlorhexidine mouthwashes groups [Gingival Index: WMD = -0.45, 95%CI = -0.70 to -0.20 (placebos as control); WMD = -0.54, 95%CI = -0.96 to -0.13 (blank controls); Plaque Index: WMD = -0.70, 95%CI = -1.12 to -0.27 (blank controls)]. Significant lower gingival inflammation-related indexes were observed in the herbal mouthwashes groups [Gingival Index: WMD = -0.20, 95%CI = -0.32 to -0.09 (blank controls)].
CONCLUSIONS
The short-term application of fluoride mouthwashes may reduce the colony counts of cariogenic bacteria, but the long-term effect is not evident. Chlorhexidine may reduce the colony counts of multiple microorganisms in the short-term. Short-term application Chlorhexidine and herbal mouthwashes may effectively reduce plaque- and gingival inflammation-related indexes. However, the risk of bias, inconsistency, and imprecision in the included studies may reduce the certainty of the evidence.

Meta-Analysis Review
AIM
To evaluate the efficacy of adjunctive therapies in reducing gingivitis and plaque by means of a systematic review of randomized clinical trials (RCTs).
MATERIAL AND METHODS
A search protocol was designed to identify 6-month RCTs that investigated the efficacy of adjuncts to mechanical plaque control on gingivitis and plaque. Following screening, relevant information was extracted, and quality and potential risk of bias were estimated. Mean treatment differences were calculated to obtain standardized mean differences and weighted mean differences (SMD and WMD) as appropriate.
RESULTS
Meta-analyses included 70 studies of adjunctive antiseptics. Compared with mechanical plaque control alone, adjuncts yielded statistically significant reductions in gingival index (n = 72; SMD = -1.268; 95% CI [-1.489; -1.047]; p < .001; I = 96.2%), bleeding (%) (n = 26, WMD=-14.62%; 95% CI [-18.01%; -11.23%]; p < .001; I = 95.1%), plaque index (n = 93, SMD = -1.017; 95% CI [-1.194; -0.840]; p < .001; I = 95.3%) and plaque (%) (n = 23; WMD = -18.20%; 95% CI [-24.00%; -12.50%]; p < .001; I = 96.9%). Mouthrinses resulted in greater reductions in per cent plaque compared with dentifrices (meta-regression, coefficient = 13.80%; 95% CI [2.40%; 25.10%]; p = .020). The antiseptic agents were similarly effective in reducing gingivitis and plaque in patients with dental plaque-induced gingivitis (intact periodontium) or previously treated periodontitis with gingival inflammation.
CONCLUSION
Adjunctive antiseptics in mouthrinses and dentifrices provide statistically significant reductions in gingival, bleeding and plaque indices.

Meta-Analysis
White spot lesions, plaque accumulation and salivary caries-associated bacteria in clear aligners compared to fixed orthodontic treatment. A systematic review and meta- analysis.
OBJECTIVE
To analyse the available evidence regarding the incidence and severity of white spot lesions (WSLs), plaque accumulation and salivary caries-associated bacteria(SCB) in clear aligners (CA) verses conventional fixed (CF) orthodontic appliances.
METHODS
Electronic searches of MEDLINE, Scopus, Embase, Google Scholar, Clinical trial registry, OpenGrey and ProQuest were done for all relevant studies. Eligibility criteria were; Randomized Controlled Trials and Non-Randomized Studies that compared the incidence and severity of WSLs, plaque accumulation and SCB between CA and CF appliances in patients undergoing orthodontic treatment. The risk of bias(ROB) and certainty of evidence was assessed independently by two reviewers using Cochrane's ROB and GRADEpro, respectively. Standardized mean difference (SMD) was used to estimate the effect size using STATA 17 software.
RESULTS
A total of 14 studies met the eligibility criteria, and eight were suitable for meta-analysis. The qualitative results showed lower incidence and severity of WSLs, plaque accumulation, and SCB in CA group compared to CF appliances. The pooled results showed significantly lower plaque accumulation(SMD - 1.58;95%CI:-2.57,0.58;p = 0.002) in CA compared to CF appliances.
CONCLUSIONS
A moderate-quality evidence reveals less plaque accumulation and less SCB in CA, which might be related to the reduced incidence and severity of WSLs associated with CA when compared with CF appliances. However, the results of the present study should be interpreted with caution given the high ROB among some of the included studies as well as the marked heterogeneity across the studies.
CLINICAL RELEVANCE
For patients who can be treated with either CA or CF appliances, CA may be a better choice concerning oral health.

To evaluate the effect of herbal mouthrinses as an adjuvant to oral hygiene on dental plaque and gingival inflammation in subjects with gingivitis. Searches were conducted in the PubMed/MEDLINE, Cochrane-CENTRAL, EMBASE, Web of Science, LILACS/BIREME, Clinical Trials Registry and grey literature for Randomised Clinical Trials (RCTs) published up to April 2018 without language restrictions. From 4,013 paper found, 20 studies met the eligibility criteria and were included. The herbal mouthrinses achieved significant reductions in dental plaque and gingival inflammation compared to placebo rinses. Five herbal products (Camelia sinensis, Azadirachta indica, Anacardium occidentale Linn, Schinus terebinthifolius and Curcuma longa) showed better results than chlorhexidine in dental plaque and gingival inflammation reductions. However, the unclear risk of bias of most included RCTs precludes definitive conclusions. Therefore, it is necessary to improve the design of future RCT in other reduced potential bias that may affect the degree of precision of treatment outcomes in order to evaluate the effect size and clinical relevance of herbal mouthrinses.

Meta-Analysis
BACKGROUND
The aim of this study was to systematically review and analyze the difference in efficacy of oscillating-rotating toothbrushes compared with other powered toothbrushes.
METHODS
The authors performed a systematic search of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The authors used the population, intervention, comparison, and outcome format to develop a search strategy to answer the study question. The authors searched PubMed-MEDLINE databases. Inclusion criteria were randomized controlled clinical trials comparing oscillating-rotating (OR) toothbrushes with other powered toothbrushes published from January 1, 2009 through March 1, 2019.
RESULTS
The authors' search resulted in 454 articles; 21 articles were downloaded for review, 15 articles were included in the report, and 12 could be used for meta-analysis. All of the studies were randomized controlled clinical trials that assessed plaque removal and gingival inflammation indexes. Results of the meta-analysis of the randomized controlled clinical trials showed that OR toothbrushes had superior, statistically significant outcomes for whole-mouth plaque reduction, assessed using the Rustogi Modified Navy Plaque Index (P < .01), and gingivitis, assessed by using number of bleeding sites (P < .001), but not for the modified gingival index (P > .05) or gingival bleeding index (P > .05).
PRACTICAL IMPLICATIONS
There is some evidence to suggest that OR powered toothbrushes might remove more plaque and reduce the number of bleedings sites better than other powered toothbrushes, specifically, sonic action toothbrushes.

Meta-Analysis Review
OBJECTIVE
Previous studies demonstrated a dose-dependent efficacy of sodium bicarbonate when added to dentifrices for the mechanical control of dental biofilm. The present systematic review and meta-analysis aimed to evaluate the efficacy of a 67% sodium bicarbonate-based toothpaste for gingival health parameters improvement in subjects with gingivitis.
MATERIALS AND METHODS
An electronic search on MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL), was performed using a combination of keywords, followed by a hand search on pertinent Journals. Randomized controlled trials (RCTs) and prospective comparative studies in English language were included. There was no publication date and language restriction. The data regarding gingival, bleeding, and plaque index were extracted from the selected studies. Included studies underwent risk-of-bias assessment. When at least 3 studies reporting the same outcome were found, a meta-analysis was undertaken, to estimate the combined effect. Trial Sequential Analysis (TSA) was also performed to evaluate the power of the meta-analysis for primary outcomes.
RESULTS
The search strategy yielded 83 articles. After screening, 7 RCTs were included. Three were at high risk, one at moderate risk, and 3 at low risk-of-bias. Significant improvement of gingival index, bleeding index, and plaque index was observed in patients using 67% sodium bicarbonate toothpaste as compared with control subjects. TSA showed sufficient power for modified Gingival index and bleeding scores.
CONCLUSIONS
The clinical use of 67% sodium bicarbonate toothpaste can improve periodontal health in patients with gingivitis.
