[PMID: 31869441 DOI: 10.1111/jcpe.13244] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Revised: 12/17/2019] [Accepted: 12/18/2019] [Indexed: 11/28/2022]
Abstract
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; I2 = 96.2%), bleeding (%) (n = 26, WMD=-14.62%; 95% CI [-18.01%; -11.23%]; p < .001; I2 = 95.1%), plaque index (n = 93, SMD = -1.017; 95% CI [-1.194; -0.840]; p < .001; I2 = 95.3%) and plaque (%) (n = 23; WMD = -18.20%; 95% CI [-24.00%; -12.50%]; p < .001; I2 = 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.

Abstract
AIM The aim of this network meta-analysis (NMA) was to compare the efficacy of different oral hygiene products for chemical biofilm control, in 6-month home-use, randomized clinical trials (RCTs), in terms of changes in gingival index (GI). MATERIAL AND METHODS Six-month RCTs assessing GI were identified and screened for inclusion. Relevant information was extracted, and quality and potential risk of bias were estimated. Mean differences between baseline and end were calculated to obtain standardized mean differences (SMDs). NMA protocols were applied to assess direct and indirect comparisons among products using Löe & Silness GI, modified GI and gingival severity index. RESULTS Fifty-three papers were included, 19 studies for mouth rinses, 32 for dentifrices, comprising data from 5,775 and 2,682 subjects, respectively. When ranking treatments, similar results were observed for all tested dentifrices, with the lowest effect observed for sanguinarine and baking soda. For mouth rinses, essential oils, triclosan-copolymer, chlorhexidine (at concentrations ≥ 0.10%) and cetylpyridinium chloride (>0.05%) demonstrated the greatest effect. CONCLUSION Although NMA revealed significant differences when comparing placebo versus some active agents, when comparing among active agents, no differences were found for dentifrices, while mouth rinses containing essential oils showed the greatest effect on GI scores.

Abstract
AIM The aim of this systematic review and network meta-analysis (NMA) was to compare the efficacy of different anti-plaque chemical agents, in 6-month, home-use, randomized clinical trials (RCTs), in terms of plaque index (PlI) changes. MATERIAL AND METHODS RCTs assessing PlI were identified, screened, and evaluated for inclusion. Relevant information was extracted, and quality and risk of bias were assessed. Mean differences between baseline-end were calculated to obtain weighted mean differences and 95% confidence intervals. NMA protocols were applied to assess direct and indirect comparisons among products using Turesky PlI. RESULTS Eighty-three papers were included: 49 examined dentifrices, 32 mouthrinses and 2 both. The NMA analysed 51 studies including data from 4242 and 4180 subjects for dentifrices and mouthrinses respectively. For dentifrices, triclosan-copolymer and chlorhexidine showed the greatest effect, with significant differences when compared with stannous fluoride. For mouthrinses, essential oils and chlorhexidine showed the greatest effect, with significant differences when compared with delmopinol, alexidine and cetylpyridinium chloride. CONCLUSION Within the limitations of this study (including the severe imbalance in the amount of evidence), dentifrices containing triclosan-copolymer or chlorhexidine and mouthrinses containing essential oils or chlorhexidine showed the greatest effect on PlI scores as assessed with NMA.

Abstract
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.

Abstract
Dental plaque is a biofilm that forms naturally on the surfaces of exposed teeth and other areas of the oral cavity. It is the primary etiological factor for the most frequently occurring oral diseases, such as dental caries and periodontal diseases. Specific, nonspecific, and ecologic plaque hypothesis explains the causation of dental and associated diseases. Adequate control of biofilm accumulation on teeth has been the cornerstone of prevention of periodontitis and dental caries. Mechanical plaque control is the mainstay for prevention of oral diseases, but it requires patient cooperation and motivation; therefore, chemical plaque control agents act as useful adjuvants for achieving the desired results. Hence, it is imperative for the clinicians to update their knowledge in chemical antiplaque agents and other developments for the effective management of plaque biofilm-associated diseases. This article explores the critical analysis of various chemical plaque control strategies and the current trends in the control and prevention of dental plaque biofilm.

Abstract
INTRODUCTION Since the discovery that periodontal diseases are caused by microbial plaque the interest of many scientists has been focused on oral antiseptics. There are very few mouthrinses with oral antiseptic effect originally designed in our country. One of these is Ozosept solution. OBJECTIVE This study evaluated the effect of Ozosept solution (phenol compound) on the oral hygiene and gingival inflammation, in comparison with Hibidex DAP solution (chlorhexidine digluconate). METHODS Two groups, each of 21 persons, which did not significantly differ concerning Silness-Löe plaque index (PI) and Löe-Sillnes gingival index (GI), used one of the studied oral antiseptic for a 15-day period. Oral hygiene was maintained by subjects' habitual home methods, and no technique of professionally advised brushing was performed during the experimental period. RESULTS At the end of the study, PI and GI scores were lowered to a statistically high significance in both groups of participants in comparison to the indexes at the beginning of the study. At the end of the study, PI and GI scores did not significantly differ between the two analyzed groups. No side effects, which were recorded in the Hibidex DAP group (tooth and filling staining 9.5% and 4.74% respectively, transitory tongue numbness 28.6% and reduced taste sensation 14.3%), were registered in the group of subjects using Ozosept solution. CONCLUSION It is concluded that Ozosept solution is effective in the control of dental plaque--biofilm accumulation and gingival inflammation, and produces no side effects related to chlorhexidine digluconate usage.

Abstract
Based on scientific proof, only few mouthrinse solutions can be recommended. However, it is impossible to construct an extended table that would provide precise recommendations or advices for mouthrinse utilisation related to any possible discomfort or diseases. Only reliable information on the drugs available against periodontal disease can be offered to the therapist. By evaluation of her or his individual experiences, she or he has to judge all the armamentarium she or he possesses to react in the best possible way in each specific situation.

Abstract
BACKGROUND Although mechanical plaque control methods have the potential to maintain adequate levels of oral hygiene, clinical experience and population-based studies demonstrate that such methods are not being employed sufficiently by large numbers of the population. The need for additional help in controlling bacterial plaque provides the rationale for patients' using antimicrobial mouthrinses as adjuncts to their mechanical oral hygiene regimens. TYPES OF STUDIES REVIEWED The author presents an overview of the types of studies used to support the effectiveness of antiplaque and antigingivitis mouthrinses, ranging from laboratory studies to six-month clinical trials. He discusses plaque as an example of a biofilm and the implications of recent research on the nature of biofilms with respect to the nature of the evidence that can be used to demonstrate clinical effectiveness. CONCLUSIONS The safety and clinical effectiveness of antiplaque and antigingivitis antimicrobial mouthrinses are best determined using prospective, randomized clinical trials conducted in accordance with ADA guidelines. CLINICAL IMPLICATIONS The adjunctive use of antimicrobial mouthrinses can provide significant benefits to patients who cannot maintain adequate levels of plaque and gingivitis control through mechanical methods alone. Dentists should recommend products that have proven clinical activity as demonstrated using generally accepted safety and effectiveness criteria.

Abstract
The efficacy of the fluoride-chlorhexidine association in the prevention of gingivitis and caries has been advocated for a number of years. The objective of the association of these therapeutic agents is a synergistic action. The aim of the present study was to determine the substantivity of chlorhexidine associated or not to sodium fluoride at different intervals of time, in vitro. Bovine enamel surfaces were treated with 0.12% chlorhexidine gluconate (Periogard--Colgate) or 0.05% sodium fluoride with 0.12% chlorhexidine (Duplak--Dentsply) solutions for one minute. Fragments were placed in distilled water and samples were collected at intervals of 5, 30 and 360 minutes and analyzed by spectrophotometry in the visible ultraviolet region. Substantivity was evaluated by the measurement of chlorhexidine desorption from the treated slabs. The mean values obtained were statistically analyzed by Student's t-test. The results showed that the concentration of chlorhexidine decreased when it was used in association with sodium fluoride. The difference between the groups was statistically significant (p < 0.05). These in vitro results suggest that the association between sodium fluoride and chlorhexidine in the studied concentrations appears to have no beneficial effect because of the decrease in the substantivity of chlorhexidine.

Abstract
There is a preponderance of evidence in the literature that periodontal and other oral diseases, such as caries, can be treated and controlled by thorough mechanical plaque removal by the patient, the use of antimicrobial agents and antibiotics when necessary, and participation with the therapist in a well monitored, long-range program of supportive periodontal therapy. Recent evidence suggests that the control and prevention of oral disease, especially periodontitis, is especially important for patients with various systemic conditions that can be impacted by oral infections. It is far better for patients and therapists to practice primary and even secondary prevention with effective plaque control and regular, consistent supportive periodontal therapy, than having to rely on tertiary prevention for disease that has progressed to a level that requires costly treatment, is time-consuming and carries a greater risk of morbidity.

Abstract
OBJECTIVES A meta-analysis technique was used to pool data from studies to assess the effectiveness of the pre-brushing rinse PLAX on existing plaque and gingivitis. METHODS Studies were identified using MEDLINE and other sources, and grouped according to whether PLAX was used in short- or long-term treatment. The quality of trials was assessed by 2 independent readers. The DerSimonian and Laird random effects model was used. Meta-analyses were performed according to duration and type of PLAX treatment. In "1-day" studies, the effect of PLAX after rinsing and after rinsing and brushing was evaluated, whereas in longitudinal studies, this was done at several follow-up times. RESULTS A total of 19 studies were included and mean quality scores ranged from 0.13 to 0.60, for the study protocol from 0.18 to 0.70 and for data analysis and presentation from 0.05 to 0.53. In "1-day" studies, PLAX significantly reduced plaque after rinsing (difference=0.143; 95% CI=0.02-0.27;p=0.022), whereas no significant reduction was observed in post-brushing measures. In "longitudinal" studies, plaque was significantly reduced at 1-2 (difference=0.168; 95% CI=0.09-0.24; p<0.0001), 3-4 (difference=0.179; 95% CI=0.01-0.35; p=0.043), 12 (difference=0.288; 95% CI=0.21-0.37; p<0.0001) and 24 (difference=0.377; 95% CI=0.19-0.57; p=0.0001) weeks. The meta-analysis that evaluated gingivitis showed a significant reduction in inflammation with PLAX treatment at 12 (difference=0.209; 95% CI=0.17-0.25; p<0.0001) and 24 (difference=0.257; 95% CI=0.22-0.29; p<0.0001) weeks follow-up. CONCLUSIONS Although PLAX use appears to offer some benefit in plaque and gingivitis reduction, the clinical magnitude of the difference and the benefit on oral health are likely to be small.

Abstract
This review considers the main agents which have been used as antibacterial agents in mouthwashes and other vehicles to inhibit the growth of supragingival plaque. The agents discussed are bisguanide antiseptics, quaternary ammonium compounds, phenolic antiseptics, hexetidine, povidone iodine, triclosan, delmopinol, salifluor, metal ions, sanguinarine, propolis and oxygenating agents. The plaque inhibitory, anti-plaque and anti-gingivitis properties of these agents are considered along with their substantivity, safety and possible clinical usefulness. Clinical trials of these agents that have been published are also reported. The possible clinical uses of antiseptic mouthwashes are finally considered along with some advice about assessing manufacturers claims. Throughout this review the terms plaque inhibitory, anti-plaque and anti-gingivitis have been used according to the clarification of terminology suggested by the European Federation of Periodontology at its second workshop. This defines a plaque inhibitory effect as one reducing plaque to levels insufficient to prevent the development of gingivitis; an anti-plaque effect as one which produces a prolonged and profound reduction in plaque sufficient to prevent the development of gingivitis; and anti-gingivitis as an anti-inflammatory effect on the gingival health not necessarily mediated through an effect on plaque.

Abstract
The removal of plaque by toothbrushing with toothpaste is the most common form of plaque control in the developed world. However, the use of chemical adjuncts such as mouthrinses is increasing. In practice mouthrinses and toothpaste are used together, however, in many clinical trials, employed to assess mouthrinse activity, toothpaste use is suspended. This fails to measure the effect of chemical interactions which are known to occur between toothpaste ingredients and mouthrinses. The objective of this trial was to develop a methodology which would assess the adjunctive chemical plaque inhibitory action of mouthrinses, when used with toothpaste but without the indeterminate variable of toothbrushing. The study was a single blind, randomised, 7-way crossover design, based on a variation of a 4 day plaque regrowth model. The 2 x daily rinsing regimens produced increasing plaque scores in the following order: (1) water/chlorhexidine, (2) chlorhexidine/water, (3) chlorhexidine/toothpaste slurry, (4) toothpaste slurry/chlorhexidine, (5) water/toothpaste slurry, (6) toothpaste slurry/water, (7) water/water. Chlorhexidine and water or chlorhexidine and toothpaste slurry combinations produced significantly lower plaque scores than water alone. Slurry and water combinations resulted in less plaque than water alone, but differences were not significant. Toothpaste slurry and chlorhexidine produced significantly increased plaque scores compared to chlorhexidine and water. The study suggests that, outside the Hawthorne effect, chlorhexidine rinses would be less effective in reducing plaque when used with toothpaste than when used alone. The methodology could be employed as a screening tool for the evaluation of mouthrinses expected to be used as adjuncts to normal oral hygiene methods. The same could be used to optimise oral hygiene regimens which include the use of mouthrinses.

The present clinical trial was performed to evaluate short-term effects of a triclosan-containing dentifrice/gel combination on soft tissue healing, when applied supra-/sub-gingivally at periodontal sites treated with scaling and root planing. 16 subjects with moderate periodontitis participated in a 2x 2-week, split-mouth designed clinical trial. 2 combinations of gel/dentifrice (the test combination containing triclosan) were used. 2 pairs of contralateral sites with probing pocket depth (PPD) > or 5 mm, and which bled on probing (BoP +) were selected in each patient as experimental units. A baseline examination included assessments of PPD, BoP, gingival index scores, plaque index scores, and the composition of the subgingival microbiota (dark-field microscopy). The assigned quadrant was anaesthetized and the teeth exposed to meticulous scaling and root planing. Immediately after the completion of mechanical therapy, either the test or control gel was applied subgingivally at the experimental sites. The volunteer was instructed to brush his/her teeth with an assigned dentifrice and to apply the gel (via a custom-made stent) supra-gingivally 2x daily for the following 2 weeks. He/she was recalled on day 7 for a second professional subgingival gel application. Re-examinations were carried out on days 2, 7 and 14 after treatment. 1-week wash-out periods separated the 2 experimental periods. The mean PPD reductions (between days 0 and 14) were 1.8 mm and 1.9 mm for the test and control gel/dentifrice sites. The reduction in BoP and gingival index scores was significantly greater during the test than during the control regimen. No significant differences were observed between the 2 regimens regarding plaque scores and composition of the subgingival microbiota. The findings from the present investigation demonstrated that triclosan, applied both sub- and supra-gingivally reduced soft tissue inflammation following scaling and root planing.

Abstract
There are a large number of mouthrinse products available to the general public for use as adjuncts to oral hygiene. Many have not been evaluated and relatively few comparisons of products have been made. This study compared 4 mouthrinse products containing cetylpyridinium chloride (CPC), chlorhexidine, C31G, or triclosan with saline rinse included as a placebo control. Twenty dentate volunteers took part in this 4-day plaque regrowth study which had a single blind, randomized cross-over design balanced for residual effects. On day 1 of each study period, volunteers were rendered plaque free by a professional prophylaxis, suspended normal oral hygiene measures, and rinsed twice daily for 1 minute with 15 mL of the allocated rinse. On day 5, subjects were scored for disclosed plaque by plaque index and plaque area. By both measures the order of decreasing product efficacy was chlorhexidine, CPC and triclosan, C31G, and saline. All the differences in favor of the chlorhexidine product were highly significant as were those in favor of the other rinses compared to saline. It is concluded that the findings of this study reflect the actual chemical benefits of the products divorced from the indeterminate variable of toothbrushing.

Abstract
Inhibition of the development of dental plaque remains one of the primary aims of periodontal care. Many patients, however, are unable to master completely the mechanical methods of plaque control and for this reason, considerable research efforts have been directed towards the development and use of chemical agents to inhibit the growth of plaque. This first of two articles, therefore, examines the pharmacological properties and efficacy of commercially available antiplaque agents. We have also summarized the findings of some of the major clinical trials that have provided the scientific basis for the introduction of these agents for the management of gingival inflammation.
