Purpose: Pilocarpine as a salivation stimulant in pill form has mostly been used to relieve oral dryness for xerostomic patients but its use may often be limited due to variable side effects from systemic absorption. Therefore, the purpose of this study was to investigate the effects of pilocarpine mouthwash on salivation according to the variable concentration and duration for healthy volunteers. Related adverse effects and subjective assessment on its effects on salivation were also examined. Methods: This study was performed as placebo-controlled, double-blind, randomized clinical trial. Thirty healthy volunteers (male=23, mean age=22.2 years) were randomly allocated to 6 groups with the different concentration of pilocarpine mouthwash (placebo, 0.1%, 0.5%, 1.0%, 1.5%, and 2.0%). The whole experiment consisted of 3 sessions according to the duration of mouthwash, i.e., 1, 3, and 5 minutes with the mean wash-out period ${\geq}2$ days between the sessions. Unstimulated whole saliva was collected before and after gargling with a mouthwash. Results: Salivation of the higher concentration groups ${\geq}1%$ significantly increased than those of lower concentration group. The application period of mouthwash did not cause any changes of salivary flow rate at the higher concentrations ${\geq}1.0%$. The lower concentrations of 0.5% and 0.1% had no effects on salivation even after 5-minute mouthwash. There was no significant difference between blood pressure and pulse rate before and after use of mouthwash. Conclusions: From the results of the current study, pilocarpine mouthwash with at least 1.0% concentration more than a minute might be clinically effective in salivation without any serious side effects. Dose of mouthwash rather than duration seems to be a critical factor to salivation.

In this study, natural mouthwash was developed based on natural substances based on cinnamon and ginger, which are familiar to the public, to check the effectiveness of mouthwash and changes in microbial distribution. This study was conducted on 24 people who fully explained the purpose and method of the study and agreed to participate among those who visited D University from October 2021 to December 2021. The subject's oral cavity was examined and placed in three groups to have similar conditions, and after using mouthwash for a week, a survey, saliva test, breath measurement test, and PCR test were performed. As a result of the experiment, the amount of saliva after using natural mouthwash increased compared to the control group (P<0.05). In the comparison of bacteria, it was confirmed that Pg and Fn bacteria decreased after using natural mouthwash (Pg t=4.852, P=.002, Fn t=2.888, P=.023). Following this study, it is expected that research on the development and efficacy of natural mouthwash will be conducted through various clinical applications, which will be useful in real life and dental care institutions.

A novel glucanhydrolase(DXAMase) from a mutant of Lipomyces starkeyi(KSM 22) has been shown effective in hydrolysis of mutan, reduction of mutan formation by Streptococcus mutans and removal pre-formed sucrose-dependentadherent microbial film and DXAMase has been strongly bound to hydroxyapatitie. These in vitro properties of Lipomyces starkeyi DXAMase are desirable for its application as a dental plaque control agent. This study was performed to determine the adjunctive oral hygiene benefits and safety of dextranase(Lipomyces starkeyi KSM 22 DXAMase)-containing mouthwash when used alongside normal tooth-brushing. This 6-month clinical trial was placebo-controlled double-blind design evaluating 1U/ml dextranase mouthwash and 0.12% chlorhexidine mouthwash. A total 39 systemically healthy subjects, who had moderate levels of plaque and gingivitis were included. At baseline, 1, 3 and 6 months, subjects were scored for plaque accumulation(Turesky modification of Quingley-Hein's plaque index), gingivitis status($L\ddot{o}e$ and Silness gingival index), and tooth stain(Area and severity index system by Lang et al). Additionally, oral mucosal examinations were performed and subjects questioned for adverse symptoms. Two weeks after pre-experiment examinations and a professional prophylaxis, the subjects provided with allocated mousewash and instructed to use 20-ml volumes for 30s twice daily after toothbrushing. All the groups showed significant increase in plaque accumulation since 1 month of experiment. During 6 months' period, the Dextranase mouthwash group showed the least increase in plaque accumulation, compared to the Chlorhexidine mouthwash and placebo groups. As for gingival inflammation, all the groups showed significant increase during 6 months of experiment. The Experimental group(Dextranase mouthwash) also showed the least increase in gingival index score, compared to the Positive control(Chlorhexidine mouthwash)as well as the Negative control(placebo)groups. Whereas the tooth stain was increased significantly in the Positive control group, compared to the baseline score and the Negative controlgroup since 3 months of mouthrinsing. It was significantly increased after 6 months in the Experimental group, still less severe than the Positive control group. As for the oral side effect, the Experimental group showed less tongue accumulation, bad taste, compared to the Positive control group. From these results, mouthrinsing with Lipomyces starkeyi KSM 22 dextranase provided adjunctive benefits to toothbrushing, comparable to 0.12% chlorhexidine mouthwash in inhibition of plaque accumulation and gingival inflammation and local side effects were if anything less frequent and less intense than chlorhexidine, with long-term use of the mouthwash. All data had provided positive evidence for Lipomyces starkeyi KSM 22 dextranase as an antiplaque agent and suggested that further development of dextranase formulations for plaque control are warranted.

Purpose: Triphala is a combination of three medicinal plants, extensively used in Ayurveda since ancient times. Triphala mouthwash is used in the treatment of periodontal diseases because of its antimicrobial and antioxidant properties. The aim of this study is to compare the efficacy of triphala mouthwash with 0.2% chlorhexidine in hospitalized periodontal disease patients. Methods: In this double-blind, randomized, multicenter clinical trial, 120 patients were equally divided into three groups. Patients in group A were advised to rinse their mouths with 10 mL of distilled water, group B with 0.2% chlorhexidine, and group C with triphala mouthwash for 1 minute twice daily for two weeks. The plaque index (PI) and the gingival index (GI) were recorded on the first and the fifteenth day. Results: There was no significant difference when the efficacy of triphala was compared with 0.2% chlorhexidine in hospitalized patients with periodontal disease. However, a statistically significant difference was observed in PI and GI when both group B and group C were compared with group A and also within groups B and C, after 15 days (P<0.05). Conclusions: The triphala mouthwash (herbal) is an effective antiplaque agent like 0.2% chlorhexidine. It is significantly useful in reducing plaque accumulation and gingival inflammation, thereby controlling periodontal diseases in every patient. It is also cost effective, easily available, and well tolerable with no reported side effects.

Purpose : The purpose of this study was to compare changes of salivary flow rate, salivary buffering capacity, and S. mutans after using a mouthwash containing essential oil or probiotics widely used as oral lactic acid bacteria in the oral environment. Methods : Fifty-three healthy adults aged 20 years or older voluntarily participated in this study after they were informed of the purpose of this study. Subjects were divided into a group treated with probiotics (L. reuteri) and a group treated with mouthwash containing essential oil. To evaluate changes in the oral environment, salivary flow rate, salivary buffering capacity, and S. mutans test were performed at baseline and 4 weeks later. Unstimulated and stimulated salivary flow samples were collected for 5 minutes and results were recorded in ml per minute. Salivary buffering capacity was divided into scores of 1 (low), 2 (moderate) and 3 (high) according to the color of the strip. The amount of S. mutans was classified as scores of 0, 1, 2, and 3 according to the decision table. Data collected in this study were analyzed at the 95 % significance level using the SPSS Version 23.0 program. Results : Both the unstimulated salivary flow rate and the stimulated salivary flow rate increased statistically after the intervention compared to those before intervention in the probiotics group. However, there was no statistically significant difference between the probiotics group and the mouthwash group. Salivary buffering capacity and S. mutans results showed no statistically significant differences between the probiotics group and the mouthwash group either. The salivary buffering capacity and the salivary flow rate showed a positive correlation. Conclusion : To improve the oral environment, such as salivary flow rate and salivary buffering capacity, an optimal product can be selected in consideration of individual preference and cost-effectiveness.

The purpose of this study was to compare the staining ratio on the enamel surface following the use of chlorhexidine mouthwash and the chlorhexidine varnish application. Labial and lingual surfaces of maxillary and mandibular incisors of adults were selected to evaluate the staining ratio. The control group was consisted of 8 individuals, the experimental group 1 and 2 were consisted of 50 each. Prophylaxis with pumice was performed to remove the stain already established on the enamel surface of all groups. The group 1 was asked to use chlorhexidine mouthwash(Hexadent, chlorhexidine gluconate 1ml/100ml) for a minute twice a day. The chlorhexidine $varnish^{(R)}$($Chlorzoin^{(R)}$, consisted of solution 1(10% chlorhexidine acetate) and solution 2(polyurethane sealant)) was applied on the enamel surfaces of the group 2. After 4 weeks of experiment, intraoral photogragh of tooth surfaces were taken in order to record the stained area on the enamel of the control and the experimental groups. Outline of teeth and the stained area in the photographs was traced on the OHP film. Scanner and computer processor were used to calculate stained surface ratio.

Purpose: To evaluate the clinical and microbiological effects of the local use of egg yolk immunoglobulin against Porphyromonas gingivalis (anti-P.g. IgY) as an adjunct to scaling and root planing (SRP) in the treatment of moderate to severe chronic periodontitis. Methods: This was a randomized, placebo-controlled, double-blind trial involving 60 systematically healthy patients with moderate to severe chronic periodontitis. Subjects (n=20/group) were randomly assigned to receive SRP combined with subgingival irrigation of anti-P.g. IgY and anti-P.g. IgY mouthwash, subgingival irrigation of 0.2% chlorhexidine and 0.2% chlorhexidine mouthwash, or subgingival irrigation of placebo and placebo mouthwash for 4 weeks. Probing pocket depth, clinical attachment level, bleeding on probing, and the plaque index were evaluated at baseline and at 4 weeks. Subgingival plaque, gingival crevicular fluid, and saliva were simultaneously collected for microbiological analysis. Results: Our results showed that anti-P.g. IgY mouthwash was as effective as chlorhexidine at improving clinical parameters over a 4-week period. All the groups showed a significant reduction in levels of P.g. at 4 weeks. No significant difference was observed in the test group when compared to placebo regarding the reduction in the levels of P.g. Anti-P.g. IgY significantly suppressed the numbers of red complex bacteria (RCB) in subgingival plaque and saliva in comparison with placebo. No adverse effects were reported in any of the subjects. Conclusions: Within the limitations of the study, the present investigation showed that passive immunization with anti-P.g. IgY may prove to be effective in the treatment of chronic periodontitis due to its ability to improve clinical parameters and to reduce RCB. No significant differences were found between the anti-P.g. IgY and placebo groups in the reduction of P.g.
