Abstract:
Background: Bleeding gums are one of the common complaints to visit a dentist. Mechanical removal of plaque alone is not sufficient for the reduction of gingival inflammation associated with plaque. Mouthwashes are supplemented to it as a homecare product. The objective of this study is to evaluate the efficacy of 0.2% sodium hypochlorite mouthwash on plaque and gingival inflammation and to assess the clinical parameters of gingivitis patients from baseline to 21 days with the use of 0.2% sodium hypochlorite and 0.2% chlorhexidine mouthwashes.
Materials and Methods: This clinical trial study included 60 patients with gingival inflammation evaluated using clinical parameters such as bleeding on probing index, plaque index, and gingival index at baseline and 21 days. Group A patients were given Hi Wash mouthwash and Group B 0.2% chlorhexidine mouthwash with 30 patients in each group. Results: The scores for clinical parameters were significantly reduced after 21 days in Group A and Group B patients, and there was a reduction in plaque‑associated gingival inflammation without scaling and root planning.
Conclusions: 0.2% sodium hypochlorite mouthwash is as effective as 0.2% chlorhexidine for the treatment of gingivitis as it is an adjunct to mechanical plaque removal in terms of safety, less side effects, less staining and can be used as a routine mouthwash.

Background: Previous studies have demonstrated the inhibitory effect of hydrogen-rich water on biofilm formation. However, hydrogen-rich electrolyzed water (HEW) has not been evaluated as mouthwash, despite being economical, convenient, and biologically safe. We assessed the antibiofilm effects of HEW on Streptococcus mutans and its potential as a mouthwash.
Methods: The effect of HEW on S. mutans growth was assessed by measuring bacterial colony-forming units, and biofilm formation capacity was examined by crystal violet staining after culturing on a polystyrene plate. The effect of HEW on biofilm formation-related gene expression in S. mutans was assessed by real-time polymerase chain reaction. Finally, the effect of HEW on salivary S. mutans and plaque maturation was evaluated in 24 participants; after gargling with HEW twice daily, the salivary S. mutans count was quantified using a Caries Risk Test bacteria kit (Ivoclar Vivadent AG), and plaque maturation was compared using quantitative light-induced fluorescence imaging.
Results: Exposure to HEW resulted in no significant changes in S. mutans growth but a significant reduction in biofilm formation in vitro (p<0.001). Furthermore, the gene expression of glucosyltransferases (gtfB, gtfC) was significantly lower than that in the control group treated with tap water (p<0.05, p<0.01). S. mutans counts and plaque maturation were significantly lower in participants who gargled with HEW than in those who gargled with tap water (p<0.01).
Conclusion: Our data suggest that oral rinsing with HEW exerts antibiofilm effects on S. mutans, indicating that it can be used as a mouthwash to treat dental biofilm-dependent diseases.

在医学上，皮肤病是有关皮肤的疾病，是严重影响人民健康的常见病、多发病之一，如麻风、疥疮、真菌病、皮肤细菌感染等。皮肤病是皮肤（包括毛发和甲）受到内外因素的影响后，其形态、结构和功能均发生变化，产生病理过程，并相应的产生各种临床先后表现。皮肤病的发病率很高，多比较轻，常不影响健康，但少数较重甚至可以危及生命。
