Dental caries and Periodontal diseases are the two most common diseases of the mankind. Dental plaque is the common etiological factor for both of these disease conditions. apart from mechanical plaque control, chemical plaque control through the use of mouth rinse may aid as a valuable adjunct in controlling  and the pathogenic microbes in dental plaque which cause these diseases. many chemical plaque controlling agents were in use, but with significant side effects like staining of teeth, alteration of taste perception, dental calculus build up, allergic reactions in the oral cavity, development of white patches etc. thus a natural and culturally acceptable, cost-effective chemical agents which has less or no side effects is desirable in this context. red ginseng is one such product which has proven systemic benefits and has been used for various systemic diseases . this intervention study therefore aims to measure the benefits of red ginseng extract containing mouth rinse against gingivitis and gingival bleeding. chlorhexidine gluconate and sodium fluoride  mouth rinses served as positive controls. 90 patients are to be recruited with 30 patients in each of the 3 groups. 1st group was given the red ginseng extract containing mouth rinse, 2nd group was given Chlorhexidine gluconate mouth rinse and 3rd group was given Sodium Fluoride mouth rinse. informed consent will be obtained from the patients before recruiting them for the study. outcome variables measured were Index values of Plaque Index and gingival index at baseline, 2 weeks, 4 weeks and at 6 weeks. the test mouth rinse, red ginseng extract containing mouth rinse is expected to have beneficial effects in reducing the disease process and thereby show a reduction in the index values as compared tto the baseline value.
