Effectiveness of green tea on plaque-induced gingivitis – A clinical trial

Background: Plant extracts have been widely used in the topical and oral applications for disease treatment. Green tea (Camellia sinensis) has been reported to be useful for the prevention of periodontal disease and maintenance of oral health. Aim and Objectives: We aim to assess the efficacy of Green tea mouthwash on plaque-induced gingivitis as the most common form of periodontal disease. Methodology: A single-blinded placebo-controlled clinical study will be conducted with two groups as case and control, each consisting of 40 female patients with the age group of 14–16 years. Both the groups will be equally distributed to receive either 5 ml of Green tea 5%two times/day or normal saline with the same dosage. Results: Gingival index (Sillness and Loe), plaque index (Loe and Sillness) were recorded at baseline and five consecutive weeks and there was a decrease in score. Conclusion: Green tea mouthwash may be a safe and feasible adjunctive treatment for inflammatory periodontal diseases. Therefore this study was conducted for evaluating the effect of green tea.
