Objectives: Green tea is a popular health drink routinely consumed by many people. In the past, various studies have demonstrated the beneficial effect of green tea extracts on periodontal diseases, but very few studies have correlated the daily dietary oral intake of green tea to the periodontal status of patients.

The subjects were divided into three groups using block randomization method depending on the type of therapy received, viz., scaling and root planing alone, scaling and root planing along with green tea intake, and green tea alone. The clinical parameters were recorded at baseline, 3 and 6 months. Results: The results of the study demonstrated the positive and statistically significant (P Clinical Relevance to Interdisciplinary Dentistry Green tea is a popular drink with beneficial effect on oral mucosa. It has been shown to have anti-cancer properties. Green tea has beneficial effect on periodontal diseases as well as bone resorption.
