Abstract
Objectives: Green tea contains have antimicrobial, anticariogenic and therapeutic effects on several diseases. The goal of this research to determine the effect of gargling the green tea solution on salivary pH on teenage students population. This research is a Quasy experiment with a pre-post test randomized single blind control trial design.
Methods: Interventions include gargling green tea solution and measuring the pH saliva before and after intervention. The sample consisted of 60 subjects, divided into 3 groups consist of 20 respondents. Saliva was measured by a Hanna digital pH meter. Statistical analysis using Kruskal Wallis and Wilcoxon test. Significance is indicated by the value of p <0.05 with a confidence level of 95%.
Results: It showed that the data were not normally distributed (p <0.05). There was a significant difference between salivary pH before and after gargling green tea solution (p <0.05). Based on the Kruskal Wallis test, there was a significant difference between the control group and gargling with green tea solution group.
