Abstract

Abstract: Tea is a kind of beverage which is consumed by many people. Tea has a wide range of beneficial properties to our health. Green tea catechins has an active component that can reduce the formation of Streptococcus mutans as a component of the formation of dental plaque. This study aimed to determine the effectiveness of rinsing with water steeping green tea in reducing plaque accumulation. This was an experimental study using pretest and posttest design. This study was conducted in Dental Study Program Sam Ratulangi University. There were a total of 50 samples. The results showed that the average value of the initial index plaque of the samples was 4.829; of day 1 was 4.140; of day 2 was 3.674; of day 3 was 3.200; of day 4 was 2.524; of day 5 was 1.895; of day 6 was 1.477; and of day 7 was 1.078. The Wilcoxon test showed a p value <0.05, which meant that there was a significant difference between plaque index before rinsing water steeping with green tea and plaque index after the rinse water steeping green tea. Conclusion: Rinsing with green tea was effective in decreasing dental plaque index.
