The samples of this study were the students of MA PGAI Padang. 30 students were divided randomly into two groups, a control group and a test group. The test group were given sunflower seed oil, and control group were given aquadest . Dental plaque score was measured with PHP index before and after intervention. The data analyzed by computer program with independent sample t-test and its significancy accepted if p<0,05. The results showed the significant differences of plaque index decrease after intervention, 0,66 for the control group and 1,26 for the test group. It can be conclude that gargling with sunflower seed oil can decrease the plaque index.]]>
