Group 1 was chewing 100 grams of Fuji apples as the control group and group 2 was chewing 100 grams of Manalagi apples as the tested group. Results: The result from Paired Sample T-test shows that there was a significant difference of mean plaque index before and after chewing Fuji apples and Manalagi apples (p<0,05). The result from Independent Sample T-test shows that there was a significant difference of mean plaque index value between the group who was chewing Manalagi apples and group who was chewing Fuji apples (p<0,05). Conclusion: The conclusion of this study is that both of chewing Fuji apples and Manalagi apples are effective in reducing plaque accumulation, where chewing Manalagi apples shows higher efficacy in reducing plaque accumulation compared with chewing Fuji apples.
