Oral health is a condition where teeth are free from plaque and food debris. Debris is a soft deposit consisting of food debris that sticks to the teeth. Pineapples have a high water and fiber content, which can clean some of the food debris that sticks to the dentin. This study was conducted using a quasi-experimental method with a pretest-posttest group design. The number of samples used was 47 people using the Slovin formula calculation based on the inclusion criteria. The data obtained were tabulated and analyzed using the Wilcoxon Test. The results of this study showed that the average before chewing pineapple was 1.4 and after chewing pineapple was 0.7, so the difference in the reduction obtained was 0.7. Based on the analysis using the Wilcoxon test, the p value was obtained = 0.000 (> 0.05). This means that chewing pineapple has an effect on reducing debris.
