The respondents were divided into three groups: Group 1 (eating only), Group 2 (eating and drinking), and Group 3 (eating, drinking, and gargling). Primary data were obtained from intraoral examination carried out by Debris Index (DI) with three-score category. The examination was only conducted in several tooth: posterior tooth (fully erupted tooth) and anterior tooth (upper and lower central incisors).

Statistical analysis was carried out using analysis of variance correlation test and using the Statistical Package for the Social Sciences (SPSS) software, version17. Results: Dental and oral hygiene status group is homogeneous (P = 0.484). A significant difference was observed between variables, such as eating and drinking with gargling group (P = 0.4250), the eating and drinking group (P = 0.2250), and the control group (P = 1.4833). Conclusion: Students who regularly drink water, especially with gargling habit, have a better oral hygiene than those who do not drink regularly.
