Peatlands in Borneo is the second which the pH is 32% below normal that is 2-5, the pH of the acid contained in the peat water can trigger the acid environment of the oral cavity resulting in increased aerobic bacteria of the oral cavity. Most small communities of South Kalimantan who lives inland which is unreachable with clean water still use peat water for daily necessities. The purpose of this study was to determine the effect of peat water to the number of aerobic bacteria colonies of the oral cavity. This study used the quasi-experimental research design with pre-posttest control group design. The study sample consisted of 20 students of Faculty of Dentistry, Lambung Mangkurat University. The research used peat water after mouth rinsing with 10 ml of water and then the number of aerobic bacteria colonies which were present in bacterial growth media was counted. The result of this study showed that the result of paired t-test showed no significant differences between the groups before and after rinsing with  peat water (p = 0.001) (p <0.005). Based on the research we conclude that the peat water may cause an increasing in the number of colonies of aerobic bacteria of the oral cavity.
