摘要

Periodontal disease is a major disease of the oral cavity with a high prevalence, especially in a number of developing countries. Analyze the relationship of fluorine concentration in drinking water with gingivitis periodontal disorder (Case study in Subdistrict of Tempe, Sengkang City, Wajo District). The type and design of the research is explorative / cross-sectional research. Selection of research subjects was conducted by cluster sampling method first to determine the sample population of the sample to be sampled in Tempe Subdistrict. Data analysis was done by univariate, bivariate and advance analysis (ROC to determine cut off risk of fluorine concentration and Layer analysis to determine the magnitude of interaction variable) using the value of α 5%. The fluorine concentration was set at 0.020 through ROC calculations. Different fluorine concentration results shown in the analyzes performed on cooking water consumption showed a p value of 0.067, which means consumption of high fluorine concentrations evenly distributed across all sources of cooked water. The condition of gingivitis is relatively different based on age classification with most patients in stratum age＞ 40 years. However, a total significant relationship was found between fluorine concentration and gingivitis incidence (p = 0.04). Statistical analysis also showed a positive relationship between the OHIS condition of respondents and the incidence of gingivitis indicated by index gingivitis data. Interaction of severe OHI-S condition variables with high fluorine concentrations resulted in severe gingivitis of 43.1%. In high and medium fluorine stratum concentrations, the effect of OHIS is significant on gingivitis. Comparison of the interaction of two risk factors versus one risk factor shows comparison. There was a correlation between fluorine concentration and gingivitis, found an interaction between fluorine concentration with OHI-S to gingivitis effect and also found Cut off Point for fluor of 0.02 ppm.
