title: Prevalence of periodontal disease in endemically flourosed areas of Davangere Taluk, India.
abstract: Success of fluoride in combating dental caries led to study of fluoride on periodontal disease, but studies are less reported in literature and results are varied in nature. To address this issue, the study was conducted to assess severity of periodontal disease among (n = 283) 36-45 years old adults residing in area of different concentration of fluoride in drinking water. The villages selected were having fluoride concentration in their drinking water are Shamnur (0.5 PPMF), Kundawada (1.1 ppmF) and Halebathi (3.17 ppm). Ion Selective Electrode Method (OrionUSA) estimated fluoride in drinking water. Community Periodontal Index (WHO, 1997) and Plaque Index (Silness and Loe, 1967) was used to assess periodontal status. There was consistent decrease in mean plaque score from 1.45+ _0.024 at 0.51 ppm, 1.21+ _0.009 at 1.1 ppm, and 1.12+ _0.08 at 3.17 ppm fluoride area. This difference was significant statistically (P < 0.001). As the fluoride concentration in drinking water increased there was decrease in severity of prevalence of periodontitis. This difference in observation was significant statistically (P < 0.05). There were no effects of fluoride on calculus, since little variability was found in three different fluoride areas. Thus it was concluded from the study results that the increase in fluoride concentration decreased the plaque accumulation. decreased the shallow and deep pockets. Hence lower prevalence and severity of periodontal disease.
