| Abstract | ||
| The purpose of the study was to determine the prevalence of dental fluorosis in a group of school students lived in area with high and low natural fluoride contained drinking water in Ninevah Governorate. The study was conducted among (1724) school's students aged (11-16) years from randomly selected schools (primary and intermediate) in two provinces in Ninevah Governorate. Eight hundred and thirteen students who had lived since birth in high natural fluoride level area (Sinjar province) (2.05-2.22 ppm) and (911) students lived continuously from birth in low natural fluoride level area in their drinking water (Talkaif province) (0.11-0.19 ppm). Dean index has been used to assess the dental fluorosis. The results show that the prevalence of dental fluorosis in Sinjar province is (97.3%) within individual and (62.9%) within teeth, ranging from very mild to mild form of dental fluorosis, with no significant sex difference, but the percentage of severity has been found to be increasing with age, while the prevalence of dental fluorosis in Talkaif province was (5.5%) within individual and (1.2%) within teeth, with no significant sex difference. The community fluorosis indices for Sinjar and Talkaif provinces are (1.7 and 0.1) respectively. This difference is due to the difference in level of natural fluoride in both provinces drinking water supplies. | ||
