Considering the importance of epidemiological studies in identifying diseases and designing necessary prevention plans, the present study was fulfilled to assess dental fluorosis in 8-27 years old population of Dehloran, Mousian and Dasht Abbas areas during 2006.
Materials & Methods: Throughout this analytical descriptive study, 573 cases of 8-27 years old population were selected using a cluster sampling method and examined in respect of different fluorosis rates (Dean index: normal, questionable, very mild, mild, moderate and severe) and DMFT rate (WHO index) using observations and questionnaires. The gained data were analyzed using t - student and chi – square tests.
Findings: Generally commenting, 86.6% of the studied populations showed degrees of fluorosis and only 13.4% of them proved free from the disease. Dasht Abbas district showed the highest prevalence of fluorosis.
The maximum rate of fluoride in Dehloran town's water was 0.67,while it was 0.78 in Dasht Abbas meanwhile, the rate in Mousian district was 0.37 ppm. Totally, 82.9% of the samples with 12 and less records of residential experience and 91.6% with more than 12 years of residential experience indicated fluorosis. The uninfected people showed a mean DMFT of 2.84, while the fluorosis–free cases showed a mean DMFT of 3.38 without any significant differences.
Discussion & Conclusion: The research came to the conclusion that totally 86.6% of 8-27 years old population of Dehloran, Mousian and Dasht Abbas residential places indicated degrees of infection with dental fluorosis in 2006, a rate considered to bo too high for such a population. |
