The purpose of this study was to determine the prevalence of developmental dental anomalies and fluorosis in small cohort of Indian school children & teenagers.
Method
A total of 473 school children and teenagers (250 female & 223 male) of 6 - 17 years were examined clinically for developmental anomalies of teeth such as peg lateral, supernumerary teeth (mesiodens), and talon's cusp. Children were also examined for dental fluorosis.
Result
On examination 1.47% of the sample population, had at least one developmental dental anomaly. Prevalence of Peg lateral, Mesiodens, and Talon's cusp was 0.63%, 0.63% and 0.21% respectively while 87.9% showed fluorosis induced enamel hypoplasia.
Conclusions
the most common dental anomalies was Peg lateral and Mesiodens. The present study also emphasizes the need for de-fluoridation of water in the region, because of high incidence of enamel hypoplasia induced by fluorosis in the study group. Other developmental dental anomalies also differed in prevalence from previous reports, pointing to a possible ethnic variation.
