Abstract

ABSTRACT
Objective: The aim of the present study was to determine the frequency and sexual difference of taurodontism in a sample of orthodontic patient population with respect to sexes, jaws and dental localization using the criteria of Shifman and Chanannel. Material and Methods: A retrospective study was performed using periapical and panoramic radiographs of 1.324 patients ranging in age from 12 to 20 years. All data (age, sex and systemic disease or syndrome) were obtained from the files of the patients. Molar teeth-except third molars-were included in this study. Statistical analysis of the data was performed using the computer program SPSS and the frequency distribution for taurodontism was also calculated. Pearson chi-square test was used to compare the frequency of taurodontism between male and female subjects. Results: Taurodontism was observed in 4.5% of the subjects and 1.9% of the molar teeth examined. It was almost equally distributed between females and males. Taurodontism was distributed more frequently in maxilla than mandible. The maxillary second molar was the most frequently affected tooth. Conclusion: Taurodontism is found to be uncommon in an orthodontic patient population, however, further larger scale studies are required to assess its frequency in the general population to compare it with the other ethnic groups.
