Prevalence of taurodontism in patients of PUCRS Dentistry College

Abstract

Taurodontism is an anomaly of development more common in molars, which is the enlargement of the pulp chamber and decreased root size. The distance between the furcation to the cementenamel junction is greater than the cervical-occlusal distance. Since the crowns are not abnormal, the diagnosis is radiographic. The study aimed to evaluate the prevalence of taurodontism patients of PUCRS Dentistry College, set the teeth and dentition most affected, analyze the gender most prevalent, and sort according to Shifman and Chanannel20. The examinations were observed using homogeneous light negatoscope and pre-selected. After have been scanned and transferred to the Image Tool software. The examiners were two students trained, supervised by Professor of Radiology. The data were analyzed using descriptive statistics with the SPSS software version 10.0. For the comparison between the two measurements taken, was used t-student test for paired data. The average age was 21.9 years with a standard deviation of 9.8 years. The prevalence in patients was 5.3%. The hipotaurodontism had the largest number of cases (73.6%). The distribution according to gender was not statistically significant. The tooth most prevalent was the second upper molar (47.2%) and permanent teeth was most affected. According to t-student test, there are not statistically significant differences between the examinators. The prevalence of taurodontism in the sample was consistent with the works in the literature. The hipotaurodontism was more prevalent among the three classifications. The most affected tooth was the second permanent molars. There are no significant differences between genders.
