Prevalence and Pattern of Taurodontism in an Indian Population: A Retrospective Radiographic Study

Abstract

Objective: This study was undertaken to assess the prevalence and pattern of taurodontism in an Indian Population.Materials and methods: In this retrospective descriptive study, panoramic radiographs of 542 patients were evaluated by two maxillofacial radiologists for the presence of taurodontism which is defined as the teeth having apically displaced pulp chamber and lacking the conventional constriction at the cementoenamel junction. A detailed medical and family history was recorded for all the subjects to determine the presence of any adjuvant developmental disorders or genetic disorders and any related syndrome.Results: Taurodont teeth were found in 32 patients with a person prevalence of 5.9% of which 15 (46.87%) were seen in males and 17 (53.12%) in females. In these 542 patients comprising of 7396 premolar and molars 52 teeth were seen with taurodontism with a teeth prevalence of 0.70%. Out of 52 teeth, the mandibular second molar teeth were most commonly effected (38.46%) followed by maxillary second molars (23.07%). Hypotaurodontism was the most common type (80.76%) followed by mesotaurodontism (11.53%) and the least common type was hypertaurodontism (7.69%).Conclusion: Taurodont teeth were found in 32 patients with a person prevalence of 5.9% and in 52 teeth were seen with taurodontism with a teeth prevalence of 0.70%.
