Taurodontism is a morpho-anatomic variation in the shape of teeth that chiefly affects molars in primary as well as secondary dentition. Aim: The aim was to assess the prevalence of taurodontism in premolars and molars by studying the orthopantomogram (OPGs) of the patients visiting a dental teaching hospital in Pune, India. Materials and Methods: A retrospective, cross-sectional study was carried out, wherein the panoramic radiographs of 525 randomly selected patients were evaluated for taurodontism. A detailed medical and family history record of the patients was also obtained. Radiographic analysis for taurodontism was carried out in premolars and molars. Prevalence of taurodontism was assessed, and a comparison among male and female prevalence was done using the z-test. Results: Prevalence of taurodontism was 11.8%. Taurodontism was exhibited in 12.5% females and 9.7% males. Unilateral taurodontism was seen in 24 (4.57%) and bilateral taurodontism in 38 (7.23%) of the 525 OPGs. Mandibular second molars were the teeth most commonly affected by taurodontism. Conclusion: There was a high prevalence of taurodontism in patients visiting the dental teaching institute. Orthopantamogram can be used effectively to detect taurodontism. The findings of this study revealed that premolars may also be affected with taurodontism
