摘要

Purpose

Supernumerary cusps and taurodontism are both dental anomalies with complex etiology. Their combination in a non-syndromic patient is rare and requires special dental considerations.This case report is to present this occurrence and discuss its clinical significance.

Methods

A 34-year-old male patient’s cone beam computed tomography (CBCT) images were investigated.

Results

Ten cusps and a pyramidal pulp chamber were observed on tooth 47. Mimics 21.0 and Geomagic 21.0 software were used for three-dimensional (3D) reconstruction of the deformed tooth. Moreover, teeth 16, 17, 26 and 27 were classified as hypotaurodontism based on CBCT analysis.

Conclusion

Simultaneous occurrence of supernumerary cusps and taurodontism in one tooth or patient is rare. Clinicians should be able to identify these anomalies and provide appropriate management and treatment strategy.
