1The 940th Hospital of Joint Logistic Support Force of the Chinese People's Liberation Army, Lanzhou, 730050, People's Republic of China.
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.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
