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.
A 34-year-old male patient's cone beam computed tomography (CBCT) images were investigated.
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.
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.
额外尖和牛牙样牙本质都是病因复杂的牙齿异常。它们在非综合征患者中的联合出现较为罕见，需要特殊的牙科考量。本病例报告旨在呈现这种情况并讨论其临床意义。
对一名34岁男性患者的锥形束计算机断层扫描（CBCT）图像进行了研究。
在47号牙上观察到10个尖和一个锥形牙髓腔。使用Mimics 21.0和Geomagic 21.0软件对变形牙进行三维（3D）重建。此外，根据CBCT分析，16、17、26和27号牙被归类为低牛牙样牙本质。
一颗牙齿或一名患者同时出现额外尖和牛牙样牙本质的情况很少见。临床医生应能够识别这些异常并提供适当的管理和治疗策略。
