Abstract：
Taurodontism is a rare dental anomaly defined by a change in tooth shape due to Hertwig\'s epithelial sheath not folding inward at the right horizontal level. It has a larger pulp chamber and a pulpal floor that is shifted apically, and the cementoenamel junction (CEJ) is not constricted. This condition is more frequently observed in permanent teeth than in primary teeth and can occur in a bilateral or unilateral manner, affecting any quadrant or group of teeth. This brief case report discusses a 14-year-old female patient who presented with complaints of decayed teeth in the lower right and left posterior regions of the jaw. Radiographic examination revealed the presence of non-syndromic taurodontism in both the deciduous teeth and their permanent successors. Dental management included oral prophylaxis, application of pit and fissure sealants, indirect pulp capping, and restoration with glass ionomer cement for the affected teeth.
摘要：
Taurodontism是一种罕见的牙齿异常，其定义是由于Hertwig的上皮鞘在右水平处未向内折叠而导致的牙齿形状变化。它有一个更大的纸浆室和一个顶部移动的牙髓地板，牙釉质交界处（CEJ）没有收缩。这种情况在恒牙中比在乳牙中更常见，并且可以双侧或单侧方式发生。影响任何象限或牙齿组。这份简短的病例报告讨论了一名14岁的女性患者，该患者在下颌的右下部和左后部区域出现了腐烂的牙齿。放射学检查显示，乳牙及其永久性后继者中都存在非综合征性taurodonis。牙科管理包括口腔预防，凹坑和裂缝密封剂的应用，间接盖浆,并用玻璃离聚物水泥修复受影响的牙齿。
