Traumatic injuries to the primary dentition are quite common. When primary teeth are subjected to trauma, force transmission and/or invasion of the underlying tooth germs lying in close proximity can result in a variety of disturbances in the permanent successors. Few of these disturbances include hypoplasia, dilaceration, or alteration in the eruption sequence and pattern. Dilaceration is defined as an angulation or sharp bend or curve in the linear relationship of the crown of a tooth to its root. A rare case of maxillary left central incisor having crown dilaceration and Vertucci's type II canal configuration with symptomatic periapical periodontitis is reported. Cone beam computed tomography was used for better understanding of the anomaly and complicated root canal morphology. The tooth was successfully managed by nonsurgical root canal therapy and restoration with resin composite to restore esthetics.
乳牙列的创伤性损伤相当常见。当乳牙受到创伤时，力的传递和/或紧邻的下方牙胚的侵入可导致恒牙后继牙出现各种紊乱。这些紊乱中很少见的包括发育不全、牙根弯曲或萌出顺序及模式的改变。牙根弯曲被定义为牙齿冠部与其根部的线性关系中出现的成角、急剧弯曲或曲线。本文报告了一例罕见的上颌左中切牙，其牙冠牙根弯曲且具有韦尔图奇II型根管形态，并伴有症状性根尖周炎。使用锥形束计算机断层扫描以更好地了解该异常情况和复杂的根管形态。通过非手术根管治疗和用树脂复合材料修复以恢复美观，该牙齿得到了成功处理。
