摘要/Abstract

摘要：

牙内陷是由牙发育时期成釉器过度卷叠或局部过度增殖，深入到牙乳头中而导致的牙齿形态异常，因其复杂的解剖结构，给常规的牙髓治疗带来困难和挑战。牙中牙的牙髓治疗为牙内陷最复杂的一种情况，本文报道1例上颌侧切牙年轻恒牙牙中牙伴根尖周炎的牙髓血运重建治疗的病例，结合锥形束CT的辅助诊断，对其治疗及预后进行评估。随访2年，牙根继续发育，根尖周炎症消失。本病例为年轻恒牙牙中牙的牙髓病及根尖周病提供了新的治疗策略。

Abstract:

Dens invaginatus (DI) is a developmental anomaly as a result of a deepening or invagination of the enamel organ into the dental papilla during tooth development. In addition, DI is a malformation with varying anatomical features, which poses numerous challenges to treatment. Endodontic treatment of dens in dente is one of the most complica-ted cases of DI. Herein, an immature lateral incisor that employed regenerative endodontic treatment was presented. The mentioned tooth was diagnosed with DI, pulp necrosis, and chronic apical periodontitis. Hence, a favorable prognosis has been shown by a 2-year review with cone beam computed tomography. The tooth was functional with normal periodontal parameters and exhibited a normal response to the electric pulp sensibility test. Thus, regenerative endodontic treatment can also be recommended to endodontists for teeth with DI.

Key words: dens in dente, regenerative endodontic theatment, cone beam computed tomography
