Dens invaginatus is a rare developmental anomaly characterized by an infolding of the enamel organ within the crown or root of a tooth, and it is an example of a dental anomaly that has a higher incidence in patients with CL/P. If undiagnosed, dens invaginatus can lead to severe, acute pain and pulpal necrosis since it can permit direct entry of bacteria into the dental pulp. Treatment of dens invaginatus includes prophylactic sealant or composite restoration, endodontic therapy if pulpal involvement has already occurred, or extraction if aberrant tooth morphology precludes endodontic therapy. Few studies report on the incidence of dens invaginatus in patients with CL/P. The purpose of this article is to describe 4 cases of dens invaginatus in patients with CL/P which were encountered in a cleft-craniofacial orthodontic clinic. Each case describes dens invaginatus in a maxillary lateral incisor, and treatments ranged from sealant application to endodontic therapy to extraction. These cases highlight the importance of awareness of this dental anomaly among cleft team providers to facilitate early diagnosis in patients with CL/P.
牙内陷是一种罕见的牙齿发育畸形，其特征为牙冠或牙根内的釉质器内陷。牙内陷是一种牙齿畸形，在唇腭裂患者中的发病率更高。如果未被诊断，牙内陷可导致严重的急性疼痛和牙髓坏死，因为它可使细菌直接进入牙髓。牙内陷的治疗包括预防性封闭剂或复合树脂修复，如果已经发生牙髓受累，则进行根管治疗，如果异常的牙齿形态妨碍根管治疗，则进行拔牙。很少有研究报告唇腭裂患者的牙内陷发生率。本文的目的是描述在腭裂颅面正畸诊所中遇到的 4 例唇腭裂患者的牙内陷。每个病例均描述了上颌侧切牙的牙内陷，治疗方法从封闭剂应用到根管治疗到拔牙不等。这些病例强调了腭裂团队提供者对这种牙齿异常的认识的重要性，以便在唇腭裂患者中早期诊断。
