Dens invaginatus is a malformation affecting mainly the superior lateral incisors. It is defined as an infolding of the crown hard tissues, including the enamel and dentin, and can extend up to the root apex. Root canal treatment of this abnormality is considered difficult due to the complex anatomy presented by these teeth. This case series presents nonsurgical endodontic treatment in two cases of dens invaginatus (type II and III) in maxillary lateral incisors. This nonsurgical or conventional endodontic treatment results in healing of the periapical lesions associated with both cases, with no need for extra intervention e.g. surgical or invasive management. The manual instrumentation associated with sodium hypochlorite and calcium hydroxide were able to completely heal the lesions. Radiographic exams were carried out to control and asses the healing. Nonsurgical treatment was successful in both cases with adequate repair after a 6-year follow-up with radiographic and tomographic assessments.
牙内陷是一种主要影响上颌侧切牙的畸形。它被定义为牙冠硬组织（包括釉质和牙本质）的内陷，并且可延伸至根尖。由于这些牙齿呈现出复杂的解剖结构，对这种异常情况进行根管治疗被认为是困难的。本病例系列介绍了对上颌侧切牙的两例牙内陷（II型和III型）进行的非手术根管治疗。这种非手术或传统的根管治疗使两例相关的根尖周病变均愈合，无需额外干预，例如手术或侵入性处理。与次氯酸钠和氢氧化钙相关的手动器械操作能够使病变完全愈合。进行了影像学检查以控制和评估愈合情况。经过6年的影像学和断层扫描评估随访，两例非手术治疗均成功且修复良好。
