Horizontal root fractures are uncommon, mainly occurring on the cervical and middle third of the root of permanent upper incisors. The diagnosis is essentially radiographic and requires different healing patterns, depending on some pre- and postinjury factors. The aim of this article was to report the clinical management and different healing types in three cases of horizontal root fractures on permanent dentition. In case 1, the pulp tissue was vital and no treatment was necessary. In case 2, a root canal treatment of the cervical fragment was necessary and in case 3, pulpal necrosis was verified and an apical surgery was performed.
水平根折并不常见，主要发生在恒牙上颌切牙根的颈部和中1/3处。诊断主要依靠影像学检查，根据损伤前后的一些因素，其愈合方式有所不同。本文旨在报告3例恒牙列水平根折的临床处理及不同的愈合类型。病例1中，牙髓组织活力正常，无需治疗。病例2中，需要对颈部断端进行根管治疗，病例3中，证实存在牙髓坏死，遂进行了根尖手术。
