Root fractures occur more frequently in fully erupted permanent teeth with closed apices in which the completely formed root is solidly supported in the bone and periodontium. The consequences can be complex because of combined damage to the pulp, dentine, cementum, bone, and periodontium. Management of horizontal root fractures and lateral luxation depends on several factors, with the result that various clinical modalities have been suggested. This case report describes the treatment and 10-year follow-up of two maxillary central incisors, one with horizontal root fracture and the other with lateral luxation, treated with mineral trioxide aggregate and root canal treatment, respectively.
根折更常发生于完全萌出、根尖闭合的恒牙,此时完全形成的牙根在牙槽骨和牙周组织中得到牢固的支持。由于牙髓、牙本质、牙骨质、骨和牙周组织的联合损伤,后果可能很复杂。水平根折和侧向脱位的处理取决于多个因素,因此提出了各种临床方法。本病例报告描述了用三氧化矿物聚合体和根管治疗分别治疗上颌中切牙的一例水平根折和一例侧向脱位的治疗和 10 年随访。
