The present report describes a case of a mid-root fracture in a maxillary central incisor of a 19-year-old patient. The fractured tooth was splinted with composite that was removed only 3 years later, as the patient did not appear for follow-up examinations. At this time, the radiographs revealed a normal periodontal ligament, rounding of the borders of the fragments and pulp obliteration of both fragments. Eight years later, the tooth was clinically normal and blurred calcification of the root canal was disclosed radiographically. After 13.5 years the patient complained of tooth mobility and radiographic examination revealed an advanced cervical root resorption. As no conservative approach was possible at this stage, the patient was referred to a prosthodontist for esthetic rehabilitation.
本报告描述了一名19岁患者上颌中切牙牙根中部骨折的病例。折断的牙齿用复合材料进行了夹板固定,仅在3年后拆除,因为患者未前来进行后续检查。此时,X线片显示牙周膜正常,断端边缘圆钝,两个断端均出现牙髓腔闭塞。8年后,该牙齿临床检查正常,X线片显示根管有模糊的钙化。13.5年后,患者主诉牙齿松动,X线检查显示有严重的牙根颈部吸收。由于在此阶段已无法采用保守治疗方法,遂将患者转介给修复科医生进行美学修复。
