Root fractures are defined as those that involve cement, dentin and pulp, comprising from 0.5 to 7% of injuries in permanent dentition. Diagnosis is made through clinical and radiographic exams, the latter frequently being limited by the position of the fracture. Treatment varies according to the displacement and vitality of the fragments. The authors present a clinical case of recurrent trauma of tooth 21 causing a horizontal root fracture in the middle third. After several attempts at endodontic treatment, the option was to remove the apical fragment by surgery. The postoperative period of 4 years shows very satisfactory results with regard to wound repair and tooth mobility, or implantation of the coronal segment.
根折是指涉及牙骨质、牙本质和牙髓的骨折,占恒牙列损伤的0.5%至7%。通过临床和影像学检查进行诊断,后者常常受骨折位置的限制。治疗方法根据碎片的移位情况和活力而有所不同。作者介绍了一例21号牙反复创伤导致牙根中部水平折裂的临床病例。经过多次根管治疗尝试后,选择通过手术去除根尖碎片。4年的术后观察显示,在伤口修复、牙齿松动度或冠段植入方面取得了非常满意的结果。
