Abstract This case report describes successful long-term conservative management of a cervical root fracture and a complicated crown fracture of the maxillary central incisors in a 12-year-old patient. A mineral trioxide aggregate partial pulpotomy was performed on the maxillary right central incisor, while the maxillary left central incisor was splinted to the neighbouring lateral incisor using an acid-etch technique. Both teeth remained asymptomatic throughout the 3.5 years of a review period, with the cervical root fracture having mostly healed with the formation of a calcified tissue between the fragments. Two different treatment methods were used for two different injuries that resulted in pulp preservation in both cases. This in turn has provided for normal root development to occur while also allowing for preservation of bone.
摘要 本病例报告描述了一名12岁患者的颈椎根骨折和上颌中切牙复杂冠折的成功长期保守治疗。对上颌右中切牙进行了三氧化矿物凝聚体部分牙髓切断术,而上颌左中切牙则采用酸蚀技术固定于相邻侧切牙。在3.5年的复查期内,两颗牙齿均无症状,颈椎根骨折大部分已愈合,骨折碎片间形成了钙化组织。针对两种不同的损伤采用了两种不同的治疗方法,均实现了牙髓保存。这反过来又促进了牙根的正常发育,同时也保留了牙槽骨。
