中文摘要
本文报告1例右侧下颌第一磨牙原发性牙根纵裂的发现与诊治过程。通过临床检查、多普勒血流仪及影像学等辅助检查,发现该患牙牙髓电测试有反应,激光多普勒测试有血运。本病例采用显微根尖手术方法以及纳米生物活性材料进行治疗,术后随访1年效果良好,实现了对该患牙折裂部分的去除及感染控制,以活髓状态保存患牙。
英文摘要
This case presents vertical root fracture with vital pulp in mandibular right first molar. Examinations of the history, clinical tests, laser Doppler flowmetry, and radiographs revealed that the tooth showed positive response to electric pulp testing and was normal compared with the healthy control tooth. This study aimed to use a novel vital preserving surgical technique (microapical surgery and nanometer bioactive materials) to make an effective therapeutic decision for the vital tooth with vertical root fracture.
