目的探讨磨牙根纵裂的治疗以及修复方式对疗效的影响。方法对已明确诊断的56颗上颌第一磨牙根纵裂,拟保留的牙根完成根管治疗术,发生根纵裂的牙根进行截根术,待伤口愈合后再行全冠或联冠修复。结果术后两年随访52例,失访4例。2例病人未按照医嘱镶冠(其中1例冠折,1例食物嵌塞)。全冠修复24例,失败1例,成功率95.83%。联冠修复26例,失败1例,成功率96.15%。两者之间对比p>0.05,无统计学差异。结论对发生在上颌磨牙的根纵裂,对无病变的牙根进行完善的根管治疗,病变的牙根采用截根术,结合全冠或联冠修复,两年观察成功率较高。
Objective To investigate the effect of the treatment of molars root longitudinal cleft and the repair method on curative effect. Methods Root cleft of 56 maxillary first molars with definite diagnosis, root canal to be preserved and root canal with root cleft were truncated. The wounds were healed again with full crown or double crown. Results 52 cases were followed up for two years and 4 cases were lost to follow-up. Two patients did not follow the doctor’s instructions (one case of coronary artery disease, one case of food impaction). Full crown repair in 24 cases, failure in 1 case, the success rate of 95.83%. 26 cases were repaired by the crown, one case failed, the success rate was 96.15%. Between the two p> 0.05, no statistical difference. Conclusions Root canal rupture occurred in the maxillary molars, and the root canal treatment of non-diseased roots was performed. The root of the lesions was treated with root cutting, combined with crown or crown, and the success rate was high in two years.
