This study is a retrospective analysis of the outcome of initial nonsurgical root canal treatment of teeth with open apices, obturated with mineral trioxide aggregate when no apical barrier existed. One hundred sixteen patients from a single private endodontic office were treated between 1999 and 2006. Treatments on 144 teeth were completed either in one (92/144) or two visits with an interim calcium hydroxide interappointment medication (52/144). Fifty-four percent (78/144) of the teeth were available for recall (60.3% one visit and 39.7% two visits). The maximum time to recall was 4.87 years. The mean time to recall was 19.4 months. Of the cases recalled for period of 1 year or longer, 93.5% of teeth treated in 1 visit healed, and 90.5% of teeth treated in 2 visits healed.
本研究是一项回顾性分析，针对根尖开放牙齿的初始非手术根管治疗结果，在不存在根尖屏障时使用三氧化矿物凝聚体进行充填。1999年至2006年间，来自一家私人牙髓病诊所的116名患者接受了治疗。144颗牙齿的治疗在一次就诊（92/144）或两次就诊并在两次就诊期间使用氢氧化钙临时药物（52/144）完成。54%（78/144）的牙齿可供回访（一次就诊的占60.3%，两次就诊的占39.7%）。回访的最长时间为4.87年。回访的平均时间为19.4个月。在回访1年或更长时间的病例中，一次就诊治疗的牙齿93.5%愈合，两次就诊治疗的牙齿90.5%愈合。
