The purpose of this retrospective study was to evaluate the clinical outcomes of ProRoot mineral trioxide aggregate used as an artificial apical barrier in teeth with immature apices. Twenty teeth from 19 patients were included in this study. A healed diagnosis was based on periapical index scores of 1 or 2 and no clinical signs or symptoms at recall examinations. Eighty-five percent (17/20) of these teeth were healed, and improvements in periapical index scores at recall appointments were shown to be statistically significant (P < .001, Wilcoxon signed-rank test). Chi-square test indicated that age, gender, primary treatment versus retreatment, presence of preoperative lesion, and differences in recall times did not significantly influence healing outcome. Overall, these results indicated that the mineral trioxide aggregate apical barrier technique is a successful method for obturating teeth with immature apices.
这项回顾性研究的目的是评估使用ProRoot三氧化矿物凝聚体作为未成熟根尖牙齿的人工根尖屏障的临床效果。本研究纳入了19名患者的20颗牙齿。愈合诊断基于根尖指数评分为1或2，且在复查时无临床体征或症状。这些牙齿中有85%（17/20）愈合，复查时根尖指数评分的改善具有统计学意义（P <.001，Wilcoxon符号秩检验）。卡方检验表明，年龄、性别、初次治疗与再次治疗、术前病变的存在以及复查时间的差异对愈合结果没有显著影响。总体而言，这些结果表明三氧化矿物凝聚体根尖屏障技术是一种封闭未成熟根尖牙齿的成功方法。
