摘　　要：目的：探讨牙根未发育完全的根尖周炎应用MTA行根尖诱导成形术的临床疗效。方法：将9～16岁病人的98个牙根未发育完全的牙髓炎或尖周炎患牙纳入研究，随机分为2组，分别应用MTA和氢氧化钙行根尖诱导成形术，观察两组根尖孔关闭和根尖硬组织形成的量。结果：MTA组中92％根尖孔关闭，有钙化屏障形成，对照组中52％根尖孔关闭，两组差异显著，有统计学意义（P〈0．05）。结论：MTA应用于根尖诱导成形术是一种有前途的治疗方法，但应掌握好适应证。AIM：To compare mineral trioxide aggregate （MTA） with calcium hydroxide when they are used as apexification material in human teeth. METHODS ： Ninety eight teeth with pulpitis and/or apicitis were collected in patients between 9 and 16 years of age, and then they were randomly divided into two groups. One group was treated with MTA and the other group was treated with calcium hydroxide. RESULTS ： The rate of successful apex closure in the group using MTA on apexification was 92%, compared to 52% in the group using calcium hydroxide with statistics significance（ P 〈 0.05）. The pulp survival rate and dentinal bridge thickness were both significantly higher and thicker in the group using MTA. CONCLUSION： MTA approach for treating apexification was appropriate, effective and acceptable. It is a treatment with great potential and should be mastered.
