摘要
目的观察三氧化矿物凝聚体(mineral trioxide aggregate,MTA)和氢氧化钙[Ca(OH)2]对根尖诱导成形术治疗的临床疗效。方法选取患根尖周炎的年轻恒牙53颗,分为2组进行根尖诱导成形术。MTA组(28颗)采用MTA行根尖诱导;Ca(OH)2组(25颗)采用Ca(OH)2行根尖诱导。分别于术后3个月、6个月、9个月、1年、1年半复诊拍摄X射线片并观察临床疗效。结果 MTA组成功27颗,失败1颗;Ca(OH)2组成功23颗,失败2颗,两组有效率比较差异无统计学意义。结论MTA是一种有效的根尖诱导成形药物,可在临床上广泛应用。
Objective To observe the clinical efficiency of mineral trioxide aggregate （ MTA ） and calcium hydroxide [ Ca （ OH） 2 ] in apexification for immature permanent teeth .Methods Fifty-three immature permanent teeth with apical paradentitis were randomly assigned to control group （25 teeth） treated with Ca（OH）2apexification and experimental group （28 teeth） treated with MTA apexification.Patients were recalled for clinical evaluations after 3,6,9,12 and 18months.Results There was no statistically signifi-cant difference in success rate between the two groups .Conclusion MTA is an effective apexification drug that can be widely used in clinical practice .
