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]对外伤露髓年轻恒牙进行活髓切断术治疗的疗效。方法选取外伤冠折露髓的年轻恒牙61颗进行活髓切断术,随机分为2组。MTA组32颗,采用MTA盖髓,Ca(OH)2组29颗,采用Ca(OH)2盖髓。术后1、3、6、12、24个月复诊观察疗效。结果 MTA组成功29颗,失败3颗。Ca(OH)2组成功25颗,失败4颗,两组之间结果差异无统计学意义。结论 MTA是一种有效的活髓切断药物。Objective To compare mineral trioxide aggregate（MTA）with calcium hydroxide（Ca（OH）2） as a vital pulpotomy agent in traumatized immature permanent teeth.Methods Sixty one selected teeth were randomly assigned to control group（（Ca（OH）2 pulpotomy were performed） and experimental group（MTA pulpotomy were performed） respectively.Patients were recalled for clinical evaluations after 1、3、6、12、24 months.Results There was no statistically significant difference between the success rate of teeth treated with Ca（OH）2（86.2%） in comparison to those treated with MTA（90.6%）.Conclusion Both MTA and Ca（OH）2 are effective pulpotomy agent for traumatized immature permanent teeth.
