摘要
目的:观察深龋露髓的患牙应用无机三氧化聚合物(mineral trioxide aggregate,MTA)行直接盖髓术的治疗效果。方法:对18-40岁患者50颗深龋去腐露髓和意外露髓患牙,随机均分为两组,分别用MTA和氢氧化钙行直接盖髓术。2-3年后行临床评价,观察MTA直接盖髓术疗效。结果:应用MTA行患牙直接盖髓术,2-3年后修复牙本质桥形成,牙髓活力保持,其成功率与对照组差异无统计学意义(P〉0.05)。结论:MTA作为直接盖髓剂是一种满意材料。
Objective:To observe the effect of mineral trioxide aggregate(MTA) as direct pulp capping agent in human teeth.Methods:Fifty teeth in patients between 18 and 40 years of age were randomly divided into two groups.The exposed pulps were capped with MTA or calcium hydroxide,respectively.All the cases were followed up for 2 and 3 years.Results:The pulp vitality and dentinal bridge thickness were both higher and thicker in the MTA group than in the calcium hydroxide group,but there was no significant statistical difference in the success rate between the two groups(P〉0.05).Conclusions:MTA may be an ideal material as direct pulp capping agent in human teeth.
