目的观察无机三氧化物聚合体(MTA)糊剂、Vitapex糊剂和氢氧化钙(CH)糊剂三种不同根充材料对年轻恒牙根尖诱导形成术的临床疗效.方法将224患者共计257颗牙根未完全发育完成的年轻恒牙分为A组(71颗)、B组(68颗)和C组(65颗),分别用MTA糊剂、Vitapex糊剂和CH糊剂进行根尖诱导成形术,术后随访3年并比较临床疗效.结果 MTA组有效65颗,有效率91.55％; Vitapex组有效61颗,有效率89.70％; CH组有效50颗,有效率76.92％.Vitapex 组与CH组间比较差异有统计学意义(P＜0.05),MTA组与CH组间比较差异有统计学意义(P＜0.05),但MTA组与Vitapex组之间比较差异无统计学意义(P＞0.05).结论与CH糊剂比较,MTA糊剂和Vitapex糊剂为更理想的临床根尖诱导材料.

Objective To study the effectiveness of mineral trioxide aggregate (MTA),Vitapex paste and calcium hydroxide(CH) paste in apexification for young permanent teeth.Methods 257 younger permanent teeth with underdeveloped apex and necrotic pulp from 224 cases were randomly selected.The average age was (9.3 ± 1.5) years old.The teeth were randomly assigned to three groups,71 teeth in group A, 68 teeth in group B and 65 teeth in group C.After root canals were prepared and sterilized, the apexification was assigned with MTA paste used in group A,Vitapex paste used in group B and CH paste used in group C.All the teeth were observed for three years.Results In group A,65 teeth were effective and the effective rate was 91.55％.In group B,61 teeth were effective and the effective rate was 89.70％.In group C,50 teeth were effective and the effective rate was 76.92％.There Was significant difference between Vitapex paste and CH paste (P＜ 0.05).And there was significant difference between MTA paste and CH paste (P ＜ 0.05).There was no significant difference in MTA paste and Vitapex paste (P ＞ 0.05).Conclusion MTA paste and Vitapex paste were more ideal materials than HA paste for apexification in young permanent teeth.
