摘要:

目的　观察带环修复固位力欠佳的乳磨牙根管治疗齿的临床疗效，探讨更佳修复方法，提高临床修复成功率。　方法　将经过根管治疗的120颗乳磨牙随机分成3组,分别使用FX玻璃离子，3MZ250树脂充填，树脂充填后带环修复3种方法修复，随访观察1年。比较各组治疗后3个月，6个月，12个月的治疗成功率。　结果　治疗3个月，6个月，12个月后随访。FX玻璃离子组成功率分别为90%， 80%， 55%；3MZ250组成功率分别为87.5%， 75%，57.5%；带环组成功率分别为100%， 85%，92.5%。FX玻璃离子组与3MZ250组修复的成功率差异无显著性意义(P>0.01)。FX玻璃离子组、3MZ250组与带环组修复的成功率差异有显著性意义(P<0.01)。　结论　带环修复根管治疗后的乳磨牙是一种简单易行，效果良好的修复方法。

Abstract:

[Abstract] Objective To observe and evaluate the clinical effects of using band restoration after primary molars root canal treatment in order to improve the success rate of clinical treatment. 　Methods 120 primary molars root canal treatments were selected and randomly divided into three groups. The primary molars were filled with FX glass ionomer cements (group 1), 3MZ250 light-cured composite resin (group 2) and band restoration after filling with 3MZ250 light-cured composite resin (group 3). All patients were followed up after 3 months, 6 months and 12 months. 　Results The success rate of group 1 was 90%， 80%， 55%,group 2 was 87.5%， 75%，57.5% and group 3 was 100%， 85%，92.5%.The first two groups showed no significant difference (P>0.01).But there was statistically significant difference between the first two groups and the three group (P<0.01). 　Conclusion Using band restoration after primary molars root canal treatment was a simple and good method for a successful clinical treatment.
