目的：比较 M TA 及 Vitapex 两种根尖诱导药物的短期疗效。方法：选择患者50人，共62颗前磨牙，随机分为实验组和对照组，其中实验组为32颗，使用 M TA 进行根尖诱导治疗，对照组为30颗，使用 Vitapex 糊剂进行根尖诱导治疗。分别术后3、6、12个月复查，根据临床检查和 X 片结果评价其疗效。采用卡方检验比较两组有效率、成功率差异。结果：术后3、6、12个月复查，M TA 有效率分别为93．8％、96．9％、96．9％，Vitapex 有效率分别为93．3％、90.0％、86．7％，二者差异无统计学意义。术后3、6、12个月复查，M TA 成功率分别为28．1％、62．5％、68．8％，Vi‐tapex 成功率分别为20．0％、30．0％、36．7％，6个月和12个月 M TA 的成功率明显高于 Vitapex 。结论：应用 M TA 作为根尖诱导药物，就诊时间少且远程效果好。

Objective :To compare the short‐term clinical efficacy in apexification of M TA and Vitapex .Methods :50 ca‐ses of outpatient ,a total of 62 infected premolar with central cusp which under root forming stage were randomly divid‐ed into M TA group(32 cases) and Vitapex group(30cases) .After 3 months ,6 months and 12 months ,clinical effect and X‐ray results were evaluated .Effective rate and successful rate were assessed with chi‐square statistics .Results :There was no statistically significant difference between two groups in effective rate after 3 months ,6 months and 12 months ,but successful rate showed statistically significant difference between two groups in effective rate after 6 months and 12 months .Conclusion :M TA is expected to have a shorter visiting time and better effect than Vitapex .
