The aim of this study was to compare the clinical and radiographical success of mineral trioxide aggregate (MTA) and gutta-percha/AH-Plus used as a root canal filling material in primary second molars without successors. A total of 16 patients (9 girls, 7 boys) aged 6-13 years (mean: 10.5) were selected and randomly distributed into the treatment groups. Children were recalled for clinical and radiographic examination at 6, 12, 18, 24 and 36 months. Differences in treatment outcomes were analysed using chi-squared and Fisher's exact tests. Clinically, there was no significant difference in the success rates between the groups at the end of a 3-year follow-up period (MTA: 100%; Gutta-percha/AH-Plus: 70%) (P > 0.05). However, radiographically, there was a significant difference between the groups (MTA: 80%; gutta-percha/AH-Plus: 30%) (P < 0.05). The present study showed that MTA can be recommended for use in root canal treatment of primary molars without successors based on better radiographic success.
本研究的目的是比较无机三氧化物聚合体（MTA）与牙胶/AH Plus作为无继承恒牙的乳磨牙根管充填材料时的临床和影像学成功率。共选取了16例年龄在6至13岁（平均10.5岁）的患者（9名女孩，7名男孩），并随机分配到各治疗组。在6、12、18、24和36个月时对儿童进行临床和影像学检查。使用卡方检验和Fisher精确检验分析治疗结果的差异。临床上，在3年随访期结束时，两组的成功率无显著差异（MTA：100%；牙胶/AH Plus：70%）（P>0.05）。然而，在影像学上，两组之间存在显著差异（MTA：80%；牙胶/AH Plus：30%）（P<0.05）。本研究表明，基于更好的影像学成功率，MTA可推荐用于无继承恒牙的乳磨牙根管治疗。
