简介：本随机临床试验的目的是评估牙髓显微手术（EMS）后使用矿物三氧化物骨料（MTA）与EndoSequence根修复材料（RRM; Brasseler, Savannah， GA）作为根端填充材料的愈合情况。方法：将243颗持续性或复发性根尖牙炎患者随机分为MTA组和RRM组。随访时间分别为6个月、12个月和24个月，随访时间为临床和影像学检查，12个月后进行锥形束计算机断层扫描（CBOT）成像。结果：共对120颗牙进行评估，平均随访15个月。根尖周（PA）评估的总成功率为93.3%，CBCT评估的总成功率为85%。通过PA和CBCT成像评估，RRM组分别显示92%和84%的成功率。通过PA和CBCT成像评估，MTA组的成功率分别为94.7%和86%。两组间差异无统计学意义。显微手术分类、根管填充质量、根端填充材料深度和根断裂是显著的预后预测因素。结论：当RRM或MTA作为根端填充材料时，EMS是一种可预测的方法，在二维和三维影像学评估中都取得了成功的结果。
Introduction: The purpose of this randomized clinical trial was to evaluate healing after endodontic microsurgery (EMS) using mineral trioxide aggregate (MTA) versus EndoSequence root repair material (RRM; Brasseler, Savannah, GA) as root-end filling materials. Methods: Two hundred forty-three teeth with persistent or recurrent apical periodontitis were randomly assigned to either the MTA or RRM group. EMS was performed, and follow-up visits with clinical and radiographic investigation were scheduled at 6, 12, and 24 months with follow-up cone-beam computed tomographic (CBOT) imaging after 12 months. Results: One hundred twenty teeth with an average follow-up of 15 months were evaluated. The overall success rate was 93.3% for periapical (PA) evaluation and 85% for CBCT evaluation. The RRM group exhibited 92% and 84% success rates as assessed on PA and CBCT imaging, respectively. The MTA group exhibited 94.7% and 86% success rates as assessed on PA and CBCT imaging, respectively. No significant difference was observed between the 2 groups. Microsurgical classification, root canal filling quality, root-end filling material depth, and root fracture were found to be significant outcome predictors. Conclusions: EMS is a predictable procedure with successful outcome both 2-dimensional and 3-dimensional radiographic evaluation when RRM or MTA was used as the root-end filling material.
