Root-end filling is important for the clinical outcome of endodontic microsurgery. Our previous study showed that combined application of iRoot BP Plus Root Repair Material (BP-RRM) and iRoot SP Injectable Root Canal Sealer (SP-RCS) in root-end filling exhibited better apical sealing as compared to the application of BP-RRM alone. The aim of this randomized controlled clinical trial was to evaluate the effect of the combined use of BP-RRM and SP-RCS on the prognosis of teeth with refractory periapical diseases after endodontic microsurgery.
240 teeth with refractory periapical diseases scheduled for endodontic microsurgery were randomly divided into BP-RRM/SP-RCS group (n = 120) and BP-RRM group (n = 120). The patients were followed up at 3 months, 6 months, and 12 months after endodontic microsurgery. Pre- and post-operative clinical and radiographic examinations were performed to evaluate the treatment outcome. The 1-year success rate of endodontic microsurgery in BP-RRM/SP-RCS and BP-RRM groups was compared by Chi-square test. Factors that might impact the prognosis were further analyzed using Chi-square test or Fisher's exact test.
A total of 221 teeth completed the 12-month follow-up. The 1-year success rates of the BP-RRM/SP-RCS and BP-RRM groups were 94.5% (104/110) and 92.8% (103/111), respectively. The combined use of BP-RRM and SP-RCS achieved a clinical outcome comparable to BP-RRM alone (P = 0.784). Tooth type (P = 0.002), through-and-through/apico-marginal lesion (P = 0.049), periodontal status (P < 0.0001), and Kim's lesion classification (P < 0.0001) were critical factors associated with the 1-year success of endodontic microsurgery.
The combined use of BP-RRM and SP-RCS is a practicable method for root-end filling in endodontic microsurgery with a satisfactory 1-year clinical outcome.
The combined application of BP-RRM and SP-RCS in EMS is an effective root-end filling method with a satisfactory 1-year clinical outcome.

根尖封闭对于根管显微手术的临床效果至关重要。我们之前的研究表明，与单独应用 iRoot BP Plus 根管修复材料（BP-RRM）相比，iRoot SP 可注射根管封闭剂（SP-RCS）联合应用于根尖封闭可获得更好的根尖封闭效果。本随机对照临床试验旨在评估 BP-RRM 和 SP-RCS 联合应用对根管显微手术后难治性根尖病变牙齿预后的影响。
将 240 颗难治性根尖病变的患牙随机分为 BP-RRM/SP-RCS 组（n=120）和 BP-RRM 组（n=120）。在根管显微手术后的 3、6 和 12 个月进行随访。进行术前和术后临床及影像学检查以评估治疗效果。采用卡方检验比较 BP-RRM/SP-RCS 组和 BP-RRM 组根管显微手术后 1 年的成功率。采用卡方检验或 Fisher 确切概率法进一步分析可能影响预后的因素。
共有 221 颗牙完成了 12 个月的随访。BP-RRM/SP-RCS 组和 BP-RRM 组的 1 年成功率分别为 94.5%（104/110）和 92.8%（103/111）。BP-RRM 和 SP-RCS 的联合应用可获得与 BP-RRM 单独应用相当的临床效果（P=0.784）。牙型（P=0.002）、贯穿性/根尖边缘病变（P=0.049）、牙周状况（P<0.0001）和 Kim 病变分类（P<0.0001）是与根管显微手术 1 年成功率相关的关键因素。
BP-RRM 和 SP-RCS 的联合应用是根管显微手术中一种可行的根尖封闭方法，具有满意的 1 年临床效果。
BP-RRM 和 SP-RCS 在 EMS 中的联合应用是一种有效的根尖封闭方法，具有满意的 1 年临床效果。
