Abstract：
BACKGROUND: This study aimed to investigate the effect of unintentional AH Plus sealer extrusion on the outcome of nonsurgical root canal treatment and retreatment in teeth with apical periodontitis (AP) compared to teeth with AP and no sealer extrusion at the 1-year follow-up.
METHODS: In a retrospective case-control study conducted from September 2016 to September 2021, teeth presenting clinical and radiographic signs of AP prior to treatment were included. The study comprised 2 groups: AH Plus sealer extrusion group (n = 60): initial root canal treatment or nonsurgical retreatment with unintentional apical extrusion of AH Plus sealer; and no AH Plus sealer extrusion group (n = 60): underwent the same treatment types without sealer extrusion. Additional factors, including sex, age, tooth type, tooth location, and treatment type, were recorded as potential outcome predictors. At 1-year follow-up, teeth were evaluated clinically and radiographically, and outcomes were classified as favorable (healed/healing) or unfavorable (uncertain/non-healing). Statistical analyses, such as the χ2 test, logistic regression, and Mann-Whitney U test, were employed for data analysis.
RESULTS: A favorable outcome was observed in 88.4% and 85% of the cases of the AH Plus sealer extrusion and no AH Plus sealer extrusion groups, respectively. There was no statistically significant difference between the groups in terms of outcomes (P > .05) when analyzed categorically or ordinally. Of independent variables, nonsurgical retreatment showed lower healing of AP in both groups.
CONCLUSIONS: Unintentional AH Plus sealer extrusion did not affect the healing of AP. However, initial root canal treatment showed better healing of AP than nonsurgical retreatment in the presence of AH Plus sealer extrusion. The analyzed outcome predictors had no effect on treatment outcome.

摘要：
背景：本研究旨在研究在1年的随访中，与使用AP和无密封剂挤压的牙齿相比，意外AHPlus®密封剂挤压对非手术根管治疗和再治疗的影响。
方法：在2016年9月至2021年9月进行的一项回顾性病例对照研究中，纳入了治疗前出现AP临床和影像学征象的牙齿。该研究包括两组：AHPlus®密封剂挤出（n=60）：初始根管治疗或非手术再治疗，意外根尖挤出AHPlus®密封剂；没有AHPlus®密封剂挤出（n=60）进行相同的处理，没有密封剂挤出。其他因素,包括性,年龄,齿型,牙齿位置,和治疗类型，被记录为潜在的结果预测因子。在1年的随访中，对牙齿进行了临床和影像学评估，结果分为有利（治愈/愈合）或不利（不确定/未愈合）。统计分析，如χ2检验，逻辑回归，和Mann-WhitneyU测试,用于数据分析。
结果：在AHPlus®封口机挤出组和没有AHPlus®封口机挤出组的病例中，分别有88.4%和85%观察到了良好的结果。分别。当进行分类或顺序分析时，两组之间的结果没有统计学上的显着差异（p>0.05）。在独立变量中，非手术再治疗显示两组AP愈合较低.
结论：意外的AHPlus®密封剂挤压并不影响AP的愈合。然而,在AhPlus®密封剂挤压术存在的情况下，初始根管治疗显示AP的愈合优于非手术再治疗。分析的结果预测因子对治疗结果没有影响。
