This study aimed to evaluate the intensity of pain after unintentional extrusion of resin-based and calcium hydroxide (Ca[OH])-based endodontic sealers as well as their influence on the periradicular tissues.
A total of 120 single-rooted teeth exhibiting extrusion of sealer in the postoperative radiographs were included in the study. According to the sealers used, the teeth were divided into four groups ( = 30): Group I - AH Plus, Group II - Resino Seal, Group III - Sealapex™, and Group IV - Apexit Plus. Postoperative pain was assessed at 0-6 h, 6-12 h, 12-24 h, and 24-48 h of obturation using Visual Analog Scale. Radiographs were taken at 3, 6, and ≥9 months to 1-year follow-up and compared with baseline radiographs to assess the dissolution of extruded sealers and healing of periradicular tissues.
ANOVA, Kruskal-Wallis, and Pearson's Chi-square test were used. Statistical significance level was set at ≤ 0.05.
Postoperative pain intensity was higher in case of AH Plus sealer followed by Sealapex™ up to 12 h of obturation and was statistically nonsignificant. Apexit Plus at all time intervals showed statistically significant less pain intensity than AH Plus and Sealapex™ but not from Resino Seal group. At 9-month follow-up, better healing of periradicular tissues was shown by AH Plus (48.1%) followed by Apexit Plus (44.4%) and Sealapex™ (41.2%) with statistically nonsignificant difference.
In case of periapical extrusion, both resin-based and Ca(OH)-based sealers caused postoperative pain. Both Ca(OH)- and resin-based sealers did not influence the treatment outcome.
本研究旨在评估树脂基和氢氧化钙（Ca[OH]）基根管封闭剂意外挤出后的疼痛强度及其对根尖周组织的影响。
本研究纳入了120颗单根牙，这些牙齿在术后X线片上显示有封闭剂挤出。根据所使用的封闭剂，将牙齿分为四组（每组n = 30）：第一组 - AH Plus，第二组 - Resino Seal，第三组 - Sealapex™，第四组 - Apexit Plus。使用视觉模拟量表在根管充填后0 - 6小时、6 - 12小时、12 - 24小时和24 - 48小时评估术后疼痛情况。在3个月、6个月以及≥9个月至1年的随访时拍摄X线片，并与基线X线片进行比较，以评估挤出封闭剂的溶解情况和根尖周组织的愈合情况。
采用方差分析、Kruskal - Wallis检验和Pearson卡方检验。统计学显著性水平设定为P≤0.05。
AH Plus封闭剂术后疼痛强度较高，其次是Sealapex™，直至根管充填后12小时，且差异无统计学意义。在所有时间间隔内，Apexit Plus的疼痛强度在统计学上显著低于AH Plus和Sealapex™，但与Resino Seal组相比无差异。在9个月随访时，AH Plus（48.1%）显示根尖周组织愈合情况较好，其次是Apexit Plus（44.4%）和Sealapex™（41.2%），差异无统计学意义。
在根尖周挤出的情况下，树脂基和Ca(OH)基封闭剂均会引起术后疼痛。Ca(OH)基和树脂基封闭剂均不影响治疗结果。
