Calcium silicate sealer (CSS) based obturation (SBO) has gained wide popularity for its relative simplicity and material biocompatibility. Limited information exists how its treatment outcome compares to warm-vertical compaction (WVC). The primary aim of this randomized controlled clinical trial was to compare the outcome of nonsurgical root canal treatment using SBO with CSS versus WVC with a resin-based sealer. The secondary aim was to assess differences in the obturation time between SBO and WVC.
A total of 195 participants with 212 teeth took part in this study and randomly allocated to either SBO or WVC after completion of the bio-mechanical instrumentation. The time required to complete the obturation was recorded. Participants were followed-up after a minimum of 12 months for clinical and radiographic assessment using periapical radiographs with the periapical index (PAI) and cone-beam computed tomography (CBCT) scans using the CBCT-PAI. Statistical evaluation involved descriptive analysis and binary logistic regression.
One hundred eighty-one teeth in 167 participants were followed-up (85.4%) after 12-22 months (mean 12.9 months). Using strict criteria, success rates were 76.6% for SBO and 80.5% for WVC based on PAI, and 71.3% for SBO and 65.5% for WVC using CBCT-PAI. The overall success was 78.5% assessed using PA radiographs and 68.5% using CBCT with no significant differences in outcomes. SBO required significantly less time (85.4 ± 44.0s) to complete the root filling compared to WVC (159.7 ± 71.0s) (P < .001).
Given comparable clinical outcomes to WVC yet demonstrating faster obturation time, SBO with CSS may be a suitable clinical alternative.
基于硅酸钙封闭剂（CSS）的根管充填术（SBO）因其相对简单和材料生物相容性而广受欢迎。关于其治疗效果与热垂直加压充填术（WVC）相比的信息有限。这项随机对照临床试验的主要目的是比较使用CSS进行SBO与使用树脂基封闭剂进行WVC的非手术根管治疗效果。次要目的是评估SBO和WVC在充填时间上的差异。
共有195名参与者的212颗牙齿参与了本研究，在完成生物力学预备后随机分为SBO组或WVC组。记录完成充填所需的时间。参与者在至少12个月后接受随访，使用根尖片的根尖指数（PAI）进行临床和影像学评估，并使用CBCT-PAI进行锥形束计算机断层扫描（CBCT）。统计评估包括描述性分析和二元逻辑回归。
167名参与者的181颗牙齿在12 - 22个月（平均12.9个月）后接受了随访（85.4%）。根据严格标准，基于PAI，SBO的成功率为76.6%，WVC为80.5%；使用CBCT-PAI时，SBO为71.3%，WVC为65.5%。使用根尖片评估的总体成功率为78.5%，使用CBCT为68.5%，结果无显著差异。与WVC（159.7 ± 71.0秒）相比，SBO完成根管充填所需时间显著更少（85.4 ± 44.0秒）（P <.001）。
鉴于与WVC具有相当的临床效果且充填时间更快，使用CSS的SBO可能是一种合适的临床替代方法。
