The purpose of this study was to assess the clinical and radiographic outcome of root-end microsurgery using a premixed fast-set calcium silicate putty as root-end filling material in human teeth.
This study included 50 teeth in 35 patients, whose ages ranged from 16 to 69 years. After clinical and radiographic examination, informed consent was obtained and one resident performed all surgical procedures using an endodontic microsurgical approach. A tricalcium silicate-based putty (TotalFil FS putty, FKG Dentair, La Chaux-de-Fonds, Switzerland) was used as a root-end filling material. Patients were recalled and treated teeth were examined clinically and radiographically at 3 months, 6 months, and 1 year postoperatively. The outcome was determined based on clinical and radiographic results. Radiographic healing was classified into 4 categories: complete, incomplete, uncertain, and unsatisfactory. Analysis of predictors was performed using the Pearson chi-square or Fisher's exact test.
At the time of surgery, 3 teeth were diagnosed with cracks and were excluded from the study. The recall rates were 85% at 3 months, 100% at 6 months, and 95% at 1 year. One tooth failed at 3 months, 3 failed at 1 year, with a success rate of 93%. None of the predictors investigated had a significant influence on the outcome of microsurgery.
Premixed fast-set tricalcium silicate putty is a suitable root-end filling material for use in endodontic microsurgery.
Tricalcium silicate-based cements have shown promising biological properties as a root-end-filling material. Premixed and fast-set formulations achieved high success rates in clinical studies.

本研究旨在评估使用预混快速凝固硅酸钙腻子作为人牙根管末端填充材料进行根管末端显微手术的临床和影像学效果。
本研究纳入了 35 名患者的 50 颗牙齿，年龄在 16 岁至 69 岁之间。经过临床和影像学检查后，获得知情同意书，并由一名住院医师使用根管显微外科方法进行所有手术操作。使用硅酸三钙基腻子（TotalFil FS 腻子，FKG Dentair，La Chaux-de-Fonds，瑞士）作为根管末端填充材料。患者被召回，术后 3 个月、6 个月和 1 年时对治疗牙齿进行临床和影像学检查。根据临床和影像学结果确定治疗效果。将影像学愈合分为 4 类：完全、不完全、不确定和不满意。使用 Pearson 卡方检验或 Fisher 确切检验分析预测因子。
在手术时，有 3 颗牙齿被诊断为裂纹，因此被排除在研究之外。3 个月时的召回率为 85%，6 个月时为 100%，1 年时为 95%。有 1 颗牙齿在 3 个月时失败，3 颗牙齿在 1 年时失败，成功率为 93%。研究中调查的预测因子均未对显微手术的结果产生显著影响。
预混快速凝固硅酸三钙腻子是一种适合用于根管显微手术的根管末端填充材料。
硅酸三钙基水泥作为根管末端填充材料具有有前途的生物学特性。预混和快速凝固配方在临床研究中取得了高成功率。
