The aim of this study was to compare the success rate of root canal treatments undertaken using a calcium silicate root canal sealer in combination with a single cone with non-calcium silicate cement and warm vertical condensation.
150 necrotic or pulpitic teeth were treated. (REC: 08/H0804/79). Following standardized root canal chemo-debridement. The canals were obturated using warm vertical condensation of gutta-percha and epoxy-based sealer (AH plus) or a calcium silicate sealer (BioRoot RCS) with a single cone technique. Follow-up assessment was conducted at 12 months using Cone Beam Computed Tomography (CBCT).
At 1-year recall, 104 teeth were assessed (51 AH plus, 53 BioRoot RCS). The success rate using loose criteria for the CBCT images and PA radiographs was respectively 80% and 89% in the AH plus/warm vertical condensation group, 84% and 90% in the BioRoot RCS/single cone group. There was no statistically significant difference between the two groups (Fisher exact test value 0.6099 for the CBCT images).
Within the limitations of this non-randomized trial, a calcium silicate cement in combination with single cone resulted in a similar proportion of successful cases compared to warm vertical condensation and epoxy-based sealer.
本研究的目的是比较使用硅酸钙根管封闭剂与单锥技术联合应用,和使用非硅酸钙水门汀及热垂直加压技术进行根管治疗的成功率。
对150颗坏死或牙髓炎患牙进行治疗(REC:08/H0804/79)。在进行标准化的根管化学清创后,使用牙胶热垂直加压技术和环氧类封闭剂(AH plus)或采用单锥技术使用硅酸钙封闭剂(BioRoot RCS)对根管进行充填。在12个月时使用锥形束计算机断层扫描(CBCT)进行随访评估。
在1年的回访中,评估了104颗牙齿(51颗使用AH plus,53颗使用BioRoot RCS)。对于CBCT图像和根尖片,采用宽松标准时,AH plus/热垂直加压组的成功率分别为80%和89%,BioRoot RCS/单锥组的成功率分别为84%和90%。两组之间无统计学显著差异(CBCT图像的Fisher精确检验值为0.6099)。
在本非随机试验的局限性范围内,与热垂直加压技术和环氧类封闭剂相比,硅酸钙水门汀与单锥技术联合应用的成功病例比例相似。
