Abstract

This study aims to evaluate fracture resistance of simulated immature teeth after treatment with regenerative endodontic procedure (REP) using tricalcium silicate cements (TSCs) as cervical plugs. Bovine incisors were sectioned to standard crown/root ratio. Pulp tissue was removed and canals were enlarged to a standardized diameter. Teeth were then treated with a REP protocol consisting of NaOCl and EDTA irrigation, intracanal medication with triple-antibiotic paste for 14 days followed by a TSC cervical seal and composite restoration. Teeth were divided into groups according to the material used; Mineral-Trioxide-Aggregate (MTA), Biodentine, TotalFill. Teeth filled with guttapercha (GP) and intact teeth served as controls. All teeth subjected to an increasing compressive force (rate of 0.05 mm/s at a 45° angle to the long axis of the tooth) until fracture. All treated teeth exhibited significantly lower resistance to fracture compared to the intact teeth but no difference was found between the TSC groups (Kruskal-Wallis, Dunn's multiple comparison, p < .05). TSCs applied at the cervical area of simulated immature teeth treated with REP did not reinforce fracture resistance.

再生牙髓治疗模拟未成熟牙的抗折断性。
本研究旨在评估使用硅酸三钙骨水泥(TSCs)作为颈塞进行再生牙髓治疗(REP)后模拟未成熟牙齿的抗骨折性。将牛门牙切成标准的冠根比。去除牙髓组织,扩大管至标准直径。然后采用REP方案治疗牙齿,包括NaOCl和EDTA冲洗,管内使用三抗生素糊剂治疗14天,然后进行TSC颈椎密封和复合修复。根据所用的材料将牙齿分成不同的组;矿物-三氧化物-骨料(MTA),生物牙石,总填充。用GP填充的牙齿和完整的牙齿作为对照。所有牙齿都受到不断增加的压缩力(与牙齿长轴成45°角的速度为0.05 mm/s),直到断裂。与完整的牙齿相比,所有治疗过的牙齿都表现出明显较低的抗骨折性,但在TSC组之间没有发现差异(Kruskal-Wallis, Dunn's多重比较,p
