Abstract

Background: Endodontically treated teeth need to be restored in a manner to provide protection for the remaining tooth structure but would also allow the restoration of esthetic and functional demands. Objectives: This study evaluates the clinical success rate of endodontically treated premolars restored with different techniques. Methods: In this study, 96 participants were included with indication of endodontic treatment of one maxillary or mandibular premolar. Only cases with premolars along with MOD Class II carious lesions and preserved cusp structure were recruited. After endodontic treatment subjects were randomly assigned to one of the following restoration methods: (1) composite restoration without any cusp reduction (2) Composite associated with a fiber reinforced composite (FRC) post (3) capping the buccal and lingual cusp and composite restoration. Subjects were recalled for the clinical and radiographical evaluations with modified USPHS criteria after three, six and 12 months. Results: During the evaluation period, all the three methods of restoration, achieved the Alpha degree in term of modified USPHS criteria. Conclusions: The clinical success rates of endodontically treated premolars restored with fiber posts and direct composite restorations, direct composite restorations with cusp capping and simple direct composite restoration were perfect after one year of follow-

一项前瞻性队列研究:不同直接修复技术根管治疗的前磨牙1年生存率的临床比较

背景:牙髓治疗后的牙齿需要以一种保护剩余牙齿结构的方式进行修复，但也要允许恢复审美和功能需求。目的:评价不同方法修复前磨牙的临床成功率。方法:本研究纳入96例有上颌或下颌前磨牙根管治疗指征的患者。我们只招募了前磨牙伴MOD II类龋齿且保留尖牙结构的病例。根管治疗后，受试者被随机分配到以下修复方法中的一种:(1)不复位尖的复合修复(2)结合纤维增强复合材料(FRC)桩的复合修复(3)覆盖颊尖和舌尖复合修复。受试者在3个月、6个月和12个月后按照修改后的USPHS标准进行临床和影像学评估。结果:在评价期内，3种修复方法均达到改良USPHS标准的Alpha度。结论:经根管治疗的前磨牙采用纤维桩+直接复合修复体、直接复合修复体加牙尖盖修复体和单纯直接复合修复体，随访1年后临床成功率均较好
