The aim of this study was to compare the 5-year outcomes of glass fiber composite with cast posts and cores for the restoration of endodontically treated teeth.
A total of 143 patients in need of 203 full ceramic restorations on endodontically treated teeth were included. After primary stratification based on the need for post or no post, teeth were randomly allotted to test group 1 (prefabricated glass fiber posts), 2 (custom-made glass fiber posts), or 3 (composite cores without posts). The control group was treated with gold alloy-based wrought posts and cast cores. Success (original present) and survival (present after intervention) probability lifetime curves, corrected for clustering, were drawn over the entire data set.
The mean follow-up time was 5.8 years (range: 0.5 to 7.2 years). At 5 years, the success and survival probabilities were 85.2% and 91.5%, respectively. Lifetime curves did not show any significant differences between the test and control groups for success (P = .85) or survival (P = .57). Moreover, no significant differences for success or survival could be found among the four groups (the three test groups and the control group).
After 5 years of follow-up, cast gold and composite post-and-core systems on teeth with ceramic full restorations provided with a ferrule performed equally well.
本研究旨在比较玻璃纤维复合材料与铸造桩核用于根管治疗后牙齿修复的5年疗效。
共纳入143例需要对根管治疗后的牙齿进行203颗全瓷修复的患者。在根据是否需要桩进行初步分层后，将牙齿随机分配至试验组1（预成玻璃纤维桩）、试验组2（定制玻璃纤维桩）或试验组3（无桩复合核）。对照组采用金合金锻造桩和铸造核进行治疗。针对整个数据集绘制了校正聚类后的成功（最初存在）和生存（干预后存在）概率寿命曲线。
平均随访时间为5.8年（范围：0.5至7.2年）。5年时，成功概率和生存概率分别为85.2%和91.5%。寿命曲线显示试验组和对照组在成功（P = 0.85）或生存（P = 0.57）方面无显著差异。此外，四组（三个试验组和对照组）之间在成功或生存方面也未发现显著差异。
经过5年的随访，对于进行了全瓷修复且带有箍的牙齿，铸造金桩核系统和复合桩核系统的疗效相当。
