Various material properties are involved in the success of endodontically treated restorations. At present, restorative composites are commonly employed as core build-up materials. This study aimed to systematically review the literature to assess the effect of using composite core materials on the in vitro fracture of endodontically treated teeth. Two different reviewers screened the literature, up to June 2021, in five distinct electronic databases: PubMed (MedLine), Scopus, Scielo, ISI Web of Science, and EMBASE. Only in vitro studies reporting the effect of the use of composite core materials on the fracture resistance of endodontically treated teeth were included. A meta-analysis was carried out using a software program (Review Manager v5.4.1; The Cochrane Collaboration, Copenhagen, Denmark). The risk of bias in each study was assessed following the parameters of another systematic review. A total of 5016 relevant papers were retrieved from all databases. After assessing the title and abstract, five publications remained for qualitative analysis. From these, only three studies remained for meta-analysis. The fracture strength of endodontically treated teeth where a core build-up composite was used was statistically significantly higher than the control ( = 0.04). Most of the analyses showed a high heterogenicity. The in vitro evidence suggests that the composite core build-up with higher filler content tended to improve the fracture resistance of the endodontically treated teeth, in comparison with conventional composite resins. This research received no external funding. Considering that this systematic review was only carried out on in vitro papers, registration was not performed. Furthermore, there were no identified clinical studies assessing core build-up materials; therefore, more well-designed research on these materials is needed.
多种材料特性与根管治疗后修复体的成功有关。目前，修复性复合材料通常用作核桩材料。本研究旨在系统回顾文献，以评估使用复合核材料对根管治疗后牙齿体外抗折性的影响。两名不同的审阅者在五个不同的电子数据库中筛选了截至2021年6月的文献：PubMed（医学索引数据库）、Scopus、Scielo、科学引文索引网络版和EMBASE。仅纳入报告使用复合核材料对根管治疗后牙齿抗折性影响的体外研究。使用软件程序（Review Manager v5.4.1；丹麦哥本哈根的Cochrane协作网）进行荟萃分析。根据另一项系统评价的参数评估每项研究的偏倚风险。从所有数据库中检索到共5016篇相关论文。在评估标题和摘要后，保留五篇出版物进行定性分析。其中，仅三项研究纳入荟萃分析。使用核桩复合树脂的根管治疗后牙齿的抗折强度在统计学上显著高于对照组（P = 0.04）。大多数分析显示高度异质性。体外证据表明，与传统复合树脂相比，具有较高填料含量的复合核桩材料倾向于提高根管治疗后牙齿的抗折性。本研究未获得外部资金。鉴于本系统评价仅针对体外研究论文进行，未进行注册。此外，未发现评估核桩材料的临床研究；因此，需要对这些材料进行更多设计良好的研究。
