Abstract：
This systematic review aimed to investigate whether minimally invasive root canal preparation ensures higher fracture resistance compared to conventional root canal preparation in endodontically treated teeth (ETT). A comprehensive search strategy was conducted on the \"PubMed, Web of Science, and Scopus\" databases, alongside reference and hand searches, with language restrictions applied. Two independent reviews selected pertinent laboratory studies that explored the effect of minimally invasive root canal preparation on fracture resistance, in comparison to larger preparation counterparts. The quality of the studies was assessed, and the risk of bias was categorized as low, moderate, or high. The electronic search yielded a total of 1,767 articles. After applying eligibility criteria, 8 studies were included. Given the low methodological quality of these studies and the large variability of fracture resistance values, the impact of reduced apical size and/or taper on the fracture resistance of the ETT can be considered uncertain. This systematic review could not reveal sufficient evidence regarding the effect of minimally invasive preparation on increasing fracture resistance of ETT, primarily due to the inherent limitations of the studies and the moderate risk of bias.
摘要：
本系统综述旨在研究与传统根管治疗（ETT）相比，微创根管预备是否可确保更高的抗断裂性。在“PubMed，WebofScience,和Scopus数据库，除了参考和手工搜索，应用语言限制。两个独立的评论选择了相关的实验室研究，探讨了微创根管预备对骨折阻力的影响，与较大的制剂同行相比。评估了研究的质量，偏见的风险被归类为低，中度,或高。电子搜索共产生1,767篇文章。在申请资格标准后，共纳入8项研究。鉴于这些研究的方法学质量低，断裂阻力值的变异性大，减小的顶端尺寸和/或锥度对ETT的抗断裂性的影响可以被认为是不确定的。本系统综述未能揭示关于微创准备对增加ETT抗骨折性的作用的充分证据。主要是由于研究的固有局限性和中等偏倚风险。
