Abstract：
OBJECTIVE: Loupe magnification is a commonly utilized tool within dental education due to its proposed benefits of improving working posture, visual acuity, and procedural quality. Although procedural quality has been researched at the graduate level, literature encompassing the undergraduate level remains scarce. Therefore, this systematic review aims to critically assess the available literature to ascertain the effects of loupe magnification on the performance of undergraduate dental students\' cavity preparations.
METHODS: A systematic search was conducted across electronic databases, including PubMed, MEDLINE via Ovid, The Cochrane Library for Cochrane Reviews, and Scopus, to identify relevant studies published from inception to February 15, 2023. We included English language studies that evaluated the effect of loupe magnification on the performance of undergraduate dental students in cavity preparations.
RESULTS: In total, six studies fulfilled the inclusion criteria. The outcomes assessed encompassed tooth preparation accuracy. Of these six articles, one was conducted on endodontic access cavity preparations, four on restorative cavity preparations, and one on nonstandard cavity preparation designs performed on acrylic blocs. Four articles determined that loupes positively impacted undergraduate students\' performance in cavity preparations, while two articles established no significant difference in performance between loupes and naked-eye cavity preparations.
CONCLUSIONS: This systematic review suggests that loupe magnification positively impacts undergraduate dental students\' performance in cavity preparations. However, the heterogeneity of the studies and the variations in methodologies limit the ability to draw definitive conclusions.

摘要：
目的：放大倍数是牙科教育中常用的工具，因为它建议改善工作姿势，视敏度,和程序质量。尽管程序质量已经在研究生阶段进行了研究，涵盖本科水平的文献仍然很少。因此,本系统综述旨在批判性地评估现有文献，以确定放大镜放大对本科牙科学生腔准备的表现的影响。
方法：对电子数据库进行了系统搜索，包括PubMed,MEDLINE通过Ovid,Cochrane图书馆的Cochrane评论，还有Scopus,确定从开始到2023年2月15日发表的相关研究。我们纳入了英语语言研究，以评估放大镜放大对牙科本科生在腔内准备中的表现的影响。
结果：总计，6项研究符合纳入标准.评估的结果包括牙齿准备的准确性。在这六篇文章中，其中一项是在牙髓进入腔准备上进行的，四个关于修复腔的准备，以及在丙烯酸嵌段上进行的非标准空腔制备设计。四篇文章确定，放大镜积极影响本科生在腔准备中的表现，而两篇文章在放大镜和裸眼腔制剂之间的性能没有显着差异。
结论：本系统评价表明，放大镜放大倍数对牙科本科生在口腔准备方面的表现有积极影响。然而,研究的异质性和方法的差异限制了得出明确结论的能力。
