Background It is crucial dental students graduate with sound knowledge of endodontics and prosthodontics. The use of loupes is important for these due to their intricate nature, but there is currently no standardisation of curricula.Objective This systematic review investigates the value of including loupes in completing dental degrees and their benefits to dental students.Methods Literature was searched from inception to February 2022 in PubMed, Embase and Scopus. Articles included were primary studies of dental students studying endodontics or prosthodontics, which had outcomes related to the value of utilising loupes in learning, clinical application and ergonomics.Results A total of 1,489 articles were retrieved, of which 14 relevant articles were identified. These articles discussed student perceptions and the impact on visual acuity, ergonomic practices and dental procedures. Overall, students perceived that loupes increased self-confidence and allowed a greater operative view but were initially difficult to use. Using loupes resulted in greater visual acuity than no magnification and improved ergonomic practices by reducing neck angulation and improving posture. Students also received better grades when using loupes during cavity access preparation or root canal therapy.Conclusion The use of loupes by dental students can be beneficial if there is initial teaching on their use.
背景 牙科学生毕业时具备扎实的牙髓病学和口腔修复学知识至关重要。由于牙髓病学和口腔修复学性质复杂，使用放大镜对学习这些领域很重要，但目前课程设置尚无标准化。
目的 本系统评价调查在完成牙科学位过程中使用放大镜的价值及其对牙科学生的益处。
方法 从创刊至2022年2月在PubMed、Embase和Scopus数据库中检索文献。纳入的文章为关于学习牙髓病学或口腔修复学的牙科学生的原始研究，其结果与在学习、临床应用和人体工程学方面使用放大镜的价值相关。
结果 共检索到1489篇文章，其中确定了14篇相关文章。这些文章讨论了学生的看法以及对视力、人体工程学实践和牙科操作的影响。总体而言，学生认为放大镜增强了自信心，能提供更好的手术视野，但起初使用起来有困难。使用放大镜比不放大时视力更好，通过减少颈部角度和改善姿势改进了人体工程学实践。在窝洞预备或根管治疗期间使用放大镜时，学生的成绩也更好。
结论 如果对牙科学生进行关于放大镜使用的初步教学，使用放大镜可能会有益处。
