There are three principal reasons for adopting magnifying loupes for operative dentistry: to enhance visualization of fine detail, to compensate for the loss of near vision (presbyopia) and to ensure maintenance of correct posture. The wearing of loupes is becoming an accepted norm amongst qualified practitioners and increasingly in the undergraduate population. However, further research is required before evidence-based recommendations can be made about their effectiveness in achieving the three principles. Compared to the medical literature, there is a paucity of studies on the use of loupes in dentistry. This article presents an overview of the well-documented (but under-researched) optical and ergonomic benefits of wearing loupes and highlights special circumstances where the use of loupes would be inadvisable. The article concludes with a review of the small number of studies on magnifying loupes specifically for restorative dentistry.
The reader should consider the information in this article prior to the purchase of magnifying loupes.
在口腔手术中采用放大镜有三个主要原因：增强对细微细节的可视化、弥补近视力丧失（老花眼）以及确保保持正确姿势。佩戴放大镜在合格从业者中甚至在本科生群体中越来越成为一种公认的常态。然而，在能够基于证据就其在实现这三个原则方面的有效性提出建议之前，还需要进一步研究。与医学文献相比，关于在牙科中使用放大镜的研究较少。本文概述了佩戴放大镜已充分记录（但研究不足）的光学和人体工程学益处，并强调了不适合使用放大镜的特殊情况。文章最后回顾了专门针对修复牙科的少量关于放大镜的研究。
读者在购买放大镜之前应考虑本文中的信息。
