To overview dental magnification loupes and to present the updated scientific evidence supporting its use.
The practice of dentistry places considerable stress on the operators' visual acuity and musculoskeletal system. The use of magnification loupes has spanned many decades with claims of supporting visual and postural capacities of dental professionals and enhancing diagnostic and procedural accuracy.
Galilean and prismatic loupes both provide lightweight and clinically appropriate magnifications between 2.5× and 5.0×, with beneficial features such as a fixed working distance and downward lens inclinations. Studies have found significantly increased detection and diagnostic abilities due to enhanced visibility and improved treatment outcomes for some investigated procedures. Postural studies have found improved positioning of the upper body when using loupes as compared to the positioning when using the naked eye, with practitioners experiencing reductions in musculoskeletal symptoms when using magnification loupes.
The current evidence supports the presence of some visual advantages of loupe magnification in diagnosis and treatment delivery. However, more clinical trials are needed to investigate different procedure outcomes over the long term. Further, there is robust scientific evidence advocating the use of loupe magnification for postural and musculoskeletal support.
Dentistry is a visually and physically demanding profession with a high prevalence of musculoskeletal disorders among dental professionals. The use of loupe magnification potentially benefits both the dental healthcare provider and patients. Therefore, there is reason to consider the use of loupe magnification as an integral part of dental education and training, as well as a tool in the dental clinician's armamentarium.
综述牙科放大镜，并介绍支持其使用的最新科学证据。
牙科操作对操作人员的视力和肌肉骨骼系统要求很高。使用放大镜已经有几十年的历史了，其声称可以支持牙科专业人员的视觉和姿势能力，并提高诊断和操作的准确性。
伽利略和棱镜放大镜都提供了 2.5×至 5.0×之间的轻量级和临床适当的放大倍数，具有固定工作距离和向下倾斜的镜片等有益特征。研究发现，由于增强了可见度和改善了一些调查程序的治疗效果，显著提高了检测和诊断能力。姿势研究发现，与使用裸眼相比，使用放大镜时上半身的位置得到了改善，并且当使用放大镜时，从业者的肌肉骨骼症状减少。
目前的证据支持放大镜在诊断和治疗中的一些视觉优势。然而，需要更多的临床试验来长期调查不同程序的结果。此外，有强有力的科学证据支持使用放大镜来支撑姿势和肌肉骨骼。
牙科是一项对视觉和身体要求很高的职业，牙科专业人员中肌肉骨骼疾病的患病率很高。使用放大镜放大可能对牙科医疗保健提供者和患者都有益。因此，有理由将放大镜的使用视为牙科教育和培训的一个组成部分，以及牙科临床医生工具包中的一个工具。
