Photography is becoming an increasingly important tool in the dental profession. But documentation of orthodontic or orthognathic treatment with pretreatment and posttreatment photographs can be misleading if features on one or both photographs are distorted. The dental photographer must be constantly aware of the importance of standardizing photographic variables when documentation of change is important. Although total reproducibility may not be practical, the photographer can establish a reasonably standardized approach to photographing patients. In this article the authors present the major considerations for frontal and profile facial photographs. Lens selection, camera position, subject distance, and position are all variables to be understood and controlled if accurate reproduction is desired. Numerous frontal and lateral photographs were made with head position, camera position, jaw position, and lens focal length changed to allow assessment of their contribution to the final picture. Using easily recognized facial landmarks, dental photographers can standardize frontal and lateral portraits for more consistent comparison.
摄影在牙科领域正变得越来越重要。但是，如果一张或两张照片上的特征被扭曲，那么用治疗前和治疗后的照片记录正畸或正颌治疗可能会产生误导。当记录变化很重要时，牙科摄影师必须始终意识到标准化摄影变量的重要性。尽管完全可重复性可能不切实际，但摄影师可以建立一种合理标准化的患者拍摄方法。在本文中，作者介绍了正面和侧面面部照片的主要注意事项。如果想要准确再现，镜头选择、相机位置、拍摄对象距离和位置都是需要理解和控制的变量。通过改变头部位置、相机位置、颌骨位置和镜头焦距拍摄了大量正面和侧面照片，以评估它们对最终照片的影响。牙科摄影师可以利用易于识别的面部标志，对正面和侧面人像进行标准化，以便进行更一致的比较。
