The article presented here explains how the use of microscope-level magnification (6x to 8x or greater), combined with head-mounted, co-axial illumination, may improve a dentist's ability to extract teeth over the use of unaided vision or entry-level 2.5x magnification loupes and operatory lighting. Magnification improves a dentist's ability to detect tooth particle perimeters and to determine if luxation forces applied using elevators result in microscopic incremental improvements in tooth particle luxation. Magnification also improves a dentist's ability to distinguish between tooth structure and alveolar bone, which is useful when sectioning teeth and removing intra-socket alveolar bone to facilitate forceps extraction. In dentistry, the use of microscopes may facilitate a dentist's ability to perform dentoalveolar extractions with more conservative removal of alveolar bone, potentially minimizing trauma to the extraction site.
本文介绍了如何通过使用显微镜级放大倍数（6倍至8倍或更高），结合头戴式同轴照明，相较于仅依靠肉眼或入门级2.5倍放大倍数的放大镜及手术照明，可能会提高牙医拔牙的能力。放大倍数可提高牙医检测牙齿颗粒周边的能力，并确定使用牙挺施加的脱位力是否能使牙齿颗粒脱位在微观上逐步改善。放大倍数还能提高牙医区分牙齿结构和牙槽骨的能力，这在分割牙齿和去除牙槽窝内的牙槽骨以利于用钳子拔牙时很有用。在牙科领域，使用显微镜可能有助于牙医在更保守地去除牙槽骨的情况下进行牙槽突拔牙，从而有可能将拔牙部位的创伤降至最低。
