To systematically assess the influence of ambient light on the accuracy and scanning time of intraoral scanning.
The present systematic review (CRD 42022346672) was registered at the International Prospective Register of Systematic Reviews (PROSPERO) and was performed based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020. Electronic searches were conducted using PubMed, Web of Science, and EMBASE, complemented by gray literature, references, and citations of the included studies. The primary outcome was accuracy, and the scanning time was a secondary outcome. Owing to the high heterogeneity, the pooled data were analyzed descriptively.
Six in vitro and two in vivo experiments were performed. Three in vitro studies reported both the accuracy and scanning time of the intraoral scans, whereas the remaining studies exclusively evaluated the accuracy. The studies mainly investigated the influence of illumination levels (0-11000 lux) on intraoral scanning. Intraoral scans revealed optimal accuracy at 1000-lux illumination for complete-arch dentition scans, whereas the influence of illumination levels on 4-unit or shorter scans was not clinically significant. The intraoral scans obtained using confocal microscopy were less affected by the illumination levels than those obtained using the active triangulation technique. Furthermore, the scanning time tended to increase with increasing illumination.
Evidently from the limited number of studies conducted, ambient light illumination had considerable influence on the accuracy and scanning time of intraoral scanning, which appeared to be related to the scanning range and imaging technology.
系统评估环境光对口腔内扫描准确性和扫描时间的影响。
本系统评价（CRD 42022346672）已在国际系统评价前瞻性注册库（PROSPERO）注册，并根据系统评价和Meta分析的首选报告项目（PRISMA）2020指南进行。使用PubMed、科学网和EMBASE进行电子检索，并辅以灰色文献、纳入研究的参考文献和引用文献。主要结局为准确性，扫描时间为次要结局。由于异质性较高，对汇总数据进行描述性分析。
进行了6项体外实验和2项体内实验。3项体外研究报告了口腔内扫描的准确性和扫描时间，而其余研究仅评估了准确性。这些研究主要调查了光照水平（0 - 11000勒克斯）对口腔内扫描的影响。对于全牙列扫描，口腔内扫描在1000勒克斯光照下显示出最佳准确性，而光照水平对4单位或更短扫描的影响在临床上不显著。使用共聚焦显微镜获得的口腔内扫描受光照水平的影响小于使用主动三角测量技术获得的扫描。此外，扫描时间倾向于随着光照增加而延长。
显然，从已进行的有限数量研究来看，环境光照对口腔内扫描的准确性和扫描时间有相当大的影响，这似乎与扫描范围和成像技术有关。
