This study aimed to investigate the extent to which intraoral scanning are affected by clinical conditions, and whether ambient lighting and different color temperatures have an impact on the accuracy of intraoral scanner, as well as to evaluate scanning time.
Twelve different environments were created using various ambient lighting conditions (0, 500, 1000 and 1500 lux) and color temperatures (white, blue and yellow). A partially edentulous mandibular model with two implants and a three-unit bridge was scanned under each environment until 10 digital models were obtained, and scanning times were recorded using a virtual stopwatch. A 3D analysis was performed on the obtained digital models, and the data were analyzed using a software. The generalized linear model analysis and Tukey multiple comparison test were used to analyse the data ( < .05).
The effect of lux, color temperature, and scanning times on RMS data was found to be significant ( < .001). The mean RMS value was the highest in the 0 lux group and the lowest in the 500 lux group. Regarding the color temperature, the highest RMS value was in the white color group and the lowest in the yellow color group. Scanning times were similar among the 0, 500 and 1000 lux groups, with a significant increase in the 1500 lux group.
Different ambient lighting conditions and color temperatures have significant effect on the accuracy of intraoral scanning.
本研究旨在调查临床条件对口腔内扫描的影响程度，以及环境光和不同色温是否会对口腔内扫描仪的准确性产生影响，并评估扫描时间。
利用各种环境光照条件（0、500、1000和1500勒克斯）和色温（白色、蓝色和黄色）创建了12种不同的环境。在每种环境下，对带有两颗种植体和一个三单位桥体的部分无牙下颌模型进行扫描，直至获得10个数字模型，并使用虚拟秒表记录扫描时间。对获得的数字模型进行三维分析，并使用软件对数据进行分析。采用广义线性模型分析和Tukey多重比较检验对数据进行分析（<.05）。
发现勒克斯、色温及扫描时间对均方根（RMS）数据的影响具有显著性（<.001）。均方根平均值在0勒克斯组中最高，在500勒克斯组中最低。关于色温，均方根值在白色组中最高，在黄色组中最低。0、500和1000勒克斯组的扫描时间相似，1500勒克斯组有显著增加。
不同的环境光照条件和色温对口腔内扫描的准确性有显著影响。
