OBJECTIVE
The aim of this study was to compare the visual assessment of tooth shade with the measurement using intraoral scanner (IOS) and spectrophotometer devices.
METHODOLOGY
The colour for a single unit implant supported crown was measured visually, using IOS, and spectrophotometer. The results of the digital methods were compared with the visual measurement.
RESULTS
A complete colour match with the visual measurement was in 42.9% of cases for IOS, and in 33.3% of cases for spectrophotometry. The match in the colour value, hue, and chroma were in 61.9%, 95.2%, and 66.7% of cases, respectively, for the IOS; and in 61.9%, 61.9%, and 66.7% of cases, respectively, for the spectrophotometry. The differences between the IOS and spectrophotometry were not statistically significant.
CONCLUSIONS
The most reliable method for tooth colour selection is the visual measurement by an experienced dentist. IOS and spectrophotometer can be used as an alternative method, however in both cases they should be verified using visual measurement.
目的
本研究旨在比较使用口腔内扫描仪（IOS）和分光光度计设备进行牙齿颜色测量与视觉评估的结果。
方法
对单颗种植体支持的牙冠颜色进行视觉测量、使用IOS测量以及分光光度计测量。将数字方法的测量结果与视觉测量结果进行比较。
结果
IOS测量结果与视觉测量完全匹配的情况占42.9%，分光光度法测量结果与视觉测量完全匹配的情况占33.3%。IOS测量在颜色值、色调和彩度方面与视觉测量匹配的情况分别占61.9%、95.2%和66.7%；分光光度法测量在颜色值、色调和彩度方面与视觉测量匹配的情况分别占61.9%、61.9%和66.7%。IOS测量与分光光度法测量之间的差异无统计学意义。
结论
牙齿颜色选择最可靠的方法是由经验丰富的牙医进行视觉测量。IOS和分光光度计可作为替代方法使用，但在这两种情况下都应通过视觉测量进行验证。
