Abstract

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.

数字方法在单片全瓷冠的颜色测定中足够成功吗?

目的:比较口腔内扫描(IOS)和分光光度计对牙影的视觉评价。方法:用肉眼测量单个种植体支撑冠的颜色，使用IOS和分光光度计。将数字测量结果与目测结果进行了比较。结果:眼压法和分光光度法的颜色完全匹配率分别为42.9%和33.3%。在IOS中，颜色值、色调和色度的匹配率分别为61.9%、95.2%和66.7%;在61.9%，61.9%和66.7%的情况下，分别为分光光度法。IOS与分光光度法的差异无统计学意义。结论:牙色选择最可靠的方法是由经验丰富的牙医进行目测。IOS和分光光度计可以作为一种替代方法，但在这两种情况下，它们都应该使用视觉测量来验证。
