Color inspection plays an important role in the diagnosis of oral mucosal lesions. However, it is sometimes difficult to diagnose by color, because color is always evaluated subjectively. In order to measure color objectively and quantitatively, we decided to use a newly developed spectrum colorimeter for the oral mucosa. To keep the same angle and distance, a special stick was utilized. Various experiments were performed and suitable conditions for accurate colorimetric measurement were decided, including room temperature with cooling fan, onset time of the device, calibration timing, and the angle between light and the measured surface. The reproducibility of this method was confirmed by measuring the color of the buccal mucosa in healthy persons.
颜色检查在口腔黏膜病变的诊断中起着重要作用。然而，有时仅凭颜色进行诊断会很困难，因为颜色评估总是主观的。为了客观、定量地测量颜色，我们决定使用一种新开发的用于口腔黏膜的光谱色度计。为了保持相同的角度和距离，使用了一根特殊的棒。进行了各种实验，并确定了准确比色测量的合适条件，包括带冷却风扇的室温、设备启动时间、校准时间以及光与被测表面之间的角度。通过测量健康人颊黏膜的颜色，证实了该方法的可重复性。
