Abstract
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.
