The purpose of this present study was to investigate the influence of material filler and RGB values' fluctuation on creating a calibration curve, which indicates the relationship between material thickness and transmitted light brightness using the transillumination method. Creating the calibration curves were carried out through the following three methods; 1) the conventional method creates the calibration curve with a formula of thickness, 2) the maximum value method, with samples of a specified thickness, and 3) the actual value method, with a microscope. Furthermore, the reliability of each curve was verified via scanned artificial tooth data. In addition, the characteristics of light decrement were investigated. From our results, it was suggested that the filler diameter must be considered when the calibration curve is created using the bite impression material with a filler. In addition, it was suggested that the RGB values' fluctuation did not influence the calibration curve.

With Occluzer, testing should be carried out at clenching strength ≥ 60% MVC. With BiteEye, testing should be carried out from light clenching strength at 20% MVC to moderate clenching strengths at 40-60% MVC. Occluzer and BiteEye (10 μm) gave similar occlusal contact areas at 60-80% MVC. These results suggest that combined use of Occluzer and BiteEye gives an accurate picture of occlusion from weak to strong clenching strength.

In this report, reflected light which is a problem in the conventional transillumination method is explained, and a solution is proposed. The purpose of this report was to investigate the characteristics of transmitted and reflected light on the image of the recorded bite impression material, and to propose a method for distinguishing between the reflected light area and the occlusal contact area. Gray scale values in the transmitted and the reflected light areas were evaluated through the conventional transillumination method. The reflected light could not be distinguished from the contact area. From this result, it was revealed that the reflected light interfered with the observation of the occlusal contact via the conventional method. From the results of having evaluated RGB values in the transmitted and the reflected light areas, it was considered that the color difference between transmitted light and reflected light was useful to separate the transmitted and reflected light. Due to the adjustment of the offset and the gamma correction values, the reflected light could be distinguished from the occlusal contact area. It was considered that this method was helpful for accurately detecting the occlusal contact area on a digital photograph.
