A comparison of colorimetric and visual methods for the assessment of masticatory performance with color-changeable chewing gum in older persons

摘要

Color-changeable chewing gum is used for the evaluation of masticatory performance. However, it is currently unclear whether colorimetric and visual assessment methods yield consistent results. This study aimed to clarify the consistency between colorimetric and visual methods used for the evaluation of color changes in color-changeable chewing gum.
