In super-aging society, masticatory and swallowing function is very important. The purpose of this study was to evaluate mastication by videoendoscopy often used for an assessment of pharyngeal swallowing. Subjects ate two colored (green and white) food with restrictive mastication times, and food bolus in oropharynx was observed by videoendoscopy. By increasing the number of mastication, the degree of color mixing was increased. Our results suggested that masticatory function could be evaluated by using videoendoscopy.
