| Research Abstract |
Present study suggested the following results; evaluation of masticatory and swallowing function using videofluorography was established, and eating with a conscious effort differed bolus transport from the oral cavity to the pharynx and improved swallowing easiness. Full palatal coverage by a denture base declined masticatory function, but swallowing function could compensate declined bolus formation. Additionally, the number of masticatory strokes until swallowing increased significantly after seven days adaptation. As a result, duration of swallowing and swallowing easiness were recovered.
Furthermore, it was clarified that wearing complete dentures was important for the bolus formation and the bolus transport during eating, suggesting that oral rehabilitation recovered declined swallowing reserve and might improve pharyngeal residue and aspiration.
