Objectives
Narrative objectives1 Dysphagia could often be observed in elderly population. Considering the achievement of daily nutrition, objective evaluation of masticatory function would be of importance. Distinguishing the foodstuffs which could be fully masticated would be an important information on improving QoL of the elderly.
This study aimed to evaluate digital images of food particles in masticated bolus, which were already taken in our university or other cooperating universities, to establish the data to support the availability of our masticatory efficiency evaluation system.
