Objective: This study aimed to investigate the effects of nasal obstruction on the coordinated movement of perioral tissues during mastication using a motion capture system.
Design: Twelve healthy adult participants were instructed to chew gum only on their habitual masticatory side for 30 s, with and without nasal obstruction. Nasal obstruction was induced by blocking nasal breathing with a nose clip.
Background: Evaluating mouth rinsing skills is useful for assessing oral function, however current evaluation methods are subjective.
Objectives: This study compared mouth rinsing between adults and children using a contactless camera to capture lip motion.
Methods: The subjects comprised 16 adults and 13 children with no oral dysfunction.
