Abstract:
Objective:To compare the effect of age and gender on mastication efficiency between healthy volunteers and dysphagic stroke survivors and to document any correlation of mastication efficiency with mandible movements.Methods:Thirty-two stroke survivors with dysphagia and 84 healthy volunteers were asked to chew two-color gum. Their chewing efficiency was indicated by the degree of color mixing after chewing (SDHue). The SDHue value was evaluated using ViewGum software. The healthy volunteers were further divided into an age 20-40 years group, a 41-60 years group and an over-60 group. The SDHue values were compared among the 3 groups. The SDHue values were correlated with clinical mandibule movement scores.Results:Among the healthy volunteers, those older than 60 years had significantly higher SDHue values on average than those between 20 and 40 years. However, no significant gender difference was observed. The dysphagic stroke survivors had, on average, significantly higher SDHue results than the healthy volunteers, and those results were positively correlated with their mandible movement scores.Conclusions:Mastication efficiency tends to be age-related but not gender-related. Among those with post-stroke dysphagia mandible movement is positively correlated with mastication efficiency.
