In the present study, we conducted the longitudinal study to elucidate a real relationship between the change of masticatory function and general health status. Also, we performed a cross-sectional survey every year during the study period to investigate the masticatory function evaluated by objective methods and health status including physical, mental, and social aspects. The assessment parameters of mastication were the number of present teeth, occlusal area, maximum bite force, and mastication score. On the other hand, the assessment parameters of general health status were higher level of competence evaluated by TMIG index, cognitive function evaluated by HDS-R, and QOL evaluated PGC morale scale.In the cross-sectional survey 1999, each parameter of masticatory function was related to the diet including juice and cola. Furthermore, in the cross-sectional survey 2000, score of TMIG index correlated each value of masticatory function in both of males and females (p<0.01). In section of PGC morale scale that assessed agitation, attitude towards own aging, and lonely dissatisfaction, masticatory function was correlated With attitude toward own aging in particular (p<0.05). Also, the score of HDS-R was related significantly to each parameter of masticatory function.From these cross-sectional data, masticatory function was associated closely to higher level of competence, cognitive function, and QOL. In the survey of final year, we conducted a longitudinal investigation using the stored data. The change of masticatory function which was found during the study period was related to the changes of higher level of competence and cognitive function (p<0.05). These data suggest that the improvement of masticatory function in the elderly contribute to the advance of physical, mental, and social health.
