Comparison of proportion of mastication patterns of cognitive impairment and control group. Proportions of mastication patterns were shown between patients with CI and Control. Mastication pattern is further separated into early elderly group (ages 65 ~ 74) (A) and advanced elderly group (ages > 75) (B). 1/3 of all CI subjects had mastication patters with no teeth contact.
