Associations between remaining teeth and salivary flow, activity of daily living, and cognitive impairment among the elderly in a rural area: A pilot study / 대한구강보건학회지
Mean age (SD) of the participants was 83.77 (5.99) years and 68.9% of them were women. The participants who had a lower number of remaining teeth were significantly older, had severe cognitive impairment, and poor ADL and MNA results. The participants with severe cognitive impairment were significantly older and had fewer remaining teeth and low salivary flow. Simple linear regressionanalysis showed an association between remaining teeth and cognitive impairment with a P-value of 0.000, which disappeared after adjusting for sex and age or sex, age, denture use, and salivary flow, respectively.
