Denture-related oral mucosal lesions in Alzheimer disease: a case-control study.

The aim of this case-control study was to evaluate the association between denture-related oral mucosal lesions and Alzheimer disease (AD) in older adults (60 years and older). Seventy elderly adults (35 with AD and 35 classified as mentally healthy) were included in this study, which was carried out in a Brazilian medical center. Clinical data on oral lesions and mucosal findings were recorded, including alterations in the color or appearance of any lesions, if present. The influence of possible confounding factors, including sex, age, race, education level, health conditions, harmful habits, gait speed, and oral status (use of removable prostheses and denture hygiene), was analyzed. There was no statistically significant difference between groups in the frequency of denture-related oral mucosal lesions. Logistic regression analysis showed a higher prevalence of AD among individuals aged 80 years and older, those who were illiterate, users of tobacco, and patients with a slower gait. These results suggest that AD is not a risk factor for denture-related oral mucosal lesions.
