The aims of this study were to determine the prevalence of oral sensorial complaints, salivary flow rate and oral mucosal lesions in the institutionalized and non-institutionalized elderly. The study included 280 institutionalized and 61 non- institutionalized elderly people. Dry mouth, burning mouth sensations, taste disturbances, salivary flow rate and oral mucosal lesions were assessed and compared between groups. A greater number of the institutionalized elderly had dry mouth (P = 0·001) and taste disturbance (P = 0·035) compared to non-institutionalized elderly. The institutionalized elderly also had significantly lower salivary flow rate (P < 0·0001). Positive correlation was found between salivary flow rate and perception of dry mouth in the institutionalized elderly (rs = 0·26 ; P < 0·05), as well as in the non-institutionalized elderly (rs = 0·35 ; P < 0·05). Moreover, positive correlation was observed between salivary flow rate and the sensation of burning mouth in the institutionalized elderly (rs = 0·13 ; P < 0·05) and non-institutionalized elderly (rs = 0·31 ; P < 0·05). The number of institutionalized elderly people with oral mucosal diseases was higher compared with non-institutionalized ones (P = 0·01). The most common oral mucosal lesions in both groups were related to wearing dentures. It can be concluded that the institutionalized elderly are significantly affected with oral sensorial complaints, including dry mouth and taste disturbance, as well as decreased salivary flow rate and oral mucosal diseases compared with the non-institutionalized elderly.
