Abstract
This study aimed to determine the prevalence of oral mucosal lesions and risk factors among the institutionalized elderly Lebanese population. A representative sample of 526 individuals (49% males and 61% females) aged 65 years and above was examined. A questionnaire and clinical examination were administered. Bivariate and multivariate regressions were carried out. The frequency of oral mucosal lesions was 22.8% and it was associated to the use, integrity (p < .002), and hygiene level (p < .047) of removable mandibular and maxillary prosthesis. Multiple regression analysis also predicted the relationship between the mandibular prosthesis hygiene level and the occurrence of mucosal lesions. The factors controlling the occurrence of oral mucosal lesion were mainly related to the level of oral care given to the individuals. Therefore, a proper oral health care system should be implemented in the Lebanese residential homes to ensure the well-being of the residing population.
