All of these findings support that the age (which seemed the only independent variable) shows strong correlation with the presence of the fatty infiltration but obesity may also play important role in the development and the extent of this change. Because of its frequency in elderly, at least partly, the fatty infiltration might be responsible for the xerostomia. We also think that presence of fatty infiltration should be mentioned in the histopathological report of salivary gland biopsies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
