This study aimed to perform a systematic review of studies on factors related to xerostomia and/or hyposalivation in elderly patients with diabetes. SciELO, Science Direct, Scopus, and PubMed/Medline databases were searched for articles published from January 1992 to January 2013, concerned with factors associated with/related to xerostomia or hyposalivation in elderly patients with diabetes. Five articles were selected, including four transversal studies and one longitudinal study. Some of the studies found relationship between poor glycemic control and hyposalivation. Others found that xerostomia was more frequent in patients who worked in nondomestic environments and in women. However, there was considerable variation in the methods used by the researchers in the selected studies. We could not draw definitive conclusions based on our analysis of the selected studies. Longitudinal studies with appropriate sample sizes are needed to provide more complete information about the factors related to xerostomia and hyposalivation in elderly patients with diabetes.
