No statistically significant association was found between the use of medications that caused xerostomia and salivation status. Reduced salivary flow was prevalent in the group assessed in the present research. However, this finding is not in accordance with the perception of xerostomia/dry mouth reported by the older patients. Such hyposalivation may be related to the many risk factors for reduction in salivary flow found in the group analyzed, particularly the advanced age, DM2 and tooth loss.
