Regarding the perception of xerostomia/dry mouth, 49.2% of the interviewees reported feeling moderate to severe dry mouth. With regard to gender, 41 (50%) women and 18 (47.4%) men reported moderate to severe xerostomia. A total of 27 (45%) individuals who used insulin and 32 (53.3%) individuals who did not use insulin reported moderate to severe xerostomia. This result is close to the results of the studies by Närhi et al.  and Collin et al. , in which over 50% of the interviewees complained of xerostomia. The perception of xerostomia may be explained by the use of medications with potential xerostomic effects– 92 (76.7%) patients used at least one drug with such side effects.
