The aim of this study was to assess the relationship between glycemic control of type 1 diabetic (DM1) patients and hyposalivation and xerostomia. This observational transversal study used a quantitative approach with a sample of 25 DM1 patients enrolled at the Diabetes Association of Joinville (ADIJO) in 2008. Variables assessed were sialometry through stimulated salivary flow, complaints of xerostomia, and testing for glycemic control: fasting capillary glycemia (FCG) and glycated hemoglobin (HbA1c). The Mann-Whitney U test, chi-square test, and Fisher’s exact test were used to verify a possible association among the variables. Most subjects (64%; 16/25) showed concomitant hyposalivation and xerostomia. No significant statistical difference between glycemic control (FCG and HbA1c), hyposalivation, and xerostomia (p=0.54) was found. A high prevalence of hyposalivation and xerostomia was found to be more closely related to higher FCG values at the moment of blood testing than to higher values of HbA1c.
