Background: The diagnosis of Type 2 Diabetes Mellitus (T2DM) is made by demonstrating the hypoglycemic condition, which involves the determination of plasma glucose, and the follow-up of hypoglycemic treatment is performed by assessing the glycated hemoglobin (HbA1c) concentration.
Aim: The aim of this study was to evaluate the saliva as an alternative sample in assessing the adherence to treatment with oral hypoglycemic agents in patients with Type 2 Diabetes.
Methods: We selected 68 patients with T2DM, who were subjected to venous blood and saliva collection, in addition to answering a standardized questionnaire on adherence to hypoglycemic treatment.
