Background: This study aimed to determine how common oral candidiasis is in individuals with diabetes mellitus and to assess its connection with poor glycemic control and other health factors. Methodology: A cross-sectional analysis was performed with 150 diabetic patients from a HITEC - IMS Taxila. Individuals with confirmed type 1 or type 2 diabetes were included. Oral examinations were conducted to detect candidiasis, and microbiological tests using oral swabs confirmed diagnoses. Blood tests were also done to assess fasting glucose and HbA1c levels for glycemic control. Patient histories regarding diabetes duration and related complications were documented.
