Background: Diabetes mellitus, characterized by hyperglycemia, is associated with an increased susceptibility to infections, including periodontal diseases. Periodontitis, an inflammatory condition of the supporting structures of teeth, has been linked to systemic inflammation and insulin resistance, aggravating the diabetic state. NSPT, involving procedures such as scaling and root planning, aims to control periodontal infections and reduce inflammation, potentially influencing the systemic health of diabetic individuals.
