Dose-response relationship between periodontal inflamed surface area and HbA1c in type 2 diabetics.

Background: A dose-response relationship between the amount of inflamed periodontal tissue and HbA1c level, might be indicative for a causal association between periodontitis and type 2 diabetes.

Aim: To assess a dose-response relationship between the periodontal inflamed surface area (PISA), as a measure of the amount of inflamed periodontal tissue, and HbA1c levels in type 2 diabetics.

Material And Methods: Forty consecutive dentate type 2 diabetics attending their general practitioner for regular check-up, underwent full-mouth probing pocket depth and bleeding on probing assessment.
