Background: The purpose of this study was to evaluate the expression of inducible nitric oxide synthase (iNOS) in the gingival tissues of periodontitis patients with and without type 2 diabetes to assess whether NO plays a role in the severity of periodontitis in patients with diabetes. Patients with diabetes and healthy patients were used as controls.
