Objective: To investigate the effect of periodontal therapy on blood sugar level of non-insulin dependent diabetes mellitus(NIDDM) diabetics with periodontitis.
Methods: Patients with unfavorable control of diabetes were selected from out patients of the first affiliated hospital of Sun Yat-sen University of Medical Science. The percentage of bleeding on probing, probing depth and glycosylated hemoglobin level were studied at baseline, four weeks and eight weeks after non-surgical treatment.
Results: The percentage of bleeding on probing and probing depth were significantly reduced in all the patients after treatment. The mean glycosylated hemoglobin level were significantly decreased in patients with advanced periodontitis while patients with moderate periodontitis showed no changes following therapy.
Conclusions: The control of periodontal inflammation can improve metabolism to some extent in patients with diabetes mellitus, but the effect may relate to blood sugar level and periodontal conditions at baseline.
