OBJECTIVETo evaluate the effects of non-surgical periodontal treatment on clinical periodontal measurements, glycemic control, and level of serum soluble intercellular adhesion molecule-1 (sICAM-1) in type 2 diabetes mellitus with chronic periodontitis patients.

METHODSPatients with type 2 diabetes and chronic periodontitis were selected and classified into well-controlled group[glycated hemoglobin Ac(GHbA1)<7.00%, n=30, DMCP1 group] and poorly-controlled group (GHbAc > or = 7.00%, n = 30, DMCP2 group). Thirty systemically healthy patients with chronic periodontitis were recruited as control group (CP group). All subjects underwent non-surgical periodontal therapy. Plaque index(PLI), sulcus bleeding index(SBI), bleeding on probing (BOP), probing depth(PD), clinical attachment loss (CAL), serum sICAM-1 concentration, and the value of fasting plasma glucose(FPG), GHbAc were recorded at baseline, 1 and 3 months after periodontal treatment.

RESULTSThe three study groups showed significant improvements for the levels of PD, SBI, PLI, BOP, and serum sICAM-1 concentration at 1 and 3 months after non-surgical periodontal treatment (P < 0.05). The level of CP group and DMCP1 group also showed significant improvements for the levels of CAL (P < 0.05), but no significant change was found in DMCP2 group (P > 0.05). At 3 months after periodontal treatment, GHbA1c levels in DMCP2 group significantly decreased by 1.12% (P < 0.05), whereas no significant changes were found in CP and DMCT groups (P > 0.05).

CONCLUSIONNon-surgical periodontal treatment can siginificantly improve periodontal health status in patients with type 2 diabetes and periodontitis, reduce the level of serum sICAM-1, and can reduce the level of GHbA1c in poorly controlled type 2 diabetic patients.
