RESUMO
OBJECTIVE: To 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. METHODS: Patients 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. RESULTS: The 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). CONCLUSION: Non-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.

OBJECTIVE: To investigate the effect of different inner metal materials of porcelain-fused-to-metal (PFM) crown on periodontal tissue by means of measuring the level of soluble intercellular adhesion molecule-1 (sICAM-1) and interleukin-1beta (IL-1beta) in gingival crevicular fluid (GCF) after PFM restorations. METHODS: 30 teeth were divided into three groups (Ni-Cr alloy group, Co-Cr alloy group and Au-Pt alloy group, 10 teeth each group), and restored by Ni-Cr alloy, Co-Cr alloy and Au-Pt alloy PFM crown according grouping. At the point of pre-restoration, 6-month and 12-month after cementation, the clinical parameters including plaque index (PLI), gingival index (GI) and gingival crevice depth (GCD) were detected, and GCF was collected from labial and lingual of mesial site and distal site. The level of sICAM-1 and IL-1beta were detected. RESULTS: At the point of 6-month and 12-month after cementation, Ni-Cr alloy group showed significant difference for GI, GCD and all GCF indexes when compared to pre-restoration, Co-Cr alloy group and Au-Pt alloy group (P < 0.05). At the point of 12-month after cementation, Co-Cr alloy group showed significant difference for GI, GCD and all GCF indexes when compared to pre-restoration and Au-Pt alloy group (P < 0.05). All indexes have no significant difference for Au-Pt alloy group during the 12-month experiment times when compared to pre-restoration (P > 0.05). CONCLUSION: Non-noble metal has bad effect on the periodontal tissue.
