title: [The effect of periodontal initial therapy on circulating TNF-alpha and HbA1C in type 2 diabetes patients with periodontitis].
abstract: OBJECTIVE
  To investigate the effect and mechanism of periodontal initial therapy on type 2 diabetes patients with periodontitis.
  
  
  METHODS
  15 type 2 diabetes patients with periodontitis were selected. Their body mass index (BMI), sulcus bleeding index (SBI), probing depth (PD), circulating tumor necrosis factor-alpha (TNF-alpha) concentration, and the value of glycosylated hemoglobin (HbA1C), triglycerides (TG) and cholesterol (CHOL) were assessed respectively before and 4-6 weeks after periodontal initial therapy.
  
  
  RESULTS
  After initial therapy, SBI, PD, circulating TNF-alpha concentration, and the value of HbA1C and TG were reduced significantly (P<0.05), while there were no significant differences in BMI and CHOL value (P>0.05).
  
  
  CONCLUSIONS
  Periodontal initial therapy can effectively reduce HbA1C value in type 2 diabetes patients with periodontitis, possibly through the reduction of circulating TNF-alpha concentration.
