title: Effectiveness of full-mouth and partial-mouth scaling and root planing in treating chronic periodontitis in subjects with type 2 diabetes.
abstract: BACKGROUND
  This study evaluated the clinical and metabolic effects of full-mouth scaling and root planing (FMSRP) compared to partial-mouth scaling and root planing (PMSRP) in patients with type 2 diabetes and chronic periodontitis, and it assessed the impact of the glycemic status on the clinical and metabolic response to periodontal therapy.
  
  
  METHODS
  In this clinical trial, 18 subjects with diabetes received FMSRP in a maximum of 24 hours, and 18 subjects received PMSRP in a maximum of 21 days. Visible plaque accumulation, bleeding on probing, suppuration, probing depth, clinical attachment level (CAL), and glycosylated hemoglobin (HbA1c) levels were obtained at baseline and at 3 and 6 months post-therapy. Baseline HbA1c values > or =9% and <9% defined subjects with poorly and better-controlled diabetes, respectively.
  
  
  RESULTS
  All clinical parameters improved after therapy (P <0.05). No significant differences were observed between treatment groups for clinical and metabolic parameters at any time (P >0.05). There were no changes in the HbA1c levels after therapy (P >0.05). No subject reported any adverse effects during the study. Individuals with better-controlled diabetes achieved a lower mean CAL at 6 months post-therapy, when FMSRP and PMSRP were evaluated together (P <0.05).
  
  
  CONCLUSIONS
  FMSRP and PMSRP were equally effective in treating chronic periodontitis in subjects with type 2 diabetes, without significant improvements in the glycemic control at 3 and 6 months. Considering the periodontal therapy as a whole (FMSRP plus PMSRP), subjects with better-controlled diabetes exhibited a benefit in CAL at 6 months compared to subjects with poorly controlled disease.
