title: Long-term effect of periodontal surgery on oral health and metabolic control of diabetics.
abstract: OBJECTIVE
  The objective of this study was to evaluate impact of periodontal surgery on periodontal health and on glycaemia control of type 1 and type 2 (T1DM; T2DM) diabetics with severe periodontitis, during 12 months follow-up, in comparison with non-diabetic controls.
  
  
  METHODS
  A total of 23 T1DM and 10 T2DM patients with respective number of matched non-diabetics were examined prior to, and 3, 6 and 12 months after periodontal surgery. Glycosylated haemoglobin (HbA1c) reflected control of DM. Periodontal parameters were oral debris (DI-S), probing pocket depth (PPD), clinical attachment loss (CAL) and bleeding on probing (BOP).
  
  
  RESULTS
  Periodontal status in all diabetics improved after 3 months and remained so during follow-up: mean (SD) DI-S > 1 (T1DM 1.1(0.5)/0.9(0.7); T2DM 1.2(0.4)/0.8(0.4)), PPD >5 mm (T1DM 35.1(32.2)/5.1(7.8); T2DM 46.3(24.2)/13.0(10.9)), CAL ≥6 mm (T1DM 44.4(37.0)/24.52(27.2)); mean % BOP >50 % (T1DM 57.1(25.1)/22.8(20.8)), T2DM 59.4(20.8)/18.9(15.7)), p < 0.05. Mean HbA1c values decreased in T2DM patients after 3 months and remained stable during follow-up. No improvement of glycaemia control was observed in T1DM patients. Positive correlation between mean HbA1c and CAL changes was observed (r = 0.842, p < 0.05). Mean changes of periodontal parameters did not differ between diabetics and controls.
  
  
  CONCLUSIONS
  Periodontal surgery improved significantly periodontal status of all patients and metabolic control of T2DM patients.
  
  
  CONCLUSIONS
  Research findings concerning long-term effect of periodontal surgery among patients with diabetes mellitus are scarce. We found that surgical periodontal treatment positively affects periodontal health of all diabetics and improves metabolic control of type 2 DM. There is a positive correlation between clinical attachment loss and glycosylated haemoglobin levels.
