title: [Effect of community periodontal care intervention on periodontal health and glycemic control in type 2 diabetic patients with chronic periodontitis].
abstract: OBJECTIVE
  To evaluate the effectiveness of community periodontal care intervention in type 2 diabetic patients with chronic periodontitis who participated in community non-communicable diseases management service.
  
  
  METHODS
  The randomized controlled and blinded community trial with a duration of six months was designed to compare effects of "periodontal initial therapy" on group I(22 cases), of "professional mechanical tooth cleaning (PMTC), i.e. coronal scaling" on group II(19 cases)and of "non-clinical therapy" on the control group(25 cases). The clinical periodontal indexes, such as probing depth (PD), attachment loss (AL), modified bleeding index (mBI), plaque index (PLI) were obtained with a Williams type periodontal probe; Laboratory examinations including glycosylated haemoglobin A1(HbA1C), glucose assay, were conducted.
  
  
  RESULTS
  The reductions of PD in groups I and II were 0.71 and 0.70 mm, respectively, which was more significant than in control group (0.20 mm); the reductions of AL in groups I, II, and control group were 0.86, 0.57, and 0.03 mm, respectively, which showed significance in all the three groups. The subjects of groups I and II had 0.56% and 1.01% reductions of HbA1C respectively, and the significance was observed in group II. In addition, the improvement of HbA1C values in group II was highly correlated with the decrease in gingivitis (r=0.51, P=0.03).
  
  
  CONCLUSIONS
  The community periodontal care approaches implemented in the community health service centers have significantly improved periodontal health as well as reduced glycemic level, which could be regarded as basic health care strategies for the patients with diabetes.
