title: [Effects of dental health awareness and behaviours on the glycemic metabolic characteristics and periodontal disease of patients with type 2 diabetic].
abstract: OBJECTIVE
  To analyze the effects of dental health awareness and behaviours on the relationship between glycemic metabolic characteristics and periodontal disease of type 2 diabetic patients.
  
  
  METHODS
  In the study, 83 subjects with type 2 diabetes mellitus were recruited. The clinical periodontal indexes, such as pocket probing depth (PPD), 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) were made, glucose assay tested, and the structured questionnaire interview conducted evaluationg the knowledge, attitude and practice (KAP) about periodontal health.
  
  
  RESULTS
  The prevalence of moderate and severe periodontitis was 67.5%, compared with mild periodontitis, whose severities were affected by the higher level of HbA1C (≥8.0%) (OR 54.1-143.1), followed by using glycemic drug (OR=12.9-44.6), stress (OR=16.9-29.6), and the dissatisfaction with diabetic therapy (OR=16.9-18.0) et al. Meanwhile the attachment loss conditions were also correlated with the poor periodontal knowledge level(OR=3.4),older age(OR=1.1),and misjudgement of gingival inflammation (OR=13.3) et al. On the other hand, individuals with moderate and severe periodontitis, having bad teeth brushing effects and knowing about dental plaque inadequately, had a significantly higher risk for the poorly controlled glycemic results (HbA1C≥8.0%), and the OR was 8.61, 8.07, and 7.49 respectively.
  
  
  CONCLUSIONS
  In patients with type 2 diabetes the severity of periodontal disease and the glycemic metabolic level (HbA1C) have a definite bidirectional adverse interrelationship, which is affected by the dental health awareness and behaviours.
