title: Periodontitis as a risk factor in non-diabetic patients with coronary artery disease.
abstract: BACKGROUND
  Coronary artery disease (CAD) is responsible for many mortality across the world, especially in our country.The conventional risk factors for atherosclerosis are well understood, but they can account for only about50% to 70% of atherosclerotic events in the general population. The aim of this study was to investigate relationships between prevalent coronary artery disease(CAD) and clinical periodontal disease in patients with angiographic ally proven coronary artery disease.
  
  
  METHODS
  152 consecutive patients with angiographically proven coronary artery disease will be included in this study, who received a complete periodontal examination during visit.
  
  
  RESULTS
  Patients with normal coronary, average plaque index (1.6±1.02) Index of bleeding (1.51±0.92),mean adhesion level (3.57±1.18). But patients with coronary artery disease, the mean plaque index (2.46±0.62) Index of bleeding (1.86±0.92), mean adhesion level (4.13±1.45). This differences are statistically significant. (P <0.05) In this study, average depth of probe entrance on the surface of teeth has had little relation with cardiovascular disease (p=0.051).
  
  
  CONCLUSIONS
  According to the results of this study, in peoples over 40 years, who had coronary artery disease proved by coronary angiography, gingival inflammation (periodentitis) has a significant relation as a risk factor.
