ABSTRACT

Objective To explore the association between the number of teeth and the severity of coronary artery disease.Methods The severity of coronary artery disease in 156 patients with coronary heart disease or suspected coronary heart disease were determined by coronary angiography.All the patients were catagorized into the severe lesions group(n=74) and the mild lesions group(n=82) according to their coronary score.The number of teeth and other potential risk factors for coronary heart disease in each patient were investigated.Results There were significant differences in age(65.29?9.23 yrs vs 62.04?10.23 yrs,P=0.04),comorbidity of diabetes(32.79% vs 16.84%,P=0.021),serum levels of total cholesterol(4.95?0.94 mmol/L vs 4.65?0.90 mmol/L,P=0.042),low density lipoprotein(3.28?0.74 mmol/L vs 2.90?0.78 mmol/L,P=0.0020),high density lipoprotein(1.03?0.29 mmol/L vs 1.16?0.31 mmol/L,P=0.009) and C-reactive protein(12.66?14.64 mg/L vs 5.28?5.96 mg/L,P
