Infectious Dental Diseases in Patients with Coronary Artery Disease: An Orthopantomographic Case–Control Study

Date
Purpose: To investigate a potential association between coronary artery disease (CAD) and a variety of radiographically detectable infectious dental diseases, a hospital-based prospective case–control study was conducted in Kuwait.Materials and Methods: Eighty-eight consecutive patients with a first attack of unstable angina pectoris or acute myocardial infarction were enrolled as cases and were matched on the basis of age, sex and nationality with control patients who were known not to have CAD. The severity and extent of periodontal bone loss and other radiographic signs of infection in both cases and controls were analyzed with orthopantomograms.Results: More cases than controls had teeth needing extraction (p = 0.043), periapical lesions (p = 0.028), molars with furcation lesions (p p = 0.001) and teeth with angular (vertical) bone loss (p p p = 0.008).Conclusions: In summary, there was a significant association between radiographically diagnosed periodontal diseases and CAD. These results should not be regarded as indicating a causal relationship, especially given that the diagnosis of periodontitis was based only on a radiographic examination. The true impact of oral infections on CAD should be examined in a large prospective clinical and interventional study.
