Caries risk and periodontitis in patients with coronary artery disease

There is considerable variation in studies on the oral health of patients with coronary artery disease (CAD). The aims of this investigation are to study the caries risk profile using the Cariogram computer program and the periodontal disease severity in patients with CAD.

A total of 127 participants (54 test and 73 control) were included. Participants were asked about their general health and daily habits. Clinical examinations, radiographs, and salivary sampling were performed. Cariologic data were entered into the computer program for risk-profile illustration. The onset of CAD conditions was also documented.

Compared with controls, participants with CAD consumed less sugar, used fluoride toothpaste less frequently, and had significantly less favorable periodontal parameters (P <0.005). Generally, differences in cariologic parameters between the two groups were not significant. Significantly more participants with CAD exhibited low salivary-secretion rates than controls. The actual chance (percentage) of avoiding new cavities according to the Cariogram was low in the test and control groups (31% and 40%, respectively; P <0.05). Only gingival recession was correlated with the onset of CAD.

Test and control groups had a relatively high caries risk. More severe periodontal disease was observed in participants with CAD.
