Periodontitis did not even appear to be associated with atherosclerosis.

Some research has suggested that periodontal inflammation contributes to cardiovascular disease, but the apparent association has also been attributed to tobacco smoking which is a causal factor common to both conditions. Some investigators have strongly recommended studies in life-long non-smokers. In participants from the ARIC study, a sub-sample of 269 subjects was selected; these had received dental examinations and a cardiac CT scan for coronary artery calcification (CAC).
Subjects with attachment loss of 3 mm+ at 10% or more of periodontal sites were older and had smoked significantly more than those with <10% of sites affected. Subjects with a CAC score of 100+ were older, and more likely to be male, smokers, and on antihypertensive medication, and had a higher waist-to-hip ratio. Multiple logistic regression with these and other cardiac risk factors as covariates gave a non-significant odds ratio of 1.51 (95% CIs: 0.54, 4.23) for the association between periodontitis and CAC. Even if an association could be identified, the path of causality would also need to be demonstrated.
