Regarding BL-max, compared with those in the first quartile, ORs (95% CIs) of those in the second, third, and fourth quartiles were 1.15 (0.65–2.30), 0.65 (0.32–1.35), and 1.57 (0.81–3.01), respectively.

In the multivariate model, compared to those with regular dental visits, the odds ratio (OR) (95% confidence intervals ) of atherosclerosis among those with the absence of regular dental visits was 2.16 (1.03–4.49).

Of 602 participants, 117 had atherosclerosis. The primary outcome was atherosclerosis, defined as maximum carotid intima-media thickness ≥1.1 mm or confirmation of atheromatous plaque. Exposure variables were regular dental visits periodontitis, defined as radiographic alveolar bone loss (BL) the Centers for Disease Control/American Academy of Periodontology (CDC/AAP) classification and number of remaining teeth. The participants of this cross-sectional study included community dwellers aged ≥55 years and residing in Ohasama.

Backgroundįew studies have examined the association between regular dental visits, periodontitis, tooth loss, and atherosclerosis in community dwellers in Japan. We aimed to explore the association between regular dental visits and atherosclerosis and between periodontitis, number of remaining teeth, and atherosclerosis among community dwellers in Japan.
