Abstract

The purpose of this study is to investigate the relationship between the state of periodontal disease and the severity of atherosclerosis. The subjects were 71 hypertensive patients (aged 61.1 ± 9.6 years). The mean of the probing depth (PD) at all measured sites, the mean PD at deepest sites each tooth and percentage of sites with bleeding on probing (BOP) were 4.0 ± 1.0 mm, 6.2 ± 2.2 mm, and 43.6 ± 29.4% respectively, indicating markedly advanced periodontal disease. The pulse wave velocity (PWV) was significantly higher (p < 0.05, t-test) in the high BOP group (BOP ≥ 40%) than in the low BOP group (BOP < 40%), and was higher in the large PD group (PD ≥ 4 mm) than in the small PD group (PD < 4 mm). Increased PWV values indicate an increased arterial stiffness. Therefore, these findings suggest that advanced periodontal disease in hypertensive patients is associated with increased atherosclerosis risk.
