Abstract
OBJECTIVE: To evaluate if the presence of periodontitis is associated with carotid arterial calcifications diagnosed on panoramic radiographs in an elderly population. MATERIALS AND METHODS: Study individuals were randomly selected from the Swedish civil registration database representing the aging population (60-96 years) in Karlskrona, Sweden. Bleeding on probing (BOP) and the deepest probing measurement at each tooth were registered. The proportions of teeth with a probing depth ≥ 5 mm and the proportion of teeth with bleeding on probing were calculated. Analog panoramic radiographs were taken and the proportion of sites with a distance ≥ 5 mm between the alveolar bone level and the cement-enamel junction (CEJ) were assessed. A diagnosis of periodontitis was declared if a distance between the alveolar bone level and the CEJ ≥ 5 mm could be identified from the panoramic radiographs at > 10% of sites, probing depth of ≥ 5 mm at one tooth or more and with BOP at > 20% of teeth. RESULTS: Readable radiographs were obtained from 499 individuals. Carotid calcification was identified in 39.1%. Individuals were diagnosed with periodontitis in 18.4%. Data analysis demonstrated that individuals with periodontitis had a higher prevalence of carotid calcifications (Pearson χ(2) = 4.05 p < 0.05) and with a likelihood of 1.5 (95% CI = 1.0, 2.3, p < 0.05). CONCLUSIONS: Data analysis demonstrated a significant association between periodontitis and carotid calcification.
