Abstract
OBJECTIVES: We investigated the association among diagnosed osteoporosis, osteoporotic fractures, and carotid artery calcification (CAC) detected on panoramic radiographs. Additionally, we assessed whether osteoporosis or fractures could be predicted by an incidental finding of CAC.
STUDY DESIGN: One thousand twenty-one patients participated in this study. Patients completed a structured questionnaire. Logistic regression analysis adjusted for covariates was used to calculate the odds ratio (95% confidence interval) for diagnosed osteoporosis or fractures according to the presence of CAC. Extended receiver operating characteristic (ROC) curve analysis was used to clarify whether osteoporosis or fractures were predicted by the detection of CAC.
RESULTS: The odds ratios for diagnosed osteoporosis or fracture associated with CAC were 1.82 (1.02-3.24) and 0.77 (0.33-1.77), respectively. The areas under the ROC curves for identifying patients with osteoporosis or fractures according to the detection of CAC were 0.54 and 0.50, respectively.
CONCLUSIONS: CAC may not be useful for identifying Japanese individuals with osteoporosis or those at risk of fracture, although the presence of CAC was significantly associated with a history of diagnosed osteoporosis without osteoporotic fractures.
