Atherosclerosis is a chronic inflammatory disease that can cause death and physical and/or
mental disabilities. It represents a serious public health problem owing to the high healthcare costs
involved in rehabilitating patients. Among the different methods available for diagnosing
atherosclerotic disease, color Doppler examination may be considered the “gold standard.” On
the other hand, panoramic radiography of the jaws (PRJ) is a diagnostic resource commonly
used by dentists, and the obtained images allow examining other structures apart from the maxilla
and the mandible.
Aim: To evaluate the sensitivity and accuracy of panoramic radiography in
identifying calcified carotid atheroma, and compare the results to those obtained with color Doppler
Methods: Forty-two cervical regions were evaluated in panoramic radiographs
and color Doppler scans. The kappa test (p < 0.05) was used to assess agreement between the
examinations. Data were tested for sensitivity, specificity and negative predictive value, as well as
positive and negative likelihood ratios.
Results: The kappa value was 0.11. The sensitivity and
specificity of PRJ were 73.9 and 36.8%, respectively, and the positive and negative likelihood
ratios were 1.2 and 0.7, respectively.
Conclusions: Although a low correlation between PRJ
and color Doppler examination was observed, as shown by the kappa test, the sensitivity of PRJ
in identifying calcified carotid atheroma was considered acceptable.
