Abstract
Aim: Detection of calcified carotid atheroma (CCA) has an important role in reducing the incidence of Cerebro Vascular Accident (CVA). The aim of this study was to evaluate efficacy of panoramic digital radiography in detecting atherosclerosis. Methods: It is descriptive-analytical diagnostic study. The people (22 to 62 years old) were referred to a radiology clinic to perform panoramic radiography for diagnosis of CCA. Individuals who were suspected were introduced to the radiology department of dental school to undergo ultrasound evaluation to CCA. For the 41 patients (55 sides), ultrasound was performed. For data analysis, the Chi-square and Fisher's exact test were used. Results: The prevalence of CCA was 2.43%. The PPV of digital panoramic was 45.5%. There was no significant relationship between age (P = 0.14) and sex (P = 0.539) and PPV of digital panoramic. The PPV of digital panoramic was significantly associated with hypertension (P = 0.032). Conclusion: It seems that panoramic can be used to screen patients with a history of hypertension for atherosclerosis.

The aim of this study was to evaluate the efficacy of digital panoramic radiography for detection of calcified carotid atheroma
1682 digital panoramic radiographs were evaluated and calcified carotid atheroma was observed in 2.43% of cases; so the study was conducted on 41 patients (16 males and 27 females) aged 22 - 67 years old with calcified carotid atheromas detected in digital panoramic radiographs
The prevalence of calcified carotid atheromas on panoramic digital radiography in this study was 2.43% which was somewhat similar to some other studies, e.g. 2% in Friedlander et al in 1981 [19], 3% in Friedlander AH study in 1994 [22], 3% - 5% in Friedlander AH in 2001 [23], 2% - 5% in Tarim Ertas et al [9], 5% in Ohbata et al [24], 3.6% in Carter et al study [25]
