GARBELOTTI-JUNIOR, S et al. Prevalence of Atherosclerotic Carotid Lesions on Panoramic Radiography and Relationship with Cardiovascular Risk Factors in Brazilians. Int. J. Morphol. [online]. 2020, vol.38, n.6, pp.1560-1565. ISSN 0717-9502.

Although panoramic radiography is not an initial diagnostic test for detecting carotid atherosclerosis, we cannot ignore its value in viewing these lesions as incidental findings that can be great allies in early diagnosis and prevention of serious vascular events. The aim was to evaluate the prevalence of calcifications in the bifurcation of the carotid artery on routine panoramic radiographs as a diagnostic principle, as well as its relationship with cardiovascular risk factors in Brazilians. We analyzed 449 panoramic radiography exams from the database of the Department of Radiology of the Faculty of Dentistry of Piracicaba, UNICAMP, São Paulo, Brazil. After obtaining blood pressure measurements and information on smoking and systemic diseases, the researcher observed on the panoramic radiograph, the presence or absence of the radiopaque mass in the regions of the cervical vertebrae C3-C4. In the case of a suggestive image of atheroma, an anteroposterior radiography was performed to confirm the diagnosis. The Chi-square test of normal distribution for independent and random samples with a 95 % confidence interval was applied to the data. Confirmation of carotid calcifications occurred in 8.5 % of the study population (38 cases). We did not find any relationship between the presence of calcifications with smoking, sex or previous family history. However, 49.1 % of cases occurred above sixty years old and there was a significant relationship with hypertension (P = 0.006). The greatest risk was presented in elderly and hypertensive patients, so we highlight the importance of a thorough observation by the dentist of panoramic radiographs to detect any alteration of the normal anatomy and in the positive case, proceed with the referral as soon as possible for a conclusive diagnosis by a specialist, being able to thus assist in the prevention of severe vascular episodes.
