Análise da ocorrência de imagens sugestivas de calcificações da artéria carótida em radiografias panorâmicas

Abstract

The purpose of this study was to evaluate images suggestive of atheroma in panoramic radiographies and to verify their predilection related to gender, age and uni or bilateral localization. It was also aimed to aware dentists to better analyze panoramic radiographies. Two evaluators analyzed 10,000 panoramic radiographies. Data were submitted to statistical analysis (Chi-squared test, Student’s t test, ANOVA; p<0.05). Atheromas were found in 74 radiographies. Men aged from 51 to 60 years and unilateral localization (left side) of the images had the greatest incidences. These results were not statistically significant in relation to these predisposing factors. Nevertheless, images suggestive of carotid artery calcifications were found in patients from16 to 84 years old, which emphasizes the need for an accurate observation of panoramic radiographies. The pre-vertebral region is not usually analyzed by dentists. However, since the anatomy of this region is known and the arterial lesions are almost impossible to be detected until they led to morbidity and mortality, it is important to explore the alternative means to the early diagnosis of this condition. Therefore, knowledge is required to identify atherosclerosis in panoramic radiographies and to confirm it by other exams. It contributes for a holistic approach to the patient and to a resulting decrease in the incident of cerebrovascular accidents.
