Abstract
BackgroundThe aim of the present study was to analyze the epidemiological data of digital panoramic radiographs revealing suggestive images of carotid artery calcifications (CAC) from a Northeast Brazilian population.Material and MethodsA cross-sectional retrospective study was conducted with 2,500 digital panoramic radiographs obtained from a single imaging reference center in Northeast Brazil. Images from individuals of both sexes and older than 18 years were included and those that did not cover the region of cervical vertebrae or presented low radiographic quality were excluded. Data were analyzed regarding prevalence, location (bilateral, right or left), sex, and age using the Chi-square test at the significance level of 5%.ResultsAn amount of 96 (4%) patients presented suggestive images of CAC. The female sex (p=0.003) and individuals aged up to 70 years (p=0.002) were statically significant. 40.4% were found bilaterally, 37.6% on the right side (p<0.001) and 22% on the left side.ConclusionsIn conclusion, this study showed a low prevalence of suggestive images of CAC in digital panoramic radiographs from a Northeast Brazilian population. It was observed a higher prevalence of CAC associated with female sex, older patients, and right side location. Key words:Atherosclerosis, carotid artery, digital panoramic radiograph, prevalence.
Highlights
Coronary artery disease is considered a major cause of worldwide morbidity and mortality [1], being a multifactorial disorder in which multiple genetic variants are combined with several environmental risk factors and deleterious lifestyles [2]
Radiographs suggesting CAC were observed in individuals with age ranging from 25 to 89 years
Atherosclerotic plaques in carotid arteries have been extensively studied in the field of Medicine and Dentistry
Summary
Coronary artery disease is considered a major cause of worldwide morbidity and mortality [1], being a multifactorial disorder in which multiple genetic variants are combined with several environmental risk factors and deleterious lifestyles [2]. Carotid artery calcifications (CAC) can be visualized on panoramic radiographs, imaging exams that are routinely used in the evaluation of patients with dental issues [5]. A limited number of studies regarding CAC prevalence on digital panoramic radiographs from South America have been published to date.
