“…Notwithstanding, even though panoramic radiographs are not the most indicated exams to evaluate the presence of CCAA, they are extremely useful for early detection in asymptomatic patients (25). Furthermore, this research had a greater number of patients (180) than the majority of published articles (10,16) and all panoramic radiographs were digital, which has a superior quality when compared to conventional ones (9,18,22). Moreover, all patients were submitted to 3D conformal RT for treatment of a SCC of the head and neck with carotid arteries included in the radiation field - making it a more homogeneous group.…”

BackgroundThe aims of this study were to verify if head and neck radiotherapy (RT) is able to induce calcified carotid artery atheroma (CCAA) in a large head and neck cancer (HNC) population and also to compare the socio-demographic and clinical findings of patients with and without CCAA detected on panoramic radiographs.Material and MethodsPanoramic radiographs taken before and after head and neck radiotherapy (RT) of 180 HNC patients were selected and analyzed in order to identify the presence of CCAA. In addition, CCAA presence or absence on panoramic radiographs were compared and correlated with clinicopathological findings.ResultsA high overall prevalence of CCAA was found on panoramic radiographs (63 out of 180 = 35%) of HNC patients. No significant difference of CCAA before and after RT was observed. There were also no differences between groups (with and without CCAA) regarding age, gender, tobacco and alcohol use, arterial hypertension, diabetes mellitus, acute myocardial infarction, hypercholesterolemia, tumor location, clinical stage of disease and RT dose. However, there was a greater prevalence of strokes in patients with CCAA (p<0.05).ConclusionsAlthough CCAA were frequently found in panoramic radiographs of patients with HNC, RT seems not to alter the prevalence of these calcifications. Key words:Head and neck cancer, radiotherapy, carotid artery diseases, panoramic radiography.

“…Many studies have suggested that the direct effect of RT to the carotid arteries is able to induce/accelerate atherosclerosis (16,20-22). In the current research, most of the patients with CCAA in their panoramic radiograph after RT also presented this alteration before treatment.…”

“…Their location and appearance differentiated them from anatomical radiopacities (the hyoid bone, epiglottis, and stylohyoid and stylomandibular ligaments) and pathologic entities (sialolithiasis, phleboliths, and calcifi ed lymph nodes) that variably appear contiguous to this region. 3,11 The panoramic radiographs of patients over age 50 with type II diabetes mellitus showed a higher prevalence (43%) of calcifi ed atherosclerotic lesions than those of patients of similar age without diabetes (3.2%). The difference in the prevalence of CCAA between these groups might have arisen because of the signifi cantly greater number of risk factors (fasting blood sugar, cholesterol, and serum triglycerides) in the diabetic patients, as these factors are known to be associated with the development of atherosclerosis.…”

Objectives.To determine the prevalence of calcifi ed carotid artery atheromas (CCAAs) in panoramic radiographs of patients with type 2 diabetes mellitus. Methods. The panoramic radiographs of 751 patients referred to the Oromaxillofacial Radiology Department of the Dental Faculty of Shahid Sadoughi University for routine dental treatment were evaluated for CCAAs. In this descriptive study, the data for each patient were recorded on a questionnaire based on the medical history, an interview, and a physical examination. The prevalence of CCAA was compared statistically to determine the signifi cance of atherogenic risk factors. Results. Of the 751 patients studied, 75 showed signs of CCAAs in their radiographs (10%). Fifty-fi ve of the 128 diabetics patients had CCAAs compared with only 20 of 623 nondiabetic patients (43% vs. 3.2%; P < 0.001). The prevalence of CCAA in 180 patients over 50 years of age was 28.9%, while the prevalence was only 4% in patients under 50 years. The prevalence of CCAAs on the radiographs of nondiabetic patients over age 50 was 11.8% versus 47.1% in diabetics over age 50 (P < 0.001). Conclusion. Individuals over age 50 and patients with diabetes mellitus have a greater prevalence of CCAAs in their panoramic radiographs than younger individuals and nondiabetic patients.

“…In 1981, Friedlander and Lande (10) were the first to describe the panoramic X-Ray as a supplementary means for identifying patients at risk of suffering from strokes. By assessing a thousand panoramic X-Rays of male individuals aged between 50 and 75, they identified calcifications in the region of the bifurcation of the carotid artery in 2% of cases.…”

“…By assessing a thousand panoramic X-Rays of male individuals aged between 50 and 75, they identified calcifications in the region of the bifurcation of the carotid artery in 2% of cases. Those images showed that 88% were calcifications of the carotid artery and the remaining 12% were calcified lymph nodes or salivary calculi (10). …”

Objective: To assess the possibility of Dentists being able to screen patients with higher risk of vascular diseases. Material: Kodak 8000C Orthopantomographer, eco-Doppler Logiq-500 General Electric at the Lisbon Hospital Particular. Methods: Assessment of orthopantomographies made to 142 patients aged 50 or more, as well as the existing risk factors. Conduction of carotid eco-Doppler to patients who appear to have calcified plaques of the atheroma. Results: Strong dependence between dichotomised age and having the pathology (p = 0.02).Smokers are twice more likely to present plaques (OR= 2). Being hypertensive increases in about 1.4 the likelihood of having a stroke (OR= 1.4). Of the 27 individuals who presented calcifications in the Orthopantomography, they were all submitted to an eco-Doppler and 21 had the pathology confirmed. 27 individuals, who did not show any plaques in the Orthopantomography, were randomly selected to be the control group. They were submitted to an eco-Doppler. And 23 confirmed the non-existence of plaques. Conclusions: Orthopantomography used for assessing the oral cavity reveals more information which should be the object of the Dentist’s attention. Key words:Orthopantomography, atheroma, stroke.
