Atherosclerosis is a chronic inflammatory process that affects the arteries of different vascular beds. The most common site is the origin of the internal carotid. It is estimated that 50% of strokes are caused by atherosclerotic plaques. Panoramic radiographs are routine and inexpensive radiographic studies that allow us to observe flatly dental structures, maxillary and mandibular. Friendlander in 1981 published for the first time the possibility of identifying through panoramic radiographs atherosclerotic plaques calcified at this bifurcation giving importance of this study the opportunity for early detection of this disease.Objective: To determine the prevalence of carotid calcifications in 316 patients admitted to clinic admission of the Escuela Nacional de Estudios Superiores, Unidad León, Universidad Nacional Autónoma de México (UNAM).Results: Consistent findings were obtained with atheroma calcified carotid in 7 patients with which it is concluded on the importance of training of imaging diagnosis undergraduates for early diagnosis and prevention of stroke in patients at risk of stroke.
