Carotid calcified lesions present on panoramic images are arteriosclerotic involving vascular lesions. Arteriosclerosis caused by cerebrovascular disease, which is the fourth leading cause of death in Japan, and arteriosclerotic heart disease account for the majority of sudden deaths in Japan. We believe that panoramic radiographic images can be used to determine the presence or absence of carotid calcification, explain the possible pathogenesis of vascular lesions, and encourage individuals to consult physicians in order to prevent the onset of arteriosclerosis. Atherosclerosis typically affects the carotid artery, which may develop into calcifications. Panoramic images can be used to observe calcification of the affected carotid area. From examinations, we can deduce if the calcification of the carotid artery is related to secondary vascular lesions or not. This article explains the importance of diagnosing carotid calcified lesions from panoramic images from our previous studies. Furthermore, we employ a larger sample size for examinations, and perform suitable analysis to demonstrate the relationship between carotid calcification and the risk factors for arteriosclerosis. As a result, we propose a diagnostic imaging system which can accurately diagnose and predict carotid calcifications.
