The correlation between periodontal diseases and carotid arteries atherosclerosis by three-dimensional reconstruction technique of multi-slice spiral CT in elderly people / 中华老年医学杂志

ABSTRACT

Objective To explore the possible correlation between periodontal disease and carotid arteries atherosclerosis in old people,and to study the diagnostic value for periodontal disease using three-dimensional (3D) reconstruction technique of multi-slice spiral CT (MSCT).Methods Patients underwent multi-detector row CT angiography with carotid arteries atherosclerosis (control group) and without carotid arteries atherosclerosis (case group) were evaluated with the stereoscopic configuration of teeth,and the number of decayed teeth and lost teeth were recorded.Results Bythe 3D reconstruction technique,the number of decayed teeth and lost teeth between two groups were significantly different (P＜0.05).The number of dental integrity patients was higher in control group (19 cases) than in case group(7 cases).The mean of dental caries was higher in control group(7.3±3.0) than in case group(6.0±2.1).The mean of hypodontia was higher in control group(45 cases) than in case group(39 cases) (P＜0.05).Conclusions The 3D reconstruction technique of MSCT is a new method to display the stereoscopic configuration of teeth.The periodontal disease is significantly related with carotid arteries atherosclerosis in old people.
