Abstract:
Objective To detect the correlation between the periodontal bone loss and carotid calcifications by using MSCT.Methods Imaging materials of 270 patients who were suspected atherosclerosis and underwent MSCT were retrospectively studied.According to the score of carotid calcification,the patients were divided into three groups:slight calcification group (carotid calcification score <100),severe calcification group (carotid calcification score ≥100),and normal control group (carotid calcification score=0).The original images were post-processed with volume rendering(VR),multi planar reformation(MPR),curved planar reformation(CPR)and maximum intensity projection (MIP)by using EBW4.5 workstation,and then the residual teeth number and the periodontal bone loss teeth were recorded in different groups.Results On MSCT,the carotid calcification score and the number of periodontal bone loss were displayed clearly.The number of the periodontal bone loss teeth in the calcification groups were significantly higher than those in the normal control group(P<0.01).Furthermore,the number of the periodontal bone loss teeth was positively correlated with the severity of carotid calcification.Conclusion The periodontal bone loss is highly correlated with the severity of the carotid calcification.The volume reconstruction technique of MSCT is a non-invasive diagnostic testing to detect the periodontal desease and to quantify carotid calcifications.
