Study on the Correlation Between Periodontitis and Atherosclerosis Based on CTA of Head and Neck
Objectives This study aims to investigate the relationship between the severity of periodontitis and atherosclerosis of head and neck based on CTA examination,so as to provide a reference for the prevention of cerebrovascular disease.Methods A total of 87 patients who underwent head and neck CTA examinations at a hospital from January 1,2022,to July 31,2023,and underwent periodontal examinations within one week were included in the study.According to the diagnostic criteria of periodontitis,the 87 patients were divided into four groups:no periodontitis group(19 cases),mild periodontitis group(24 cases),moderate periodontitis group(23 cases)and severe periodontitis group(21 cases).The sex,age,different degree of head and carotid artery stenosis,number of stenosis segments and plaque type of the four cases were recorded and compared in detail.Results There were no significant differences in gender and age among the four groups(P＞0.05).The proportion of vascular stenosis in the group with periodontitis(95.8％～100％)was higher than that in the group without periodontitis(42.1％).The severity of periodontitis correlates positively with both the proportion and severity of vascular stenosis,with statistical significance(P＜0.05).The number of narrow vascular segments in the group with periodontitis(96～170 segments)was significantly more than that in the group without periodontitis(26 segments).There is a positive correlation between the severity of periodontitis and the number of narrow vascular segments(P＜0.05).There was no significant difference in the types of vascular plaques among the four groups(P＞0.05).There was a statistically significant difference in the total number of plaques(range:49 to 226),with a positive correlation observed between the severity of periodontitis and the number of plaques(P＜0.05).Conclusions There is a close relationship between periodontitis and the degree of head and carotid artery lesions.Active treatment of periodontitis has important clinical significance in preventing cerebrovascular disease.
