Correlation of periodontal diseases with intracranial aneurysm formation: novel predictive indicators

Abstract

Abstract Background We investigated whether periodontal diseases, specifically, periodontitis and gingivitis, could be risk factors of the incidence of intracranial aneurysms (IAs). Methods We performed a case–control study to compare the differences in the periodontal disease parameters of 281 cases that were divided into the IAs group and non-IAs group. All cases underwent complete radiographic examination for IAs and examination for periodontal health. Results Comparing with those in the non-IAs group, the cases in the IAs group were older (53.95 ± 8.56 vs 47.79 ± 12.33, p 50 years) and hypertension were predictive risk factors of aneurysm formation (odds ratio [OR] 1.047, 95% confidence interval [95% CI] 1.022–1.073, p 1.1 and plaque index > 1.5) had the correlation with IAs formation (p = 0.007 and p < 0.001). Conclusion Severe gingivitis or periodontitis, combining with hypertension, is significantly associated with the incidence of IAs.
