AP risk in teeth that had undergone periodontal treatment was over 5 times higher than for teeth without periodontal disease. This underscores the importance of maintaining a healthy periodontium. There was no evidence of a
Apical periodontitis (AP) is an inflammatory process related to the presence of infection caused by intraradicular microorganisms. Many factors have been postulated to increase the risk of developing AP, including systemic diseases, poor oral health, low socioeconomic status, inadequate root fillings or coronal restorations, and the presence of caries. Some studies suggest that endodontic infection can adversely affect periodontal health, but the effect of periodontal disease on the development
One hundred ninety-four teeth with adequate root canal filling, adequate coronal restorations, and no AP were evaluated. Patient records included age, sex, history of diabetes mellitus, smoking status, hypertension, and immunodeficiency disorders. Patients were divided into 2 groups based on their periodontal status, whether healthy or receiving treatment for periodontal disease. The incidence of AP was determined after an observation period of at least 2 years.
AP was found in 3 teeth (3%) of the nonperiodontal samples and in 13 teeth (14%) of the periodontal samples. There was no significant relationship between AP status and patient’s age, sex, smoking habits, diabetes mellitus, or immunodeficiency disorders.
Statistical analysis revealed that hypertension and periodontal status were significantly related to AP development. Multivariate logistic regressions for hypertension revealed periodontal status as the only factor significantly related to AP
AP was significantly more common among patients who had undergone periodontal treatment than in patients with a healthy periodontal status. Even in patients who had completed adequate periodontal treatment the risk of developing AP was increased.
