Correlation between Cone Beam CT Data and the Levels of Inflammatory Markers in Odontogenic Respiratory Comorbidity

Aim. In this study, the authors set out to find the correlation between the data of cone beam computed tomography (CBCT) and the levels of inflammatory markers in patients with chronic generalised periodontitis (CGP), both without somatic pathology and with bronchiectasis.Materials and methods. The study included 90 CGP patients and 40 somatically healthy individuals with intact periodontium. CGP patients were divided into two groups: CGP patients without somatic pathology (n = 40) and CGP patients with bronchiectasis (n = 50). Using ELISA, the authors determined the level of the following inflammatory markers in oral fluid: transforming growth factor beta 1 (Tgfß-1), interleukin -8 (IL-8), lactoferrin (LF) and C-reactive protein (CRP).Results. The analysis of CBCT data and the levels of inflammatory markers (Tgfß-1, LF, IL-8 and CRP) revealed that more pronounced changes in their values were observed in CGP patients with bronchiectasis. In addition, the revealed correlations between CBCT data and the levels of inflammatory markers in CGP patients without somatic pathology and CGP patients with bronchiectasis indicate a relation between the severity of inflammatory reaction and the clinical manifestations of CGP. Furthermore, this correlation is stronger in CGP patients with comorbid pathology than in CGP patients without somatic pathology.Conclusion. The presence of comorbid pathology in the form of bronchiectasis in CGP patients has a negative impact on the periodontium, which should be considered when managing patients

Prognosis of progression of chronic generalised periodontitis in patients with bronchiectatic disease

Aim. To analyse the parameters of dental indices and the level of markers of infl ammation and oxidative stress in patients with chronic generalised periodontitis (CGP) with bronchiectatic disease and to develop a mathematical model for assessing the risk of CGP progression in patients with bronchiectatic disease.Materials and methods. A total of 70 patients with mild and moderate CGP were examined, which were divided into the following groups: patients with CGP without general somatic pathology (n = 33), and patients with CGP and bronchiectatic disease (n = 37). The control group consisted of somatically healthy individuals with intact periodontium (n = 40). Dental indices (PMA, PI, Muhlemann, OHI-s), infl ammatory markers (transforming growth factor beta 1 (TGFβ-1), lactoferrin (LF), interleukin-8 (IL-8), C — reactive protein (CRP)), and oxidative stress markers (malondialdehyde (MDA), as well as advanced oxidation protein products (AOPPs), and total superoxide dismutase (SOD)) were analysed in all patients included in the study. The method of binary logical regression was used to create a mathematical model for assessing the risk of CGP progression in patients with bronchiectatic disease.Results. Dental indices and the level of markers of infl ammation and oxidative stress were statistically signifi cantly higher in all patients with CGP as compared to somatically healthy individuals, as well as in patients with CGP and bronchiectatic disease as compared to patients with CGP without general somatic pathology. Positive correlations of different strength between the studied markers of infl ammation and oxidative stress and dental indices were revealed. Based on the results of the correlation matrix data and using the binary logistic regression method, a mathematical model was developed that can be applied for assessing the risk of CGP progression in patients with bronchiectatic disease. The predictors of progression included in the mathematical model were: PI, TGFβ-1 and AOPPs. Conclusion. The data obtained indicate a greater severity of infl ammation and oxidative stress in CGP patients with comorbid pathology in the form of bronchiectatic disease and the infl uence of these processes on the periodontal condition. The proposed mathematical model for assessing the risk of CGP progression in patients with bronchiectatic disease is characterized by a high level of sensitivity and prognostic signifi cance, thus being applicable for use in clinical practice
