The comorbid pathology in patients with chronic apical periodontitis

The purpose of this study was to study the relationship between teeth after endodontic treatment and/or with apical periodontitis, in patients with a number of systemic diseases and smokers among the adult population of Yaroslavl. Materials and methods of research. Medical history data were collected, including age, gender, presence of cardiovascular diseases, diabetes mellitus, allergies, smoking habits and data on endodontic dental treatment of 421 patients (10,540 teeth). The prevalence of depulpated teeth and the periodontal condition were assessed by orthopantomograms. The periapical status was classified according to the periapical Index PAI (PAI), chronic apical periodontitis was defined as PAI-score ≥3. The statistical analysis was carried out using the Stata/MP v. program.17.0 (StataCorp LLC, Texas 77845-4512, USA) using chi-square tests, odds ratio and confidence intervals (95%). The results and their discussion. The overall prevalence of chronic apical periodontitis and the prevalence of teeth after endodontic treatment was 2.2 and 4.2%, respectively. The high prevalence of depulpated teeth increased the likelihood of chronic apical periodontitis (p<0.0001). In the group of men, there was a higher percentage of teeth with chronic apical periodontitis (p<0.0001), a lower percentage of teeth after endodontic treatment (p=0.05) and a greater number of residual roots (with complete destruction of the crown of the tooth) (2.3%). Smokers were more likely to have teeth with chronic apical periodontitis (p=0.002) and the prevalence of teeth after endodontic treatment (p=0.045). A positive correlation was observed between the prevalence of teeth after endodontic treatment and diabetes mellitus (p=0.040). Conclusion. A higher prevalence of chronic apical periodontitis and/or teeth after endodontic treatment in smokers and patients with diabetes mellitus may indicate a relationship between the condition of the oral cavity and a number of systemic diseases.
