Abstract
Periodontitis being an immuno-inflammatory disease can act as an aggravating factor for various systemic diseases. Therefore, it is of interest to document the prevalence of comorbidities among periodontitis and non-periodontitis Indian patients. 680 patients were enrolled, categorized into non-periodontitis group (Group A) and periodontitis group (Group B). Each group was again sub-grouped into comorbidities and non-co-morbidities. Periodontitis patients were found to have significantly more co-morbidities than non-periodontitis patients. Osteoporosis and obesity showed statistically higher levels in periodontitis patients. Hypertension, diabetes mellitus, cardiovascular diseases, and COVID-19 infection showed higher prevalence in periodontitis group, though the difference was statistically non-significant.
