Galectin-3 as a biomarker for periodontal disease severity in postcoronavirus disease 2019 patients: A clinical and biochemical investigation

The current study's findings demonstrated that periodontitis patients and individuals with post-COVID-19 and periodontitis had increased Gal-3 levels in the serum compared to healthy participants. This study highlights the relevance of treating periodontitis during the post-COVID-19/long-COVID era and the need to maintain oral hygiene by identifying possible biomarkers and understanding specific underlying processes.
