The aim was to investigate the clinical performance of microRNA-199a-3p (miR-199a-3p) in patients with chronic periodontitis. 91 patients with chronic periodontitis and 78 healthy individuals were enrolled for the research subjects. MiR-199a-3p expression was detected using real-time quantitative PCR (RT-qPCR) assay. Pearson correlation analysis was used for the relevance of miR-199a-3p with inflammatory mediators. Receiver operating characteristic (ROC) and logistic regression were conducted for the evaluation of the diagnostic performance and risk factors of chronic periodontitis. Bioinformatics analysis was utilized for miR-199a-3p-related genes. MiR-199a-3p was distinctly decreased in gingival crevicular fluid from patients with chronic periodontitis. The area under the curve (AUC) was 0.978 to discriminate chronic periodontitis patients from healthy individuals. The negative correlation was observed between miR-199a-3p and inflammatory factors. Logistic regression showed that miR-199a-3p was an independently protective factor for the occurrence of chronic periodontitis. Bioinformatics analysis revealed that the predictive regulated genes of miR-199a-3p mainly concentrated in inflammatory-associated signaling pathways. MiR-199a-3p was attenuated in patients with chronic periodontitis and an underlying diagnostic biomarker for the disease. • MiR-199a-3p was distinctly decreased in chronic periodontitis. • The diagnostic capacity of miR-199a-3p was evaluated. • MiR-199a-3p ...
