Periodontitis is a polymicrobial, inflammatory condition affecting tooth-supporting tissues. It is characterized by a progressive loss of epithelial attachment and resorption of alveolar bone, which can lead to tooth loss. Epithelial-mesenchymal transition (EMT) has been proposed as a reversible process that shifts the cell phenotype from epithelial to mesenchymal-like and may be involved in the process of periodontal inflammation either completely or partially. Long non-coding RNAs (lncRNAs) are a large class of regulatory transcripts longer than 200 nucleotides lacking evident protein-coding potential. Studies have shown that lncRNA dysregulation plays key roles in human diseases, including cancer, by modulating the epithelial-mesenchymal transition (EMT). The involvement of lncRNAs markers in the pathogenesis of periodontal disease induced EMT has not been studied thoroughly and have created a gap in the knowledge.
