Abstract
MicroRNAs (miRNAs) have been found to participate in the pathogenesis of several
immune-related conditions through the modulation of the expression of cytokine coding genes and
other molecules that affect the activity of the immune system. Periodontitis is an example of these
conditions associated with the dysregulation of several miRNAs. Several miRNAs such as let-7
family, miR-125, miR-378, miR-543, miR-302, miR-214, miR-200, miR-146, miR-142, miR-30
and miR-21 have been shown to be dysregulated in patients with periodontitis. miR-146 is the most
assessed miRNA in these patients, which is up-regulated in most studies in patients with periodontitis.
In the present review, we describe the impact of miRNAs dysregulation on the pathoetiology of
periodontitis.
