Abstract:Micro-ribonucleic acid(miRNA) is a kind of non-coding single-stranded RNA, which can regulate the expression of genetic information by inhibiting mRNA translation of the target gene and participate in the occurrence and development of a variety of biological processes in vivo. miRNAs also take part in inflammatory diseases and tissue remodeling induced by mechanical forces. Mechanosensitive cells in periodontal tissue can lead to pathological/physiological changes such as periodontal inflammatory response and periodontal remodeling. miRNAs might have played important roles in the occurrence and development of force-related periodontal inflammatory diseases and tissue remodeling, by inhibiting the translation of specific genes in these cells. This article reviews the roles of miRNAs in force-related inflammatory response and tissue remodeling, especially in periodontal inflammatory response and tissue remodeling.
