Recently, researchers have proved the potential value of lncRNAs and miRNAs in cancer screening, diagnosis, and treatment; for example, lncRNA PVT1 was found to regulate the progression of pulpitis by down‐regulating the expression of miR‐455‐5p 23, and lncRNA DCRF could regulate cardiomyocyte autophagy through targeting miR‐551b‐5p 24. This evidence concerns the gene PVT1 and pulpitis.
