METTL3 and pulpitis: To explore the role of m6A‐dependent RNA methylation in dental pulp inflammation, we used Pg LPS in the present study to establish a model of dental pulp inflammation, and we detected the m6A content and expression levels of m6A methyltransferase and demethylases, including METTL3, METTL14, FTO and ALKBH5.
