This study evaluated the expression of genes involved in chronic pain conditions in apical periodontitis (AP) tissues. MMP9, TIMP1, TNFA, CAMK4, and COMT mRNA expression levels significantly increased in AP tissue samples compared with controls. In addition, positive correlations were observed between the expression of TIMP1 with COMT and CAMK4, TNFA with TIMP1 and CAMK4, and COMT with CAMK4. This study confirms the upregulation of MMP9, TIMP1, and TNFA in AP tissues and reports, for the first time, the expression of CAMK4 and COMT as suggestive of their involvement in AP pathogenesis.
