Association between polymorphisms in catechol‐O‐methyl transferase, opioid receptor Mu 1 and serotonin receptor genes with postoperative pain following root canal treatment

Abstract

The findings indicate that none of the evaluated SNPs for COMT, OPRM1, 5HT1A, 5HT2A and 5HTR3B genes were associated with the intensity of postoperative pain.
