Immunocytochemical observations by light and electron microscopy of catechol-O-methyltransferase (COMT) were conducted in dental pulp by use of a specific antibody to soluble rat-liver COMT and the peroxidase-antiperoxidase technique. Immunoreactive deposits were found in macrophages. The pattern of localization suggests that COMT may function in extraneuronal inactivation of catecholamines in dental pulp.
