The purpose of this study was to determine whether presynaptic cholinergic receptors are present in sympathetic nerves in human dental pulp. Pulp was incubated with [3H]noradrenaline (0.6 mumol/l) for 30 min and then superfused with Krebs' solution at 1.0 ml/min. Electrical stimulation (100 sec, 5 Hz) increased the overflow of [3H]noradrenaline into the superfusate. Carbachol (10 and 100 mumol/l), an agonist of muscarinic receptors, decreased the stimulation-induced (SI) overflow of 3H, an… Expand
