Effects of local anesthetics on the respiratory activity in vitro of cells in the dental pulp.

ABSTRACT

The respiratory activity of isolated dental pulps from rat incisors was studied using a Gilson respirometer. The activity was compared with activities after administration of varying concentrations of commercial standard solutions of lidocaine with and without adrenaline and prilocaine with felypressin. Above a 2.5% concentration of the standard solution added to the respiratory medium a significant inhibition was registered.
