Autoradiographic studies of the intracanal diffusion of aqueous and camphorated parachlorophenol in endodontics

Abstract

Studies of the penetrability of radio-labeled aqueous parachlorophenol and camphorated parachlorophenol were conducted by means of microscopic and autoradiographic techniques. The results indicated that aqueous parachlorophenol penetrated into the dentin from the pulp chamber and root canal and traveled at least to the cementodentinal junction, whereas the camphorated parachlorophenol did not. © 1973.
