During the course of treatment of the root canal infection of left upper central and lateral incisors on which resin veneer gold crowns were set, we have observed that the resin was suffering expansion from some chemical change. The present report concerns with the clinical observation as well as the laboratory experiment on the solubility of resin material by various medical agents routinely used in the dental clinic. The summary is as follows. 1) A case of resin expansion was observed in which formalin-tricresol acted as the chief agent for the expansion. 2) Tricresol, formalin-tricresol, carbol, campho-phenique, modified phenol, thymol alcohol, creosote, eugenol, xylol and chloroform definitely dissolved the resin. 3) The patterns in which the resin was dissolved by the various agents could be classified into 3 types : in the first type the resin was dissolved following expansion, in the second type it was broken down into small pieces, and in the third type disintegration and expansion of the resin took place simultaneously.
