Solvent for endodontic cement composed of Ethyl Acetate, Amyl Acetate, and Thymol. This solvent, in the context of endodontic retreatment, achieves softening of conventional cement based on zinc oxide-eugenol and those based on phenolic resin. It reduces the risk associated with the use of motorized instruments during mechanical treatment. Substitute for Endosolv E and Endosolv R.
