Abstract: Due to contribution of the iodoform as intracanal medication to disinfecting the root canal system, the present study sought to investigate in vitro, the macroscopically perceptible extra-radicular changes of a root containing iodoform as the intracanal medication to determine if the iodoform can either transpose or generate products that can transpose the dentine and cementum barriers. To this proposal, the cervical third of a palatal root of a first maxillary molar was sealed with glass ionomer and cyanoacrylate and part of the apical third of the same root was sealed with a dentin and cyanoacrylate barrier. This root containing iodoform was immersed in carbon tetrachloride and the change in color of this product was observed. The carbon tetrachloride showed changing of color about 7 days in the samples containing iodoform that become more concentrate until period of 30 days, using or not apical sealing. It can conclude that iodoform transposes or has products that transpose the dentin and cementum barriers and reaches the extra-radicular environment.
