Internal resorption was associated with long-term chronic inflammation of the pulp (chronic granulomatous pulpitis). When internal resorption is radiographically confirmed, endodontic treatment becomes a necessity. Vital teeth internal resorption appears radiographically as an oval enlargement of the pulp chamber and root canal with smooth, symmetrical outline. Internal granuloma is assumed to be an effect of the trauma, or pulp inflammation, the ailment is rare, asymptomatic and might progress rapidly, causing perforation.
It is difficult to remove the pulp tissue from the resorptive defect, since this area is not easily accessible for instrumentation. The delay of the endodontic treatment may lead the internal resorption to perforation, thus decreasing the chances of treatment success.
In the following paper, we present a total of two clinical cases with internal granuloma with perforation that have benefited of specific endodontic treatment.
