Diagnosis was made by clinical manifestation, intraoral periapical radiograph and cone beam computed tomography (CBCT). CBCT has superior diagnostic accuracy that results in better management of complicated cases. Due to hemorrhage from the perforation site into the canal, and inability to dry the canal space surgical approach was employed to seal the resorptive defect. Clinical and radiographic examination revealed a successful outcome six months after treatment. Key words: Internal Resorption, cone beam computed tomography, surgical management. https://jcr.tums.ac.ir/index.php/jcr/article/view/111 https://jcr.tums.ac.ir/index.php/jcr/article/download/111/138
