Abstract : There are different classifications of external root resorption. As Heithersay GS reported, treatment for invasive cervical resorption becomes difficult once the resorption reaches the apical portion. In the present case report, root resorption that continued from the root area of the lower right canine into the root canal was observed by CBCT. It was diagnosed as invasive resorption accompanying periodontitis. Regular root canal treatment, with rubber-dam and sufficient irrigation followed by obturation, was performed. After root canal obturation, a flap was opened under a microscope, followed by curettage of the granulation tissue of the resorption area from the periodontal ligament side. Then, MTA was used to seal the resorption area. At one-year follow-up, there was no tenderness, pus from periodontal pockets or any other symptoms. It is considered that the removal of granulation tissue and separation of the root canal from the periodontal pocket with MTA filling is effective for the treatment of invasive resorption.

Abstract : The implant periapical lesion (IPL), which is a possible cause of implant failure, may occur due to the presence of a pre-existing microbial pathology such as endodontic/periodontal lesions. A 27-year-old female patient underwent the placement of a screw-shaped submergible titanium dental implant in the maxillary anterior region. Six months after implant insertion, the patient visited our hospital and presented with a persistent pain resistant to analgesics. A periapical x-ray showed the presence of a radiolucency at the apical portion of the implant ; this image was confirmed by cone beam CT. Root canal treatment was performed to restore the bone defect in the neighborhood of the fixture. This paper presents a case history related to IPL, which was caused by a pre-existing endodontic lesion.
