TREATMENT OF INTERNAL ROOT RESORPTIONS
– Internal root resorptions are often detected coincidently on x-rays used for other reasons. Prior to treatment it is crucial to determine if there is a communication between the root canal system and the bone.
– 56 year old female was referred for endodontic treatment of 12. The CBCT confirmed an internal root resorption in the apical third of the root canal, without perforation to the root surface. The tooth was non-vital and diagnosed with apical periodontitis. Using a microscope the root canal treatment was completed and the resorption cavity was filled. The root canal was prepared with rotating, manual and reciprocating NiTi instruments. Active irrigation was performed with sodium hypochlorite. The obturation procedure was a combination of warm vertical technique with initial application of a master cone placed apically to the resorption. Seven months later, the control x-ray showed healing of the apical radiolucent zone.
– Treatment of internal root resorption should be initiated as soon as possible to stop the resorption process, which otherwise ultimately leads to pulp necrosis and bacterial infection.
