non-surgical repair of internal resorption with mta: a case report

internal resorption is rare in permanent teeth. treatment is usually performed through warm gutta-percha technique. if the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. non-surgical repair of a perforating internal root resorption with mta was conducted in this case. before repairing the resorption, a master gutta-percha point was placed in the canal to maintain negotiability of the original canal path. then, mta was prepared and applied with a small carrier in the resorption area and compacted. thereafter gutta-percha was retrieved and the access cavity was closed with a temporary filling material. in the second visit, the root canal was obturated with gutta-percha and ah26 sealer using lateral compaction technique and subsequently, the crown was restored. the symptoms and signs ceased and the result was satisfactory at the 18 month follow-up visit.
