REPARO COMPLETO DA RADIOTRANSPARÊNCIA ÓSSEA PERIAPICAL EXTENSA DE PRÉ MOLAR INFERIOR COM DOIS CANAIS RADICULARES APÓS PREPARO COM SOLLA FILES COLLORS #35.04

The present study aims to report a clinical case of non-surgical endodontic treatment performed on a lower premolar with two root canals and an extensive periapical lesion. A 45-year-old female patient came to the private practice. After a complete clinical examination, endodontic treatment was initiated, with coronal opening, root canal exploration and root canal preparation using Solla Files Collors #35.04, associated with 2.5% sodium hypochlorite as an irrigating solution. The root canal system was obturated using the single cone technique associated with AH Plus endodontic cement. Clinical and radiographic follow-up was performed one year after the canal obturation. It is concluded that successful endodontic therapy is achieved when the diagnosis is correctly made, the canal system is sanitized, and the periapical bone radiolucency is repaired.
