Periapical surgery with transsurgical filling of a tooth with extensive periapical lesion: case report

This paper aims to describe a case of endodontic treatment associated with surgical treatment with apical curettage, apicectomy and transsurgical filling of a right upper lateral incisor with extensive periapical lesion. The patient attended the dental office reporting pain, facial swelling and fever. On clinical examination, an increase in extra and intra-oral volume was observed, affecting the bottom of the right upper sulcus; there was a negative response to the sensitivity test on tooth 12. The periapical radiograph showed the presence of an extensive periapical lesion involving the apices of teeth 11 and 12. In light of these findings, conventional endodontic treatment was chosen. The chemical-mechanical preparation was performed with X1-Blue mechanized files associated with 2.5% sodium hypochlorite and, after three changes of intracanal medication with calcium hydroxide, exudation through the canal persisted. Therefore, a periapical surgery was performed with curettage of the lesion, apicectomy and transsurgical obturation associated with AH Plus sealer. After 7 months of follow-up, complete regression of the periapical lesion was observed. In view of the limitations, the success of this case can be attributed to the association of endodontic treatment with the chosen surgical technique, since a repair of the periapical bone radiolucency was observed.
