Resumo(s)
Durante vários anos, a cirurgia apical era desconsiderada por diversos autores, pois a sua taxa
de sucesso era variável e imprevisível. Com a introdução de equipamentos mais avançados,
como o microscópio operatório, microinstrumentos, pontas ultrassónicas e novos materiais
retro-obturadores, surgiu a microcirurgia endodôntica.
Quando o tratamento endodôntico não cirúrgico e consequente retratamento endodôntico não
cirúrgico não são bem sucedidos, a microcirurgia endodôntica é, por norma, a opção
terapêutica delineada pelos Médicos Dentistas na tentativa de conservar o dente com
patologia periapical, evitando a sua extração.
Um protocolo meticuloso, envolvendo osteotomia, resseção apical radicular, análise do
fragmento apical radicular e retro-obturação do mesmo, deve sempre ser realizado sobre
magnificação através do microscópio operatório.
O estudo dos materiais retro-obturadores, nomeadamente o agregado trióxido mineral, e de
novas abordagens cirúrgicas, visam promover um avanço na técnica convencional
preconizada para a microcirurgia endodôntica.
For many years, Apical Surgery was disregarded by many authors, as its success rate was variable and unpredictable. With the introductions of state-of-the-art equipments, like the Operating Microscope, microinstruments, ultrasonic tips and new root-end filling materials, Endodontic Microsurgery emerged. When Non-Surgical Root Canal Treatment and consequent Non-Surgical Root Canal Retreatment are not successful, Endodontic Microsurgery is, as a rule, the therapeutic option outlined by Dentists, in the attempt to preserve the tooth with periapical lesion, avoiding its extraction. A meticulous protocol, involving osteotomy, root-end resection, root fragment analysis and retrofilling, should always be performed under the magnification of the Operating Microscope. The study of root-end filling materials, namely the mineral trioxide aggregate, and of new surgical approaches, aim to promote an advance in the conventional technique recommended for Endodontic Microsurgery.
