Complexity of root canal treatment is well recognized, however some specific situations are still more difficult, such as treatment of apical third with accentuated curvature. Nevertheless, recent techniques of instrumentation and obturation brought new persperctives and became a determinant factor for successful treatment. Through the treatment of a maxillary left lateral incisor, with accentuated apical curvature, pulpal necrosis and periapical lesion through manual instrumentation and lateral condensation technique of root canal filling, this article is aimed to discuss whether these recent techniques of instrumentation and obturation of root canal are actually determinant factors for the success in endodontic treatment.
É reconhecida a complexidade do tratamento endodôntico. Algumas situações em particular apresentam características que podem representar dificuldades ainda maiores, entre as quais os canais que apresentam curvatura apical acentuada, necrose pulpar e lesão periapical. Nesse sentido, as novas técnicas de instrumentação e obturação trouxeram novas perspectivas e graças a isso assumiram a condição de fatores determinantes do sucesso. Através do tratamento de um incisivo lateral superior esquerdo com curvatura apical acentuada, necrose pulpar e lesão periapical, utilizando instrumentação manual e técnica da condensação lateral para a obturação, esse artigo pretende discutir se de fato as técnicas mais recentes de instrumentação e obturação do canal são fatores determinantes para o sucesso do tratamento endodôntico.
