ABSTRACT

En endodoncia la tomografía cone-beam (CBCT) permite el diagnóstico y planifi cación de tratamientos. Se presenta un caso en que se detectó una desviación del conducto radicular y perforación al instalar un poste, las cuales no fueron identifi cadas en la radiografía convencional. La tomografía cone-beam facilitó el diagnóstico y la defi nición del plan de tratamiento, el cual se realizó bajo microscopio y con ultrasonido para remover los materiales de obturación previos (gutapercha y poste). Las perforaciones iatrogénicas son causa de mal pronóstico en los tratamientos endodóncicos. El cone-beam es una herramienta que permite observar tridimensionalmente los conductos radiculares, lo que facilita el diagnóstico y tratamiento a seguir (AU)


Cone-beam (CBCT) tomography is more often used in endodontics, to improve diagnosis and treatment planifi cation. In the present study we were able to detect a deviation of the root canal and perforation during the colocation of a poste, which wasn't possible with conventional radiograph. The endodontic treatment was guided with cone-beam and was executed under microscope; help out with ultrasonic tips to remove the previous obturation materials (gutta-percha and post) to also detect the original tract and to clean and desinfect the original root canal. Iatrogenic perforations cause poor prognosis of the endodontic treatments. CBCT is a tool that allows observing three-dimensional the root canals; which facilitates the diagnosis and treatment planning (AU)
