Uso de posicionadores radiográficos especiais em procedimentos endod nticos: relato de caso

The aim was to review the literature about the use of radiographic positioners in endodontic procedures and to report a clinic case in what this equipment was used. Getting images of quality and without distortions is important, because is necessary knowing the dental anatomy and the adjacent structures. For precise x-rays, it is necessary to correctly locate the X-ray film, angulations and distance of the cylinder with aid of radiographic positioners, which stabilizes the angulations, simplifying the technique. The option for RH positioner for radiographies under total isolation (Indusbello ) during endodontic procedures facilitates de exam and keeps the absolute isolation, giving space for de endodontic file in the radicular canal. The use of this positioner minimizes the errors and facilitates the taking of standardized images and bring more safety to endodontic treatment.
