The external apical resorption represents a problem during the endodóntic therapy, it can eliminate the natural apical constriction, which would serve as limit of the instrument when we makes the conducts measures, biomechanical preparation and the obturation. In this work the comparison of two different orthodontic techniques is made (The technique of continuous arch slot 0,022" and the bioprogresive technique slot 0,018") with relationship to the external apical resorption, by means of an radiographic evaluation.
