The endodontic surgery is indicated in cases of failure and/or impossibility of conventional endodontic treatment. Among the existent modalities in the endodontic surgery, the retrograde filling consists on preparation of apical cavity and filling with a retrofilling material. The technical-scientific progress in Endodontics become possible the use of retrotips activated with ultrasonic for retrocavities preparation with appropriate extension and following the long axis of the root. The aim of the study was to present the current resources in the preparation of the retrograde cavity in endodontic surgery, detaching their advantages in comparison with the use of conventional preparation with burns. A review of the literature will be presented, considering the use of ultrasound and laser for retrograde preparation, seeking the current resources that provide better apical preparation, resulting in better prognostic of the endodontic surgery (AU)

The apical surgery with simultaneous root filling consists in the elimination of the local etiologic factors concomitant with the shaping and obturation of the root canal system. This technique is indicated when there is no possibility of obturating the root canal by conventional methods. Some adverse factors may difficult the clinical procedures, such as the radiographic interpretation. Periapical radiographs must not be used as the main diagnostic resource due to their inherent disadvantages, such as distortion and superimposition with other anatomical structures. The aim of this clinical case report is to show the limitations of radiographic examination in an apical surgery in which a root perforation was not visible in the radiographic image, as well as the gutta-percha was not related to its real clinical location.
