Endodontic treatment in a single session: selection criteria regarding postoperative pain

Endodontics was modified due to technological advances, and the implementation of the technology allowed previous treatments in multiple sessions to be performed in a single clinical visit. But despite the possibility of shortening the time of dental intervention, many professionals are still reluctant about Endodontic therapy in a single visit, mainly due to the possible appearance of postoperative pain. Thus, this literature review has tried to elucidate the advantages of the therapy in a single session, as well as when the Endodontic intervention can be performed during a visit. For this, articles found in the databases through the following keywords: Endodontic or root canal obturation and Postoperative Pain; Phoenix Abscess and Endodontic; Post operatory pain and Endodontic or root canal obturation; Preoperative pain and Endodontic were selected, reviewed and most appropriate, included in this narrative literature review. The results demonstrated that among the main advantages in the single view is the rapid return of tooth functions, reduction in the administration of anesthesia and antibiotic therapy, as well as the reduction in the chances of possible root recontamination. However, when it comes to postoperative pain, patients with pre-treatment pain will generally manifest painful sensation regardless of the technique used but as a way to prevent pain, treatment of non-vital teeth, with purulent or hemorrhagic exudation, with anatomical abnormalities or calcifications, presence of alveolar abscess, patients with previous flare-up and patients with symptomatic apical periodontitis, the procedure in a single visit should be avoided. In this way it is concluded that teeth with pulp alive or pulped teeth with absence of exudation, where the treatment time does not exceed 90 minutes, could be Endodontically treated in a single session.
