Influência do número de sessões do tratamento endodôntico na ocorrência de dor pós-operatória

Abstract

Endodontic treatment aims to reduce microorganisms inside the root canals, as well as prevent and treat apical periodontitis. Therapy can be conducted in a single or multiple consultations, and the occurrence of postoperative pain, resulting from inflammation of the perirradicular tissues, may the number of sessions. The present study aimed to review the literature on the influence of endodontic therapies in single and multiple sessions on the incidence of postoperative pain. Bibliographic searches were carried out in PubMed, SciELO and Capes Periodicals databases using the search key (endodontic treatment) AND (single and multiple sessions) AND (post- operative pain) without applying the year of publication restriction. Thirty-two articles were selected for reading and of these, sixteen met the inclusion criteria and participated in this review. Evaluated at intervals 24, 48, 72 hours, 7 and 30 days, a lower occurrence of postoperative pain was observed in the single-session approach. When comparing the incidence of pain between therapies, previous studies have not found a significant difference. In multi-session treatment, intracanal medication is used, whichcan help reduce bacterial load, but the intrusion of contaminated tissue during instrumentation is a risk factor in causing painful symptoms during treatment. It was concluded that there is no consensus in the literature on which endodontic therapy is more efficient when compared to the occurrence of postoperative pain regardless of time interval and the use of intracanal medication.
