Retratamento endodôntico manual e mecanizado: uma revisão de literatura

Abstract

The purpose of non-surgical retreatment is the complete removal of gutta-percha, obturation material and decontamination of the root canal system, allowing adequate modeling of the root canals for a new obturation. This endodontic intervention can be done manually and mechanized, with the reciprocating system being much discussed. This literature review aims to describe non-surgical endodontic retreatment, highlighting manual and mechanized removal of filling material. For this, searches were carried out for studies published on the same theme indexed in the following databases: Virtual Health Library (BVS), Scientific Electronic Library Online (Scielo), National Library of Medicine National Institutes of Health (Pubmed), Medline and Lilacs, the following keywords were used: “Filling”, “Endodontic failures” and “Endodontic retreatment”. When indicating retreatment, it is always important to make a correct diagnosis, observing the clinical signs and symptoms associated with imaging tests. Manual retreatment brings good clinical results and uses Kerr and Hedstroem manual files associated or not with chemical solvents. Currently, new systems have been created with the same purpose, such as mechanized systems that offer several benefits in retreatment such as agility during the procedure, causing less stress to the operator and greater comfort to the patient.
