USE OF IRRIGATING SOLUTIONS IN TOOTH PULPECTOMY DECIDUOUS: LITERATURE REVIEW
Main Article Content
Abstract
Cleaning the root canals is a crucial step for the success of endodontic treatment. For this reason, the search for effective irrigation solutions in endodontic therapy of primary teeth is frequent in research and demonstrates the need to find substances with less toxicity and greater efficiency. Therefore, the objective of the present study is to analyze the different irrigation solutions and protocols in the endodontic treatment of primary teeth, in order to build a clinical approach. For this, a literature search was carried out in the databases PubMed/MEDLINE, Cochrane Library, SCIELO, CAPES and VHL Regional Portal using the combination of the terms “deciduous tooth”, “root canal irrigants”, “pulpectomy” and its derivatives , associated with each other by the Boolean operator “AND” and adapted for each database. The searches were carried out from July to August 2020. A total of 192 results were found. After a critical reading, 8 studies were selected. The review included studies that addressed themost common irrigating solutions: sodium hypochlorite, chlorhexidine digluconate, citric acid and ethylenediaminetetraacetic acid (EDTA) in endodontic therapy of primary teeth. EDTA and chlorhexidine digluconate have low toxicity and sodium hypochlorite 1% combined with citric acid 6% has the most successful combination. The association of the two substances proved to be more efficient in cleaning the root canals and removing the smear layer. However, more studies are needed, mainly clinical, to confirm the best irrigation protocol for endodontic treatment of primary teeth.
