Agentes utilizados na desinfecção do alginato como material de moldagem: uma revisão integrativa

Abstract

A mold disinfect is indispensable for maintaining a labor flow at the risk of cross infection. However, alginate after disinfection may have dimensional changes and in the reproduced oral details. Thus, the objective of this study was to perform an integrative review about the materials used in alginate disinfection as a molding material, as well as understanding the properties, modes of use, formulations, impression effects and antimicrobial action. For this, a search in the PubMed and Scopus databases using the combined descriptors “Dental Impression Materials”, “Disinfection” and “Alginate”. Only original articles (in vitro, in vivo) published in the last 10 years have been included, a total of 45 studies have been selected, 10 after careful reading of the titles and summaries. The studies analyzed showed the use of 7 marketed disinfectant products, 3 proven action disinfection agents, a natural extract solution and an alginate with antimicrobial properties. Of the studies that proposed this assessment, only Minuten had no antimicrobial effect. Regarding spray disinfection, the application ranged from 10 seconds to 10 minutes. And by immersion in solutions, ranged from 15 seconds to 30 minutes. Regarding dimensional stability, 0.12% chlorhexidine incorporation into manipulation and the use of MD520® did not significantly interfere. An antimicrobial alginate marketed did not interfere with the properties of the plaster. And in the reproduction of NACLO 5.25%, Glutaraldehyde, Aseptoprint® Liquid and Zeta 7 Solution® agents, was considered adequate. NaClO is considered the reference chemical agent for disinfection. Most other tested products do not have a defined time and application mode. Therefore, more studies are needed to define the ways of use of these new agents. And the use of sodium hypochlorite, EPIMAX® and MD520®, are more effective in disinfection and safe in relation to models reproduction.
