Profundidad de polimerización de las resinas Bulk Fill. Una revisión sistemática

Abstract

OBJETIVE: Determine the depth of polymerization of Bulk Fill resins. MATERIAL AND METHODS: This review was performed according to the prism statement, PubMed databases (Medline), consulted from January 2015 to December 31, 2019. It was included research published in English-Spanish language, the evaluation of the depth of polymerization of bulk fill resins through the microhardness test and / or ISO 4049, were included. Bibliographic reviews, clinical cases were excluded. RESULTS: A total of 76 articles were found, subsequently 6 potentially eligible studies that, added 4 from the manual search, were used for the evaluation of quality and risk of bias. The most important data from included studies were used. Most of the articles included were classified as having a high level of evidence. The ISO 4049 scraping method was the most performed by the included studies. Regardless of the "in vitro" method performed, the Bulk Fill resins would partially meet the 4mm depth of cure requirements. CONCLUSIONS: The fluid Bulk Fill resins have better values of polymerization depth and these are conditioned by factors such as irradiance and exposure time.
