Beneficios de la eliminación de la capa inhibida de oxígeno en restauraciones con resinas compuestas. Revisión bibliográfica.

Abstract

Composite resin is a versatile dental material that combines esthetic and restorative qualities, making it invaluable for dental restoration; it is used to enhance dental esthetics. Furthermore, it is crucial to address the oxygen-inhibited layer that forms during the curing process to ensure an effective and long-lasting bond. This layer, a byproduct of the reaction between oxygen and activating groups in the resin, serves to protect against oxidation and significantly improves the longevity of dental restorations. OBJECTIVE: To examine the scientific literature to describe the benefits of removing the oxygen-inhibited layer in composite resin restorations. MATERIALS AND METHODS: A bibliographic review of scientific articles was conducted by consulting databases, including Google Scholar, SciELO, Dialnet, ProQuest, and Scopus. Out of 123 articles, 41 were excluded based on title and abstract review. This left 82 articles for further analysis, of which 39 were subsequently excluded after a comprehensive content review. Ultimately, 43 articles were included in this review. A flowchart was implemented to streamline the validation and selection process. RESULTS: The review highlights two primary approaches for removing the oxygen- inhibited layer in composite resin restorations. First, the use of glycerin gel effectively dissolves unpolymerized monomers. Second, mechanical polishing with discs contributes to the long-term durability and overall quality of dental restorations. CONCLUSIONS: The removal of the oxygen-inhibited layer in composite resin restorations constitutes an indispensable procedure for enhancing the mechanical strength and longevity of dental restorations.
