Evolución y efectividad de los sistemas adhesivos de séptima y octava generación en restauraciones directas. Revisión bibliográfica.

Abstract

Introduction: Dental adhesion is responsible for the chemical processes of dentin-enamel union for a correct choice before its application in restorative treatments; it is important to know properly the generation to which it belongs, its properties, application techniques, etc. All this is to ensure success in the procedures to be performed. Currently, adhesive systems have evolved, and 8 generations are available in the market, each with a betterquality standard than the previous one. Objective: To identify which generation of the adhesive system is the most viable to be applied in direct dental restorative treatments. Materials and methods: A review and compilation of 56 articles published from 20 years ago to date was carried out. The articles selected focused on describing the generations of adhesive systems applied only with direct restorations, including clinical case reports. Google Scholar, SciELO, and databases of interest, such as PubMed, Scopus, and Medigraphic were used. Conclusion: The advancement of technology implies new knowledge; therefore, the effectiveness of adhesive systems has changed significantly. Scientific evidence has shown that seventh-generation adhesives are more effective in direct restorations.
