Fallos de los diferentes sistemas adhesivos en las estructuras de esmalte y dentina. Revisión sistemática.

Abstract

Introduction: In dentistry, adhesion is understood as the union that exists between the restorative material and the dental structure. If there is no good adhesion protocol, to determine failures, generate leaks and possible restorative failure. Objective: Describe the failures of the different adhesive systems in enamel and dentin structures. Materials and Methods: The present study is a type of cross-sectional, bibliographic or documentary research, retrospective in the bibliographic search, with a qualitative methodological approach, with a descriptive and analytical design and a deductive method. Use of P.I.C.O. analysis to obtain keywords: adhesive failures, adhesion failures, adhesive systems, dentin, enamel, protocol; Using the search engines Pubmed, Medline, Elsevier, Journal, Cochrane, Dialnet Plus, Science Direct, 50 related articles were found, and 31 articles were studied based on inclusion and exclusion criteria. Results: The study determined that there is a better adhesion to enamel than to dentin due to the fact that the composition of the enamel is mostly inorganic, there is more adhesion failure due to the unstable formation of the hybrid layer, the inadequate acid etching technique, incorrect adhesive infiltration technique and subsequent polymerization, and the erroneous way in placing the insulation, for which it is determined that the adhesive systems with the most failures are the self-etching ones and their most common consequences are postoperative sensitivity and microleakage Conclusion: Failures in adhesion can be varied, therefore, a technique must be performed that meets the three objectives of dental adhesion: preserve more dental structure, achieve optimal and lasting retention, and prevent microleakage.
