Tratamiento de dentina intra-radicular y cementación de postes de fibra de vidrio usando cementos autocondicionantes. Revisión sistemática.

Abstract

Introduction: Endodontic teeth have lost tooth structure. Intra-radicular dentin needs to be pre-treated with 17% EDTA inside the canal, eliminating the dentin sweep and improving the adhesion of the post-dentin and cementum. The posts give retention and elasticity to the dentin. Self-conditioning cements simplify working time because hydrophilic acid monomers demineralize enamel or dentin and cause a strong bond. Objective: To determine the treatment of intra-root dentin and fiberglass post cementation using self-conditioning cements. Materials and method: The present analysis of this research is a retrospective, cross-sectional study. The search for articles was carried out in metasearch engines such as Pubmed and Medline, selecting 5-year-old articles referring to the topic. Result: Peritubular dentin is indicated to be more mineralized than intertubular dentin. Among the ideal methods for the preparation of intraradicular dentin, it is mentioned that EDTA at 17% is a better chelator due to the elimination of organic and inorganic tissue. It was obtained that the composition and characteristics of the fiberglass posts are constituted for the most part by epoxy resin. The protocol for fiberglass post cementation was evaluated where it indicates the one-step technique. Conclusion: Self-conditioning cements are ideal for the cementation of fiberglass posts, together with the treatment of intra-root dentin using EDTA.
