Effectiveness of inmediate dentin sealing in indirect restorations

Abstract

Introduction: immediate dentin sealing consists of the application of an adhesive agent immediately after tooth preparation and before impression taking, providing a barrier for the dentin and pulp against microorganisms. Objective: to determine the effectiveness of immediate dentin sealing in indirect restorations. Method: a narrative review of the available bibliography was carried out using the analytical, synthetic and historical-logical methods through the articles retrieved from databases such as Pubmed, Scopus and Web of Science. A total of 39 references that addressed the main characteristics of the subject in question were selected. Results: the main objective is to protect the pulpal dentin complex immediately, playing an indispensable role in adhesive dentistry when performing indirect restorations, reduces dentin permeability in the short and long term, prevents the colonization of bacteria in the dentin, improves the marginal and internal adaptation and decreases previous sensitivity. Conclusions: immediate dentin sealing is of great importance in the clinical consultation, since great benefits can be obtained with this technique, such as better bonding strength, less space formation, protection of the dental pulp from bacteria, less bacterial microleakage, and low dentin sensitivity, however its effectiveness in marginal sealing is limited.
