Sellado dentinario inmediato como alternativa para evitar la sensibilidad postoperatoria en preparaciones de coronas.

Abstract

The preparation of the tooth for the placement of crowns undergoes a series of changes that have resulted in the presence of postoperative sensitivity, so that the new restorative dentistry has focused on trying to avoid sensitivity that represents a main problem in vital teeth when crowns are placed. Objective: To analyze the effectiveness of immediate dentin sealing as an alternative to avoid postoperative sensitivity in crown preparations. Materials and methods: This literature review has a retrospective, cross-sectional, descriptive, observational, analytical, non-experimental qualitative approach. Bibliographic metasearch engines such as: Pubmed, Scielo, Google Scholar and Cochrane were used, where 95 articles were obtained, of which 45 were not selected by exclusion criteria, leaving a sample of 50 articles; 30 articles were used for the analysis of the study. Results: The analysis of the variables indicated that nanofilled adhesives such as Optibond FL help to control postoperative sensitivity, especially in the provisionalization phase and during the cementation of the definitive crown, it was also indicated that postoperative sensitivity has a prevalence 3% and 34% when preparing a tooth, because it is a very traumatic procedure, which facilitates the appearance of postoperative sensitivity. Conclusion: To avoid postoperative sensitivity, an immediate dentin seal should be performed with a nanofilled adhesive such as Optibond FL, since the different studies showed that it was the most efficient with a resistance of 49.42 MPa.
