Comparación de la adhesión de la resina en cavidades clase I de Black conformadas con dos tipos de fresa
Journal Title: Revista Eugenio Espejo - Year 2017, Vol 11, Issue 1
Abstract
A comparative observational study was carried out including the entire study population of 38 healthy third molars collected after extraction for medically justified reasons and with the consent of the respective patients. The ages ranged were from 20 to 25 years. It was distributed in two strata: group A (19) and group B (19) in order to compare the adherence of resin 3MZ250 in class I GV Black cavities by using two types of cylindrical dental burs brand jota, the one of fine grained and the other thick, in third molars in vitro. The research was developed in four stages obtaining the following results: in group A, the adhesion of the resin to the dental structure required a higher tensile force averaging 215.49 N to detach and in group B was 167.7 N. Statistical analysis using the T test allowed establishing that the difference in the tensile strength of the resin between groups A and B was significant. The use of dental burs of fine grained in the formation of class I GV Black cavities creates smoother walls that allow a better adhesion of the resin to the dental structure; so they are more resistant to tensile forces.
