Objetivo: El objetivo de este proyecto de investigación fue evaluar el ángulo de contacto del adhesivo Monobond Etch & Prime en la cerámica disilicato de litio tratado con dos concentraciones de ácido fluorhídrico y dos tipos de limpieza. Materiales y métodos: Estudio experimental in vitro. Se realizó una cantidad de muestras de discos de cerámica obteniendo 4 grupos (n = 6 discos por grupo de trabajo) (9). Cada uno de estos discos fue colocado en el interior de un tubo de policloruro de vinilo (PVC) y fijadas con resina acrílica con la superficie fresada expuesta para los tratamientos de superficie, dividiéndose en grupos: ácido fluorhídrico al 5% y 10%. Luego se sometieron bajo dos tipos de limpieza (ultrasonido y ácido fosfórico) y se colocó una gota de Monobond Etch & Prime. Después del tratamiento de superficie los grupos de trabajo fueron evaluados mediante la metodología de ángulo de contacto en el software ImageJ usando los complementos LB-ADSA (lb), contac angle (ca), angle tool (at). Resultados: El menor ángulo de contacto se obtuvo con la concentración de ácido fluorhídrico al 5% y una limpieza de ácido fosfórico con la medición lb= 21.71±0.7A este fue significativamente menor (p0.05) Conclusión: El menor ángulo de contacto en cerámicas disilicato de litio se obtuvo con la concentración de ácido Fluorhídrico al 5% y la limpieza de ácido fosfórico.
Objective: The objective of this research project was to evaluate the contact angle of the Monobond Etch & Prime adhesive in lithium disilicate ceramic treated with two concentrations of hydrofluoric acid and two types of cleaning. Materials and methods: Study experimental in vitro. A number of IPS Emax2 ceramic disc samples were made, obtaining 4 groups (n = 6 per working group) (9). Each of these discs was placed inside a polyvinyl chloride (PVC) tube and fixed with acrylic resin with the exposed milled surfce for surface treatments, divided in groups: 5% hydrofluoric acid and 10%. Then they underwent two types of cleaning (ultrasound and phosphoric acid) and a drop of Monobond Etch & Prime was placed. After the surface treatment the working groups were evaluated using the contact angle methodology in the ImageJ software using the LB-ADSA (lb), contac angle (ca), angle tool (at) complements. Results: The lowest contact angle was obtained with the concentration of hydrofluoric acid at 5% and a cleaning of phosphoric acid with the measurement lb=21.71 ± 0.7A, this was significantly lower (p 0.05). Conclusions: The lowest contact angle in lithium disilicate ceramics was obtained with the concentration of hydrofluoric acid at 5% and the cleaning of phosphoric acid.
