Efecto de la concentración de ácido fluorhídrico sobre el ángulo de contacto de silanos de uno y dos pasos en cerámica de disilicato de litio

Abstract

Objetivo: Evaluar el ángulo de contacto del silano de uno y dos pasos en una cerámica de Disilicato con tres concentraciones de Ácido fluorhídrico. Materiales y métodos: Se utilizó 36 bloques de cerámica y se dividió en dos grupos: grupo con silano de uno y dos pasos, y con las concentraciones de ácido fluorhídrico al 5%, 9% y 10 % respectivamente. Para evaluar el ángulo de contacto se colocó una gota de silano en el centro de las cerámicas previamente grabadas y posteriormente mediante técnicas fotográficas se obtuvo imágenes de la gota para analizarlas en un software Image J Resultados: En un tratamiento de superficie con silano de un paso y ácido fluorhídrico al 5 %, 9% y 10% los ángulos de contacto obtuvieron diferencia significativa. Con silano de dos pasos, con el tratamiento de superficie con ácido fluorhídrico al 9 % se mostró diferencia significativa con respecto al ángulo de contacto entre las concentraciones de ácido fluorhídrico al 5% y al 10%. Conclusión: En el tratamiento de superficie con ácido fluorhídrico al 10% y silano de un paso, se mostró un menor ángulo de contacto y con silano de dos pasos, se mostró un menor ángulo de contacto con la concentración de ácido fluorhídrico al 5% y 10%.

Objetive: To evaluate the contact angle of the silane of one and two steps in a disilicate ceramic with three concentrations of hydrofluoric acid. Materials and methods: Were used 36 ceramic blocks and it was divided into two groups: group with one- and two-step silane, and with hydrofluoric acid concentrations at 5%, 9% and 10% respectively. To evaluate the contact angle, a silane drop was placed in the center of the previously etched ceramics and later using photographic techniques, images of the drop were obtained to analyze them in an Image J software. Results: In a surface treatment with one-step silane and hydrofluoric acid at 5%, 9% and 10%, the contact angles obtained significant difference. With two-step silane, the surface treatment with 9% hydrofluoric acid showed a significant difference with respect to the contact angle between the 5% and 10% hydrofluoric acid concentrations. Conclusion: In the surface treatment with 10% hydrofluoric acid and one-step silane, a smaller contact angle was shown and with two-step silane, a smaller contact angle was shown with the 5% and 10 % hydrofluoric acid concentration.
