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) compared to the different measurements ca= 19.85 ± 4.7A, at= 21.09 ± 4.77A where no significant difference was obtained. (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.
