Resumen

Clinical trials of porcelain veneers for chairside colour modifications may require the use of a trial resin with various colours of tints. The bond strength effects of four different solvents used for removal of trial resin from etched porcelain specimens were investigated. Fifty-six porcelain specimens were fabricated, flattened by a metallurgically standard method, etched with hydrofluoric acid and silane treated. The specimens were divided into four groups at random. The trial resin material was cleaned with different solvents prior to bonding of a dual cure resin composite button. After bonding the specimens were stored in water at 37°C for 7 days. Shear bond strength results were as follows: acetone (control) group, 12.9 ± 2.9 MPa; ethanol group, 15.1 ± 4.6 MPa; methanol group, 11.5 ± 2.9 MPa; methylene chloride group, 11.3 ± 2.4 MPa. No significant differences were measured (ANOVA, P > 0.05). The results indicated that the resin-porcelain bond strengths were not affected by the type of solvent used to remove trial resin. This procedure is recommended for clinical cases when resin composite is used for the try-in of etched porcelain bonded restorations.
