Popis: | Objective: To compare four different surface treatment methods and determine which produces adequate bond strength between ceramic brackets and facets of porcelain (feldspathic), and evaluate the Adhesive Remnant Index (ARI) scores. Materials and Methods: Ten facets of porcelain specimens with glazed surfaces were used for each group. The specimens were randomly assigned to one of the following treatment conditions of the porcelain surface: (1) no surface treatment (control group), (2) fine diamond bur + orthophosphoric acid gel 37%, (3) hydrofluoric acid (HFL) 10%, and (4) HFL 10% + silane. Ceramic brackets were bonded with the adhesive cement Transbond XT. The shear bond strength values were measured on a universal testing machine at a crosshead speed of 0.5 mm/min. Results: There was a significant difference (P |
