Abstract
The purpose of this study was to evaluate the effects of 3 different enamel conditioners (10% polyacrylic acid, 37% phosphoric acid, and self-etching primer) on the shear bond strength and site of bond failure of a resin-modified glass ionomer (Fuji Ortho LC, GC Europe, Leuven, Belgium) bonded onto dry, water-moistened, and saliva-moistened enamel. One hundred eighty bovine permanent mandibular incisors were randomly divided into 12 groups; each group consisted of 15 specimens. Three different enamel surface conditions were studied: dry, soaked with water, soaked with saliva. One hundred eighty stainless steel brackets were bonded with the resin-modified glass ionomer. After bonding, all samples were stored in distilled water for 24 hours and then tested in a shear mode on a testing machine. After self-etching primer application, Fuji Ortho LC produced the highest shear bond strengths under all the different enamel surface conditions; these values were significantly higher than those achieved in the remaining groups, except when Fuji Ortho LC was used in combination with 37% phosphoric acid on dry enamel. Fuji Ortho LC bonded without enamel conditioning produced the lowest shear bond strengths. The bond strength of the groups conditioned with 10% polyacrylic acid was significantly lower than that of the groups etched with 37% phosphoric acid, except when both conditioners were used on enamel soaked with water.
