title: Bond strengths of glass ionomers using a dentin adhesive.
abstract: OBJECTIVE
  To determine the effect of All-Bond 2 adhesive on the shear bond strengths to dentin of Fuji II LC, Photac-Fil, and Vitremer.
  
  
  METHODS
  The occlusal surfaces of 60 extracted human third molars were ground flat to expose dentin and were polished to 600 grit. The teeth were randomly assigned to six groups (n = 10). In three groups, dentin was treated using the conditioner or primer recommended by the manufacturer. In the remaining groups, dentin was treated with All-Bond 2 etchant, primer, and adhesive. Restorative materials were applied to the treated surfaces in gelatin capsule matrices and were light-cured. Specimens were thermocycled, and shear bond strengths were determined using a materials testing machine.
  
  
  RESULTS
  The use of All-Bond 2 improved the mean bond strength of Photac-Fil from 1.7 to 8.7 MPa, but decreased the bond strength of Vitremer from 7.3 to 5.5 MPa. The bond strengths of Fuji II LC were 7.5 and 7.9 MPa, with and without the use of All-Bond 2, respectively. ANOVA and Duncan's multiple range test showed that only the difference for Photac-Fil was statistically significant.
