Abstract:

This study evaluated the effect of dentin surface treatment on shear bond strengths of two visible light activated glass ionomer restorative materials to dentin. Cylinders of Fuji II LC and VariGlass VLC were bonded to dentin surfaces that were untreated, treated with a 10 polyacrylic acid GC conditioner, or treated with a dentin bonding agent primer Prisma Universal Bond 3 Primer. Specimens were thermocycled and tested in shear at 7 days. Data for each restorative material were subjected to one-way ANOVA and Tukeys procedure at the 0.05 probability level. For Fuji II LC, mean bond strength to Conditioner-treated dentin was significantly higher than mean bond strength to Primer-treated dentin and to untreated dentin. For VariGlass VLC, mean bond strength to Primer-treated dentin was significantly higher than mean bond strength to untreated dentin. Bond strengths to Primer-treated dentin and Conditioner-treated dentin were not significantly different. Visible light activated glass ionomers, Bond strength, Dentin treatment.
