Purpose of this study was to evaluate the effect of sandblasting, monomer treatment and combined effect of sandblasting and monomer treatment of conventional denture base resin on tensile bond strength of heat and auto cure silicone soft liners. Two resilient liners Auto cure (Mollosil) and Heat cure (Molloplast- B) were selected. Fifty six samples with cross sectional area of 25 × 25 mm were prepared and divided into two groups (Group A heat cure and Group B auto cure). Each group was further divided into 4 subgroups (7 samples in each subgroup) dependent upon the surface pretreatment. Subgroup 1 was control group (no surface treatment), subgroup 2 samples were surface treated by sandblasting (250 μm alumina particles), subgroup 3 samples were treated with monomer (for 180seconds), subgroup 4 samples were given combined treatment with sandblasting and monomer. Resilient liners were processed between 2 poly methyl methacrylate surfaces, in the dimensions of 3 mm. Tensile bond strength was determined with Instron Universal testing machine, at a cross head speed of 5mm/min. The data were analyzed using one-way ANOVA, followed by Tukey HSD test (α = 0.05). Monomer and combined treatment significantly increased the tensile bond strength when compared with control. Sandblasting treatment significantly decreased the tensile bond strength when compared with control.
