Statement of problem. There is little information regarding the mechanical and chemical retention of polymer-glass composite to cast titanium.Purpose. This study examined whether sandblasting in conjunction with silicoating improves the bond strength of the polymer-glass composite to cast titanium.Materials and methods. Disk patterns (10 mm in diameter, 2.5 mm thick) were cast with commercially pure titanium (CP Ti) and Type IV gold alloy. Three pretreatments were applied: 50 mu m Al2O3 sandblasting (50 SB), 250 mu m Al2O3 sandblasting (250 SE), and 600-grit SiC paper polishing (600 SiC). After surface preparation, the Siloc system tem (silicoating) was applied on the disks. The 50 SE specimens without Siloc system were also prepared as controls. Then sticky rapt: with a circular hole (4.76 mm diameter) was placed onto the disk to define the bonding area. Artglass (polymer-glass) opaque, dentin, and enamel composites were applied using Teflon matrices and then light-polymerized. Shear bond strength (n = 8) was determined at a crosshead speed of 5 mm/min. Results mere analyzed statistically with 2-way ANOVA and the Tukeg-Kramer test (alpha=.05).Results. The Siloc system significantly (P
