Investigations into the factors affecting the shear bond strength of multiple component and single bottle dentin bonding systems to dentin

grantor: University of Toronto'Part 1. Thermocycling and long-term shear bond strength study '. To compare the 'in vitro' shear bond strengths (SBS) of two fourth generation (Scotchbond Multi-Purpose [SBMP] and All-Bond 2 [AB2]), and three single-bottle (Single Bond [SB] One Step [OS], and Prime and Bond 2.1 [PB]) dentin adhesives after thermocycling and long term storage. 'Part 2. Dual cure bond strength study'. To evaluate the effect of two-step photopolymerization of Z100 composite resin and resin thickness on the shear bond strength (SBS) of Scotchbond Multi-Purpose and Single Bond to dentin. 'Part 3. Microhardness study'. To evaluate the effect on Knoop microhardness of dual-curing, material thickness, and storage in 37°C water for up to 7 days. (Abstract shortened by UMI.)M.Sc
