Abstract
Statement of problem: Limited research on flowable resin has been undertaken on its application directly on dentin associated with the adhesive systems.
Purpose: This study was to evaluate the shear bond strength and fracture aspect of flowable resin on human dentin with various types of dentin bonding adhesives with thermocycling effect.
Materials and methods: Filtek-Flow(3M ESPE, USA) was used as flowable resin and Eighty human molars were randomly divided into 4 groups : three dentin bonding adhesives (Scotchbond-Multipurpose: 3-step conventional system, One-Step: One-bottle system, Prompt L-Pop: All-in-one, self-etching primer) and 32% etching treatment without bonding adhesive as a control group. For evaluating their durability of bonding, each group was subdivided : storaging in the water at 37℃(24 hours) and thermocycling (0℃-55℃, 30 seconds intervals, 1000 cycle). Shear bond strength tests were performed and resin-dentin interface and fracture mode were observed. Results were analysed by one-way ANOVA and Scheffe’s multiple range test.
Results and Conclusion: 1. At 0 cycle, the mean shear bond strength of One-Step exhibited the highest value of all groups(p<0.05), and there were no significant differences between Prompt L-Pop and Scotchbond-Multipurpose, Scotchbond-Multipurpose and control(p>0.05). After 1000 thermocycling, One-Step exhibited higher value than other groups(p<0.05), and there were no significant differences among other groups(p>0.05).
2. The shear bond strength of each group was significantly decreased after thermocycling except Scotchbond-Multipurpose(p>0.05). 3. The most common failure mode was adhesive type and mixed type, next in order.
