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 andmethods:
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 degree C(24 hours) and thermocycling (0degree C-55degree C, 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 andConclusion:
1. At 0 cycle, the mean shear bond strength of One-Step exhibited the highest value of all groups(p0.05). After 1000 thermocycling, One-Step exhibited higher value than other groups(p0.05). 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.
