Abstract

One of the most critical steps of the resin restoration technique is adhesion. Mechanical stress during the restoration can displace or even causes fracture the restoration. Recently, new self-etch adhesive materials can reach optimal shear bond strengths although they aren’t as good as etch and rinse technique, which is gold standard. Their solvent type may classify adhesives into many groups.
Aim: This study evaluated the effect of solvents to shear bond strength (SBS) and how they have been effected by the aging procedure; immediate and after thermo-cycle.
Material and methods: Forty intact human molars were randomly divided in 4 groups. While 2 groups were restored by using ethanol/water containing adhesive (Tetric N-Bond Universal, Ivoclar, Liechtenstein) the others were restored by using 3 different solvent containing adhesive (Optibond All-in-one, Kerr, USA) which include; acetone, ethanol and water. And both of two groups were subdivided as immediate and after termocycled aging. Tetric N-Ceram (Ivoclar, Liechtenstein) was used as composite in all groups. The immediate groups were tested after 24 hour following the polymerization and the termocycled groups were tested after 10000-termocycled application. P <0.05 significance level was used all hypothesis tests.
Result: Immediate and termocycled groups showed statically similar (SBS). But all groups showed lower bond strength after thermo-cycle.
Conclusion: While the SBS values weren’t affected by solvent type, the thermo-cycle aging reduced the SBS values in all groups. The major factor for the decrease of the SBS values is the hydrolysis of resin-dentin interface components. (1)
