Effect of silorane-based adhesive system on bond strength between composite and dentin substrate

Jefferson Ricardo Pereira et al. J Conserv Dent. 2015 Nov-Dec.

Abstract

Context: The complexities of the oral environment, the dentin substrate, and the different bond and composite resin systems represent a challenge to the maintenance of reasonable bond between the composite resin and the tooth structure.

Aims: To evaluate the effect of the adhesive system on bond strength between silorane-based composite resin and dentin.

Materials and methods: Fourteen human molars extracted were selected and vertically cut into 3 dentin fragments, randomly divided among the experimental groups and restored with Z250 and P90 composite resin using different adhesive protocols (Adper Single Bond 2, Silorano primer, Adper SE Plus, and Scotchbond Multiuse). Two composite resin cylinders were built up on each dentin surface (n = 10) and subjected to a micro-shear bond strength test.

Statistical analysis used: Kruskal-Wallis one-way analysis of variance and Tukey test (P = 0.05).

Results: According to the results, Kruskal-Wallis test evidenced at least one statistical significant difference (P = 0.001). The Tukey test showed statistically significant differences among the group (P < 0.05). Group PSM8 (P90 + SM) showed statically significant higher results when compared with groups PSP4 (P90 + SP), PSB2 (P90 + SB), and ZSE5 (Z250 + SE).

Conclusion: The results evidenced that the monomer of the adhesive system has an effect on bond strength between the composite resin and dentin.

Keywords: Adhesive; composite resin; dental materials.
