Evaluation of shear bond strength of silorane resin to conventional, resin-modified glass ionomers and nano-ionomer cements.
OBJECTIVE
To evaluate the shear bond strength of silorane composite resin to conventional and resin-modified glass ionomer cements.


METHODS
Shear bond strengths of Vitrebond (Group I), Ketac N100 (Group II) and Ketac Bond (Group III) glass ionomer cements to the composite Filtek P90 were evaluated. The bond strength was tested using a universal testing machine at a cross-head speed of 0.5 mm/min. Comparison between the groups was carried out using an analysis of variance test and pairwise comparison using Tukey's post-hoc test with a significance level of P ≤ 0.05.


RESULTS
The measured bond strengths were 17.14 ± 3.39 MPA for Group I (Vitrebond), 15.34 ± 3.39 MPa for Group II (Ketac N100) and 14.12 ± 2.79 MPa for Group III (Ketac Bond). Group I achieved higher bond strength than Groups II and III.


CONCLUSIONS
Resin-modified glass ionomer cement (i.e. Vitrebond) appears to be preferable to nano-ionomer glass ionomer cement (i.e. Ketac N100) and conventional glass ionomer cement (i.e. Ketac Bond) as a base under low-shrink posterior composite (i.e. Filtek P90).
