The Effect of Desensitizing-Toothpastes on the Bond Strength of Different Restoratives on Coronal/Root Dentin
Journal Title: Cumhuriyet Dental Journal - Year 2018, Vol 21, Issue 2
Abstract
Aim: The aim of the study was to evaluate the effects of two desensitizing tooth-pastes on the shear bond strength of resin composite and glass ionomer restorative materials to coronal and root dentin. Materials and Methods: 108 human third molars’ distal or mesial sides were ground flat with a silicon-carbide paper. The samples were randomly divided into 3-major groups (N=36) to be brushed with: Group A: Sensodyne Rapid Relief; Group B: Colgate Sensitive Pro-Relief; Group C: Colgate Total 12 toothpastes. Brushing was performed with tooth brushing simulator 2 times/day for 10 days with 10 strokes/brushing. They were further divided into three sub-groups (n=12) to receive the following adhesion protocols to coronal/root dentin. Group 1: Clearfil SE Bond + Filtek Z250 Composite; Group 2: Adper Single Bond2 + Filtek Z250Composite; Group 3: Riva Glass Ionomer Cement. Samples were kept in distilled water for 24 hours. Shear bond strength test was performed with Universal Test Machine (cross head speed: 0.5 mm/sec). The data were evaluated statistically. Results: For all restorative techniques evaluated, the least shear bond strength values were obtained after Sensodyne Rapid Relief usage. Riva Glass Ionomer Cement demonstrated statistically significant inferior shear bond strength values than resin composite. Conclusion: Self-etch systems may be the choice for adhesion after desensitizing toothpaste usage.
