Influence of Photoinitiator and Light-Curing Source on Bond Strength of Experimental Resin Cements to Dentin.
This study evaluated the bond strength (BS) of experimental resin cements formulated with different photoinitiators when activated by two kinds of light-curing units (LCUs) through a ceramic material. Seven resin blends with different camphorquinone (CQ) and/or phenylpropanedione (PPD) concentrations (weight) were prepared: C5: 0.5% CQ; C8: 0.8% CQ; P5: 0.5% PPD; P8: 0.8% PPD; C1P4: 0.1% CQ and...
متن کاملEffects of different surface treatments and accelerated artificial aging on the bond strength of composite resin repairs.
The purpose of the present study was to assess the bond strength of composite resin repairs subjected to different surface treatments and accelerated artificial aging. 192 cylindrical samples (CSs) were prepared and divided into 24 groups (n = 8). Half of the CSs were stored in water for 24 h, and the other half were subjected to C-UV accelerated aging for non-metallic specimens. The treatments...
متن کاملEvaluation of Tensile Bond Strength between Dentin and Metallic Copings Using Different Resin Cements
Statement of the Problem: For a successful clinical outcome, luting agents should have a high bond strength. Bond failure is still one of the main reasons of restoration failures. Purpose: The present study was designed to comparatively evaluate the retention of metallic copings using different resin luting cements. Materials and Method: In the present experimental study, 40 intact premolar tee...
متن کاملShear bond strength of resin cements to human dentin.
OBJECTIVES The objectives of this in vitro study were (1) to assess the bond strength of the universal cement RelyX Unicem to dentin and to compare it with three conventional resin cements, (2) to test the influence of aging on their bonding capacity and (3) to test the influence of the operator on bonding quality by performing the same test in two different centers. METHODS 160 third molars,...
متن کاملShear Bond Strength of Dental Self – Adhesive Resin Cements
The continuous technological advance and increasing availability of new dental self adhesive resin cement in the market, coupled to the demands of daily clinical practice, have made the determine mechanical properties. This study evaluated the shear bond strength of ceramics cemented by three different dental self-adhesive resin cements. Shear bond strength was measured with an Instron servo hy...
