Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Effect of Silane Incorporation on the Bonding Performance of Universal Adhesives to Dentin

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Purpose The effect of silane in universal adhesives (UAs) on dentin adhesion remains unclear. Therefore, this study evaluated the dentin bonding of UAs with and without silane immediately and after thermocycling. Materials and Methods Sixty‐four sound human molars were randomly assigned to eight groups according to silane incorporation (UAs ...
