In Vitro Evaluation of Bond Strength of Adhesive Systems to Dentin and Stability of the Hybrid Layer

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Contemporary dental adhesives demonstrate strong durable adhesion to enamel while long‐term bonding stability to dentin remains uncertain. This in vitro study aimed to compare conventional dentin conditioning protocols supplemented with protease inhibition and chelate‐based conditioning protocols. Materials and Methods Four groups of

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.
