Zirconium oxynitrate etchant improves dentin bonding performance of single-component adhesives: 5-year in-vitro evaluation.
OBJECTIVE To evaluate, using microtensile bond strength (μTBS) testing and in situ zymography, the effects of an experimental zirconium oxynitrate-based etchant [ZrO(NO₃)₂; ZON] on dentin bonding performance and endogenous matrix metalloproteinases (MMPs) activity of two simplified adhesive systems after 5 years of art...
