A systematic review and meta-analysis of bond strength studies associated with self-etching primer and HF acid etching of dental glass-ceramics

Effect of hydrofluoric acid and self-etch ceramic primers on the flexural strength and fatigue resistance of glass ceramics: A systematic review and meta-analysis of in vitro studies

“…Hydrofluoric acid (HF) etching has become the main method of increasing the surface energy of glass ceramics as it effectively enhances the bond strength of these restorations [1] , [2] , [3] . Hydrofluoric acid reacts with silicon dioxide, which after subsequent reactions, forms fluorosilicic acid, a product soluble in water [4] , [5] .…”
