Influence of acid-etching or double-curing time on dentin bond strength of one-step self-etch adhesives

Publication date: Available online 24 December 2014 Source:The Saudi Journal for Dental Research Author(s): Mohammed Q. Alqahtani This in-vitro study was undertaken to investigate the effects of an optional etching step with 35% phosphoric acid or double curing time on the shear bond strength (SBS) of one-step self-etch adhesives to dentin. A significant improvement in shear bond strengths was demonstrated when dentin was acid-etched with 35% phosphoric acid prior to the application of one-step self-etch adhesives. The use of curing time double that recommended by the manufacturers of the respective adhesives was capable of increasing the bond strength of Single Bond Universal Adhesive but not that of the other two adhesives (Xeno® V+ and AdheSE®One F VivaPen), indicating that the bond strength is adhesive-dependent. Therefore, the use of phosphoric acid-etching on dentin is highly recommended, followed by one-step self-etch adhesives.
