RESUMEN
Adhesive dentistry is an essential component in the delivery of direct and indirect restorations. Ongoing discussions among scientists and clinicians have focused on whether or not current self-etch and universal adhesives adequately prepare enamel surfaces to achieve optimal bond strengths. To address these concerns, a selective enamel etch technique has been recommended. The definition of a selective enamel etch technique is as its name suggests. The clinician selectively etches the enamel of a cavity preparation by applying phosphoric acid etchant to the enamel surfaces of the preparation while refraining from applying the etchant to the dentin. This article explores the current research to help guide clinicians to achieve ideal outcomes when using dental adhesives. With few exceptions, the current scientific evidence recommends a selective enamel etch technique in conjunction with the clinician's adhesive system of choice.
