Bond strength performance according to the adhesive technique used in universal adhesive systems, literature review

Introduction: Adhesive dentistry faces complex clinical situations, which require the dentist to be able choose best adhesive protocol offered by universal adhesives. Objective: To present current information about performance in bond strength according etching technique used adhesives, evaluating total technique, selective enamel etching, self-etch and bonding special situations. Methodology: A search was carried out PubMed electronic database using as keywords “universal adhesive”, “total etch technique”, “selective etching”, “self-etch”. Results: In acid gel must considered, well type of adhesive. Selective seeks obtain that strong anchorage can only obtained a phosphoric gel, allowing self-etching quality act on dentin. The use will simplify steps protocol, however adhesion may decrease consequently. If there is any alteration substrate adhered, resulting force could modified, regardless used. Conclusion: Universal adhesives allow clinician depending situation they are facing, long pays attention aspects such used, application time conditions adhere.
