Protocolo das possibilidades técnicas de aplicação dos sistemas adesivos universais: revisão de literatura com relato de caso

This case report describes the clinical application of a new universal adhesive system, Xeno Universal (Dentsply DeTrey, Germany) describing four application modes: self-etching, with or without selective enamel etching, or total etching followed by adhesive application on dry or moist dentin. Universal adhesive systems usually are versatile and easy to use, facilitating the operator, since the same product has several technical possibilities, thus reducing the operating time and the technique sensitivity. However, long-term laboratory studies and more clinical reports and/or clinical trials are needed to prove the quality of this new universal adhesive system, before dentists can start using them in their dental offices.
