Description
Xeno IV is a 7th-generation dental adhesive containing fluoride. It incorporates a self-etching, light-cured adhesive in a single component with no mixing required and is indicated for use with direct light-cured composite and compomer restorations. Xeno IV adhesive is based on a water/acetone formula with a new cross-linking agent, AHPMA, incorporated to enhance the adhesion between the adhesive layer and the uncured restorative material. Due to a special combination of monomers, no separate phosphoric acid etching of dentin or enamel is necessary and is, in fact, contraindicated. Two coats of Xeno IV are scrubbed for 15 seconds each into the prepared tooth, followed by five seconds of gentle air to evaporated the solvent, and then light-cured for 10 seconds. The self-etching formula creates a homogeneous bond layer to cover the dentin and enamel to help reduce postoperative sensitivity. This product is available in an introductory kit comprised of a 4.5-ml bottle of adhesive plus accessories or a unit-dose package with 100 unit-doses plus accessories. Twenty-six consultants evaluated the unit-dose package of Xeno IV in over 700 clinical applications. This product received a 93% clinical rating.
