Xeno IV One Component Light-Cured, Self-Etching Dental Adhesive Intro Kit Xeno IV's chemistry is based on the proven PENTA resin technology from the Dentsply Caulk Prime & Bond® NT family of bonding agents. This technology offers high enamel and dentin bond strengths and superb sealing ability. Xeno IV brings this clinically proven success to the self etch category. By utilizing this technology, Xeno IV offers superior etching, priming, and bonding: all in a single bottle or unit dose delivery. Xeno IV is a single component bonding agent requiring no mixing; making it less technique sensitive. It has superb sealing ability including impregnating the smear layer and dentin tubules. Unlike other self etch bonding agents, Xeno IV is pH balanced reducing the risk of gingival irritation. Xeno IV offers high resin concentration, allowing for an increase in bonding performance while reducing the risk of post-operative sensitivity. Xeno IV is Fluoride releasing for added clinician security.
