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 provides high enamel and dentin bond strengths and excellent sealing ability. Xeno IV brings this clinically proven performance to the self-etch category. Utilizing this technology, Xeno IV offers superior etching, priming, and bonding in a single bottle or unit-dose delivery. It is a single-component bonding agent requiring no mixing, making it less technique sensitive. Xeno IV has superb sealing ability, including penetration of the smear layer and dentinal tubules. Unlike other self-etch bonding agents, it is pH balanced, reducing the risk of gingival irritation. With a high resin concentration, Xeno IV enhances bonding performance while minimizing post-operative sensitivity. Additionally, Xeno IV releases fluoride for added clinician security.
