Cavitec is a eugenol and zinc oxide liner. It can be used as a base under composite or amalgam fillings that can be completed immediately. Cavitec will not discolor composite fillings. DO NOT use Cavitec under self curing resin restorations. Cavitec is also useful as a temporary stopping or filling agent and can be used for the temporary cementation of jacket crowns. When used as a temporary stopping, it breaks away cleanly when you are ready to insert the filling or crown.
