Device Description

Expa-syl is a paste containing aluminum chloride which is used for the temporary retraction and hemostasis of the gingival margin during dental procedures such as, but not limited to, dental impressions, seating of temporary and permanent restorations, restorations of cavities and placement of a rubber dam. The paste is extruded through the tip attached to the cartridge and applied into the sulcus through the use of the manual dispensing gun. The paste is left in place between 1 to 2 minutes, depending upon the tonicity of the marginal gingiva, and then removed by an air and water spray with simultaneous aspiration. A dry, retracted sulcus is obtained.
