GingiTrac is a medium-viscosity, vinyl polysiloxane (VPS) gingival retraction paste with 15% ammonium aluminum sulfate (alum) that gently displaces the gingiva from the tooth and stops bleeding. When used with GingiCap™ compression caps, the mechanical bite pressure of GingiCap combined with the astringent action of aluminum sulfate works to control bleeding and seepage in just minutes. GingiTrac cleans up easily and completely, without tissue trauma. GingiTrac MiniMix Starter Kit contains: 24 Cartridges, 24 Mixing Nozzles, 20 Regular-sized GingiCaps, 20 Large-sized GingiCaps, 1 Snub-Nose Snap-Fit Gun
