Gingival Retraction Paste Redefining Gingival Retraction!!! ATYANTA Gingival Retraction Paste is a high viscosity gingival retraction paste used for the temporary retraction of the gingival margin to provide a dry sulcus when creating direct or indirect restorations. The astringent action of aluminium chloride works to open the gingival sulcus and control gingival fluids when taking impressions or during placement of permanent restorations.
