Gingival retraction cord with wet, drip-free astringent

摘要

An astringent retraction cord for use in dental therapeutics is provided by coating a gingival retraction cord with an astringent gel containing an astringent salt such as aluminum potassium sulfate and a bodying agent sufficient to stiffen the salt solution to stand on the cord. The gel coated retraction cord is adapted to be inserted into the gingival sulcus to effect retraction of gingival tissue.
