The EpiScreen device consists of a treated absorbent cotton fiber pad affixed to a nylon stick (Collection Pad) and a preservative solution in a plastic container (Specimen Vial). The Collection Pad is impregnated with a mixture of common salts and gelatin, creating a hypertonic environment which produces an osmotic gradient across the buccal and gingival mucosa. The pad is placed in contact with the gingival mucosa (between the lower gum and cheek) which enhances the flow of mucosal transudate onto the absorptive cotton fibers of the pad. Following the collection period, the Collection Pad is removed from the mouth and placed into a Specimen Vial. The vial contains a preservative solution which serves to inhibit the growth of oral microorganisms recovered on the Collection Pad. The vial is sealed with a plastic cap and transported to a laboratory for processing and testing.
