DENTAL FLOSS

摘要

A dental floss is produced from expanded polytetrafluoroethylene that has been coated with a friction enhancing coating such as a microcrystalline wax to increase the friction coefficient of the floss. The polytetrafluoroethylene is preferably expanded to form a structure having a plurality of nodes interconnected by fibrils. The floss has a tensile strength of at least about 10,000 psi and a weight of about 500 denier to about 1500 denier. The coefficient of friction of the wax coated floss ranges from about 0.08 to 0.25. The floss may be comprised of a single strand or multiple strands. The floss may contain an optional dentifrice or pharmaceutically active material for delivery to the tooth and gum surfaces during use.
