ABSTRACT:
Dental floss impregnated with a pressure sensitive dye for marking teeth. The pressure sensitive dye is released in response to the application of interproximal pressure when the dental floss is inserted between a tooth and an adjacent tooth having an interproximal spacing less than the diameter of the dental floss. The pressure sensitive dye produces a localized stained area at locations of interproximal tooth contact between the two teeth so that the dentist points of contact between crowns, bridges and natural teeth.
