Abstract
Abstract The disclosure concerns an improved dental hygiene technique for removing plaque from human teeth wherein a loop of multifilament flossing thread is trained about fingers on opposite hands of the user and worked in the spaces between the teeth while maintained taut. The flossing loop may be joint-free and comprise many turns of a single, continuous filament, or it may be made from multifilament thread and have a joint formed by gluing, heat sealing, knotting or air splicing. The last mentioned type of loop may include at least one protruding tail which performs a mopping function during plaque removal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
77 words
A floss type plaque removal implement comprising a continuous loop of multifiliment thread having at least one joint region wherein overlapping portions of the thread are connected together securely, and at least one tail which is formed as an integral extension of said multifiliment thread from said joint region, the loop being so sized that it may be trained about fingers on opposite hands of the user and extend therebetween in a taut state through interdental spaces.
Claim 2
Dependent Claim
77 words
A floss type plaque removal implement comprising a continuous loop of multifiliment thread having at least one joint region wherein overlapping portions of the thread are connected together securely, and at least one tail which is formed as an integral extension of said multifiliment thread from said joint region, the loop being so sized that it may be trained about fingers on opposite hands of the user and extend therebetween in a taut state through interdental spaces.
Claim 3
Dependent Claim
38 words
