Appl. No.:

8/549254

Inventors:

Edward S. Roth - Kew Garden Hills NY

International Classification:

A61C 1500

US Classification:

132329

Abstract:

An interproximal toothbrush and method for cleaning, irrigating and medicating a sub-gingival region with the same are disclosed. The interproximal toothbrush has outer and inner V-shaped portions having outer and inner working surfaces which form intersections at the distal ends from the spines, and bristles extending from the intersections which clean the deeper portions of the sub-gingival region between the teeth and gum. At least one aperture may be provided in at least one of the working surfaces such that irrigation fluid or a medicating, antibacterial or other cleaning agent may be dispensed from the aperture and be guided by the bristles to the sub-gingival region.

Abstract:

A method of irrigating and cleaning a sub-gingival region is provided by guiding a sub-gingival periodontal irrigator of a flexible material into an interproximal region. The sub-gingival periodontal irrigator has outer and inner V-shaped portions having outer working surfaces and inner working surfaces which intersect at their distal ends from the spines, such that a hollow space is present therebetween. Irrigation fluid, medication or antibacterial agents may be dispensed through at least one aperture in at least one working surface to the sub-gingival region.

Abstract:

A surface marking system, kit, and method enables a user to mark a pattern upon a surface. The components may include a rectangular marking material transfer body, a particularly marked alignment tape, and a series of spacer elements. The marking material transfer body includes a fixed dimension and at least one marking material transfer portion. The outer perimeter includes opposed mark-alignment edges. The alignment tape has a fixed width, a select length, and a marked anterior surface. The marked anterior surface includes a series of width-wise marks and a length-wise mark. The length-wise mark is centered relative to the fixed tape width. A select body dimension is firstly and successively positioned at a select number of sequentially spaced width-wise marks and mark-alignment edges are firstly and successively alignable with parallel length-wise marks. The spacer elements ensure parallel arrangement of the length-wise marks and provide overlap sections adjacent the mark-alignment edges.
