ABSTRACT:
An ansate oral prophylaxis device includes a hand engageable shaft having a bristle carrying head at one end. The head is configured for oral anti-carries and periodontal prophylaxis with simultaneous bristle contact against all accessible tooth and adjacent gingival surfaces on each reciprocal stroke. The head is configured with a spine and pair of generally planar side panels, each lying in a plane approximately 45.degree. from the plane of the spine. Bristles project perpendicularly from the spine for engagement against occlusal tooth surfaces, while bristles project perpendicularly from the side panels for engagement against buccal and lingual tooth side walls, gingival surfaces and tooth surfaces beneath the gum line. To assure softer bristle contact with gingival surfaces, the bristles of the side panels are progressively tapered in length with the longest bristles being furthest from the spine and the shortest bristles being adjacent the spine. The planes of the side panel bristle ends intersect at approximately 30.degree..
