ABSTRACT A bristle shaft bundle for use in total disinfection of subgingival periodontal pockets, periodontal pocket edges and tooth surfaces has individual bristle shafts arranged coaxially in a ring. A rotationally symmetrical gingival edge cup is provided, in which the bristle shaft bundle is arranged so as to project outwardly in a cylindrical way, continuing in a shaped manner to a cross-section increasing in the shape of a circular cylinder. The two innermost, reinforced bristle layers exhibit in individual cases rotationally circular bristles and project above the multiply stepped, remaining layers, which drop away towards the outside. The inner layer projects further than the adjacent layer to form an exposed layer. A connection layer is provided with a pointed device and the inner layer is provided on the front face of the projecting section with a shaped cross-section which as chosen can be either corrugated, serrated, roof-shaped or pointed and forms an individual, coaxial bristle shaft ring.
