A non-lacerational technique to collect cells in an oral cavity utilizes a brush with bristles (40) which have an abrading surface that collect cells from the superficial, intermediate, and basal layers of the oral tissue. The brush includes a handle (20), and a brush head (26) extending from the distal end (24) of the handle (20). The brush head (26) includes at least one braided wire or cable (30) which forms a toroid (34) perpendicular to the longitudinal axis of the handle (20). Arrays (42) of bristles (40) are secured to the brush within the twisted wires or cable (30).

Il est utilisé, dans le cadre de cette technique évitant de lacérer des tissus et permettant de recueillir des cellules de la cavité buccale, une brosse dont les soies ont une surface abrasive propre à prélever lesdites cellules dans les couches, superficielle, intermédiaire et basale, du tissu buccal. La brosse est constituée d'un manche (20) et d'une tête (26) partant de l'extrémité distale (24) du manche (20). La tête (26) comporte au moins un fil ou un câble tressé (30) formant un élément toroïdal (34) perpendiculaire à l'axe longitudinal du manche (20) Des rangées (42) de soies (40) sont fixées à la brosse, à l'intérieur des fils ou câbles torsadés (30).
