Abstract:
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).
