FIELD: medicine; stomatology . SUBSTANCE: toothpick designed for massage of the gums has rod base 1, massage-performing members 2 oppositely located on the ends of base 1, and cleaning members 3. Members 3 are trapezium-shaped in section, and they are located on the ends of the massage-performing members so that their smaller bases are directed towards the rod base longitudinal axis. All the massage-performing and cleaning members smoothly become narrower from two opposite sides towards the end of the cleaning member so that each massage-performing member forms a trapezium-shaped cross-section whose greater and smaller bases are directed oppositely across the rod base axis and are conjugate with bases of the cleaning members. There is a knurled surface on the side of each massage-performing member formed by the greater base of the trapezium. EFFECT: convenience in use.
