Abstract
The process involves the application of heated water, above 40.degree. C., to the teeth with simultaneous rotary brushing to remove plaque. The apparatus is a turbine power unit adapted to be connected to the heated water faucet and adapted to sit in the sink. A heated water exhaust conduit from the unit and a flexible power shaft lead to a handpiece which has a rotary brush driven by the shaft and a nozzle connected to the conduit and directed at the brush.
Claims2
An apparatus for treating the teeth comprising a hollow cylindrical housing having a turbine journaled for rotation therein, the turbine having a central spindle, a water supply hose connected to an inlet tangential to the periphery of the housing and having a distal end with means to connect it to a sink water faucet, flexible drive means having one end connected to the spindle to rotate therewith, a handpiece including an elongated body receiving the distal end of the flexible drive and including rotary brush means and means connecting the distal end of the flexible drive means to the rotary brush to rotate it, exhaust passage means for the housing disposed on the periphery of the housing at a point spaced therearound from the inlet, rinse tap means in the housing disposed on the circumference thereof between the inlet and the outlet, nozzle means on the handpiece adjacent the brush and aimed at the brush and flexible conduit means connected between the tap and the nozzle, valve means in the handpiece adapted normally to close off the conduit means but openable to permit flow of water from the housing to the nozzle and a water-temperature-reading thermometer disposed in the exhaust passage means.
An apparatus for removing plaque from dental surfaces by simultaneous brushing and treating with hot water at least 40.degree. C. comprising:
- (a) means for supplying hot water,
- (b) toothbrush means having an elongate handle and a brush,
- (c) a flexible hose connecting the means for supplying hot water to the toothbrush means and extending along the handle to the brush to dispense hot water adjacent the brush, and
- (d) a hot-water-temperature-reading thermometer mounted on the apparatus and exposed to the hot water to measure the temperature of the water delivered to the brush.
