Abstract

An ultrasonic dental tooth treatment system includ-ing an ultrasonic dental handpiece, a fluid reservoir hous-ing and a power control housing. The reservoir housing is supported by the control housing. The reservoir housing encloses two containers which are connected to the selec-tor valve. The selector valve is connected to a control housing conduit which is connected to the handpiece. The control housing encloses a power control circuit which is connected to the handpiece. In a preferred embodiment of the invention a fluid dispenser includes at least one read-ily removable reservoir container supported by a reservoir housing having a pivotable cover and a fluid control valve.
The cover is pivotable between an open position and a closed position. The valve is closed by the cover when the cover is in its open position.
