An improved ligature is provided for use on a mouthpiece of a woodwind-type musical instrument. The ligature comprises a flexible, trapezoidal body having two longitudinal slots, and a pair of ferrules terminating each end of the body. The body is a rubberized fabric with one side being smooth and the other defined by a textured pattern. A tightening mechanism draws the ferrules together and thereby tightens the flexible body about the mouthpiece of the instrument. Each of the ferrules is formed with a longitudinal notch, and the ends of the body terminate inside by crimping and/or gluing the body end inside. The operation of the tightening mechanism within the ferrules in combination with the flexible nature of the body serve to effectively isolate the instrument mouthpiece from direct contact with the ferrules, thereby improving tonal response. The instrument's tonality may be adjusted by placing the smooth or textured side of the body in direct contact with the instrument and varying the relative position of the body and ferrules with respect to the reed.

A portable dental prophylaxis and bleaching system is provided for simultaneous tooth polishing and bleaching. It includes an oscillatory driving handpiece, a dental angle with a disposable rubber cup assembly, a dual-component dispenser, and a disposable mouthpiece. The battery-powered handpiece transforms a continuous rotation through a driving cam into a rotary oscillation which is then transferred through the attached dental angle to the rubber cup with an obtuse angle at its distal output end. The dispenser is operated manually to correctly apportion and mix the dual treatment materials into the rubber cup. In order to provide longer shelf life and effective bleaching action, the treatment materials are maintained at optimal pH values in separate compartments within the dispenser before use. The disposable mouthpiece is shaped for easy access to the user's teeth while protecting the gum surfaces. The system can be used both in dental clinics and at home.
