310 having a transducer 320 located at or near one end of the wand the wand 310 is preferably made of a rigid or semi rigid biocompatible material such as for example plastic or thermoplastic the transducer 320 may be either mounted at the end of the wand 310 or within a cavity not shown in the wand 310 while a single transducer 320 is illustrated in fig5 it is understood that the transducer 320 may be comprised of multiple transducers that are stacked or otherwise incorporated on or within the wand 310 the transducer 320 may be any type of transducer suitable for converting electrical energy into vibrational and or acoustical energy such as a resonance type ultrasonic sonic or supersonic transducer these transducers produce high intensity waves or energy by for example applying the output of an electronic oscillator to a thin wafer of piezoelectric material e g lead zirconate titanate pdzrti or pzt or barium titanate batio 3 which acts as a vibration element if the transducer 320 is mounted at the end of the wand 310 it should be preferably coated with a protective biocompatible coating such as for example teflon that seals and electrically insulates the transducer and provides a smooth surface for applying the transducer to a patient 39 s teeth gums or other tissue alternatively if the transducer 320 is located within a cavity in the wand 310 then the end of the wand 310 where the transducer 320 is located should preferably be smooth to provide a comfortable surface for applying the end of the wand to.
