In accordance with one embodiment, a vibratory transducer has an armature suspended in a magnetic field. The armature has a plurality of electrical conductive paths to provide electrical current flow in said armature to react with said magnetic field and cause movement in the armature controlled by variation in the electrical current flow. A contact surface is secured to the armature, with a surface area for frictionally coupling to a corresponding surface area of a patient for example. Movement of the vibratory transducer induces movement in the patient, and the transducer can produce movement in the contact surface in at least two dimensions simultaneously. In one embodiment the contact surface is flat, while in alternative embodiments the contact surface is incorporated in a toroidal structure so as to surround part of the patient. Medical application can include treatment of bone fractures, oedema, and in elastography, amongst other applications.

In the inventive method, a tooth whitener having a concentration of hydrogen peroxide significantly lower than the concentration typically used in in-office applications is applied to the teeth in gel form. Next, thin transparent film is placed over the teeth to seal the tooth whitener onto the teeth. The film creates a closed system that precludes oxygen from migrating away from the teeth into the atmosphere. A white light in the range of 380-660 nm wavelength is then activated to assist in exciting oxygen in the path of the light and the oxygen molecules bombard the tooth surfaces. The oxygen molecules may not easily escape from the tooth surfaces into the atmosphere due to the wrap and, thus, their whitening “power” is enhanced and lengthened. Then, the patient may stabilize the whitening results over a 7 to 10 day regime using a lower concentration tooth whitener.
