Dental laser brushing or cleaning device
First Claim
1. A cleaning device to clean teeth, gums and other oral areas comprising:
- a handle, a brushhead, a radiation source, and a power source for said radiation source;
said brushhead further comprising a backing plate and a multiplicity of bristles;
said radiation source being a diode lasera delivery means for said radiation;
said delivery means for said radiation comprising an optical fiber optically connected to said radiation source;
said optical fiber being terminated such that said optical fiber'"'"'s longitudinal axis is substantially directed at an opening in said brushhead;
said opening allowing passage of a liquid and radiation to oral areas to be cleaned;
a tube providing passage for liquid under pressure;
said optical fiber having a termination-tip which forms a substantially flat surface relative to said optical fiber'"'"'s longitudinal axis;
said tube having an open-end substantially near said termination-tip;
said liquid coming through said open-end passing over said surface of said termination-tip;
an angle formed between said surface of said termination tip and said optical fiber'"'"'s longitudinal axis forming a substantially refractive surface for said radiation while liquid is passing over said surface and then to said opening thereby passing said radiation substantially through said opening; and
said angle forming a substantially reflective surface for said radiation when said liquid is not passing over said surface, thereby passing said radiation substantially to said brushhead.

Abstract
The invention is an oral cleaning device incorporating a low power laser radiation source and means for producing pulsed or continuous wave delivery of low power radiation to teeth, gums and oral tissue. The device is used alone or in conjunction with a liquid jet or jets and/or with photosensitizer dental paste or liquid. The device destroys bacteria and viruses in the mouth and on surrounding tissue. It increases oral blood circulation and enhances the body'"'"'s immune system response to oral infection. The device may be operated by a trained professional at three different repetition rate frequencies, selected by the operator to threat different dental conditions. The specific photosensitizer liquid or paste which is activated at a certain wavelength is chosen by the operator to treat different dental conditions. The device is also intended for home dental hygiene at low power.
