     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to medical drilling techniques and, more particularly, to a system for introducing conditioned fluids into the drilling techniques. 
     2. Description of Related Art 
     Water is generally used in a variety of cutting operations in order to cool the target surface. Additionally, water is used in mechanical drilling operations for cooling the target surface and removing cut or drilled materials therefrom. Many prior art cutting or drilling systems use a combination of air and water, commonly combined to form a light mist, for cooling a target surface and/or removing cut materials from the target surface. The use of water in these prior art systems has been somewhat successful for the limited purposes of cooling a target surface or removing debris therefrom. These prior art uses of water in cutting and drilling operations, however, have not allowed for versatility, outside of the two functions of cooling and removing debris. 
     SUMMARY OF THE INVENTION 
     According to an aspect of the present invention, a handpiece is constructed to have a proximal end and a distal end, with the distal end including a source of mechanical tissue disruption that is configured to treat or ablate a target surface. The source of mechanical tissue disruption includes a tissue-disrupting distal end, and the handpiece further includes a flavored particle output for directing flavored particles in a direction toward the tissue-disrupting distal end. Another feature of the present invention includes a handpiece having a proximal end and a distal end. The distal end of the handpiece includes a source of tissue displacement that is configured to move or displace a portion of the target surface, and that is formed to have a tissue-displacing distal end. The handpiece, furthermore, can be configured to have a flavored particle output for directing flavored particles in a direction toward the tissue-displacing distal end. The present invention, together with additional features and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying illustrative drawings.

     DETAILED DESCRIPTION OF THE PRESENT INVENTION 
     Reference will now be made to certain embodiments (e.g., certain described and/or incorporated embodiments) of the invention, partial examples of which are illustrated in the accompanying drawings. Wherever possible, the same or similar reference numbers are used in the drawings and the description to refer to the same or like parts. It should be noted that the drawings are in simplified form and are not to precise scale. In reference to the disclosure herein, for purposes of convenience and clarity only, directional terms, such as, top, bottom, left, right, up, down, over, above, below, beneath, rear, and front, are used with respect to the accompanying drawings. Such directional terms should not be construed to limit the scope of the invention in any manner. 
     Although the disclosure herein refers to certain embodiments, it is to be understood that these embodiments are presented by way of example and not by way of limitation. The intent of this disclosure, while discussing exemplary embodiments, is that the following detailed description be construed to cover all modifications, alternatives, and equivalents of the embodiments as may fall within the spirit and scope of the invention as defined by the additional disclosure in claims format. It is to be understood and appreciated that the process steps and structures described herein do not cover a complete architecture or process, and only so much of the commonly practiced features and steps are included herein as are necessary to provide an understanding of the present invention. 
     As depicted in the attached figures, in connection with certain aspects of the present invention, a drill assembly is provided with a source of flavored fluid particles. As depicted in the attached figures, in connection with other aspects of the present invention, a drill assembly is provided with a source of flavored fluid particles and also with a source of electromagnetic energy. In particular,  FIG. 1  illustrates a drill assembly that is provided with a source of fluid particles according to embodiments of the present invention. The drill assembly can comprise one or more drills  5 , one or more first outputs  9 , one or more second outputs  12 , one or more third outputs  15  and one or more fourth outputs  22 . Each, or any number of, the outputs can be configured and oriented for directing one or more of (a) any electromagnetic energy described or referenced herein, (b) a liquid, (c) a gas, and (d) a combination of gas and liquid, toward the distal region  25 . The elements  5 , the fluid, and electromagnetic energy can comprise any characteristics described and referenced herein (e.g., drill can be transparent or have a shaped region  25  for ablating, etc.). In one implementation, a first handpiece comprises a drill  5 , output  9  and output  12 , and a second handpiece comprises a second drill  5  (symbolized as the right part of the phantom line, although the drills  5  and second drill  5  would of course not touch, being part of different handpieces), a second output  15  and a second output  22 . 
     According to one broad aspect, rather than or in addition to a drill assembly, a source of mechanical tissue disruption is provided with the same or an additional/alternative source of flavored fluid particles. The source of mechanical tissue disruption can be configured to treat or ablate a target surface. Furthermore, the source of mechanical tissue disruption can comprise a tissue-disrupting distal end that performs one or more of contacting the target surface and effectuating ablation of a portion of the target surface. 
     According to another broad aspect, rather than or in addition to the drill assembly, a source of tissue displacement is provided with a source of flavored fluid particles. The source of tissue displacement can be configured to effectuate one or more of contacting the target surface and moving or displacing a portion of the target surface. Furthermore, the source of tissue displacement can comprise a tissue-displacing distal end that contacts the target surface and moves or displaces a portion of the target surface. 
     The source of flavored fluid particles may also be provided with, in certain implementations, a source of electromagnetic energy, which may comprise laser energy and/or visible light and may operate to provide or promote one or more of desterilization, bacterial reduction, biostimulation (e.g., low-level light therapy), coagulation, remodeling, caries detection or treatment, and illumination (e.g., with visible light). 
     The handpiece may comprise a dental handpiece with a dental tip (e.g., comprising a dental drill). 
     In one implementation, a drill may be configured with a source of flavored fluid particles and further (a) may be configured with an electromagnetic energy source of ablation, and/or (b) the same drill or an alternative drill may be configured with an electromagnetic energy source of illumination, and/or (c) the same or an alternative drill may be configured with an electromagnetic energy source of tissue disruption, and/or (d) the same or an alternative drill may be configured with an electromagnetic energy source of biostimulation. The drill may comprise, according to one implementation, a dental drill for cutting oral tissue. 
     The target surface may comprise, for example, one or more of tooth tissue, bone, cartilage and soft tissue such as skin. 
     According to certain aspects of the present invention, an energy output can be configured to emit electromagnetic energy, which can comprise one or more of hard-tissue ablating electromagnetic energy, low-level light therapy (LLLT) electromagnetic energy, tissue-biostimulation electromagnetic energy, visible electromagnetic energy, coherent light, one or more of a wavelength within a range from about 2.69 to about 2.80 microns and a wavelength of about 2.94 microns, and electromagnetic energy generated by one or more of an Er:YAG laser, an Er:YSGG laser, an Er, a Cr:YSGG laser and a CTE:YAG laser. 
     The assembly can comprise a fluid port disposed at a first location of the distal end of the handpiece for emitting the flavored fluid particles, and another structure (e.g., port that can accommodate a powered rotating shaft for, as an example, a drill) at a second location of the distal end of the handpiece can be provided with the tissue-disrupting end or the tissue-displacing distal end. 
     The assembly can comprise a handpiece. The handpiece can further comprise an electromagnetic energy output configured to emit energy in a vicinity of the distal end of the handpiece. 
     In one implementation, the electromagnetic energy output can be configured to direct electromagnetic energy in a direction toward the tissue-disrupting or the tissue-displacing distal end. For example, a electromagnetic energy port(s) can be provided at one or more of the first location, the second location, and a third location. The electromagnetic energy port(s) can be the same as or different from the above-mentioned fluid port at the first location and/or the above-mentioned structure at the second location, and the electromagnetic energy port(s) can be provided with or without the flavored particle output and/or the structure being located at the respective ports or port vicinities. 
     The flavored fluid can be a flavored liquid. In certain implementations, the liquid is or comprises flavored water. 
     According to other implementations, the apparatus comprises a fluid output that is configured to emit fluid, which may be the flavored fluid particles and/or other fluid, in a vicinity of the distal end of the apparatus, wherein: the fluid output comprises an atomizer configured to place atomized fluid particles into a volume above the target surface; and the energy output is configured to impart relatively large amounts of energy into the atomized fluid particles in the volume above the target surface to thereby expand the atomized fluid particles and impart disruptive forces onto the target surface. The other fluid may be or may comprise conditioned fluid or conditioned fluid particles, as described or referenced in any of the below-cited documents. 
     In certain implementations, the tissue-disrupting or the tissue-displacing distal end (e.g., drill end) may be able to ablate or remove the target surface (e.g., hard tissue) better than a laser. According to other implementations, the tissue-disrupting or the tissue-displacing distal end (e.g., a drill end or a side-firing drill end) may be able to access, for example, sidewalls within a lumen, channel, pocket, etc. of the target and/or remove the target surface (e.g., hard tissue) better than a laser. 
     In still other implementations, the tissue-disrupting or the tissue-displacing distal end (e.g., a drill end or a side-firing drill end) may comprise a clear material and/or a material that is transparent to one or more wavelengths of the electromagnetic energy. For instance, the tissue-disrupting or the tissue-displacing distal end may comprise one or more of sapphire, diamond, and a ceramic material. The attached figures elucidate exemplary tissue-disrupting or tissue-displacing distal ends.
