     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 10 thereof, a new and improved dental eye shield apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the dental eye shield apparatus 10 of the instant invention essentially comprises a polymeric flexible arcuate shield plate 11 formed of a transparent material, including a linear top edge 12 and including respective first and second side edges 13 and 14 arranged in a spaced relationship relative to one another and extending downwardly relative to the top edge 12. A convex lower edge 15 extends from lower distal ends of the first and second side edges 13 and 14 and includes a concave recess 16 oriented medially of the convex lower edge 15 projecting into the shield plate 11 to accommodate an individual&#39;s nose therewithin. A nasal mask 17 in pneumatic communication with a source of dental gas, such as nitrous oxide, includes pneumatic hoses 18 directed into the nasal mask, with the nasal mask 17 having its outer surface secured to the shield plate 11, and more specifically within the concave recess 16 by a plurality of L-shaped support tabs 19, with each support tab including an adhesive surface 20 for securement of and mounting to the outer surface of the nasal mask 17, with the adhesive surface 20 secured to a lower leg 19a of each support tab 19. 
     The use of a modified shield plate 11a further includes a flexible web 22 mounted to the shield plate&#39;s outer surface 21, with the flexible web 22 including a gelatinous coating 23 mounted coextensively to the flexible web 22 to receive and arrest airborne particles within the gelatinous coating 23 resultant from a dental procedure. Such particles are typically of tooth and/or filling structure such as to include silver and the like and may be subsequently disposed of by removal of the flexible web 22, in a manner as illustrated in FIG. 6, as the flexible web 22 is adhesively secured by transparent adhesive to the shield plate&#39;s outer surface 21. 
     The shield plate 11a further includes in the apparatus illustrated in FIGS. 9 and 10 an arcuate slot 24 directed through the shield plate 11 in spaced adjacency to the concave recess 16. A first link and a second link 25 and 26 respectively are pivotally joined relative to one another by a link axle 27 intermediate the first and second link end portions. A first link guide chute 28 and a second link guide chute 29 are mounted to the upper distal end of the first and second links 25 and 26 and secure the upper ends of the first and second links within the arcuate slot 24. Lower distal ends of the first and second links include respective first and second link mounting feet 30 and 31, with the mounting feet 30 and 31 including the aforenoted adhesive surface 20, with the adhesive surfaces 20 oriented substantially orthogonally relative to the first and second links 25 and 26 to permit accommodation of masks of various geometric configurations. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
