A dental burr holder comprising a holder body adapted to rest on a support and having a smooth, upper surface interrupted by a plurality of upwardly opening burr receiving apertures, and a member projecting generally upwardly from the holder body and having a smooth front surface which faces across the upper surface of the holder body. These two surfaces form a background which color contrasts with the burrs and against which the burrs are viewed. The background is continuously color contrasting and is substantially visually uninterrupted except for the burr receiving apertures. This structure allows quick and accurate selection of the desired burr silhouetted against the contrasting background, and also makes the problem of detecting damaged or imperfect burrs easier. With dark colored burrs, a white background is preferred.

A dental burr holder comprising, in combination: a holder body adapted to rest on a support and having a smooth upper surface interrupted only by a plurality of upwardly opening burr receiving apertures; and a member rigidly coupled to and projecting generally upwardly from said holder body without a space in between and having a smooth front surface which faces across said upper surface of said holder body, said upper surface and said front surface forming a background which color contrasts with the color of the burrs received in the apertures, and against which the burrs are viewed, said background being continuously color contrasting and substantially visually uninterrupted except for said burr receiving apertures to allow quick and accurate selection of the desired burrs adapted to be received in the holder and silhouetted against said contrasting background, said upper surface of the holder body forming an acute angle with a horizontal plane from 0°to about 10°.
