ABSTRACT:
A unique dental spatula includes an angle head, and an elongate body having a plurality of lateral projections forming apertured posts for affixing and displaying color-shade samples. The spatula portion of the instrument has an angled head so that the instrument can be conveniently held for spatulation or for holding the color samples adjacent to the patient's teeth to visually determine the proper color match. The elongate handle portion of the present invention is made of a clear material so that it does not affect resin coloration and further includes a roughened front surface for retaining written indicia, which serves to denote the particular proportions of material used in a given sample.
