Defects in the enamel, such as pits or grooves, can be imitated by drilling the enamel surface of a tooth and staining with the desired color. The pink or gum color will be found very useful in covering platinum bands which are exposed below the gum line, also in coloring that portion of an inlay or crown which must match the cervical border of ad- joining teeth. Before attempting to apply the stains, the teeth should be made perfectly clean and dry. If they are to be aged they should be set up, articulated, and ground upon the cutting edges and articulating sur- faces, then removed one by one and stained. In applying the stain it is important to mix the material until it works smoothly and to a consistence which will permit it to be used after the manner of paint. When so mixed, the stains may be applied with a small, pointed camel's-hair pencil, and then distributed over the surfaces of the teeth by means of the fingers or a stippling brush. If a.wavy, granu- lated effect is desired, the material should be applied rather thick; but as generally required, it should be laid on very evenly and in thin layers, thus producing a suggestion of color rather than a decided effect. In cases calling for a decided blue at the cutting edge, a milk spot in the labial surface, or the effect of exposed dentin, it is advisable to make a recess in the enamel of the tooth with a diamond disk or drill and then fill this recess with the stain.
