DR. SMITH:—My method of using porcelains is so similar to what Dr. Stoddard has just presented that my remarks will be largely an endorsement of his paper. I do only the operative part; the laboratory part is done by my assistant, so I have only that part requiring the shaping of the cavity and taking the impression. I have a number of questions I want to ask Dr. Stoddard on working his furnace, but that hardly comes in to what you would call discussion. I like the method I have used, that is, taking an impression of the cavity, baking the enamel and setting in cement or gutta-percha. I have also ground them in, and, as Dr. Stoddard says, it is a very difficult thing to grind them in entirely. Even a very large cavity will seem very small when you get the porcelain between your fingers and attempt to grind it into place. I think it is a much better way to take the impression and bake the body and enamel it, as Dr. Stoddard has suggested. I would further say, Mr. President, that I am using the porcelains where we find large cavities in molars: for instance, dead teeth, where we have a compound cavity, either the mesial or distal surfaces in connection with the crown, and where amalgam is prohibited and the teeth too weak for gold. I find that when an impression is taken of the cavity, and the filling made as Dr. Stoddard says in his paper, and set in cement, that it makes a very nice-looking filling, and one that wears exceedingly well. I use the porcelain in that way a great deal and obtain from it success and satisfaction. DR. TAFT:—There is but little I can say on the subject before us, from the fact that I have had no experience whatever in making porcelain fillings; although so frequently do cases present themselves in my practice, where porcelain tips and inlays would no doubt make not only as durable but more artistic fillings, by far, than gold or any of the plastics, that I feel encouraged to adopt this method after listening to the interesting paper of the evening, and upon examination of the specimens before us. In looking over the specimens I notice quite an appreciable difference in color between the inlay and the tooth itself, more so in some than in others. This may, of course, be due to the fact that possibly the inlays were placed in some of them previous to extraction. I do not yet quite understand how the doctor mixes his material so as to get the color of the inlay as nearly like that of the tooth as is possible, and should like to have him explain the point a little more thoroughly. DR. STODDARD:—I neglected to say that it was impossible to match the color of these dry, dead teeth out of the mouth, but there is no difficulty at all in the mouth. You have a baked sample of your body, which you keep, and from which you select your color.
