Dental ese fillings absolutely without anyundercuts, but I find in my hands that I can put in gold fillings thatlook pretty fair to me, and that suit my patients pretty well, and they 28 THE DENTAL SUMMARY have stood the test of eight years, and they still look pretty fair. Itis true, some of them have failed, due probably to my own fault, per-haps to my methods of manipulating the gold, points that I have,maybe, passed over, or points in the cavity preparation that I havenot prepared as I should have. We all overlook those at times, butI would rather have a slight undercut—not in the sense of a deepundercut—but you understand, this must come in the dentine. Wemust not have the enamel rods exposed at that point, but the enamelrods must be supported by the dentine at that point, so that in themovement of your plugger point in condensing that gold you are notgoing to fracture any enamel rods. But even if the enamel rods arepowdered at that point it does a great deal less harm than it would. at the margins. That is what I mean by a retentive form, as youwould call it, or undercuts, as I would call it. They are undercuts!Why? Because the distance from A to B is less than it would befrom C to D, and a filling driven into those points and thoroughlycondensed can be condensed over the margin without the danger ofmovement or rocking of the filling, and it is because of the successthat I have had in this method of putting in my fillings that I stillhang to it. When I am fully convinced and shown that I can fill cav-ities just as well without those grooves I will be glad to do it be-cause I can do it quicker. Dr. Nason, Omaha, Neb.: I would not let this go by withoutcorrecting the gentleman just a little bit. I have filled with softgold for 15 or 20 or 30 or 40 years, more or less. Now I alwaysround this out, but use the flat seat. I dont believe that you under-stood Dr. Woodburys preparation for retention. For instance, now,his idea is this step, he calls it,
