COMBINATIONS FOR FILLING TEETH. 13 I filled cavities about two-thirds full with tin,and finished with gold. (S. S. Stringfellow,American Journal of Dental Science, 1839.) Tin foil is greatly used by some American den-tists, but it is not much better than lead leaf.(Surgical, Operative, and Mechanical Dentistry,L. Charles De Londe, London, 1840.) *Tn 1841 there were about twelve hundred den- FlG. tists in the United States, many of whom wereusing tin, and there are circumstances under whichit may be used not only with impunity, but advan-tage, but it is liable to change. (Harris.) I ,put in tin fillings, and at the end of thirtyyears they were badly worn, but there was nodecay around the margins. (Dr. Neall, 1843.) In 1843 Dr. Amos Westcott, of Syracuse, N. Y., 14 TIN FOIL AND ITS filled the base of large cavities with tin, completingthe operation with gold. Tin is used in the form of little balls, or tubes,but folds are better; introduce the metal gradually,taking care to pack it so that it will bear equallyupon all points; the folds superimpose themselvesone upon the other; thus we obtain a successivestratification much more exact and dense, and it isimpossible there can be any void.
