Restorative dental materials
Am. J. Orthod. February 1977
part per million of fluoride in the drinking water of children, especially before the permanent teeth erupt. Under “Anesthesia” are discussed the different stages experienced by the patient undergoing inhalational and intravenous anesthesia. The effects of aspirin on the prolongation of clotting time for extended periods of time is considered. “The metabolic fate of local anesthetics,” according to Murdoch of Pale and Peter Cohen of the ITniversity of Colorado School of Medicine, “is of great practical importance because their rate of absorption varies greatly and is an important factor in determining their safety.” This encyclopedic work of 1,700 pages will be found indispensable by those who are interested in knowing the influence of the drugs they prescribe for their patients.

This edition, like those which preceded it, is intended to provide dental students with information on the behavior of dental materials and an understanding of the basis of the technical procedures in their manipulation. Chapters are provided on the fundamental physical and biophysical properties of materials used in dental practice. Resilience of wires used in orthodontics is discussed in some detail. It is pointed out that the resilience of a wire is important in estimating the amount of activity that can be expected of it in moving teeth. Of interest to orthodontists also is the amount of strain and stress produced and the proportional limit possessed by wires in order to determine the magnitude of the force that can be applied to teeth and how far teeth will have to move before a spring is no longer effective. Soldering of stainless steel wires is explained, and the harmful effects of improper cleaning and polishing of steel wires are stressed. Orthodontists will find in this volume useful information on the materials they use, whether impression materials, plastics, or metals. b. A. Salzmann
