Annual
The Awnual Review of Physiology was initiated in 1939, and since that time the publication has become a standard work of reference on the contributions to this field. While many foreign periodicals are still unavailable and many of the interests of physiologists were on wartime ban during the preparation of this volume, there are, nevertheless, a number of new contributions ‘which should prove of interest; some of them will be found of special interest to the dentist and orthodontist. Authors of the various articles have included their own interpretation of publication data and, on occasion, have even departed from the conclusions of others. In accounts presented in papers by Lasker in which evidence is given of the wide range of plasticity of the human skeleton, including the teeth, dental caries is shown to be subject to environmental influences. No racial trend could be detected in the teeth although the shape of the upper incisors is so strongly genetic as to show distinctive differences in the various regions of a country. The section on developmental physiology discusses the correlation of form and function. Important contributions are presented on congenital malformations in which dietary deficiencies of the mother are shown to be responsible for congenital malformations. The pH of saliva was found to have relationship to seasonal fluctuations and even to hourly fluctuation. A new method was presented for determining the amylatic activity of saliva. Considerable difference in pH was found although there was no correlation between these pH readings and the amount of caries. However, the diastatic index of saliva was found to be universally related to the amount of caries. No lactobacilli were found in stool specimens from children whose teeth were free from caries. During this period the presence of lactobacilli was only occasionally recorded in the saliva of these subjects. This is a valuable book and it contains much of Author and subject indexes interest to students and practitioners of dentistry. are provided. Applied Anatomy of the Head and Neck for Students and Practitioners of Dentistry: By Harry H. Shapiro, D.M.D., Assistant Professor of Anatomy, College of Physicians and Surgeons, Columbia University. Second edition, revised and reset with 221 illustrations including 41 in color. Philadelphia, J. B. Lippincott Company, 1947. Shapiro has effected changes in the present edition so that it is practically a new book. While the original purpose of the book-to correlate anatomic instruction with clinical application-has been preserved, the material presented in the second edition has been thoroughly revised and many new chapters have been added. Among the new material are chapters on development of the head and neck, the paranasal sinuses, the anatomy of oral infections and of the edentulous mouth. In each instance the clinical application is presented. Additional material is presented on interpretation of the anatomic landmarks as seen in roentgenograms of the skull. Included also is the roentgenographic interpretation of tooth development, the temporomandibular joint, the sinuses, and other structures. Anatomic considerations of jaw fractures and the control of hemorrhage and infection are duly explained.
