Histopathology of the Teeth and their Surrounding Structures [antikvár]

PREFACE TO THE SECOND EDITION. This book has been enlarged, rearranged, and completely rewritten for the second edition. The subjects have been grouped somewhat differently, as suggested in the Report of the Curriculum Survey Committee of the American Association of Dental Schools. More than before, an attempt has been made to omit controversial and, to the tyro, rather inconsequential details, and as far as possible to oífer an unbiased survey of present-day knowledge of the various subjects. The chapter on the Histology and Physiology of the Dental Tissues has been omitted because its contents were since enlarged and incorporated in the author's Dental Histology and Comparative Dental Anatomy. The chapter on Histological Teehnique has been dropped since it is outside the sphere of interest of the dental student and practitioner; those interested in the preparation of specimens of the type illustrated in this book are referred to the artiele, "A Teehnique for the Preparation of Histologic Sections Through Teeth and Jaws for Teaching and Research" in the Journal of Dental Research, June, 1937. Among the chapters or subjects included in this new edition are: anomalies in shape and number of teeth; physiology and pathology of tooth calcification; Hutchinson's teeth and mottled enamel; erosion; bacteriology of caries, pulpitis, and periodontitis; focal infection; pulp amputation; healing of extraction wounds; Vincent's infection; discolorations and stains; somé of the diseases of the oral mucosa; tumors of the oral cavity; and differential diagnosis of toothache and of cysts of the jaws. The number of illustrations has been increased from 385 to 438. The bibliography is confined to fairly recent publications that can be easily secured; most of the articles cited contain all the needed references to earlier publications on the particular subject. The author is greatly indebted to The Foundation for Dental Research of the Chicago College of Dental Surgery under whose auspices nearly all our recent research work has been carried out, and to the Chicago College of Dental Surgery, Dental Sehool of Loyola University, from whose Research Department most of the findings reported in the first edition originated.
