With 1046 illustrations on 355 figures, 319 pages. 1940. Philadelphia, W. B. Saunders Co. This volume provides the dentist with a comprehensive manual of roentgenologic technique for the production and processing and interpretation of dental x-ray films. In the preface to t.he book, the authors stress the need for better understanding and interpretation of roentgenograms in the following words: “It may come as a shock to some dentists, but it is a fact that a full mouth series of roentgenograms properly posed and taken with correct angulation of the x-rays for each film, invariably excites admiration among both dentists and physicians, as though some near miracle had been wrought. Such surveys should be and can be a matter of course.” Chapters are presented on every phase of roentgenographic processing technique, the complete intraoral and extraoral roentgenographic survey and orientation of roentgenograms ; stereoscopic roentgenography ; roentgenographic interpretation; dental roentgenograms of the normal child and differential diagnosis between anatomic landmarks and the indication of pathological conditions. Every phase of roentgenology is covered and excellently and profusely illustrated. Emphasis is placed on roentgenography of children both of normal and abnormal conditions. An interesting chapter is included on localization of misplaced teeth and cyst,s. Standard views taken in fixed positions are recommended as an aid in determining the locat,ion of impacted, supernumerA detailed index is ary, and unerupted teeth and pathological conditions. provided which will make it easy for the orthodontist t,o employ the book as to practitioners of a reference t,ext.
