While orthodontists have an interest in every phase of dentistry, it is worth noting that one-fourth of the 1960 Year Book deals directly with orthodontics. Noyes, the editor of the section on orthodontics, points out that interest in facial growth, development of the dentition, and appraisal of the facial profile have received particular attention during the period under review. Many articles on retention, prevention, and interceptive orthodontics are also reviewed. Removable appliances are finding wider usage, and a number of articles on the subject are included. Eleetromyography and cephalometrics are also prominent in the literature. articles have been digested on cleft palate orthodontics, habit breaking, and The number of articles on extraoral anchorage is apparent,ly serial extraction. receding.

The data presented in this book were obtained largely from Drs. Harold C. Stuart of Boston, Massachusetts, and Richard H. Stucklen of Wilmington, Delaware. The study itself was supported by a number of organizationsmainly the United States General Education Board, in the early years, and more recently the Research Grants Division of the United States Public Health Service.

Methods are presented for determining norms of dental development, including mesiodistal crown diameters, size of the dental arches, and spacing and crowding of the teeth. With regard to prediction of dental development, Moorrees found that the pattern of dental growth is peculiar to the individual and may deviate from that of the group to a marked extent. No predictions can be made from measurements in the deciduous dent,ition with respect to the permanent dentition.

The author recognizes that diseases of the mouth are as yet in an area which falls between the jurisdiction of the physician and that of the dentist. The present text presents a brief technique for practical interpretation and background explanations of conditions frequently met in the examination of the oral cavity. It is advised that during examination of the mouth attention should be given to the appearance and texture of the entire mucosa and not just of the alveolar processes. Many pathologic conditions are described and illustrated. Among the topics discussed are stomatitis, pigmentation, and foul breath. The detection of malignancies is described. The indications for the use of various drugs are mentioned. It is pointed out that adolescence is the period of greatest dental disturbances, possibly because the recent eruption of teeth has presented many susceptible areas. It is probable, also, that hormonal disturbances are at least partially responsible. With respect to orthodontics, the author directs his remarks mainly to the physician. However, the discussion should be useful to the practicing orthodontist when he is faced with a similar situation. J. A. S.

The legends that accompany illustrations should specify the patient’s position when the film was taken, that is, prone, supine, or erect. In each instance, however, the film is presented for viewing as if the reader is looking In other words, the right side of the patient is at the front of the patient. to the left of the reader and vice versa. In the descriptive portions of legends,when “right” is mentioned reference is made to the right side of the patient and not to the right side of the reader. Similarly, the terms “medial” “mesial” and “lateral” refer to the midline of the patient The reprog&ions should have the same tones as the original film that is’ a black area in the original film is also black in the illustration. tihen ai “increase in density ’ ’ is mentioned, this refers to an area in the illustration which is Areas in illustrations and in original films whiter than would be anticipated. which are blacker or darker are referred to as more “lucent” regions. This method of designation is consistent with the degree of absorption of the x-ray beam in the various portions of the body; a whiter area (“increase in density”) refers to an area of greater x-ray absorption in the body and a darker area (“decrease in density”) refers to an area. of diminished x-ray absorption. The term “density,” used in this fashion, does not refer to the physical density of the film.
