652 counted as negative. Statistical analysis studied the data for relationships between markers and student ages, ethnicity, sex, birthplace, and laboratory testing site. Serum was tested from 4,936 students (21% of all Honolulu students in the studied grade levels). The rate of participation varied from school to school (11% to 4 1%). There were slightly more females than males (51.5%). A total of 353 students (7.15%) had serologic evidence of HBV infection. The incidence increased from elementary school up to high school age. Sixty three students tested at one laboratory were anti-hepatitis B surface antigen positive (2.9%) but had no evidence of current infection. None had been vaccinated. The data from the second laboratory yielded similar results. Eighty three students (1.68%) were identified as HBV carriers. The highest rates were found among Indochinese, Korean, Chinese, and Samoan students. Many of these had been born in Asian or Pacific islands other than Hawaii. The rates were higher than in those born in the United States. The authors concluded that horizontal transmission of HBV occurs in Honolulu school-age children, and that it will be necessary to routinely immunize all infants and children in Hawaii, not just those born to carrier mothers, to reduce the incidence of HBV.R.E.

LITERATURE

internal derangements. the third section provides a detailed review of conditions other than internal derangements, the fourth section deals with arthroscopic diagnosis and treatment, and the final section describes an organized scheme for selecting the appropriate diagnostic imaging procedure. While stressing the value of imaging as a diagnostic aid, the authors emphasize the need to combine these procedures with thorough clinical evaluation and good clinical judgement. Pocket Atlas of Pharmacology. Lullmann H, Mohr K, Ziegler A, et al. New York, NY, Thieme, 1993, 374 pages, 149 color illustrations, paperback.

This pocket atlas is designed to enable the reader to quickly acquire basic pharmacologic information. The first part deals with principles such as drug absorption, distribution, and elimination, as well as with concepts of molecular mechanisms of drug action. The second part discusses the different groups of drugs, with emphasis on their functional and therapeutic aspects. The final part provides information on the pharmacotherapy of specific diseases. The book is extensively illustrated with color diagrams emphasizing various aspects of drug action and pharmacokinetics. Contemporary Oral and Maxillofacial Surgery (ed 2).

New Book Annotations Managing TMJ Pain. Wappcl FG. Oak Forest, IL, Therapeutic Media, Inc, 1993, 87 pages, illustrated, $10.00, paperback.

The intent of this book is to teach patients how to modify daily habits, make changes in lifestyle, and perform exercises that will make daily activity easier and more comfortable. Included are chapters on causes of temporomandibular joint (TMJ) pain and dysfunction, anatomy, posture and postural habits, body mechanics and ergonomics, diet and nutrition, exercise, and stress management. It is designed to be used in conjunction with the recommendations of the practitioner and not as a substitute. Biomechanical Design of a Total Temporomandibular Joint Replacement. Falkenstrom CH.

Based on an evaluation of TMJ histology, physiology, biomechanics, and a three-dimensional mathematical analysis of functional load, specifications for the design of a new TMJ prosthesis are proposed. It consists of a poly-articulation system that allows rotation and mediolateral translation without disturbing the contralateral joint, and with the introduction of minimal friction and wear. Recommendations for methods of fitting and fixing the prosthesis are also made. Diagnosis of the Temporomandibular Joint. Katzberg RW, Westesson PL. Philadelphia, PA, Saunders, 1993,4 19 pages,

387 illustrations, $125.00. This book provides a comprehensive overview of the imaging techniques used for the diagnosis of diseases of the TMJ, with special emphasis on internal derangements. The first section describes normal and abnormal anatomy, the second section discusses the various imaging modalities for

In this second edition, various aspects of the book have been updated and many chapters have been revised or rewritten. The section on principles of surgery now includes the latest recommendations regarding disease transmission, the section on preprosthetic surgery places increased emphasis on dental implantology, and the sections on pathology, trauma, dentofacial deformities, and facial pain have been revised to reflect current progress in these areas. Although designed primarily as an instructional text for dental students. it also contains useful information for the resident and specialist in oral and maxillofacial surgeon. Joint (ed 2).

In harmony with the changes in the field, this second edition places greater emphasis on the significant advances in diagnostic and therapeutic arthroscopy. A detailed chapter on various TMJ implants has also been added that provides information on joint mechanics, jaw kinematics, mechanical testing, and tribology. The other chapters have been revised and updated. Computers in Clinical Dentistry. Preston JD (ed), with 35 contributors. Chicago, IL, Quintessence, 1993, 228 pages, illustrated, paperback.

This book contains various papers presented at the First International Conference on Computers in Clinical Dentistry held in 199 1. The material is categorized into sections on office management systems, clinical charting systems, mandibular movement analysis, periodontal devices, radiographic imaging, CAD/CAM, and expert systems applications. The authors represent those persons currently actively involved in the development and use of computers for dental applications.
