Baccetti and Franchi report on their studies demonstrating that the optimal time for treating a Class II skeletal disharmony with a functional appliance (Twin-block or FR-2) is during or slightly after the peak of mandibular growth, as revealed by a biologic indicator of skeletal maturity such as the cervical vertebral maturation method. This developmental period correlates with the greatest potential for producing a favorable modification in the facial profile by dentofacial orthopedics. The stages corresponding to 6 different maturational phases in the cervical vertebrae during the prepubertal period are shown in line drawings. In the final essay, “Recent progress in integrated threedimensional craniofacial mapping at CRIL/UP,” Baumrind outlines the current investigations in 3-dimensional craniofacial measurements at the University of the Pacific’s School of Dentistry. Briefly reviewed are answers to questions about why should orthodontists be interested in 3-dimensional craniofacial measurement, what is the basic theory underlying noncontact 3-dimensional measurement from images, and what are the recent advances in measurement technology that will improve our chances of generating precise 3-dimensional skull and face measurements. The 13 papers by 24 contributors contain a wealth of clinically useful information for orthodontists and other dental specialists as well as craniofacial biologists.

Dorland’s Pocket Medical Dictionary was first published 102 years ago. Since then, over 8100 terms have been added, and according to the publisher, more than 2800 have been selected for addition to this new edition. Particular attention has been paid to pharmaceutical terms, concentrating on drugs marketed in the United States; almost 500 new drugs have been added. To keep the book from expanding to where it is no longer compact or pocket-size, more than 1600 outdated or less valuable terms have been deleted. Similarly, listings for many outdated or rarely used drugs have been removed.

The updated book is compact, rugged, and conveniently indexed. The terms and definitions are brief, but adequate, and to the point. The print on the thin yet opaque white pages is crisp and easy to read. The binding and flexible cover are designed to take a lot of use. Every health professional should have ready access to a medical dictionary; this is a good one to own at a reasonable price.

THESIS ABSTRACT

Evaluation of an original CD-ROM for teaching cephalometric radiography Michael Thomas Henry, DDS College of Dentistry, The Ohio State University, Columbus, Ohio

The graphic program Authorware was used to generate an original CD-ROM, to serve as a self-instruction tool for teaching cephalometric radiography. Level 1 and level 2 formats were established to make this multimedia interactive computerized module suitable for both the predoctoral dental student and the postdoctoral dental specialist. It was necessary to test the CD-ROM with predoctoral dental students to validate it as an educational tool. This educational module was made available to, and evaluated by, a group of sophomore dental students at The Ohio State University College of Dentistry as part of a randomized trial. The study was designed to test the effectiveness of the CD-ROM multimedia format versus the standard lecture format in the predoctoral orthodontic curriculum. The class was divided by stratified random sampling into 2 groups, the lecture (n = 43) and the CD-ROM (n = 41), matched on the basis of grade-point average and gender. Pretest and posttest examinations were given to provide a baseline assessment of each student’s knowledge and to establish a measure for improvement. Results indicated no statistically significant difference between the 2 groups in GPA, gender, or pretest-to-posttest changes in scores. The students found the CD-ROM enjoyable to use and easy to navigate through and thought it would be conducive to better retention of the material. 0889-5406/2001/$35.00 + 0 8/3/118230 doi:10.1067/mod.2001.118230
