Early Treatment
of Cleft Lip and Palate
Proceedings of the Third International Symposium Sept. 27 to 29, 1984, University of Zurich, Switzerland Toronto, 1986, Hans Huber Publishers
The book is a summary presentation of the Proceedings of the 1984 Symposium on “Early Treatment of Cleft Lip and Palate,’ ’ which was the third in a series of similar meetings (Zurich University, 1964; Chicago, 1969) in which experts in the fields of orthodontics, maxillofacial surgery, plastic surgery, ENT surgery, and speech pathology were invited from all over the world to discuss the primary approaches to cleft lip and palate problems. Longitudinal documented information from individuals and teams from clinics throughout the world are included in the volume with alternative approaches to treatment. The concise presentations report the negative as well as the positive aspects in the evolution of their treatments by the respective groups or individuals. The international flavor of the meeting is clearly evident from the list of contributing teams, which stem from New Zealand, Switzerland, Germany, Wales, U.S.A., France, Denmark, England, Sweden, Finland, South Africa, Yugoslavia, Israel, Australia, China, Canada, and Austria. Although consensus of opinion does not necessarily prevail, from the discussions at the end of each session it would appear that barriers insulating the diverse thinking of the many different groups have been overcome. For those clinicians, particularly orthodontists and oral surgeons who are involved in the treatment of cleft lip and palate patients, the volume is almost mandatory reading. Alex Jacobson
A Manual
of Pedodontics
R. J. Andlaw and W. P. Rock Edinburgh, 1982, Churchill Livingstone, Inc.
This manual is oriented to the British undergraduate student and practicing dentist. Emphasis is on ideas and
treatments in the United Kingdom with the deliberate exclusion of etiology, clinical features, histopathology, and oral surgery. Clinical techniques are in tables modified from Task Analysis of Procedures in Pedodontics (Dr. Milton Houpt, U.S. Public Health Service, 1975). The six parts contain 30 sections that very briefly cover office protocol, behavior management, prevention of caries, treatment of minor abnormalities of the primary and mixed dentitions, common oral soft-tissue lesions, and treatment of trauma to teeth. The manual is illustrated with clear line drawings. The latest references are from 1980. Non-British readers will find this manual of interest as a concise overview of U.K. treatment choices versus those “not in vogue in the U.K.” The text is best in its discussion of caries prevention, which is not surprising considering the excellent research these educators have done in that area.

Research abstracts TMJ Tissue Reactions Following Guidance of the Mandible
Retrusive
A. lsberg and G. lsacsson Dept. of Oral Radiology, Stomatology, and Physiology, School of Dentistry, Karolinska Institute, Stockholm, Sweden (From J. Dent. Res. vol. 64, 1985.)
In order to study TMJ reactions following retrusive guidance of the mandible, 11 adult Macaca fascicularis monkeys were used; 4 experimental and 7 controls. The interference between intercuspal position and centric relation was eliminated in the experimental animals. Bilateral interferences were introduced to achieve retrusive guidance of the mandible into centric relation at mouth closure. The experimental period lasted for 5 weeks. The joint specimens were histotechnically processed and sagitally sectioned. Contrary to untreated animals, the cartilage layer of the posterior part of the condyle increased in thickness. The posterior disc attachment exhibited an increased amount of dilated en443
