The raison d’&re for this one-volumetext, accordingto the senior author, is the fact that he had to refer to numeroustexts to plan his current pedodonticcurriculum so as to cover the various facets of the discipline. He and his coauthorshave tried to provide a comprehensive,contemporary,and provocative text for students, dental educators,and practitioners. The content of each chapter reflects the knowledge and priorities by an expert in that particular field. There are no fewer than forty-three contributors for the thirty-five chapters.The text is one of the first to include discussionsof psychological growth and developmentand child abusein a comprehensivemanner. Other topics include dental plaque, pathogenesisof dental caries, use of plastic sealants,methods for control of dental plaque, clinical pharmacology, hospital dentistry, care of the handicapped,use of problem-orientedrecords, and staffing and utilization of auxiliaries. Chapters by Enlow and Burdi are especially good, as are chaptersby Rosenstein,Carlos, and Sarles.The orthodonticchaptersby Grewe and Owen are quite appropriateand cover the major concernsthat confront the pediatric dentist. Production details are good; quality of paper, type size, and binding are of high quality. Line drawingsare excellent, but someof the illustrations are “washed out” in the conversionprocessfrom color slides. Nevertheless,the book is an excellent state-of-theart volume for any dentist interestedin children’s dentistry. T. M. Graber
Growth
Rate of the Condylar
Cartilage of the Mandible

Both nocturnal and diurnal (nyctochemeral)and seasonalvariations occur in the growth rate of the mandibularcondylar cartilage in young rats. The greatestactivity, as exemplified by the maximum number of tritiated thymadine-labeledcells, occurs in the middle of the rest or sleepingperiod (13 hours), and the month of greatestactivity is May. Since rats sleepduring the day and humanbeings at night, a comparabletime for humans would be 1 A.M. The responsivenessof the condylar cartilage to orthopedic appliances(for example, posturalhyperpropulsoror active retropulsorof the mandible) is greatestwhen the spontaneousgrowth rate of the condylar cartilage is greatest. The bone formation also exhibits nyctochemeraland seasonalvariations. It reachesa maximum around 19 hours (extrapolatingto human beings, perhaps7 A.M.) and also in the month of May. The bone mineralizationexhibits only seasonalvariations; the uptake of radioactive calcium is greaterin May than in November.
