fluids to the underlying structures and contributed to the loss of this tooth, which had a carious exposure. Several statements relative to mixed dentition treatment-for example, that anterior cross-bite is the only malocclusion to be treated in the mixed dentition and that crowded mandibular incisors frequently are a developmental, and hence a harmless, phenomenon-are contrary to American orthodontic findings. The second part of this text contains much practical information on the provision of community dental health. Methods of appraising of community dental needs, demands, and methods of providing the service are discussed. This book should prove of interest to public health personnel and dentists interested in children’s dental needs. J. A. SaZznta.n~z

Although this book has fourteen contributors, thirteen of the twenty-eight chapters are by Ralph E. McDonald, who is a recognized authority in pedodontics. It is surprising, therefore, to find, on page 13, Fig. l-12A, that McDonald advocates excision of the frenum to correct a central incisor diastema in the deciduous dentition. The chapter on examination of the mouth is combined with treatment of anomalies of the teeth and soft tissues. Much useful information is contained in the chapter on behavior guidance of the child in the dental office. The basic principle is t,o impress the child, with a friendly attitude, of the importance of the dental procedures and to explain the office equipment as well as the dental work to be accomplished. It is important to lea.ve the impression with the child that there is no desire to force the issue. The dentist,, we are told, should remember that he and his assistant constitute the real threat as the child views the situation. Short appointments are advocated until the child’s apprehension is dissipated. “A child who is lacking in discipline at home,” we are told, “many times will respect the dentist who supplies it.” In the end, the child must realize that he cannot always have his own way. Chapters are provided on t,he normal and pathologic development of the teeth and jaws, tooth eruption, radiographic technique for children, and the clinical mnnagcnicnt of dental caries. Indications and contraindications for premeditation are explained. An informative chapter by It. W. Phillips deals with dental materials in pedodontics. Periodontal diseases in children, usually glossed over in texts, is here given detailed discussion, as are toothbrushing and general dental hygiene. Space maintenance is treated in some det,ail. One wonders when pedodontists will eliminate the use of submucosal spurs which the originator of this type of space maintainer, the late R. C. Willett, confessed to this reviewer he was sorry he ever introduced since there is danger of infection.

McDonald has included a valuable chapter on the diagnosis and correction of minor irregularities in the developing dentition. Tht: most import.ant, advice given by James E. Roche, who contributes the chapter on praeticc management, is that., beginning with the receptionist on through the office auxiliary personnel and up to the doctor, the primary impression that should be left with the parent and patient is that all are not only entirely concerned with the patient’s welfare and comfort but are anxious to be of service and that no one else is of equal importance to them. Appointments for children should be scheduled in a sequential manner, one at a time. The chapter on community health is interesting but omits any reference to the clinical and prepayment aspects. J.

The United States has one of the most favorable persons-per-dentist ratios in the world-about 1,801) persons per dentist. Over the years, the American system of dental education has produced an increasing number of better-trained and more productive dentists. Similar gains have been made in the last few years in the number of accredited training programs for dental hygienists, dental assistants, and dental laboratory technicians. Yet the dental profession is confronted with a critical shortage of manpower that threatens to impair its ability to meet future demands for dental services. Present dental resources are not sufficient to meet a greatly increased demand for dental care, according to estimates and projections of the dentist supply prepared by the Division of Dental Health, Public Health Service. In mid-1967, there were approximately 112,150 dentists in the United Sta.tes (excluding 1967 graduates). This total includes an estimated 90,715 active nonfederal dentists located in the fifty states and the District of Columbia; about 7,955 federal dentists in the Armed Forces, Public Health Service, and Veterans Administration; and 13,480 dentists who are retired or engaged in nondental activities. Although there have been sizable gains in the number of dentists in recent years, the dentist-to-population ratio in 1967 stood at 46 active nonfederal dentists per 100,000 civilian population, as compared with 50 dentists per 100,000 civilians in 1950. The availability of dental services varies widely throughout the nation because of the uneven geographic distribution of dentists in relation to population. It is estimated that, of the 98,670 active dentists (federal and nonfederal) in 1967, some 80,000 will still be active in the dental profession in 1975, allowing for both deaths and retirements. It is further estimated that by 1975 about 29,000 new graduates will be added to the dental force. Therefore, only about 109,000 active dentists may be expected to be available in 1975. Assuming that expenditures for dental care will continue to increase at the post-World War
