A number of significant pressures are creating tensions in the dental profession and the dental care delivery system. These pressures may be categorized in five major areas: 1) regulation and deregulation pressures involve changes in the state dental practice acts, court decisions concerning antitrust and advertising, and the inclusion of consumers on State professional regulatory boards; 2) cost of services includes factors involving the out-of-pocket cost of dental care and the growth of dental insurance; 3) dentist-related factors include the increased number of dentists and the indebtedness of dental graduates; 4) the pressures of changes in the American populations include the decline in population growth and the increase in proportion of elderly people; 5) changes in the distribution of dental care are based on new epidemiologic data concerning dental caries and progress in the prevention of periodontal disease. Many of these pressures are inducing competition in the dental care system. It is clear that the dental care system is in the process of change as it responds to these complex pressures.
