This is a curriculum guide for teaching dental health material for grades 7-9. Each topic is outlined under the headings of: (1) reference; (2) major understandings and fundamental concepts; (3) suggested teaching aids and learning activities; and (4) supplementary information for teachers. The topics include: (1) the nature of the problems of dental health; (2) characteristics of oral structures; and (3) the problem of dental carries. The content of this health curriculum guide has been established as a five-strand approach to the concepts, generalizations, understandings, and facts; the values and applications; and the basic skills and decision-making processes that are the keys to good health. The five-strand approach provides maximum flexibility for program development in the schools, and makes it possible to utilize the services of writer-consultants who are experts in their fields.
