"A study of dental hygiene as it relates to general health and well-being. Animation illustrates the growth of teeth and their function in chewing, speech and facial contour. Causes of decay, and the general deterioration that follows are demonstrated-particularly the spread of infection following neglect of a diseased tooth. Normal and abnormal conditions are illustrated with models. We learn that preventive care ideally begins at the age of three and continues the regular examinations throughout life. The influence of school dental clinics in checking infection is emphasized."
