Written specifically for dental hygienists, this textbook provides an overview of public health beyond the traditional view of community dental hygiene and offers a thorough presentation of the roles and responsibilities of the dental hygienist in public health. The competencies covered are based on the American dental Education Association Competencies for Entry into the Profession of Dental Hygiene, and provide guiding principles to assure that students are prepared for the National Board Exam and dental hygiene practice.
