The third edition of this popular, easy-to-read text is updated and revised throughout. Designed and written to meet the needs of shorter dental assisting programs or those looking for a quick resource, this practical text helps students easily grasp the information essential for practice. Tables, boxes and step-by-step procedures highlight key content. New student learning aids include highlighted key terms, chapter goals, and Apply Your Knowledge questions at the end of each chapter. It is also a valuable reference tool for on-the-job training for staff who are taking continuing education courses and studying for state and national boards.
