The first unit is an introduction to dental assisting and contains five topics of study. The second unit covers nine anatomy and physiology topics, and the third unit consists of seventeen topics dealing with laboratory procedures. Each unit includes an introduction, objectives, equipment needed, and a written laboratory exercise which may be assigned for the student's own personal use, for classroom discussion, or as homework. Many of the units contain final criteria sheets for instructor evaluation.
