Module: Morphology Learning Objectives 1. Define the Key Terms. 2. List the name and location of the primary and permanent teeth. 3. Identify the surfaces of each tooth. 4. List the anatomical structures of the teeth and their definitions. 5. Recognize the dental arches and quadrants. Copyright © 2006 Thomson Delmar Learning. ALL RIGHTS RESERVED. 3
