Prerequisite(s): With a C or higher: REA 091  or higher, or Reading Assessment into REA 112 .
Corequisite(s): DLT 101LB  
Information: Consent of program director is required before enrolling in this course.

Course Learning Outcomes
  1. Identify the roles and responsibilities of various members of the dental health care team.
  2. Locate, describe, and duplicate various elements of dental morphology.
  3. Identify permanent and deciduous teeth using common tooth numbering systems.
  4. Articulate dental casts using various dental articulators.
  5. Safely operate and maintain dental laboratory equipment.

Performance Objectives:
  1. Identify and explain ethics, legal aspects, jurisprudence, the history, and organization of the dental health team and dental practice.
  2. Locate, identify, and describe anatomical landmarks of the teeth and oral cavity.
  3. Identify and explain basic terminology.
  4. Locate, identify, and describe basic anatomical landmarks of the teeth, permanent dentition, and deciduous (primary) dentition.
  5. Detail the location and function of head and neck skeletal structures and musculature.
  6. Enumerate oral structures and related physiology.
  7. Sculpt a full set (1 x 32) of maxillary and mandibular teeth in soap, wax, or gypsum.
  8. Mount stone models on various types of dental articulators.
  9. Identify various types of dental articulators and detail their relative advantages and disadvantages.
  10. Locate, identify, and describe occlusal relationships (centric, protrusive, working, and balancing) and their characteristic marking on articulated models using various articulating papers.
  11. Perform maintenance and safely operate laboratory equipment and tools.
