DHYG 106 Oral Anatomy and Tooth Morphology

This course examines the development of the head and neck as it applies to the practice of dental hygiene. Emphasis will be placed on the surface and underlying structures of the head and neck, concentrating on the muscles, nerves, blood supply, lymphatic drainage, cranial, and facial bones and their relationship to the teeth. Dental hygiene students will focus on the maxilla and the mandible. Also included will be the structure, morphology, eruption, and functions of the primary and permanent dentitions.

Course Objectives

1. 1. Locate and identify the regions and associated surface landmarks of the head and neck on
   a diagram and a patient.
2. 2. Locate and identify the bones of the head and neck and their landmarks on a diagram,
   skull, and patient, and describe in detail portions and landmarks of the maxilla and
   mandible.
3. 3. Locate and identify the muscles of the head and neck on a diagram, skull, and patient,
   and describe the origin, insertion, and action of each muscle of the head and neck.
4. 4. Discuss the process of mastication, speech, and swallowing with regard to anatomical
   considerations.
5. 5. Locate and identify the specific anatomical landmarks, describe movements and
   relationship with head and neck muscles, of the temporomadibular (TMJ) joint on a
   diagram, skull, and patient. Describe the disorders of the TMJ.
6. 6. Identify and trace the routes of blood vessels and nerves of the head and neck on a
   diagram, skull, and patient.
7. 7. Locate and identify all the glandular tissue and associated structures in the head and neck
   region on a diagram, skull, and patient.
8. 8. Briefly discuss the general function and location of each cranial nerve and structures
   associated with local anesthesia.
9. 9. Identify and trace the routes of the nerves to the oral cavity and associated structures of
   the head and neck on a diagram, skull, and patient.
10. 10. List and locate the lymphatic system and its components of the head and neck on a
    diagram and extra-orally on a patient.
11. 11. Describe and lymphadenopathy of lymphoid tissue, cancer of the head and neck region.
12. 12. Discuss the spread of dental infections/trace the routes on a diagram, skull, and patient.
13. 13. Describe anatomical features of anterior and posterior teeth (primary and permanent
    dentitions).
14. 14. Categorize anterior and posterior teeth as incisors, pre-molars, or molars (primary and
    permanent dentitions).
15. 15. Categorize anterior and posterior teeth using the Universal Numbering System (primary
    and permanent dentitions).
