COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Integrate an understanding of development, structures, systems, and anatomy of the head and neck into clinical dental hygiene practice.

2.  Differentiate between the normal and abnormal/pathologic when conducting a physical examination of the patient's head and neck structures.

 

Objectives:

Students will be able to:

1. Describe the process of embryologic and prenatal development of the orofacial structures and the clinical considerations due to developmental disturbances within these periods.

2. Discuss the stages of tooth development including eruption and exfoliation patterns and the clinical considerations due to developmental disturbances.

3. Discuss the histological features of basic tissues; epithelium, connective tissue, nerve tissue, and muscle tissue.

4. Discuss the histological features, development, and properties of the enamel, dentin, pulp, cementum, alveolar process, and  periodontal ligament.

5. Identify the types of oral mucosa, discuss the regional differences, and integrate this knowledge into patient care.

6. Identify and describe the skeletal, lymphatic, vascular, nervous, and the muscular systems associated with the head and neck region.

7. Identify and describe the function of the glands associated with the head and neck.

8. Describe the anatomy, movements and associated muscles and ligaments of the temporomandibular joint.

9. Accurately identify and use the anatomical landmarks needed for successful local anesthesia.

10. Apply knowledge of head and neck structures to extraoral and intraoral examination in clinical hygiene courses.

11. Differentiate between normal and abnormal/pathological findings on dental radiographs.

Methods of Evaluation/Basis of Grade.

Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing.		Writing 0 - 0%
None
This is a degree applicable course but assessment tools based on writing are not included because problem solving assessments and skill demonstrations are more appropriate for this course.
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills.		Problem Solving 10 - 20%
Local anesthesia - identification of landmarks and evaluation of clinical considerations
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 25 - 35%
Lab exercises: drawings, models, skulls
Exams: All forms of formal testing, other than skill performance exams.		Exams 50 - 60%
Quizzes and exams
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 0 - 0%
None
