Student Learning Outcomes

  • The student will be able to trace the origin of mature oral tissues back to the trilaminar disc.
  • The student will be able to list the origin and formation of enamel.

Description

The embryologic development of the structures and tissues of the head, neck, teeth and oral cavity; histology of the hard and soft tissues of the oral cavity. Anatomy of the tooth crown, root and pulp; development and structural defects involving the oral cavity and the teeth. The normal periodontal tissues, oral mucous membranes, and salivary glands. Intended for students in the Dental Hygiene Baccalaureate Degree Program; enrollment is limited to students accepted in the program.

Course Objectives

The student will be able to:
A. Illustrate and describe a cell and its components.
B. Categorize the components and function of the four basic tissues of the body.
C. Classify the developmental stages of the human from fertilization to birth.
D. Discuss the mechanism involved in the development of the face and oral cavity.
E. Describe the types of facial and oral developmental anomalies.
F. Explain the stages of tooth development, and describe the characteristic activities of each stage.
G. Identify and compare the dental tissues under a microscope.
H. Identify and compare the histologic components of the periodontium and oral mucous membranes.
