Student Learning Outcomes -
  • The student must be able to identify tooth abnormalities caused by an interruption in the tooth development process.
  • The student will assess and identify a patient's caries risk and propose a plan to either arrest the patient's caries process or reduce further risk of decay.
Description -
An overview of 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. Developmental and structural defects involving the oral cavity and the teeth. Periodontal diseases, caries process and oral pathology. Intended for students in the dental assisting program.

Course Objectives -
The student will be able to:
Dental Assisting Theory & Practice
  1. identify the stages of embryologic and fetal development of the head and oral cavity.
  2. from a list of the tissues of the head and oral cavity, associate each with the germ layer from which it arises.
  3. identify anomalies of the oral structures with failures of development of specific embryologic structures.
  4. describe the appearance of/or recognize, specific types of facial and oral developmental anomalites.
  5. list and describe common developmental defects involving the teeth.
  6. list in order, the stages of tooth development and describe the characteristic activities of each stage.
  7. describe general pathology terms.
  8. describe different types of pathology found in the oral cavity.
  9. list and describe the tools available to identify the presence or absence of oral pathology and the information obtained by the use of each.
  10. describe the caries process.
  11. describe the AAP types of periodontal diseases and how periodontal disease develops.
  12. briefly describe and define the process of inflammation, regeneration, repair and healing.
  13. list the most common dental infections and describe their course, treatment, and resolution.
