Student Learning Outcomes -
  • state the different periods of human embryology
  • describe the differences between enamel and dentin
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 program.
