Course Description

This course focuses on normal head and neck anatomy and the development and functions of oral anatomy. Topics include dental anatomy, oral histology, oral embryology, osteology of the skull, muscles of mastication and facial expression, temporal mandibular joint, blood lymphatic nerve supply of the head, and salivary glands and related structures.

Course Outcomes

Dental Anatomy




Description

  • Identify the surfaces and anatomical landmarks of teeth.
  • Describe the supporting structures of the teeth.
  • Classify all of the deciduous and permanent teeth according to the universal, palmer notation, and F.D.I. systems and anatomical locations and descriptions and relate this knowledge to clinical application.
  • Identify basic terminology and nomenclature relating to specific morphological characteristics of deciduous and permanent teeth.
  • Identify teeth according to their dentition, arch, and tooth.

  • Identify the layers of alveolar bone.
  • Differentiate between the various periodontal fiber groups and their functions.
  • Describe what causes bone resorption and apposition.

Oral Embryology




Description

  • List the embryonic structures that form the face and discuss the approximate embryonic age of formation.
  • Name the structures that form the palate and the weeks the plate fuses.
  • Name the embryonic structures involved in the development of cleft palate and lip.

  • Describe problems related to the Temporomandibular joint.

Blood Lymphatic and Nerve Supply of the Head




Description

  • Identify and label the blood and nerve supply of the head.
  • Trace the blood supply from the heart to all areas of the oral cavity,                               including the teeth.
