DES1020 Dental Anatomy

3 credit hour(s) | Fall
Prerequisite(s): Acceptance into the dental assisting or dental hygiene program.
Comprehensive study of the orofacial and related structures of the head and neck. Included is a study of basic tooth structure in the primary and permanent dentition, the formation of those structures, types of teeth, relationship of form to function, principles of occlusion, periodontal health, tooth eruption schedules, and the effects of deviation from normal findings in the permanent dentition. The tissues of the oral cavity and pharynx are discussed, along with salivary glands, bones of the skull and the landmarks of each; muscles of mastication; muscles of facial expression, with origins, insertions, blood supply and innervation of each; distribution of the arteries and veins of the head and neck; lymphatic drainage, and the 12 cranial nerves, with special emphasis on the fifth and seventh. Temporomandibular joint function and disorders causing facial pain will also be discussed. The hands-on portion of DES1020 is designed to provide class exercises which include identification, characteristics, and eruption/exfoliation dates of each of the primary and permanent teeth, distinguishing right from left. Students will use acrylic replicas and natural teeth to locate landmarks and characteristics on each of the primary and permanent teeth. Contact: 3 hours per week. Does not count toward A.A. degree.
