DHYG 314 Biological Structures III: Embryology and Histology (2 credits)
Prerequisite Current enrollment in Bachelor of Applied Science in Dental Hygiene program.
Course Description
This is the third in a series of three courses. Content continues a comprehensive study of structures and functions of the human head and neck region and oral structures. These fundamentals are the building blocks for understanding the elements of healthy oral tissues and related pathology. An understanding of embryology is a key to understanding the etiology of many common congenital defects affecting the head, neck, face, oral structures, and/or the teeth.
Course Content
1. Dental and biological terminology relevant to embryology and histology
2. Embryology of head and neck structures
3. Histology of head and neck structures, and the dentitions
4. Morphology of the dentitions
5. Embryological and histological timeline of the development of head and neck structures
6. Biological basis of diseases and adverse conditions in the head and neck
Student Outcomes
These outcomes are specific and relevant to the theory and practice of dental hygiene. The student should be able to integrate essential developmental facts and concepts of orofacial structures into clinical observation and assessment of these structures. Other courses building on this foundation include: Fundamentals of Dental Hygiene, Oral Pathology, Periodontology, and Restorative Dentistry. In all class and lab settings, accurately and consistently:
1. Demonstrate correct and accurate usage of terminology associated with course content
2. Identify the cells and basic tissue components of structures of the head and neck and dentitions
3. Demonstrate accurate and detailed understanding of the basic tissue components of the head, neck, face and oral cavity, and the dentitions
4. Demonstrate an accurate and detailed understanding of the: a. embryonic development of the hard and soft tissues and systems of the head, neck, face and oral cavity, and the dentitions b. histology of the hard and soft tissues and systems of the head, neck, face and oral cavity, and the dentitions c. anatomical and physiological basis for form and function of the hard and soft tissues and systems of the head, neck, face and oral cavity d. morphology of the crowns and roots of primary and permanent human teeth e. embryological and histological timeline of the development of head and neck structures
Degree Outcomes
This course is part of the Associates in Dental Hygiene Degree. Please refer to the Dental Hygiene Competency Map for detail of the Program Competencies this course addresses.
