Dental Anatomy and Physiology
Pre-Test Questions
Course Introduction
Dental Anatomy and Physiology explores the structure, function, and development of the human dentition and its supporting tissues. This course covers the morphology of each tooth, dental nomenclature, and occlusal relationships, as well as the physiological mechanisms underlying tooth eruption, mastication, and oral sensation. Students will gain an understanding of the histology of dental tissues, including enamel, dentin, pulp, cementum, and periodontal ligament, and examine the roles these structures play in oral health and disease prevention. Foundational knowledge from this course provides the basis for clinical practice in dentistry and informs the assessment, diagnosis, and treatment of dental conditions.
