Oral Biology
Midterm Exam
Course Introduction
Oral Biology is the scientific study of the structure, function, development, and pathology of the oral and maxillofacial region. This course explores the biology of oral tissues, including enamel, dentin, cementum, pulp, periodontal ligament, oral mucosa, and salivary glands. Students learn about the molecular, cellular, and physiological processes that govern oral health and disease, as well as microbial interactions within the oral cavity. Emphasis is placed on the relationship between oral biology and clinical dental practice, providing an essential foundation for understanding preventive, diagnostic, and therapeutic approaches in dentistry.
