Oral Biology Exam Practice Tests
Course Introduction
Oral Biology is a foundational course that explores the structure, function, and development of the oral and craniofacial complex at the molecular, cellular, and tissue levels. It covers key topics such as tooth development, oral mucosa, bone biology, salivary glands, and the biological processes underlying oral diseases. The course also examines microbial ecology of the oral cavity, mechanisms of host defense, and the interplay between genetics and environmental factors in oral health. Emphasis is placed on the relevance of oral biology to clinical dentistry, providing students with the scientific framework necessary for understanding normal oral function as well as the pathogenesis of oral diseases.
