Oral Biology Exam Bank
Course Introduction
Oral Biology is a foundational course that explores the structure, function, and development of the oral and maxillofacial regions at the cellular and molecular levels. It covers topics such as the biology of teeth, oral mucosa, bone, salivary glands, and the temporomandibular joint, as well as the mechanisms of oral microbial ecology, host responses, and tissue regeneration. The course also examines the biochemical pathways relevant to oral health and disease, providing students with a comprehensive understanding essential for clinical practice and further research in dentistry.
