In this lecture, Professor Zach Murphy will guide you through the detailed anatomy of the teeth using an anatomical model. We begin by reviewing the primary divisions of the human dentition, distinguishing between the incisors, canines, premolars, and molars, and identifying their positions within the maxilla and mandible. We then examine the structural components of each tooth, including the crown, neck, and root, while highlighting the roles of enamel, dentin, pulp cavity, cementum, and the periodontal ligament. The lecture continues with a discussion of tooth numbering systems, including the universal numbering method, and how these are used in both dental and medical practice. We also explore the differences between primary (deciduous) and permanent teeth, focusing on developmental timelines and functional adaptations for cutting, tearing, and grinding food. Special attention is given to the relationships between teeth, surrounding alveolar bone, and the gingiva, as well as the vascular and nerve supply from the maxillary and mandibular branches of the trigeminal nerve.
