$360.99

The left mandible of a postadolescent with its full complement of eight teeth, approximately three times life size, is faithfully rendered in unbreakable plastic. The bony outer layer of the jaw is cut away, exposing the mandibular blood vessels, roots of the teeth, and their nerves. Sectioned longitudinally from crown to root, one molar shows the destructive action of caries, while another exhibits advanced inflammation (pulpitis). The inner surface of the jaw shows the submaxillary and sublingual salivary glands.

48 numbered features are defined in the accompanying key.

Overall dimensions: 13×14×9 inches (33×36×23 cm).
