Dental anatomy. Historical anatomical artwork of healthy and diseased human teeth and jaws. The teeth and jaws are seen from several different directions. At upper right is an adult's upper jaw, seen from below. At lower right is an adult's lower jaw, seen from above. At centre left are an adult's jaws seen from the side, dissected to show the roots of the teeth. At lower left are two views of a child's jaws showing the milk teeth and buds of adult teeth. The artworks of individual teeth are mostly diseased or deformed, like the molars at upper centre with fused or divergent roots. Artwork from Atlas of Anatomy, by Bourgery and Jacob, published in France in 8 volumes from 1831 to 1854.
