The two first are smaller than the rest, terminating in two points, and therefore styled by J. Hunter bicuspides. They have short fangs, which are double at their extremities. The other three on each side have four points at the basis of their bodies, two anteriorly, and two posteriorly; these have generally two fangs in the lower jaw, and three in the upper. Mr. John Hunter observes, that the first and second of the grinders are nearly alike: they stand next behind the canini or eye teeth; and the first is frequently the smallest, with rather the longest fang, sometimes with its point bent. In the upper jaw, the bicuspides are rather thicker than in the lower; and both, especially the second in both jaws, are oftener wanting than any others, except the denies sapientiae. The bicuspides and the molares alter very little in shape on their grinding surfaces, by use; their points only wear and become obtuse. The two first grinders differ from the bicuspides in being much longer, and in having more points and more fangs. The body forms almost a square, with rounded angles. The grinding surface has commonly five protuberances, two of which arc on the inner, and three on the outer edge or part of the tooth, with generally some smaller points at the roots of these Longer protuberances. The body towards its neck divides into two flat fangs, one forward, the other backward, which are often bifurcated.. The first grinder is somewhat larger and stronger than the second; and both have shorter fangs than the bicuspides. In the upper jaw they have three fangs; and the first and second in the upper jaw are placed directly under the maxillary sinus. The third grinder is the dens sa-fiientia. See Dens. J. Hunter's Natural History of the Human Teeth.
Molares Glandulae, are two glands, nearly of the same 'kind with the sublingual glands, each of them situated between the masseter and buccinator muscle, resembling, in some subjects, two small lumps of fat. They send out small ducts, which perforating the buccinator, open into the cavity of the mouth, almost opposite to the last denies molares; from which circumstance, Heister gave them their name.
