The use of swine in dental and oral surgical research was relatively uncommon in the past, probably due to the anatomy of the head, neck, and oral cavity. However, there has been increased activity in porcine models involving dental research and there are >300 literature citations since 2000. The skull in Figures 1-2 is from an immature domsetic pig and the one in Figures 3-4 is from a sexually mature wild boar. Much of the older literature is related to descriptions of the anatomy and pathophysiology and the newer literature is more related to development of actual models.
