Jaws (film) of a shark is simulated, the real shark enters a nearby estuary, killing a boater and causing Brody's oldest son, Michael, to go into shock. Brody then convinces Vaughn to hire Quint. Quint, Brody, and Hooper set out on Quint's boat, the "Orca", to hunt the shark. While Brody lays down a chum line, Quint waits for an opportunity to hook the shark. Without warning, it appears behind the boat. Quint, estimating its length at and weight at 3 tons, harpoons it with a line attached to a flotation barrel, but the shark pulls the barrel underwater and disappears. At
Osteomyelitis of the jaws lower border was involved, and "alveolar", where a segment of alveolar bone down to the level of the inferior alveolar canal would sequestrate, including the sockets of several teeth. Treatment with antibiotics has significantly altered the natural history of OM of the jaws. Today, however, the condition is often a hidden infection, due in part to not being visible on most dental X-rays. In addition, some schools of dentistry do not recognize "silent" OM of the jaws—occurrence of the condition without visually obvious manifestations—in their curriculum. In addition, as circulation is intrinsically diminished in jawbones, antibiotics are frequently ineffective. The
