Kype Kype A kype is a hook-like secondary sex characteristic which develops at the distal tip of the lower jaw in some male salmonids prior to the spawning season. The structure usually develops in the weeks prior to, and during, migration to the spawning grounds. In addition to the development of the kype, a large depression forms in the two halves of the premaxilla in the upper jaw, allowing the kype to fit into the premaxilla when the mouth is closed. The kype functions as a secondary sexual characteristic and influences the formation of dominance hierarchies at the spawning grounds. The
Medication-associated osteonecrosis of the jaw turnover, resulting in a higher risk of bone necrosis when repair is needed. Because bisphosphonates are preferentially deposited in bone with high turnover rates, it is possible that the levels of bisphosphonate within the jaw are selectively elevated. To date, there have been no reported cases of bisphosphonate-associated complications within bones outside the craniofacial skeleton. A diagnosis of bisphosphonate-associated osteonecrosis of the jaw relies on three criteria: According to the updated 2009 BRONJ Position Paper published by the American Association of Oral and Maxillofacial Surgeons, both the potency of and the length of exposure to bisphosphonates are linked to the
