Kype and/or characteristics that could be of importance in inter- and intra-sexual evaluations of individual quality. The size of the kype is believed to determine male spawning frequency. The extinct sabertooth salmon, "Oncorhynchus rastrosus", was first named for its prominent premaxillary dentition. It possesses an enormous conical tooth on each premaxilla. There is no visible kype on the dentary, implying a different strategy for forming mate dominance. 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
Osteonecrosis of the jaw non-pus forming bone infection osteomyelitis can also be associated with ONJ. However, in patients on bisphosphonates, the cortical bone is frequently involved as well. Spontaneous exposure of necrotic bone tissue through the oral soft tissues or following non-healing bone exposure after routine dental surgery, characteristics of this form of ONJ, may be the result of late diagnosis of a disease process that has been masked by the oversuppression of osteoclastic activity, allowing pre-existing cause to further aggravate bone damage. Osteonecrosis of the jaw Osteonecrosis of the jaw (ONJ) is a severe bone disease (osteonecrosis) that affects the jaws (the maxilla
