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 known to occur spontaneously. There may be no symptoms for weeks or months, until lesions with exposed bone appear. Lesions are more common on the mandible than the maxilla. Post radiation maxillary bone osteonecrosis is something that is found more in the lower jaw (mandible) rather than the maxilla (upper jaw) this is because there are many more blood vessels in the lower jaw. The symptoms of this are very similar to the symptoms of MRONJ. Patients are in a lot of pain, the area may swell up, bone may be seen and fractures may take place. The patients may
