Skulls (n = 301) of adult feral cats from Marion Island were examined macroscopically. Dental calculus was found infrequently (9.0% of cats, 0.76% of teeth), unlike the hard tissue lesions of moderate and advanced periodontitis and tooth loss (presumably due to periodontitis), which were commonly seen (61.8% of cats, 14.8% of teeth). Relatively few of these abnormalities were associated with external odontoclastic resorption lesions, which affected 14.3% of cats and 1.2% of teeth-less than in most recent surveys in domestic cats. Abnormal thickening of the mandibula, found in 39.5% of specimens, was most commonly bilateral (83.3%). The lesions ranged from a focal periosteal reaction, to localized exostosis, to generalized swelling and loss of density, to grossly enlarged mandibles with increased bone density. Mandibular swelling was significantly associated with other abnormalities (periodontitis, dental fractures, external odontoclastic resorption lesions and periapical lesions), but many cases of mandibular swelling were accompanied by only minor dental defects.
对来自马里恩岛的301只成年野生猫的头骨进行了宏观检查。牙结石较少见（占猫的9.0%，占牙齿的0.76%），而中度和重度牙周炎及牙齿脱落（可能由牙周炎引起）的硬组织病变则很常见（占猫的61.8%，占牙齿的14.8%）。这些异常中相对较少与外部破牙骨质吸收病变有关，该病变影响了14.3%的猫和1.2%的牙齿，比最近对家猫的大多数调查结果要少。在39.5%的标本中发现下颌骨异常增厚，最常见的是双侧增厚（83.3%）。病变范围从局灶性骨膜反应到局部骨赘形成，再到广泛性肿胀和密度降低，直至下颌骨明显增大且骨密度增加。下颌肿胀与其他异常（牙周炎、牙齿骨折、外部破牙骨质吸收病变和根尖病变）显著相关，但许多下颌肿胀病例仅伴有轻微的牙齿缺陷。
