Skulls from 277 California bobcats (Lynx rufus californicus) were examined macroscopically and by radiography. The majority of the skulls were from adult animals (79.8%). The skulls were from 128 male (46.2%) and 114 female (41.2%) animals and gender was unknown for the remainder. The majority (95.6%) of teeth were present for examination. Only 16 teeth were identified as absent congenitally and 15 of these were incisor teeth. Teeth with abnormal morphology were rare (0.5%). The two most common abnormalities were unusually large crowns of the maxillary first molar teeth and bigemination of the mandibular incisor teeth. Teeth with an abnormal number of roots were uncommon (n = 68). Sixty-three teeth had abnormal roots, mostly the presence of two roots instead of one for the maxillary first molar tooth. The most prevalent dental lesions found in the California bobcat were attrition/abrasion (85.2%), periodontitis (56.0%) and tooth fractures (50.9%). Less common dental lesions were endodontal disease (n = 114 teeth) and tooth resorption (n = 73 teeth).
对277只加利福尼亚山猫(猞猁属加州亚种)的头骨进行了宏观检查和X光检查。大多数头骨来自成年动物(79.8%)。这些头骨来自128只雄性动物(46.2%)和114只雌性动物(41.2%),其余动物的性别未知。大部分(95.6%)牙齿可供检查。仅16颗牙齿被确定为先天性缺失,其中15颗为门牙。形态异常的牙齿很少见(0.5%)。两种最常见的异常情况是上颌第一磨牙牙冠异常大以及下颌门牙双生。牙根数量异常的牙齿不常见(n = 68)。63颗牙齿有异常牙根,主要是上颌第一磨牙有两根而非一根。在加利福尼亚山猫中发现的最常见牙齿病变是磨损/磨耗(85.2%)、牙周炎(56.0%)和牙齿骨折(50.9%)。较不常见的牙齿病变是牙髓疾病(n = 114颗牙齿)和牙齿吸收(n = 73颗牙齿)。
