The Iberian lynx is an endangered felid that has been subject to an intensive, ongoing conservation program to save it from extinction. Identification of dental pathologies could play an important role in the survival of this endangered species. The prevalence of periodontal bone loss, tooth resorption, and oral neoplasia was evaluated in this species. Skulls of 88 adult specimens of the Iberian lynx ( Lynx pardinus) from the Doñana Biological Station (EBD-CSIC), Seville, Spain, were examined macroscopically and full-mouth dental radiographs of all specimens were performed. Different stages of periodontal disease were identified in 81.3% of teeth. Approximately two-thirds (64.8%) of the specimens examined had at least 1 tooth affected by stage 3 or 4 periodontal disease. Maxillary and mandibular incisor teeth accounted for a majority (59.4%) of teeth affected by stage 3 or 4 periodontal disease. Tooth resorption affected 12 teeth (0.63% of evaluated teeth) in 6 skull specimens (6.8% of skulls evaluated). Five of the teeth with resorptive lesions were detected on 1 skull specimen. Six teeth (50%) of those affected by tooth resorption were incisor teeth. Only 1 (1.1%) adult specimen showed signs of oral neoplasia. Our study concluded that there is a high prevalence of periodontal disease that could lead to impaired hunting ability, as well as may represent a threat to overall health and subsequent survival of this endangered species. The extremely low prevalence of tooth resorption in L pardinus could open new pathways in the discovery on the pathogenesis of tooth resorption in felids.
伊比利亚猞猁是一种濒危猫科动物，一直在接受密集的、持续的保护计划，以使其免于灭绝。牙齿病理学的识别可能对这一濒危物种的生存起到重要作用。对该物种的牙周骨丧失、牙齿吸收和口腔肿瘤的患病率进行了评估。对来自西班牙塞维利亚多尼亚纳生物站（EBD-CSIC）的88个伊比利亚猞猁（Lynx pardinus）成年标本的头骨进行了宏观检查，并对所有标本进行了全口牙齿X光检查。在81.3%的牙齿中发现了不同阶段的牙周疾病。在接受检查的标本中，约三分之二（64.8%）至少有一颗牙齿受到3期或4期牙周疾病的影响。上颌和下颌切牙占受3期或4期牙周疾病影响牙齿的大多数（59.4%）。在6个头骨标本（占评估头骨的6.8%）中，牙齿吸收影响了12颗牙齿（占评估牙齿的0.63%）。在1个头骨标本上检测到5颗有吸收性病变的牙齿。受牙齿吸收影响的牙齿中有6颗（50%）是切牙。只有1个（1.1%）成年标本显示出口腔肿瘤的迹象。我们的研究得出结论，牙周疾病的患病率很高，这可能导致捕猎能力受损，也可能对这一濒危物种的整体健康和后续生存构成威胁。伊比利亚猞猁牙齿吸收的极低患病率可能为猫科动物牙齿吸收发病机制的发现开辟新的途径。
