Bone and dental lesions have been documented in various deer species globally, affecting the efficiency of ingestion and digestion, consequently influencing their general health and leading to a decline in survival and reproductive performance. The present study aimed to characterize bone and dental lesions in the dry skulls of individual deer, estimate the prevalence of these lesions, and assess potential risk factors associated with the development of bone and dental alterations. This study assessed bone and dental lesions in 180 dry skulls of eleven neotropical deer species, originating from both captivity and wildlife conditions, through direct visual inspection. A high prevalence of bone and dental lesions was observed in all analyzed species. Dental calculus was the most common alteration (96.7%), followed by dental wear (71.1%). Animal age positively correlated with most bone and dental alterations, indicating that older animals showed more lesions. Additionally, the prevalence of these alterations was similar between sexes. Moreover, all lesions were more common in captive-bred animals, likely attributed to their older age and a less diverse diet. and were most affected by bone resorption and dental trauma and had the highest dental calculus prevalence, along with and . All eleven species evaluated in the present study were susceptible to the occurrence of bone and dental lesions. Therefore, monitoring oral health and diet in captivity are fundamental practices for the conservation of these species.
全球范围内，各种鹿类物种均有骨骼和牙齿病变的记录，这些病变影响摄食和消化效率，进而影响其整体健康状况，并导致生存和繁殖性能下降。本研究旨在描述单个鹿类干颅骨的骨骼和牙齿病变特征，估计这些病变的患病率，并评估与骨骼和牙齿改变发展相关的潜在风险因素。本研究通过直接目视检查，评估了来自圈养和野生环境的11种新热带鹿类的180个干颅骨的骨骼和牙齿病变。在所有分析的物种中均观察到骨骼和牙齿病变的高患病率。牙结石是最常见的改变（96.7%），其次是牙齿磨损（71.1%）。动物年龄与大多数骨骼和牙齿改变呈正相关，表明年龄较大的动物病变更多。此外，这些改变的患病率在两性之间相似。此外，所有病变在圈养繁殖的动物中更为常见，这可能归因于它们年龄较大且饮食种类较少。 以及 受骨吸收和牙齿创伤影响最大，牙结石患病率最高， 和 也是如此。本研究评估的所有11个物种都易发生骨骼和牙齿病变。因此，监测圈养动物的口腔健康和饮食是保护这些物种的基本措施。
