Mandibles of 2161 juvenile roe deer (8–10 months; 1176 females and 985 males) were studied to check for dental anomalies. The sample was legally shot during the annual harvest (1st January–15th March) of the hunting seasons 2013–2015 in the Arezzo province (Central Italy). The frequency of anomalies was 0.32% (n = 7), confirming that anomalies are uncommon in roe deer dentition. All individuals had only one type of dental anomaly. The teeth of the incisor arcade seldom showed anomalies (10%) in comparison to premolars (20%) and molars (70%). In more than half of juveniles with anomalies, the length of the posterior section of the mandible was shorter than the population average (from − 8 to − 20%), unlike the length of the medio-anterior section. Some dental anomalies seem to affect the growth of the posterior section of the mandible, which occurs mostly during the first year of life, rather than the growth of the medio-anterior section, which occurs mostly in utero. Due to the complex relationship between mandible growth and dental anomalies and their low frequency, further data are needed to deepen the possible influence of anomalies on growth pattern.

研究了 2161 只幼年狍（8-10 个月；1176 只雌性和 985 只雄性）的下颌骨以检查牙齿异常。该样本是在 2013-2015 年狩猎季节的年度收获期间（1 月 1 日至 3 月 15 日）在阿雷佐省（意大利中部）合法拍摄的。异常频率为 0.32% ( n = 7)，证实狍牙列异常不常见。所有个体都只有一种牙齿异常。与前磨牙 (20%) 和磨牙 (70%) 相比，门牙拱廊的牙齿很少出现异常 (10%)。在超过一半的异常幼鱼中，下颌骨后部的长度短于种群平均值（从 - 8 到 - 20%），这与中前部的长度不同。一些牙齿异常似乎影响下颌骨后部的生长，这主要发生在出生后的第一年，而不是主要发生在子宫内的中前部的生长。由于下颌骨生长与牙齿异常之间的关系复杂且频率低，需要进一步的数据来深化异常对生长模式的可能影响。
