Lesions were noted in 7.0 and 4.4% of mandible pairs collected from the Western Arctic caribou herd of northwestern Alaska in 1959-61 and 1975-77, respectively. The prevalence of mandibular lesions in the 1959-61 collection is believed to be the highest reported in wild caribou herds of North America. The frequency of occurrence of mandibular lesions was highest in caribou 7 years of age and older, and there was a higher prevalence in adult males than in adult females. Trauma, dental abscesses, and periodontal disease were the probably cause of most lesions. Pathogenic bacteria were not isolated from mandibular lesions from an 11 year-old female. Thirty-three of 98 (33.7%) mandibles with lesions were missing one tooth, while ten (10.2%) were missing more than one tooth. The first molar (M1) was the most common tooth lost in association with lesions, although the loss of two or more teeth was more common among premolars than among molars.
1959 - 1961年和1975 - 1977年分别从阿拉斯加西北部的西部北极驯鹿群采集的下颌骨对中，发现病变的比例分别为7.0%和4.4%。1959 - 1961年采集样本中下颌骨病变的患病率被认为是北美野生驯鹿群中报告的最高值。下颌骨病变的发生频率在7岁及以上的驯鹿中最高，成年雄性的患病率高于成年雌性。创伤、牙脓肿和牙周病可能是大多数病变的原因。从一只11岁雌性驯鹿的下颌骨病变中未分离出病原菌。98个有病变的下颌骨中有33个（33.7%）缺失一颗牙齿，而10个（10.2%）缺失一颗以上牙齿。第一磨牙（M1）是与病变相关最常缺失的牙齿，不过在乳磨牙中两颗或更多颗牙齿缺失比在磨牙中更常见。
