The fragmentary early Late Pleistocene, early modern human remains from Zhirendong, south China, present a suite of dentoalveolar pathologies and anomalies. The lesions include lower molar buccal alveolar resorption (Zhiren 1), massive dental caries in a mandibular molar associated with hypercementosis (Zhiren 2), and bilateral mesial premolar (P) periapical lesions (granulomata with a probable left abscess) (Zhiren 3). The Zhiren 3 periapical lesions, given their bilaterality and the non-pathological incisor and canine alveoli, suggest dens evaginatus, although absence of the Zhiren 3 dentition prevents full evaluation of this diagnosis. These periodontal abnormalities join a number of similar lesions in Pleistocene humans, of varying severity. The carious lesion is noteworthy, given the rarity of them in the Pleistocene human fossil record. In addition, Zhiren 3 exhibits unilateral P rotation and bilateral I rotation (winging).
中国南方智人洞发现的更新世晚期早期的人类遗骸支离破碎，呈现出一系列牙槽病变和异常。这些病变包括下臼齿颊侧牙槽骨吸收（智人1号）、一颗下颌臼齿上伴有牙骨质增生的大量龋齿（智人2号），以及双侧前磨牙（P）根尖病变（肉芽肿，左侧可能有脓肿）（智人3号）。智人3号的根尖病变，鉴于其双侧性以及无病变的切牙和尖牙牙槽，提示为畸形中央尖，尽管智人3号没有完整牙列，无法对这一诊断进行全面评估。这些牙周异常与更新世人类中一系列不同严重程度的类似病变并存。鉴于龋齿病变在更新世人类化石记录中较为罕见，所以值得关注。此外，智人3号还表现出单侧P旋转和双侧I旋转（翼状）。
