This is a case report of a Caucasian female who presented with an unusual combination of dental anomalies: short roots on the maxillary central incisors and premolars, talon cusps, dentes invaginati, low alveolar bone heights, tubercles of Carabelli on the maxillary first and second permanent molars, with pyramidal root morphology in three of the second permanent molars. None of the anomalies alone are particularly uncommon but they have not previously been reported together. The occurrence of the anomalies is probably incidental as the conditions are aetiologically unrelated.
这是一例白种女性病例报告，该患者出现了不寻常的牙齿异常组合：上颌中切牙和前磨牙牙根短、爪状尖、牙内陷、牙槽骨高度低、上颌第一和第二恒磨牙有卡氏结节，且三颗第二恒磨牙呈锥形牙根形态。这些异常单独出现时都并非特别罕见，但此前尚未有一起报道的情况。这些异常的出现可能是偶然的，因为这些情况在病因上并无关联。
