Abstract：
This report describes anatomical variations in an indigenous patient from the Brazilian Amazon. A 13-year-old indigenous girl attended the dental clinic for a routine examination. Clinically, a change in the coronary morphology of all upper incisors was observed; characterized by a shovel-shaped lingual surface-a feature considered a polygenic hereditary trait commonly found in native American people. The x-ray examination revealed the presence of a root anomaly in the left upper central incisor. A cone-beam computed tomography (CBCT) scan was performed, revealing the presence of a supernumerary root located on the lingual surface. A single wide canal, which bifurcated in the middle-third level into two canals with different foramina, was observed in the cervical portion. It is essential for dental surgeons to be aware of possible anatomical differences, especially considering the origin of the patient, to avoid interference in treatment success.
摘要：
本报告描述了来自巴西亚马逊的土著患者的解剖学变化。一名13岁的土著女孩到牙科诊所进行例行检查。临床上,观察到所有上切牙的冠状动脉形态发生了变化;特征是铲状的舌面-这一特征被认为是美国原住民中常见的多基因遗传特征。X射线检查显示左上中切牙存在根部异常。进行了锥形束计算机断层扫描（CBCT）扫描，揭示了位于舌表面的多余根的存在。一条宽阔的运河，在中三层分叉成两条不同孔的运河，在子宫颈部分观察到。牙科医生必须意识到可能的解剖学差异，特别是考虑到病人的来源，避免干扰治疗成功。
