Heretofore unreported, grossly observable structures composed of cementum were found in the superficial alveolar bone--but not attached to the tooth root--in three prehistoric American Indian skeletons from South Dakota. The macroscopic, radiographic, and histologic morphology of these fragments is described and compared with other cemental structures that occur in the alveolar process.
此前未被报道过的、由牙骨质构成的肉眼可见结构，在来自南达科他州的三具史前美洲印第安人骨骼的浅表牙槽骨中被发现——但未附着于牙根。本文描述了这些碎片的宏观、放射影像学和组织学形态，并与牙槽突中出现的其他牙骨质结构进行了比较。
