Dental morphology — the study of the shape and structural features of teeth — is a well-developed subdiscipline of biological anthropology with its own reference database, its own terminological system, and its own tradition of comparative analysis that extends across archaeological periods and geographic regions.

Teeth are among the most reliably preserved elements of the human skeleton and carry an extraordinary amount of information about the individual who carried them.

The deciduous maxillary central incisor is a tooth type with well-documented morphological characteristics in modern and archaeological populations.

Its crown morphology — the specific shapes of the ridges, grooves, and tubercles that characterize the tooth’s surface — varies in patterned ways across human populations, with different population groups showing different frequencies of specific morphological traits.

The detailed description of the Trail Creek tooth’s morphology — published in the dental anthropology literature — characterized its physical features in the standardized terminology used for such analyses.
