ASUDAS
Definition
Arizona State University Dental Anthropology System: a standardised plaque-based scoring system for 29 dental morphological traits developed by Christy Turner II and colleagues. Scores run from 0 (absent) to 5, 6, or 7 depending on the trait, defined by physical reference plaques (and later digital versions) to ensure inter-analyst consistency.
