Non-carious interproximal grooves in Arikara Indian dentitions
American Journal of Physical Anthropology
|February 1, 1979
Summary
Noncarious interproximal grooves were found in 30% of Arikara Indians from the Larson site. Dental probes and grit in the diet are the likely causes of these grooves.
Area of Science:
- Paleoanthropology
- Bioarchaeology
- Dental Anthropology
Background:
- Examining Arikara Indian dentitions from the Larson site (39WW2).
- Investigating the prevalence and causes of noncarious interproximal grooves.
Observation:
- Groove morphology, location, and association with dental pathology were documented.
- Approximately 30% of individuals displayed pronounced interproximal grooves.
Findings:
- The study identified noncarious interproximal grooves in a significant portion of the Arikara sample.
- Evidence suggests dental probes and abrasive dietary components contributed to groove formation.
Implications:
- Understanding habitual behaviors and environmental factors influencing dental health in past populations.
- Provides insights into the oral health practices and lifestyle of the Arikara people.
