Attrition and the edge-to-edge bite. An anthropological study

|April 1, 1983
Summary
This study examined tooth overjet and attrition in ancient Californian skulls. Researchers found a significant negative correlation between these two dental traits.
Area of Science:
- Paleoanthropology
- Bioarchaeology
- Dental Anthropology
Background:
- Understanding dental morphology and wear patterns in past populations provides insights into diet and lifestyle.
- Previous research has explored various dental metrics, but the relationship between overjet and attrition requires further investigation.
Observation:
- The study analyzed overjet (the horizontal overlap of the incisal edges of the lower anterior teeth by the upper anterior teeth) and tooth attrition (the wearing down of teeth) in skeletal remains.
- The sample comprised skulls from aboriginal California populations, offering a specific regional and cultural context.
Findings:
- A strong negative correlation was identified between overjet and tooth attrition.
- This suggests that individuals with greater overjet experienced less tooth wear, and vice versa.
Implications:
- The findings may indicate differences in dietary consistency or the use of teeth as tools among aboriginal Californians.
- Further research could explore the biomechanical factors influencing this observed relationship.
- This study contributes to the broader understanding of human adaptation and oral health in prehistoric populations.
