Extensive caries in early man circa 110,000 years before present

|October 1, 1979
Summary
Rhodesian man experienced severe tooth decay despite adaptive attrition, suggesting dietary changes and elemental deficiencies contributed to high caries susceptibility. His central incisors showed remarkable resistance to this dental disease.
Area of Science:
- Paleoanthropology
- Paleopathology
- Dental Anthropology
Background:
- Examining the dental health of ancient hominins provides insights into past lifestyles and environmental factors.
- Rhodesian man, an ancient hominin, presents a unique case study for understanding prehistoric dental pathologies.
Observation:
- The 35-year-old Rhodesian man exhibited severe dental caries (tooth decay) but also physiologically adaptive attrition and periodontal health.
- Hypoplasia, a developmental defect, was not observed in his dentition.
- Caries were extensive, occurring without modern cariogenic factors like specific bacterial strains or refined carbohydrates.
Findings:
- The severe caries suggest a high susceptibility, potentially linked to a deficiency in the elemental composition of his diet.
- A notable observation was the resistance of his central incisors to caries, indicating localized protective factors.
- The progression of dental disease may have influenced dietary shifts and the development of food processing techniques.
Implications:
- This case highlights the complex interplay between diet, elemental composition, oral microbiome, and dental health in ancient populations.
- Understanding prehistoric dental disease can inform current public health strategies and our knowledge of human evolution.
- The resistant central incisors may offer clues for future research into natural caries resistance mechanisms.
