[Proximal grooves in Danish mesolythic and neolythic molars]
Deutsche Zahnarztliche Zeitschrift
|March 1, 1978
Summary
Mesolithic and Neolithic teeth from Denmark exhibit approximal grooves, potentially from therapeutic bone clasps. These findings correlate with tooth wear, bone loss, and caries in ancient populations.
Area of Science:
- Paleodontology
- Bioarchaeology
- Dental Anthropology
Context:
- Analysis of 350 Mesolithic and Neolithic human dentitions from Denmark.
- Identification of approximal grooves on teeth dating back to prehistoric eras.
Purpose:
- To investigate the occurrence and characteristics of approximal grooves in ancient human teeth.
- To explore potential etiological factors and functional implications of these grooves.
Summary:
- Approximal grooves were observed in 24 out of 350 ancient Danish teeth, specifically on molars, premolars, and a canine.
- These horizontally oriented grooves were located in the root dentine, extending slightly onto the cervical enamel, and exhibited a polished, well-demarcated appearance.
- The grooves were associated with significant tooth wear (75%), marginal bone loss (70%), and caries (30%), suggesting a potential link to therapeutic or palliative interventions using bone implements.
Impact:
- Provides insights into ancient dental health practices and potential therapeutic interventions.
- Contributes to understanding the relationship between oral hygiene, tooth wear, and disease in prehistoric populations.
- Highlights the value of dental wear patterns as indicators of past human behavior and health status.
