Relationships between attrition and lingual tilting in human teeth

|June 1, 1983
Summary
Severe tooth wear, or occlusal dental attrition, is linked to lingual tilting of teeth. This dental change is more common with pronounced attrition, potentially driven by masticatory stress.
Area of Science:
- Paleoanthropology
- Dental Anthropology
- Bioarchaeology
Background:
- Investigated associations between occlusal dental attrition and lingual tilting of human teeth in aboriginal California populations.
- Literature review suggests lingual tilting correlates geographically and temporally with the helicoidal occlusal plane, implying its presence in the Homo osteological record.
Observation:
- Examined attributes of lingually tilted teeth, including buccal alveolar abscesses, exposed pulp chambers, extent of tooth attrition, angle of lingual tilt, and overjet.
- Analyzed these attributes statistically to understand their relationship with lingual tilting.
Findings:
- Lingual tilting of teeth is generally slight and infrequent.
- Pronounced occlusal dental attrition significantly increases the likelihood and degree of lingual tilting.
Implications:
- Suggests masticatory stress as a contributing factor to lingual tilting.
- Proposes a feedback model where severe attrition syndrome, initiated by heavy occlusal tooth wear, may manifest as lingual tilting.
- Highlights the need to explore age-related changes, the helicoidal occlusal plane, and masticatory forces in future research.
