Degenerative Methods
Definition
Methods that estimate age from accumulated wear and structural change in adult teeth: attrition, pulp recession, cementum deposition, secondary dentine, and chemical alteration.
- Applies to
- Adult age estimation from teeth
- Indicators
- Attrition, pulp recession, cementum deposition
- Also measured
- Secondary dentine, chemical alteration
Common questions
Why are degenerative methods less precise than developmental methods?+
Wear and structural change accumulate at rates that vary widely with diet, oral habits, and individual biology, so degenerative methods generally give wider age ranges than the staged tooth-formation methods used in subadults.
Which forensic cases rely on degenerative dental methods?+
Adult skeletal remains and unidentified adult bodies, where root and crown development has long finished and only wear-related and chemical changes remain informative for estimating age.
