In estimating the age of an individual from skeletal remains, the Gustafson method uses six dental parameters. Which parameter specifically assesses the MOST age-dependent cumulative change that reflects wear from mastication?
- A Secondary dentine deposition
- B Cementum apposition
- C Attrition ✓
- D Root resorption
Correct answer: C. Attrition
Explanation
Gustafson's method uses six dental parameters each scored 0–3: attrition (wear of the occlusal surface), secondary dentine deposition, cementum apposition, root resorption, root transparency, and periodontal recession. Attrition is the most visually obvious and directly reflects cumulative masticatory wear with increasing age; it is the primary parameter. Secondary dentine and cementum apposition are also strongly age-correlated but are microscopic findings. Root resorption is less reliable as it may occur from pathology.
