Kvaal Method
Definition
A non-destructive radiographic method that measures pulp-to-tooth ratios at defined reference points on periapical radiographs to estimate age from secondary dentine deposition. Published by Kvaal et al. in 1995.

Common questions
How does the Kvaal method compare to Gustafson's method for age estimation?+
Gustafson's original method required sectioning extracted teeth and scoring several histological criteria, while Kvaal's approach works from radiographs of teeth still in the mouth, making it usable on living individuals and preserved remains alike.
What limits the accuracy of the Kvaal method?+
Radiograph angulation and image quality affect the measured ratios, and the original regression equations were built on a specific population, so accuracy can drift when applied to different ancestry or age groups without local calibration.
