Abstract

Objective: The present study aims to validate the efficacy of age assessment by the Brothwell tooth wear chart, uniquely using skulls of recorded known age at death. Materials and Methods: Fifty Chinese skulls, of known age recorded at death, ranging from 16 to 62 years, were used. All the skulls were anonymized laid out, numbered 1–50, and using randomized tables. A 70-mm, ×3 magnification glass with light (Rolson, Ruscombe, Twyford, Berkshire, United Kingdom) was used to evaluate tooth wear patterns, and the age assessed using newly devised “age calculator” based on the Brothwell Chart. Results: The recorded age at death versus the estimated age derived from the Brothwell chart was statistically compared the weighted kappa score = 0.877, suggestive of a “very good” strength of agreement. Conclusion: The Brothwell chart, based on tooth wear, can be used as a consistent method of age assessment, allowing for easier and more rapid data collection with no loss of overall accuracy.
