Tooth wear is frequently used as a method of ageing skeletal remains. Fundamental to this method is the ability to measure the amount of tooth wear. The Brothwell chart based on the Miles method of ageing, uses simple ordinal scoring and is frequently used by archeologists. The purpose of the present investigation was to evaluate the accuracy of simple ordinal scoring in recording tooth wear and ageing skulls. A group of Chinese skulls of known age at death was used. The age range was from 16 to 60 years. A single score per molar tooth was used to record occlusal wear. The data were analysed by regression methods using BMDP statistical software. The results showed that molar tooth wear continues throughout the life of the individual. The first molar teeth wear significantly more quickly than do second molar teeth. Use of a simple ordinal score method for recording wear gives an inaccurate estimate of an individual skull's age at death with a very wide 95% confidence interval.
牙齿磨损常被用作推断骨骼遗骸年龄的一种方法。这种方法的基础是能够测量牙齿磨损的程度。基于迈尔斯老化方法的布罗斯韦尔图表采用简单的序数评分，考古学家经常使用。本研究的目的是评估简单序数评分在记录牙齿磨损和推断头骨年龄方面的准确性。使用了一组已知死亡年龄的中国头骨。年龄范围为16至60岁。每颗磨牙使用单一分数记录咬合面磨损情况。使用BMDP统计软件通过回归方法对数据进行分析。结果表明，磨牙磨损在个体的一生中持续存在。第一磨牙的磨损速度明显快于第二磨牙。使用简单序数评分法记录磨损情况会对头骨个体的死亡年龄给出不准确的估计，其95%置信区间非常宽。
