With a greater number of people living longer and tending to retain many natural teeth, the problems associated with tooth wear are likely to place greater demands upon dental professionals in the future. Several attempts have been made to develop an index to measure tooth wear, for use at both the individual and population level. A review of these indices is undertaken, and difficulties experienced with the tooth wear index (TWI) of Smith & Knight (1984) in a large adult dental health survey is discussed. In the elderly population the scoring criteria of the TWI proved to be difficult to apply without additional qualification, and in cases of extreme wear a five-point ordinal scale was found to be inadequate to describe the range of wear observed. The concept of "pathological" levels of wear proposed by the TWI are challenged and modification to the index suggested for use among the elderly population.
随着越来越多的人寿命延长且倾向于保留许多天然牙，与牙齿磨损相关的问题未来可能会给牙科专业人员带来更大的需求。人们已经多次尝试开发一种用于个体和群体层面的牙齿磨损测量指数。本文对这些指数进行了综述，并讨论了在一项大型成人牙齿健康调查中史密斯和奈特（1984年）的牙齿磨损指数（TWI）所遇到的困难。在老年人群中，TWI的评分标准在没有额外限定的情况下难以应用，并且在极度磨损的情况下，发现五分序数量表不足以描述所观察到的磨损范围。TWI提出的“病理性”磨损水平的概念受到质疑，并建议对该指数进行修改以用于老年人群。
