This paper describes the prevalence, pattern, and severity of incisal wear of anterior teeth in 64 dental students at an average age of 23 +/- 1.7 years with a high number of permanent teeth present. The index used to assess wear on stone casts (IwI) was shown to have good reproducibility. The results indicated that about 98% of the anterior teeth had been worn to various degrees. In both jaws central incisors were most commonly affected by incisal wear, canines followed next in order, and lateral incisors were least commonly affected. Wear of identical teeth on the right and left side tended to be bilaterally symmetrical in both jaws. The results of these initial observations suggest that data from re-examination of this study group will lend themselves to detecting possible changes of the pattern and severity of incisal wear of permanent anterior teeth.
本文描述了64名平均年龄为23±1.7岁且恒牙数量较多的牙科专业学生前牙切缘磨损的患病率、模式及严重程度。用于评估石膏模型上磨损情况的指数（IwI）显示出良好的可重复性。结果表明，约98%的前牙有不同程度的磨损。在上下颌中，中切牙最常受到切缘磨损的影响，其次是尖牙，侧切牙受影响最少。左右两侧同名牙的磨损在上下颌中往往呈双侧对称。这些初步观察结果表明，对该研究组进行重新检查所获得的数据将有助于检测恒牙前牙切缘磨损模式和严重程度的可能变化。
