The purpose of the study was to examine the relationship between the longitudinal development of incisal tooth wear and periodontal conditions in 51 persons. Stone casts obtained at the ages of 15 and 27 yr were used to assess incisal wear according to a graded scale, the Incisal wear Index (IwI). The wear increase after 12 yr, delta IwI, was related to the various health index scores at the age of 15 yr, including the Plaque Index (PlI) and Gingival Index (GI) systems. The chi-square tests showed a statistically significant association between delta IwI and periodontal condition in 15-yr-olds. Thus, relatively low PlI and GI values were accompanied by relatively high delta IwI values. It was concluded that in 15-yr-olds, PlI and GI levels are clinical predictors of future wear (delta IwI) of maxillary and mandibular central incisors. Pocket depth (PD) was a less valuable clinical predictor of such wear.
该研究的目的是调查51名受试者切牙磨损的纵向发展与牙周状况之间的关系。利用15岁和27岁时获取的石膏模型，根据分级量表——切牙磨损指数（IwI）来评估切牙磨损情况。12年后的磨损增加量，即ΔIwI，与15岁时的各种健康指数评分相关，包括菌斑指数（PlI）和牙龈指数（GI）系统。卡方检验显示，15岁受试者的ΔIwI与牙周状况之间存在统计学上的显著关联。因此，相对较低的PlI和GI值伴随着相对较高的ΔIwI值。研究得出结论，在15岁的人群中，PlI和GI水平是上颌和下颌中切牙未来磨损（ΔIwI）的临床预测指标。牙周袋深度（PD）作为此类磨损的临床预测指标价值较小。
