The aim of the present study was to investigate the significance of some factors associated with occlusal tooth wear in a selected high-wear Swedish sample. The material comprised 59 subjects having a mean age of 35 yr within the range 16-70 yr, the criteria for selection being a full or nearly full complement of natural teeth, and the presence of definite clinical signs of occlusal wear. A dentition wear index was derived from a tooth-by-tooth evaluation of casts. The results showed that men had significantly greater wear than women. Other factors which were found to correlate significantly with increased occlusal wear were: age, increased bite force, decreased occlusal tactile sensitivity, increased endurance time, and reduced tendency for crowding in the dental arches. In the salivary analysis, it was found that low buffer capacity and low rate of secretion were significantly correlated with high wear. Cephalometric variables shown to be correlated with increased wear were retroclination and position of maxillary incisors, and greater interincisal angle. The results from this study also suggest that the associations of attrition with certain dentoalveolar morphologic features are similar in the present contemporary sample and various noncontemporary populations.
本研究的目的是调查瑞典一个选定的高磨损样本中与牙合面牙齿磨损相关的一些因素的重要性。研究材料包括59名年龄在16至70岁之间、平均年龄为35岁的受试者，入选标准是天然牙列完整或接近完整，且存在明确的牙合面磨损临床体征。牙列磨损指数是通过对模型进行逐颗牙齿评估得出的。结果显示，男性的磨损明显大于女性。其他与牙合面磨损增加显著相关的因素有：年龄、咬合力增加、牙合面触觉敏感性降低、耐力时间增加以及牙弓拥挤倾向降低。在唾液分析中发现，缓冲能力低和分泌速率低与高磨损显著相关。显示与磨损增加相关的头影测量变量是上颌切牙的舌倾和位置以及更大的切牙间角。本研究结果还表明，在当代样本和各种非当代人群中，磨耗与某些牙槽形态特征的关联相似。
