An epidemiologic investigation of the prevalence and severity of occlusal wear was carried out in a young Saudi population. Occlusal wear was evaluated on a tooth-by-tooth basis on study casts made for 206 dental students, using an ordinal scale. The reliability of the scale was assessed by percentage inter- and intra-observer concordance. The mean occlusal wear was high for the population studied. The sample presented the highest wear scores in the incisor region, maxillary canines, and mandibular molars. Comparison with other studies of similarly aged Western populations showed a more extensive pattern of wear in the present sample, pointing to the possible role of environmental influences.
在沙特年轻人群中开展了一项关于牙合面磨损患病率及严重程度的流行病学调查。基于为206名牙科专业学生制作的研究模型，逐颗牙齿评估牙合面磨损情况，采用的是有序量表。通过观察者间和观察者内一致性百分比来评估该量表的可靠性。在所研究的人群中，平均牙合面磨损程度较高。该样本在切牙区、上颌尖牙和下颌磨牙处呈现出最高的磨损分数。与其他对年龄相仿的西方人群的研究相比，本样本中的磨损模式更为广泛，这表明环境影响可能发挥了作用。
