The purpose of this study was to attempt to correlate possible etiologic factors with the occurrence of occlusal tooth wear in a young Saudi population. The material comprised 90 individuals with a mean age of 22 years within a range of 19-25 years. A dentition wear index, in addition to anterior and posterior wear subindices were derived from tooth-by-tooth evaluations of casts. Factors found to correlate significantly with increased occlusal wear were bruxism, biting habits such as pen- and nail-biting, use of an indigenous chewing-stick called miswak, and high intake of fruit juices. There was no correlation between subjects from differing geographic and/or climatic habitats and the severity of tooth wear. The common element of a harsh desert terrain may constitute the dominant passive abrasive etiologic factor in the present sample.
本研究的目的是试图将可能的病因与沙特年轻人群中牙合面牙齿磨损的发生情况相关联。研究材料包括90名个体，平均年龄22岁，年龄范围在19至25岁之间。除了前牙和后牙磨损子指数外，牙列磨损指数是通过对模型逐颗牙齿评估得出的。发现与牙合面磨损增加显著相关的因素有磨牙症、咬笔和咬指甲等咬物习惯、使用一种名为“miswak”的本土咀嚼棒以及高果汁摄入量。来自不同地理和/或气候栖息地的受试者与牙齿磨损严重程度之间没有相关性。恶劣沙漠地形这一共同因素可能是本样本中主要的被动磨蚀病因。
