The dentitions of adult Arikara Indians from the Larson site (39WW2) were examined to determine the frequency and etiology of noncarious interproximal grooves. The observations included groove morphology, loci and association with dental pathology. Approximately 30% of the individuals exhibit one or more pronounced grooves. The use of dental probes in conjunction with dietary grit is the likely responsible for interproximal grooves in this population sample.
对来自拉森遗址（39WW2）的成年阿里卡拉印第安人的牙列进行了检查，以确定非龋性邻面沟的发生率和病因。观察内容包括沟的形态、位置以及与牙齿病变的关联。约30%的个体有一条或多条明显的沟。在该人群样本中，使用牙探针并伴有饮食中的沙砾可能是导致邻面沟的原因。
