The amounts of cobalt and chromium released to the saliva in individuals wearing cobalt-chromium partial dentures have been measured. Saliva was collected during a 5-min period, both with and without dentures in the mouth, and the two samples compared. More than 80% of the 30 cases showed increased amounts of metals with the denture in the mouth. Newer and larger dentures liberated more than did older and smaller ones. The median increase in chromium was approximately twice that of cobalt.
对佩戴钴铬合金局部义齿的个体唾液中释放的钴和铬含量进行了测量。在口腔中佩戴义齿和不佩戴义齿的情况下，均在5分钟内收集唾液，并对两个样本进行比较。30例病例中，超过80%的病例显示口腔中佩戴义齿时金属含量增加。新的、较大的义齿释放的金属比旧的、较小的义齿更多。铬的中位数增加量约为钴的两倍。
