Oxalic acid was determined in human saliva, teeth, tartar, and in animal teeth. Saliva from dentally healthy male subjects contained 0.10 +/- 0.09 mmol/l (n = 41) and those of dentally healthy female subjects 0.18 +/- 0.17 mmol/l (n = 40). Oxalic acid in tartar from 16 patients was 3.3 +/- 1.2 mmol/kg tartar. In human teeth, oxalic acid was 1.0 +/- 0.3 mmol/kg in milk teeth (n = 12) and 0.9 +/- 0.6 mmol/kg in permanent teeth (n = 60). Human teeth were sorted into age groups and into molars, incisors and premolars. In animal teeth, oxalic acid content varied widely. The formed calcium oxalate is proposed to be a 'physiological' protective mechanism for teeth.
对人类唾液、牙齿、牙垢以及动物牙齿中的草酸进行了测定。牙齿健康的男性受试者唾液中草酸含量为0.10±0.09毫摩尔/升（n = 41），牙齿健康的女性受试者唾液中草酸含量为0.18±0.17毫摩尔/升（n = 40）。16名患者牙垢中的草酸含量为3.3±1.2毫摩尔/千克牙垢。人类乳牙中的草酸含量为1.0±0.3毫摩尔/千克（n = 12），恒牙中的草酸含量为0.9±0.6毫摩尔/千克（n = 60）。人类牙齿按年龄组以及臼齿、门牙和前磨牙进行分类。动物牙齿中的草酸含量差异很大。所形成的草酸钙被认为是牙齿的一种“生理”保护机制。
