A possible connection has been suggested between strontium and a low prevalence of dental caries. An investigation of this subject was initiated by measuring the strontium content of deciduous teeth by atomic absorption spectrophotometry in different regions in Finland. The material analysed consisted of a total of 2,482 tooth crowns and 392 tooth roots. The results showed that the Sr content of the tooth crowns in northern Finland was about two-fold that in the south, about 400 and 200 mug/gCa, respectively. The difference was apparently caused by corresponding differences in dietary strontium. The tooth roots contained much more Sr than the crowns, about 600 and 200 mug/gCa, respectively, in southern Finland, presumably owing to changes occurring in the dietary habits of the child during the development of the crowns and roots of the deciduous teeth.
锶与龋齿低患病率之间可能存在关联。通过用原子吸收分光光度法测量芬兰不同地区乳牙的锶含量，对这一课题展开了调查。所分析的材料共有2482个牙冠和392个牙根。结果显示，芬兰北部牙冠的锶含量约为南部的两倍，分别约为400和200微克/克钙。这种差异显然是由饮食中锶的相应差异造成的。牙根中的锶含量比牙冠多得多，在芬兰南部，分别约为600和200微克/克钙，这可能是由于乳牙牙冠和牙根发育期间儿童饮食习惯发生了变化。
