We examined the differences between the concentrations of chemical elements in caries-changed primary teeth and permanent ones with a division into the root and the crown. The study comprised 27 children aged from 4 to 11 yr and 36 adults aged from 36 to 71 yr. We examined the elements with the total reflection X-ray fluorescence method. The lowest concentrations of calcium, manganese, strontium, lead, and copper were in the roots of primary teeth compared to the roots of permanent ones. The calcium, nickel, zinc, lead, and copper concentrations were significantly higher in the roots of primary teeth than in the roots of permanent teeth. However, the zinc concentration was higher both in the root and crown of primary teeth than in permanent teeth. On the basis of our investigations, we can conclude that the content of some elements (manganese, copper, strontium, and lead) is higher in caries permanent teeth than in primary ones. The nickel and zinc concentrations are higher in the teeth of the children than the adults. However, the content of other elements (calcium, chromium, iron) is similar in both kinds of teeth.
我们研究了龋变乳牙和恒牙中化学元素浓度的差异，并将其分为牙根和牙冠两部分进行分析。该研究纳入了27名4至11岁的儿童和36名36至71岁的成年人。我们采用全反射X射线荧光法检测了这些元素。与恒牙牙根相比，乳牙牙根中钙、锰、锶、铅和铜的浓度最低。乳牙牙根中的钙、镍、锌、铅和铜浓度显著高于恒牙牙根。然而，乳牙牙根和牙冠中的锌浓度均高于恒牙。基于我们的研究，我们可以得出结论：一些元素（锰、铜、锶和铅）在龋变恒牙中的含量高于乳牙。儿童牙齿中的镍和锌浓度高于成年人。然而，其他元素（钙、铬、铁）在两种牙齿中的含量相似。
