Abstract

The absolute concentrations of these elements were obtained by calibration with the animal-bone standard of the International Atomic Energy Agency. From exfoliated deciduous incisors and canines of 193 6- and 9-year-old children living in four Finnish towns, 77 enamel samples from subjects with low and high caries (dmfs = 0 and greater than 6, respectively) were analysed. There were no statistically significant correlations between Zn and caries, or Pb and caries, but a weak positive correlation existed between Sr and caries (r = 0.341; p less than 0.001). The lead concentration in incisors (8.1 +/- 5.3 parts/10(6)) was twice as high as in canines (4.1 +/- 2.6 parts/10(6)), whereas the Sr concentration was lower (63 +/- 18 and 85 +/- 13 parts/10(6), respectively) emphasizing the importance of relating such analysis to the tooth type.

摘要

这些元素的绝对浓度是通过与国际原子能机构的动物骨骼标准进行校准而获得的。从居住在芬兰四个城镇的193名6岁和9岁儿童脱落的乳牙切牙和尖牙中，分析了77份来自低龋和高龋受试者（分别为dmfs = 0和大于6）的牙釉质样本。锌与龋齿、铅与龋齿之间均无统计学显著相关性，但锶与龋齿之间存在弱正相关（r = 0.341；p < 0.001）。切牙中的铅浓度（8.1±5.3 ppm）是尖牙中铅浓度（4.1±2.6 ppm）的两倍，而锶浓度则较低（分别为63±18 ppm和85±13 ppm），这强调了将此类分析与牙齿类型相关联的重要性。
