Abstract

The concentrations of Ca, Mg, Mn, Sr and Zn in supra- and subgingival calculus collected from mandibular anterior teeth mainly of the same persons were analyzed with atomic absorption spectrophotometry. The results showed highly significantly (P less than 0.001) greater Zn and Sr concentrations in subgingival samples. The mean value of Zn was 5.4 times higher in subgingival calculus than in supragingival calculus. In contrast, the concentration of Mn was significantly (P less than 0.01) higher in supragingival calculus. The difference in the concentration of Mg in supra- and subgingival calculus was highly significant (P less than 0.001) only when samples from the same person were compared. The concentration of Ca was very similar in both types of calculus and individual variations were very small.

摘要

采用原子吸收分光光度法对主要取自同一人群下颌前牙的龈上和龈下牙石中钙、镁、锰、锶和锌的浓度进行了分析。结果显示，龈下样本中的锌和锶浓度显著更高（P<0.001）。龈下牙石中锌的平均值比龈上牙石高5.4倍。相比之下，龈上牙石中的锰浓度显著更高（P<0.01）。仅在比较同一人的样本时，龈上和龈下牙石中镁浓度的差异才具有高度显著性（P<0.001）。两种牙石中钙的浓度非常相似，个体差异很小。
