Composition of saliva plays an important role in defining the dental caries risk for an individual. The role of trace elements present in saliva on dental caries is still not clear. Thus this study was designed to evaluate the effect of certain salivary trace elements like copper, potassium, fluoride, selenium and lead on the caries experience of children.
60 subjects in the age group of 3-15 years were selected and divided into two groups, caries active and caries free. 5 ml of unstimulated saliva from each subject was collected and analyzed for the levels of trace elements using Induced Couple Plasma Spectrophotometer (ICP-OES).
Copper and Fluoride levels were significantly higher in caries free as compared to caries active individuals whereas Lead was significantly higher in caries active as compared to caries free children (p-value<0.05). Potassium and Selenium though present in appreciable amounts did not show any significant difference between the two groups (p-value>0.05).
In caries free subjects, copper and fluoride levels were significantly higher while the level of lead was lower as compared to caries-active children. Potassium and selenium did not show any significant differences within the two groups.
唾液成分在确定个体患龋齿风险方面起着重要作用。唾液中微量元素对龋齿的作用仍不明确。因此，本研究旨在评估某些唾液微量元素如铜、钾、氟、硒和铅对儿童龋齿经历的影响。
选取60名3至15岁的受试者，分为两组，即患龋活跃组和无龋组。收集每位受试者5毫升未刺激唾液，使用电感耦合等离子体光谱仪（ICP - OES）分析微量元素水平。
与患龋活跃个体相比，无龋个体的铜和氟水平显著更高；与无龋儿童相比，患龋活跃儿童的铅水平显著更高（p值<0.05）。钾和硒虽然含量可观，但两组之间未显示出任何显著差异（p值>0.05）。
与患龋活跃儿童相比，无龋受试者的铜和氟水平显著更高，而铅水平更低。钾和硒在两组之间未显示出任何显著差异。
