Samples of plaque and surface enamel were collected from 80 boys aged 14 years living in five communities in Ohio (USA). Mean (+/- SE) strontium concentrations in plaque were 1.43 +/- 0.18 micrograms/g (wet) and 12.34 +/- 1.63 micrograms/g (dry). For surface enamel, the mean concentration was 421 +/- 31 micrograms Sr/g. Concentrations of strontium in both plaque and enamel were significantly related to strontium levels in the drinking water. Caries prevalence as DMFS was inversely related to strontium levels in water, plaque, and enamel.
从居住在美国俄亥俄州五个社区的80名14岁男孩身上采集了牙菌斑和表层牙釉质样本。牙菌斑中锶的平均浓度（±标准误）为1.43±0.18微克/克（湿重）和12.34±1.63微克/克（干重）。对于表层牙釉质，平均浓度为421±31微克锶/克。牙菌斑和牙釉质中的锶浓度均与饮用水中的锶水平显著相关。龋病患病率（以DMFS计）与水、牙菌斑和牙釉质中的锶水平呈负相关。
