The relation between caries prevalence and strontium concentrations in drinking water, plaque, and surface enamel
M. E. Curzon
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.
