| Title of study | Strontium concentrations in whole human saliva |
| Abstract of study | Whole unstimulated saliva samples were collected from 91 male, 14-yr-old school children in seven Wisconsin (U.S.A.) communities with varying strontium levels in their drinking water (0.22-33.6 mg/l). There was a mean concentration of 0.035 mg/l (+/- 0.001 SEM) with a range of 0.02 to 2.93 mg/l of strontium. Saliva-strontium concentrations were weakly associated with drinking-water concentrations. A negative relationship between saliva-strontium concentrations and caries prevalence was found. Strontium concentrations in saliva were related to time of ingestion of the element and levels of strontium as high as 15 mg/l occurred in saliva within 1 hr of ingesting 30 mg strontium as a single dose. |
