Health risks imposed by heavy-metal exposure have been known for some time, and the mercury released from dental restorations has been reported to pose a risk. In that case, a variation in basic physiological parameters would be expected in these individuals. We have chosen to examine two body mineral values, whole body potassium (WBK) and bone mineral content (BMC), in this relation by examining data available from a study of growth hormone in older men. In 43 subjects with 4 or more amalgam restorations, the mean values for the age-matched BMC values of L4, the wrist, and Ward's triangle were 111, 94 and 100 percent, respectively, and the mean lean body percent potassium value was 0.173305 +- 0.002213 (standard deviation). Compared to the values for the 20 edentulous control-group patients with no amalgam restorations, the populations were not shown to be different with respect to WBK or BMC.
