reference values are given for bone tissue from 76 control subjects ( 0.08 +/- 0.05 % of bone ash ) , from two groups of 117 and 102 untreated osteoporotic patients ( 0.05 +/- 0.03 % and 0.08 +/- 0.05 % , respectively ) , from 166 sodium fluoride-treated osteoporotic patients ( mean bone fluoride content varying from 0.24 to 0.67 % , depending on the duration of therapy ) , and from 96 patients showing typical skeletal fluorosis ( mean bone fluoride content varying from 0.56 to 1.33 % , depending on the etiology of fluorosis and the relationship with the amount of fluoride ingested as well as with the duration of fluoride exposure ) .
