  • Title: Evidence that fluoride therapy increases trabecular bone density in a peripheral skeletal site.
    Author: Resch H, Libanati C, Farley S, Bettica P, Schulz E, Baylink DJ.
    Journal: J Clin Endocrinol Metab; 1993 Jun; 76(6):1622-4. PubMed ID: 8501171.
    Abstract:
    We measured the spinal bone density (SBD) and femoral condyle bone density (FCD) in normal and osteoporotic females (n = 219) both before and during fluoride therapy. SBD and FCD in untreated osteoporotics were significantly lower (P < 0.05) than those in the age-matched controls. SBD and FCD were correlated in the untreated (r = 0.62; P < 0.0001) as well as in the fluoride-treated osteoporotics (r = 0.42; P < 0.0001). SBD and FCD were significantly increased (P < 0.05) in response to fluoride therapy. The average rates of increase in FCD and SBD were similar (1.3 +/- 1.3 vs. 1.24 +/- 1.4 mg/cc.month). We conclude that the osteogenic action of fluoride is not limited to the axial skeleton. An increase in trabecular bone density also occurs at peripheral weight-bearing sites such as the femoral condyle.
