Summary
Short-term sodium fluoride intake in healthy adults increased serum osteocalcin levels, indicating potential stimulation of osteoblastic activity. Osteocalcin concentrations returned to baseline after treatment cessation.
Area of Science:
- Biochemistry
- Endocrinology
- Bone Metabolism
Background:
- Osteocalcin is a key biomarker for bone formation.
- Fluoride is known to affect bone metabolism, but its direct impact on osteocalcin requires further investigation.
Purpose of the Study:
- To determine if sodium fluoride administration in vivo increases osteocalcin concentration.
- To assess the effect of short-term fluoride intake on other bone and mineral metabolism markers.
Main Methods:
- Seven healthy males received sodium fluoride for 3 weeks.
- Fasting levels of calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone, urea, creatinine, and osteocalcin were measured at baseline, during treatment, and 6 weeks post-treatment.
Main Results:
- Serum osteocalcin concentrations significantly increased after 3 weeks of sodium fluoride administration.
- No significant changes were observed in calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone, urea, or creatinine.
- Serum osteocalcin levels returned to baseline 6 weeks after fluoride cessation.
Conclusions:
- Short-term sodium fluoride administration in healthy individuals elevates serum osteocalcin.
- These findings suggest that fluoride may stimulate osteoblastic activity.
