|November 1, 1990
Summary
Fluoride levels in fetal teeth buds and milk teeth are stable, unlike fetal bone which has lower levels. These differences in fluoride content may stem from distinct hydroxyapatite properties in teeth versus bones.
Area of Science:
- Biomineralization
- Skeletal and dental research
- Trace element analysis
Context:
- Hydroxyapatite in teeth and bones exhibits a strong affinity for fluorine.
- Understanding fluoride binding in developing human tissues is crucial for dental and skeletal health.
- Previous research suggests age-related changes in bone fluoride content.
Purpose:
- To investigate potential differences in fluoride binding between dental and skeletal hydroxyapatite.
- To quantify fluoride levels in human fetal teeth buds, milk teeth, and femur.
- To explore the implications of observed fluoride distribution.
Summary:
- Fluoride levels were determined in human fetal teeth buds, milk teeth, and femur.
- A stable fluoride content was observed in teeth buds and milk teeth.
- Fetal bone exhibited the lowest fluoride levels, which are known to increase with age.
Impact:
- The findings suggest that differences in fluoride levels may be attributed to variations in the physicochemical properties of dental versus bone hydroxyapatite.
- This research could inform strategies for optimizing fluoride incorporation for improved dental and bone health.
- Highlights the need for further investigation into the regulatory mechanisms of fluoride binding in different tissues.

Overview
01:18The Bone Matrix
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
01:31Essential Minerals for Bone Health
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:21Skeleton and Calcium Homeostasis
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
01:27Roles of Electrolytes: Calcium and Phosphate
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.

01:26Minerals
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
