Essential Minerals for Bone Health

Essential 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...

Acid Attack on Concrete

Acid Attack on Concrete

When acids come into contact with concrete, they initiate a chemical reaction that dissolves the hydrated cement paste. This process leads to softening and structural weakening of the concrete. This issue is commonly observed in environments such as chimneys, sewers, and industrial settings. The severity of the damage increases as the pH of the water interacting with the concrete drops below 6.5. In particular, a pH under 4.5 can cause significant concrete damage.
The rate at which hydrogen...

Area of Science:

Biomaterials Science
Dental Materials
Regenerative Medicine

Background:

Tooth and bone damage can lead to significant health issues.
Hydroxyapatite (HAp) is a key component of natural bone and teeth.
Developing effective methods for surface repair is crucial for restorative applications.

Purpose of the Study:

To investigate the efficacy of hydroxyapatite (HAp) coating for repairing damaged tooth and bone surfaces.
To evaluate the mechanical properties and chemical stability of HAp coatings.
To assess the biocompatibility of HAp coatings with osteoblastic cells for potential applications.

Main Methods:

Hydroxyapatite (HAp) colloidal solution immersion method was used to coat scratched human tooth and HAp disk surfaces.
Surface morphology was analyzed after 1-3 months of immersion.
Vickers hardness test and Ca2+ ion concentration measurements assessed mechanical properties and chemical stability under acidic conditions.
Cellular behavior (adhesion, growth, proliferation) of MC3T3-E1 cells was examined on HAp-coated surfaces.

Main Results:

Remarkable recovery of damaged surfaces was observed after HAp coating.
HAp coatings demonstrated good adhesion and chemical stability, with no significant Ca2+ ion loss under acidic treatment.
HAp coatings did not adversely affect the adhesion, growth, or proliferation of MC3T3-E1 cells for up to 21 days.

Conclusions:

Hydroxyapatite coating is effective in repairing scratched tooth and HAp disk surfaces.
The HAp coating exhibits excellent mechanical and chemical stability, suitable for demanding applications.
HAp coatings show promising biocompatibility, supporting osteoblast cell activity for maxillofacial and orthopedic applications.
