Summary
Fluoride prevents tooth decay by aiding enamel remineralization. A new functionalized beta-tricalcium phosphate (fTCP) system enhances fluoride
Area of Science:
- Biomaterials Science
- Dental Research
- Cariology
Background:
- Fluoride is the established standard for preventing tooth decay, enhancing enamel remineralization and altering solubility.
- Despite fluoride's success, tooth decay remains a significant oral health issue, necessitating novel therapeutic agents.
- Existing calcium-based remineralization strategies often require high ion concentrations, unlike the proposed low-dose system.
Purpose of the Study:
- To evaluate the efficacy of functionalized beta-tricalcium phosphate (fTCP) in combination with fluoride for enhanced tooth enamel remineralization.
- To investigate the potential of fTCP as a novel, low-dose mineralizing agent for dental caries prevention.
- To compare the mineral properties produced by the combination of fluoride and fTCP against fluoride, native beta-TCP, or fTCP alone.
Main Methods:
- Laboratory and clinical studies were conducted to assess the remineralization potential of fTCP combined with fluoride.
- The acid resistance and mineral characteristics of enamel treated with the combination therapy were analyzed.
- The functionalization of beta-tricalcium phosphate (β-TCP) was achieved using organic and/or inorganic molecules to control fluoride-calcium interactions.
Main Results:
- The combination of fluoride and fTCP produced a stronger, more acid-resistant mineral compared to fluoride, native β-TCP, or fTCP used individually.
- Functionalized β-TCP acts as a low-dose system, designed for integration into existing topical fluoride preparations.
- The functionalization of β-TCP creates a barrier, preventing premature fluoride-calcium interactions and facilitating mineralization.
Conclusions:
- Supplementing topical fluoride treatments with fTCP shows promise for enhancing remineralization efficacy.
- fTCP aids fluoride-based nucleation, with subsequent remineralization driven by salivary and dietary calcium and phosphate.
- Further clinical studies are warranted to fully establish the benefits of fTCP in dental caries prevention.

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...

04:01Factors Affecting Solubility
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:
00:43Complexometric Titration: Ligands
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...
