Remineralizing agents: effects on acid-softened enamel
General Dentistry
|July 7, 2015
Summary
Remineralizing toothpastes, including nanohydroxyapatite (nanoHAp) and ordinary fluoridated dentifrice (OFD), show potential in protecting enamel against acid erosion. Other formulations offered less significant mineral gain in this study.
Area of Science:
- Dental materials science
- Preventive dentistry
- Biomaterials
Background:
- Dental enamel erosion is a growing concern.
- Remineralizing toothpastes aim to repair early enamel damage.
- Evaluating the efficacy of different toothpaste formulations is crucial for preventive strategies.
Purpose of the Study:
- To assess the protective effects of various remineralizing toothpastes against acid-softened enamel.
- To compare the mineral gain and microhardness changes after exposure to erosive challenges.
Main Methods:
- Fifty bovine enamel slabs with artificial erosive lesions were used.
- Treatments included nanohydroxyapatite (nanoHAp), arginine + CaCO3, KNO3 + high-F, ordinary fluoridated dentifrice (OFD), and a control.
- Microhardness testing was performed after treatments and erosive challenges.
Main Results:
- NanoHAp and OFD toothpastes showed statistically significant mineral gains (8.0% and 10.0%).
- Arginine + CaCO3 and KNO3 + high-F showed non-significant mineral gains (4.5% and 2.1%).
- The control group exhibited significant mineral loss (-11.8%).
Conclusions:
- Nanohydroxyapatite (nanoHAp) and ordinary fluoridated dentifrice (OFD) show promise in reducing enamel erosion.
- Arginine + CaCO3 and KNO3 + F formulations may help prevent the progression of erosive lesions.
- Further research is needed to confirm the long-term efficacy of these remineralizing agents.

01:31Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids
987
In the complex environment of the gastric lumen, excessive acid secretion can lead to the formation or worsening of ulcers within the delicate mucosal layer. Antacids, such as sodium bicarbonate and calcium carbonate, provide relief by neutralizing this acid, transforming it into harmless salt and water. This neutralization process raises the gastric pH from a highly acidic level of 1 to a more basic 3-4, reducing the acidity within the stomach.
However, this neutralization reaction between...

01:31Essential Minerals for Bone Health
7.2K
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...

01:19Masking and Demasking Agents
4.0K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

01:26EDTA: Auxiliary Complexing Reagents
1.6K
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...

04:01Factors Affecting Solubility
39.3K
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:

01:18Effects of EDTA on End-Point Detection Methods
764
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
