Summary
A novel nanocoating repels acquired salivary pellicle (ASP), overcoming a major barrier to enamel remineralization for dental caries prevention. This strategy enhances mineral deposition for effective enamel restoration.
Area of Science:
- Biomaterials Science
- Dental Research
- Nanotechnology
Background:
- Dental caries treatment is limited by acquired salivary pellicle (ASP) inhibiting enamel remineralization.
- ASP passivates enamel surfaces, reducing the effectiveness of current mineralization strategies.
Purpose of the Study:
- To develop an ASP-repelling nanocoating to enhance enamel remineralization.
- To investigate the efficacy of a novel nanocoating in overcoming ASP-mediated inhibition of mineralization.
Main Methods:
- Fabrication of a phase-transitioned bovine serum albumin (PTB) nanocoating using amyloid-like protein self-assembly.
- Evaluation of PTB nanocoating's antifouling properties against ASP adsorption.
- Assessment of PTB-driven biomineralization and enamel remineralization under simulated oral conditions (in vitro and in vivo).
Main Results:
- PTB nanocoating demonstrated robust antifouling properties, effectively inhibiting ASP adsorption.
- PTB treatment significantly enhanced calcium phosphate nucleation and crystallization for enamel remineralization.
- In vitro and in vivo studies confirmed PTB's ability to reverse ASP-induced inhibition of remineralization.
Conclusions:
- The PTB nanocoating provides a promising strategy to overcome ASP barriers in dental caries prevention.
- This approach offers a novel method for effective enamel restoration by promoting biomineralization.
- Understanding ASP-interface interactions is crucial for developing advanced remineralization therapies.

03:03Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

01:30Enzyme Inhibition
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.
01:15Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
