Dental Adhesive Peptides Nanonets as Multifunctional Therapy for Caries

Area of Science:

• Biomaterials Science
• Dental Research
• Nanotechnology

Background:

• Dental caries presents significant challenges due to resilient biofilms and demineralization.
• Current treatments struggle with effective biofilm control and enamel repair.

Purpose of the Study:

• To develop novel adhesive nanonets for targeted dental caries management.
• To leverage arginine peptides and sodium monofluorophosphate for enhanced therapeutic effects.

Main Methods:

• Structural screening identified FmocFFRRR peptide for nanonet construction.
• Multifunctional nanonets (F@MFP) were co-assembled with sodium monofluorophosphate (MFP).
• Evaluated nanonet adhesion, S. mutans capture and killing mechanisms, anti-biofilm activity, and enamel remineralization potential.

Main Results:

• F@MFP nanonets demonstrated robust adhesion to enamel and effective capture/killing of S. mutans.
• Nanonets inhibited biofilm formation and dismantled mature biofilms by downregulating virulence genes.
• F@MFP acted as a fluoride reservoir, inhibiting demineralization and promoting remineralization.
• In vivo studies confirmed superior caries-inhibiting efficacy of F@MFP.

Conclusions:

• The F@MFP multifunctional platform offers integrated dental adhesion, capture-and-kill antibacterial action, anti-biofilm properties, and enamel repair.
• This novel approach presents a promising paradigm for targeted dental caries therapy.
