Iron Oxide-Based Magnetic Nanoparticles in Oral Infection Control

Area of Science:

• Biomaterials Science
• Nanotechnology
• Oral Microbiology

Background:

• Oral infections present challenges due to biofilms, antibiotic resistance, and drug delivery limitations.
• Iron oxide-based nanoparticles (IONPs) offer unique magnetic properties, biocompatibility, and tunable morphology for therapeutic applications.

Purpose of the Study:

• To review the antibacterial mechanisms and therapeutic applications of magnetic nanoparticles (MNPs) in controlling oral infections.
• To highlight the potential of MNPs in overcoming conventional antibiotic limitations and enabling precise oral disease management.

Main Methods:

• Comprehensive literature review of studies on MNPs in oral infectious diseases.
• Analysis of MNPs' antibacterial mechanisms, including biofilm disruption, magnetothermal therapy, and ROS-mediated killing.
• Exploration of MNPs' applications in various oral conditions like caries, periodontitis, and osteomyelitis.

Main Results:

• MNPs demonstrate multimodal antibacterial effects, effectively targeting biofilm-rich oral sites.
• Applications span caries, endodontic infections, periodontitis, peri-implantitis, and jaw osteomyelitis.
• MNPs facilitate rapid pathogen detection through magnetic enrichment and point-of-care platforms.

Conclusions:

• MNPs present a promising strategy for advanced oral infection control, complementing traditional antibiotics.
• Key challenges include navigating the oral microenvironment, ensuring long-term biocompatibility, and facilitating clinical translation.
• Future research should focus on theranostic platforms and microbiota modulation for enhanced efficacy.
