Nanotechnology and its role in caries therapy

Area of Science:

• Biomaterials Science
• Nanotechnology
• Dental Research

Background:

• Dental caries is a significant oral health issue characterized by demineralization of tooth enamel.
• Early-stage caries (incipient lesions) present an opportunity for intervention and reversal.
• Traditional treatments often focus on managing established lesions, highlighting the need for novel approaches.

Purpose of the Study:

• To review recent advancements in nanotechnology for remineralizing incipient caries lesions.
• To explore biomimetic strategies for enamel synthesis utilizing nanotechnology.
• To assess the potential of nanomaterials in controlling demineralization and treating caries.

Main Methods:

• Analysis of in vitro data on apatite nanoparticles for lesion reversal.
• Development of ion-releasing nanofillers for resin composites to combat demineralization.
• In vitro investigations of apatite crystallization mimicking natural enamel structure.
• Strategies involving oriented aggregation of nanocrystallites and nanoparticle assembly via organic scaffolds.

Main Results:

• Apatite nanoparticles showed potential in reversing outer enamel lesion progression in vitro.
• Nanofillers can release calcium, phosphate, or fluoride ions under low pH conditions to control demineralization.
• Biomimetic strategies successfully mimicked the hierarchical structure of natural enamel in vitro.

Conclusions:

• Nanotechnology presents promising in vitro results for incipient caries remineralization and enamel synthesis.
• Ion-releasing nanofillers offer a strategy to control demineralization in dental composites.
• Further clinical validation is essential to confirm the therapeutic efficacy of these nanotechnological approaches in caries management.
