Recent Progress in Antimicrobial Strategies for Resin-Based Restoratives

Area of Science:

• Dental Materials Science
• Biomaterials Engineering
• Cariology

Background:

• Dental resin composites are widely used for tooth defect repair due to esthetics and photocuring.
• High failure rates and moderate service life, particularly due to secondary caries, are significant challenges.
• Secondary caries, often caused by bacterial biofilms, is a primary reason for restoration failure.

Purpose of the Study:

• To review recent advancements (last 5 years) in antimicrobial strategies for dental composite resins.
• To introduce novel antimicrobial agents and elucidate their mechanisms against dental caries.
• To explore the development of next-generation therapeutic dental polymer composites.

Main Methods:

• Review of recent scientific literature focusing on antimicrobial dental composites.
• Analysis of current antimicrobial strategies and agents used in composite resin formulations.
• Examination of antimicrobial mechanisms, including biofilm inhibition and acid production reduction.

Main Results:

• Antimicrobial dental composites show promise in inhibiting biofilms and reducing bacterial acid production.
• These materials can potentially decrease the incidence of secondary caries and prolong restoration longevity.
• Current research highlights encouraging results for future clinical applications of therapeutic dental restoratives.

Conclusions:

• Antimicrobial dental resins offer a promising approach to combat secondary caries and improve restoration outcomes.
• Challenges remain, including biocompatibility, antimicrobial resistance, and controlled release of agents.
• Future research should prioritize the development of efficient, durable, and intelligent antimicrobial dental resins.
