Objectives: Current dental resins exhibit polymerization shrinkage causing microleakage, which has the potential to cause recurrent caries.Our objectives were to create and characterize low-shrinkage-stress (LSS) composites with dimethylaminododecyl methacrylate (DMADDM) as an antibacterial agent to combat recurrent caries.Methods: Triethylene glycol divinylbenzyl ether and urethane dimethacrylate truvisionhealthftp.com were used to reduce shrinkage stress.DMADDM was incorporated at different mass fractions (0%, 1.5%, 3%, and 5%).

Flexural strength, elastic modulus, degree of conversion, polymerization stress, and antimicrobial activity were assessed.Results: The composite with 5% DMADDM demonstrated higher flexural strength than click here the commercial group (p p Streptococcus mutans (S.mutans) biofilm CFUs compared to commercial control (p p S.mutans biofilms and much lower polymerization shrinkage-stress, while maintaining excellent mechanical characteristics.The new composite is promising for dental applications to prevent secondary caries and increase restoration longevity.
