Effect of dental monomers and initiators on Streptococcus mutans oral biofilms

Dimethacrylate-based dental resins generally result in incomplete conversion of the monomers to polymers due to vitrification. As a result, measurable levels of leachables can elute from the materials after polymerization [1 –3]. Some of the leachable components may exhibit a burst release that declines over time, but in other cases leachables have been shown to elute for extended periods [4], especially if the final degree of conversion (DC) of the polymeric material is low [5]. Leachables are well-established as one of the primary causes for cytotoxicity to mammalian cells associated with dental polymers and composites [6–8].
