Biofilm inhibition by an experimental dental resin composite containing octenidine dihydrochloride.

Objectives: The aim of the present study was to investigate an antimicrobial additive containing experimental resin composite with regards to its impact on biofilm formation under oral conditions.

Methods: Biofilms were established in situ on composite specimens (n=192) which contained octenidine dihydrochloride (ODH, 3 wt.% or 6 wt.
