CE Hours: 1.0

Description: A novel 2-part varnish system containing chitosan nanoparticles (part 1) and chitosan-grafted hydroxyapatite precursor nanocomplex (part 2) was developed to condition the root-end dentin using the principle of biomineralization while rendering both antimicrobial efficacy and bioactivity. This in vitro study aimed to characterize and assess the effectiveness of the chitosan nanoparticles and chitosan-grafted hydroxyapatite precursor nanocomplex containing self-mineralizing antibacterial tissue repair varnish to condition as well as seal rootend dentin during endodontic microsurgery.

  • Describe the main properties of the varnish system developed for root end-dentin
  • Discuss the mechanism of action of the varnish system on root-end dentin
  • List the benefits of root-end dentin biomineralization
