Microbial diversity in failed endodontic root-filled teeth Full Text
Chinese Medical Journal,
Chen Z et al. – Persistent intraradicular infections were present in all root–filled teeth associated with failed endodontic treatment. The current observations reveal new candidate endodontic pathogens, including as–yet–uncultivated bacteria and phylotypes that may participate in the mixed infections associated with post–treatment apical periodontitis.
