Effectiveness of nanoparticles solutions and conventional endodontic irrigants against biofilm.

Context: To overcome the challenge imposed by the presence of biofilm and reach significant bacterial reduction of the root canals, many irrigants have been indicated during endodontic treatment, among them nanoparticles solutions.

Aims: This study aims to evaluate the effectiveness of experimental solutions containing silver and zinc oxide nanoparticles (ZnO Np) and conventional endodontic irrigants against Enterococcus faecalis biofilm, in root canals.

Methods: Seventy-six extracted human teeth were biomechanically prepared and sterilized.

Analysis of sealing ability of endodontic cements apical plugs.

Background: It is unknown whether the bioactivity of Biodentine characterized by the precipitation of hydroxyapatite and formation of tags into the dentinal tubules improve its sealing ability as an apical plug. Aim: To evaluate the sealing ability provided by Biodentine and mineral trioxide aggregate (MTA) apical plugs, with or without phosphate-buffered saline (PBS) intracanal dressing, using a glucose leakage method.

Material And Methods: The space of the canal of 100 root segments with about 12 mm long was shaped using Gates-Glidden.
