Aim: Assessment of the use of Nano materials in root canal treatment from different perspectives.
Summary:
Successful endodontic treatment depends on properly reaching and cleaning all of the pulp space, eradication of all the included bacteria, shaping of the root canals as well as three dimensional obturation achieving a proper hermetic seal.
Although the chemo mechanical preparation and use of antimicrobials are effective in reducing the bacterial load, some bacteria can still persist. Irrigants can act for a short duration while intracanal antiseptic medicaments can act for longer time against microorganisms within the root canal.
Nanotechnology is progressing as a promising field that is developing in various medical and dental applications. Evaluation of cytotoxcity of nano intracanal used materials is of great importance as it affects the biological and physiological behavior of the surrounding cells. Using an intracanal irrigants, medicaments and sealers of high antibacterial efficacy and low cytotoxic effect is an optimum goal in root canal disinfection and seal which could be achieved using Nano technology. It has been confirmed that nanoparticles are much more efficient than traditional materials and appear to have superior properties in surface chemistry and bonding.
Learning objectives:
- Understanding the microbial flora of infected root canals.
- Highlighting the importance of intracanal medicaments.
- Discussing the antibacterial efficacy and biocompatibility of newly introduced Nano intracanal irrigants and medicaments.
- Comparing the solubility and adhesion properties of newly introduced Nano root canal sealers to their larger-in-scale- counterparts.
