Abstract:
Successful endodontics procedure is based on complete biomechanical preparation and three dimensional obturaion. Root canal irrigation is to eliminate necrotic pulp tissue remains and smear layers. There are limited reported studies on comparison of nanoparticle based irrigants. Therefore, it is of interest to assess the efficacy of nanoparticle, EDTA irrigants and sodium hypochlorite on smear layer elimination and surface roughness on root canal dentine. Sodium hypochlorite followed by Silver nanoparticle based irrigant showed good efficacy in removal of smear layer. Silver nanoparticle showed minimal surface roughness of root canal dentine compared to sodium hypochlorite and EDTA.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
Masking and Demasking Agents
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...
