Tooth Discoloration and Solubility of Zinc Oxide Eugenol Combined with Different Concentrations of Nano-Curcumin: An Study.

Statement Of The Problem: Due to the unfavorable properties of eugenol, the eugenol content can be reduced to improve the properties of zinc oxide eugenol (ZOE) by making a new combination of nanocurcumin called curcumin pulpal paste (CPP).

Purpose: The aim of this study was to evaluate the solubility and tooth discoloration of three concentrations of CPP compared to ZOE, and Metapex.

Materials And Method: In this study for evaluating of the solubility, five groups including ZOE, Metapex, and three concentrations of CPP (5%, 10%, and 20%) were tested.
