Abstract

<p><b>Abstract : </b>In the previous study, we have reported that generated hydroxyl radical (•OH) from Cu<sup>2+</sup> and H<sub>2</sub>O<sub>2</sub> mixed solution had bactericidal effect and also changed shape of the smear layer of root canal wall into hyaloid structure. This hyaloid structure was removed with EDTA. In this study, we examined changing form of hyaloid structure on treatmen time of Cu<sup>2+</sup> and H<sub>2</sub>O<sub>2</sub> mixed solution, and also examined changing form of hyaloid structure after using EDTA, by SEM observation. In the results, the hyaloid structure was formed after 1 min irrigated by Cu<sup>2+</sup> and H<sub>2</sub>O<sub>2</sub> mixed solution, and growing by irrigation time. When irrigate root canal wall with Cu<sup>2+</sup> and H<sub>2</sub>O<sub>2</sub> mixed solution over 2 min and then using EDTA, collagen fiber and layer were observed clearly without destroy of orifices of dentinal tubules.</p>
