Then, a 3mm cavity was made in apex and were filled by amalgam ( vivdentTM or Sina TM), cavit and coltosol in groups number 2 to 5. The gutta-percha was condensed by a round end tool. The samples were placed in Methylen blue for 48 hours and then by scrubbing lateral walls of the teeth, the penetration of color into root canal space was evaluated by steromicroscope. The obtained results showed that Coltosol was acted better and resulted in more significant changes compared to Amalgam vividentTM, SinaTM , Cavit and Gutta-percha.(P≤0.001) /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal" mso-tstyle-rowband-size:0 mso-tstyle-colband-size:0 mso-style-noshow:yes mso-style-priority:99 mso-style-qformat:yes mso-style-parent:"" mso-padding-alt:0cm 5.4pt 0cm 5.4pt mso-para-margin-top:0cm mso-para-margin-right:0cm mso-para-margin-bottom:10.0pt mso-para-margin-left:0cm line-height:115% mso-pagination:widow-orphan font-size:11.0pt font-family:"Calibri","sans-serif" mso-ascii-font-family:Calibri mso-ascii-theme-font:minor-latin mso-hansi-font-family:Calibri mso-hansi-theme-font:minor-latin mso-bidi-font-family:Arial mso-bidi-theme-font:minor-bidi}
