Glassionemer sealer group A (n=20), mineral trioxide aggregate( MTA) sealer group B (n=20), iroot sealer group C (n=20), control group (n=10) for each group. Treated the surface of GP for each group by two disinfectant solutions (NaOCL 2.5%,&nbsp; CHX 2%).Shear bond strength( S.B.S) test was calculate by digital universal testing machine.</p> <p><strong>Results</strong>: iroot sealer (group C) with NaOCL solutions at (2.5%) increase shear bond which were significantly different P≤0.05 from CHX at (2%) and fresh control cones. glassionemer sealer (group A) gaive the lowest measured.</p> <p><strong>Conclusions: </strong>&nbsp;NaOCL solutions at 2.5% left a many pitting investigated on the GP surface. Thus it increased the bond with sealer. The quality of the surface texture and mechanical properties of GP were unaffected by a CHX solution of 2%. Therefore, they were considering as the safe disinfectant solutions for GP cones.&nbsp;</p>}, number={1}, journal={Mustansiria Dental Journal}, author={khalil Ibrahim, Nibras and Mohammad younis, Zena and A.
