Abstract: 

Background & Aim: MTA is used frequently in dentistry. Root MTA is produced in Iran recently.This in vitro study assessed the shear bond strength of Root MTA using etch and rinse and self etch bonding systems.
Materials & Methods: In this in vitro study, 20 acrylic blocks with a central hole (6X2mm) were prepared and filled with the Root MTA. Bonding systems of Single Bond (etch and rinse) and Clearfil SE Bond Bond (self etch) were applied on the Root MTA. Z100 composite tubes (2X2mm) were bonded to prepared surfaces. The shear bond strength was estimated by Universal testing machine in MPa. The data were subjected to t-test for statistical analysis.
Results: Mean shear bond strength of Root MTA to composite were 4.71
±1.77 and 4.79±1.88 MPa using Single Bond and Clearfil SE Bond systems respectively. The difference between tow materials was not statistically significant.
Conclusion: As suggested by the result of this research, the shear bond strength of Z100 composite to Root MTA were comparable using etch and rinse and self etch bonding systems.
