Aim: The aim of this study was to compare the effects of Ethylen glycol tetra acetic acid (EGTA) and EDTA for their smear layer removal capability using scanning electrone micrscopy technique.

Methods & Materials: A group of 28 single rooted teeth were instrumented to size 60 master file. Four teeth were also kept as control while the remaining teeth were devided into two groups. Group A: in which 12 teeth were irrigated with 10 ml of 17% EGTA for 2 minutes. Group B: consisted of 12 teeth irrigated with 10 ml of 17% EDTA for 2 minutes. Both groups were then irrigated with 10 ml of 5% Naocl. The control group were just irrigated with 10 ml of 5% Naocl. All teeth in then the control group were only irrigated with 10ml of 5% Nacl. Specimeus were then sectioned longitudinally. A scanning electrone microscope was wsed to in vetig ate the intenal surfaces of the cannal.

Results: EGTA chelated dentin surface more conservatively than EDTA without causing erosion.

Conclusion: It seems that EGTA can be used safely to remove smear layer from tyhe cannal surfaces.
