This study was carried out to assess the effect of 10, 15 and 17% ethylenediaminetetraacetic acid in vitro on smear layer removal and the degree of dentin erosion. A total of 70 closed apex single-rooted premolars were evaluated and divided into 5 groups: Group I: 4% NaOCl + 10%, EDTA, Group II: 4% NaOCl + 15%; EDTA Group III: 4% NaOCl + 17% EDTA; Group IV: 4% NaOCl and Group V: Distilled water (9 ml). They were irrigated during biomechanical preparation with 9ml of 4% NaOCl and EDTA (4 ml) for 1 minute; they were subsequently sectioned into two fragments. Each sample was subjected to a 200th monolayer gold shading (SPI - Module SputterCoater). The cervical, middle and apical thirds were observed in a 10um field and 4000x magnification with a Scanning Electron Microscope. Finally the presence or absence of smear layer and degree of erosion were evaluated according to the Torabinejad2 criteria. No statistically significant difference was found in using 10, 15 and 17% EDTA on smear layer removal in the cervical, medium and apical thirds. But 10 % EDTA removed less SL. It also became clear that 10, 15 and 17% EDTA caused dentin erosion at the three thirds evaluated. Data showed the 17% EDTA caused the most erosion.
