All of the teeth were instrumented with Protaper Universal files, using the crown-down technique up to size 30, 0.06 taper (F3). Groups are as follows; Group 1 (Control): 5 mL distilled water (1 min), Group 2: 5 mL 17% EDTA (1 min), Group 3: 5 mL 1% phytic acid (1 min), Group 4: 5 mL 0.5% phytic acid (1 min). Root canals were irrigated between each file with 2 ml, 5% NaOCl. Photomicrographs were taken at x2000 magnification, from the coronal, middle and apical third of each specimen for evaluation. </span> </p> <p align="center" style="margin: 0cm 0cm 0pt; text-align: center; line-height: 13pt; mso-pagination: none;"> <font face="Times New Roman" size="3"> <br> </font> </p> <p style="margin: 0cm 0cm 0pt; text-align: justify; line-height: 12pt; -ms-text-justify: inter-ideograph; mso-pagination: none;"> <b> <span lang="EN-US" style=’font-family: "Tahoma","sans-serif"; font-size: 9pt; mso-ansi-language: EN-US; mso-bidi-font-family: "Arial Unicode MS";’>Results: </span> </b> <span lang="EN-US" style=’font-family: "Tahoma","sans-serif"; font-size: 9pt; mso-ansi-language: EN-US; mso-bidi-font-family: "Arial Unicode MS";’> The 1% phytic acid solution proved to be more effective than the conventional 17% EDTA solution even when the concentration was reduced by 50%. Seventeen percent EDTA solution was effective in the removal of the smear layer at the coronal and middle thirds of the root canal. However, the solution was not as effective at the apical third of the root canal. While specimens treated with the 1% phytic acid caused the highest erosion, the 0.5% phytic acid and 17% EDTA followed. </span> </p> <p align="center" style="margin: 0cm 0cm 0pt; text-align: center; line-height: 13pt; mso-pagination: none;"> <font face="Times New Roman" size="3"> <br> </font> </p> <p style="margin: 0cm 0cm 0pt; text-align: justify; line-height: 12pt; -ms-text-justify: inter-ideograph; mso-pagination: none;"> <b> <span lang="EN-US" style=’font-family: "Tahoma","sans-serif"; font-size: 9pt; mso-ansi-language: EN-US; mso-bidi-font-fa}, number={3}, publisher={Atatürk Üniversitesi}
