Introduction: The present study was planned to evaluate the effectiveness of Glyde File Prep TM used in conjunction with NaOCI irrigation in the removal of smear layer produced during root canal instrumentation.
Methodology: 60 extracted mature human teeth with single canals were selected. Access opening was done and working length was established, cleansing and shaping was done upto size 60 with K – flex files with conventional step back technique. Specimens were divided into 15 sets of 4 teeth each.
Observations: Under the SEM evaluation both at the higher magnifications of 1000X and 3000X , it was demonstrated that at the cervical and middle canal levels, there was significantly cleaner appearance in EDTA group compared to NaOCl group. Also coronal and middle thirds of Glyde had much less smear layer compared to the respective levels in NaOCl group. However, the difference was not consistent at the apical levels. There was a significant difference in the canal cleanliness between the apical levels of liquid EDTA group compared to both Glyde groups.
Results and conclusion: It can be concluded that gel preparations of EDTA are not as effective in smear layer removal as liquid EDTA preparations
