Efficacy of three different instruments for gutta-percha removal in root canal retreatment

AUTHOR(S): Dr. Nidhi Shrivastava, Dr. Ankur Shrivastava, Dr. Marisha Bhandari and Dr. Sandhya Mishra
ABSTRACT:The present study evaluated the efficacy of retreating gutta-percha obturated root canals with Pro Taper Universal Retreatment files, R Endo Retreatment files and Hedstrom files. The canals of 60 extracted human premolars were obturated by lateral condensation technique using gutta-percha and AH plus sealer. Samples were divided into 3 groups with 20 specimens each. Chloroform was introduced into each canal to soften the gutta-percha. Pro Taper Universal retreatment files (Group1), R-Endo retreatment files (Group 2) and Hedstrom files (Group3) were used to remove the gutta-percha. Canal wall cleanliness was evaluated through Optical Stereo Microscope at 4X magnification and the area of remaining gutta-percha was calculated. The results showed that the gutta-percha remaining after retreatment was minimum in the Group 3 (Hedstrom files) followed by Group 2, whereas; Group 1 showed maximum amount of gutta-percha. Hedstrom files showed cleaner canals during retreatment as compared to Pro Taper retreatment files and R-Endo files.
