Efficacy of rotary vs. reciprocating files when used for removing root-filling residues after the use of Universal Protaper retreatment files
چکیده انگلیسی

AimThe aim of current study is to compare the efficacy of 3 different files when used as supplementary files for removing obturation residues left after the use of Protaper retreatment files.Material and methodA total of 30 freshly extracted mandibular premolars for orthodontic purpose were selected for the study. The samples were de-coronated to obtain a standard length of 16 mm. Instrumentation of the root canals with WaveOne large files was done. The samples were obturated using gutta-percha and AH Plus sealer with warm lateral compaction technique and stored for 30 days for the sealer to set. The samples were divided into 3 groups for 3 different retreatment protocols: Group 1 (Protaper RF + H-Files), Group 2 (Protaper RF + Protaper F4), and Group 3 (Protaper RF + WaveOne large). The samples were split longitudinally and observed under stereomicroscope. The images were captured and the remaining residues were calculated in percentage using Image Tool software and statistical analysis was performed using SPSS v15.ResultsGroup 1 exhibited cleaner root canal surfaces (p < 0.01) compared to groups 2 and 3 that were statistically similar (p > 0.05).ConclusionThe Protaper retreatment files, coupled with H-Files in circumferential motion, results in better removal of the root canal fillings.
