Abstract

Background and aims: Various devices have been offered to reduce the time of channel preparation. One of these devices is a modern handpiece (TEP-E10R) which is known as endogripper. This study was conducted to determine canal displacement rate of mesiobuccal root of the maxillary first molar after the preparation by two manual and rotating methods using stainless steel hand files.Methods: In this laboratory experimental study, 50 teeth taken out from human maxillary first molar were selected and divided into two groups. After access cavity preparation and placement of original files in mesiobuccal canal, digital radiography was done as the relationship between film and emission angle, and samples was fixed. Then, canals were prepared using stainless steel manually in group one and by endogripper in group two. The technique for preparing canals in both groups was passive step back in both groups. After preparation, radiography was done using master apical file as the first radiography was done. Canal displacement rate of primary radiography and original file-assisted radiography was calculated in millimeter (mm) according to adaptive images by photoshop software and radiologist assistance. The data were compared by t-test.Results: Mean deviation from original canal route in group one was 3.45±1.36 mm, higher than 1.75±1.69 obtained in group two (P=0.045). Also, mean time for CANAL PREPARATION in group one was 19.36±1.53 min, higher than 12.03±1.55 min in group two (P=0.0001).Conclusion: Using stainless steel files with reciprocal handpiece keeps on original canal route better compared to stainless steel files alone.
