An In-Vitro Evaluation of Remaining Dentine Thickness through Cbct Using Different Files

Abstract

Aim: The study was to evaluate the effect of multiple file system (Revo S) versus single file system (one shape) on the dentine thickness in the root canal. Materials and Methods: In this study, 30 freshly extracted human mandibular first molars were taken. Mesiobuccal canal of mandibular first molar was selected for this study. All the teeth were categorized into two groups namely Group I: Revo-S Group II: One Shape. Endodontic access was prepared in each tooth, and working length was determined using 15-k file. Pre-operative cone beam computed tomography (CBCT) scan of the teeth was taken. Cleaning and shaping of the canal was done according to the manufacturer's instruction of file system. Post instrumentation CBCT scan of teeth was taken. The difference in the area was calculated and statistical difference was analyzed. Result: One shape removed less dentin than Revo-S file system. Conclusion: Revo-S and One Shape showed statistically signifi cant difference in remaining dentin thickness over the different intervals of root canal length. Therefore, it was concluded that One Shape file system removed less dentine than Revo-S file system
