The present study was undertaken to compare and evaluate the remaining dentin thickness of root canals with ProTaper Golr, NeoEndo and Revo-S systems using cone beam computed tomography for analysis.
Materials and Methods: Forty five extracted human mandibular molars having were collected. Teeth were randomly assigned to three groups (n=15). Samples were decoronized by maintaining root length. Pre-instrumentation cone beam computed tomography scan was done after stabilizing the samples on wax blocks. The working length was determined at 1 mm short from the apical foramen by using a ISO 15 K-fi le tip protruding at apical foramen. Preparation was carried out according to the manufacturer’s instructions. Finally, canals were instrumented upto apically for each group. After each instrumentation, root canals were irrigated with 2ml of 3% sodium hypochlorite solution followed by 2 ml of 17% EDTA solution. Final irrigation was done with 5ml of saline. Post instrumentation cone beam computed tomography scans of all samples in the 3 groups were acquired.
Result: revo-s and NeoEndo removed less dentin than Protaper Gold file system.
Conclusion: Protaper Gold, NeoEndo and Revo-S showed statistically significant difference in remaining dentin thickness over the different intervals of root canal length. Therefore, it was concluded that Protaper Gold file system removed more dentine than Revo- S and NeoEndo file system.
