Comparative study of the influence of instrument taper on the fracture resistance of endodontically treated teeth-An in-vitro

Krishna Prasada L, Priyanka Yadav

Objective: The Objective of this study was to examine the influence of Instrument Taper on the Fracture Resistance of Endodontically treated roots under in-vitro experimental conditions. Methods: In total, 40 mandibular first Premolar were sectioned at approximately 15 mm from the apex. The roots were will be randomly distributed into 3 experimental groups (n = 10) and 1 control group (n = 10). The roots in group 1 will be instrumented with hand files up to file (40/.02), groups 2 with Hyflex EDM Rotary File (40/.06), Group 3 with Neoendo Neohybrid rotary File (40/.04) and Group 4 acted as un-instrumented control. After mechanical preparation, the roots were obturated with gutta-percha and sealer. A vertical load will be applied to each specimen using a universal testing machine until the roots fractured. Statistical analysis: Data will be collected and statistically analyzed. Results: The mean fracture load was 357.47 ± 110.54 N for the control group, 338.86 ± 105.23 N for group 1, 297.74 ±77.31 N for group 2, and 280.10 ± 68.51 N for group 3. However, only the difference between group 3 and the control group was statistically significant (P <.05). Conclusions: After instrumentation using hand files up to file 40/.02 and rotary files up to files 40/.04 and 40/.06, only the last appeared to change the fracture resistance of endodontically treated roots Funding source: Self.
