A comparative evaluation of two root canal instrumentation techniques for preparation of oval shaped root canals using cone beam computed tomography-an in vitro study

Aim & Objective: This study aimed to compare the efficacy of two instrumentation techniques: Anatomic Endodontic Technology (AET) & Anthogyr with K3 NiTi instruments in oval shaped root canals. Materials and Methods: Two groups each of 15 extracted human mandibular premolars with oval-shaped root canals were used. In group 1, canal preparation was carried out using Anatomic Endodontic Technology and in group 2, Anthogyr system both using K3 Nickel Titanium (NiTi) instruments. Irrigation was done using 3% sodium hypochlorite. Pre and post instrumentation images obtained from cone beam computed tomography were compared using Kodak dental software to assess cross sectional canal shape. Results: No significant difference was found between the two techniques with regard to preparation of oval shaped root canals. Conclusion: Anatomic Endodontic Technology (AET) did not perform better than rotary Anthogyr in oval-shaped root canals.
