Abstract

Aim: T-Wire and rotating motion of two-shape (2S), M-wire and rotating motion of ProTaper Gold (PG) are the recent innovations of Nickle Titanium (NiTi) rotary file system by means of thermal treatment. Therefore, a study was planned to assess the shaping ability of 2 Shape and ProTaper Gold using cone beam computed tomography (CBCT) Materials and methods: Thirty freshly extracted mandibular first molars were selected, and Pre-instrumentation CBCT imaging was performed to attain mesial and distal dentin wall measurements followed by chemo-mechanical preparation using the following NiTi files: 2S and ProTaper Gold. Post instrumentation CBCT imaging was performed for evaluation of the volume of removed dentin, apical transportation, and centering ratio. Statistical analysis was confirmed by a suitable analysis test with significance set at 0.05r. Results: In terms of the total volume of removed dentin, apical transportation, and centering ratio there was a significant difference noted between the tow-shape and ProTaper Gold. 2Shape performed better in all aspects compared to ProTaper Gold. Conclusion: Two-shape (2S) maintained better original canal anatomy and volume of removed dentin was also less during chemo-mechanical preparation when compared to ProTaper Gold. Clinical significance: Two-shape (2S) system when used clinically in patients may perform better and produce less canal transportation and canal preparation will be more centered as compared to the ProTaper Gold system.
