Brief Summary

Aim To evaluate in vivo the shaping ability of the canal with 3 different single-file systems: Reciproc Blue, WaveOne Gold and XP Endo-Shaper, using cone beam computed tomography and 3D reconstructions to measure canal volume increase, centering ability of the instruments and canal transportation in human premolars in vivo. Methodology Thirty human lower premolars were randomly divided into three groups, in which root canals were prepared using one of these single-file systems: Reciproc Blue, WaveOne Gold, and XP EndoShaper. Root canals were scanned before and after root canal preparation by using CBCT and 3D reconstruction was carried out to evaluate canal volume increase, centering ability of the instrument and canal transportation for each group. Statistical analysis was made for each variable to determine statistically significant differences between groups.

Endodontic Disease; Root Canal Infection

root canal preparation; single-file preparation techniques; 3D reconstruction

Outcome Measures

Primary Outcomes (3)

• Root canal volume increase in cubic millimetres after root canal preparation by using the volume command in the Rhinoceros 5.0 software

  The total volume of the root canal measured before and after root canal preparation by using the volume command in the Rhinoceros 5.0 software which gives the volume of a solid in cubic millimetres.

  One day

• Root canal transportation after preparation assessed by superimposing three-dimensional reconstruction images of pre- and post-preparation

  Deviation of the original anatomy of the canal to the mesial or distal wall after root canal preparation evaluated by superimposing three-dimensional reconstruction images of the canal before and after preparation.

  One day

• Centring ability of the instruments used to prepare the root canal assessed by determining if canal was enlarged equally to each of its walls

  Ability of the instruments used for root canal preparation to equally enlarge all of the canal walls, evaluated by analysing superimposed three-dimensional reconstructed images of before and after root canal preparation.
