Abstract

AIM: This ex vivo study compared the shaping characterstics of Twisted File Adaptive and Wave One Gold file systems using Cone Beam Computed Tomography (CBCT).
Methodology: Sixty extracted human permanent mandibular first molars with mesial roots curvature angles ranging within 20-30 degrees were assigned into three groups (n=30each). Teeth were imaged (90 micron resolution) with CBCT imaging software CS9300 equipment set at 84Kv, 5mA, 10.8 second exposure and a slice thickness of 76 um to obtain a pretreatment outline of the root canals. All the scans were reoriented with respect to x, y, z axis. The canal transportation and volume of root canals was evaluated at 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 mm intervals. The mean difference in Volume and Area was done using the One-ANOVA test with post-hoc bonferroni test for inter group comparisons.
Results: Twisted File Adaptive instruments did the least modifications in the Canal Area and Volume. P values of TFA was 0.001, Wave One gold was < 0> Conclusion: Twisted File Adaptive maintained the original canal anatomy. Reciprocating instruments have a higher tendency for canals transportation as compared to Twisted File Adaptive.

Keywords: Root canal, Root canal preparation, Reciprocation.
