Aim/Objective: To compare the laterally condensed gutta-percha, vertically compacted thermoplastized gutta-percha (E and Q Plus system) and cold free-flow gutta-percha (GuttaFlow). This is a volumetric analysis using spiral CT, an in vitro study. Materials and Methods: Access cavities were prepared in 60 single rooted anterior teeth; cleaning and shaping was done and obturated with three of the different techniques: group A: cold lateral; group B: vertically compacted thermoplasticized and group C: cold free-flow obturation techniques. Volume analysis was done using spiral computed tomography (CT). The percentage difference was calculated and statistically analyzed using one-way ANOVA and post hoc multiple comparison Tukey HSD tests. Results: There were statistical significant differences between group A (0.183cm 3 ) and group B (0.136cm 3 ); group A (0.183cm 3 ) and group C (0.128cm 3 ). But there was no statistical significance between group B (0.136cm 3 ) and group C (0.128cm 3 ). Conclusion: Within the limitations of this in vitro study it can be concluded that cold free-flow obturation technique showed the highest volume of obturation, followed by the vertically condensed thermoplasticized technique. The least volume of obturation was observed in cold lateral condensation technique.
