Volumetric analysis of root filling with cold lateral compaction, Obtura II, Thermafil, and Calamus using spiral computerized tomography: An In vitro Study

Aim: The aim of the present study is volumetric analysis of root canal filling with cold lateral compaction, Obtura II, Thermafil, and Calamus using spiral computerized tomography (SCT). Materials and Methods: Root canals of eighty mandibular premolars were instrumented using rotary ProTaper, and the volume of the canal space was measured using spiral computerized tomography (SCT). The teeth were divided into four groups of twenty teeth each, and root canals filled by lateral compaction technique, Thermafil carriers, Obtura II, and Calamus techniques, respectively. AH Plus was used as a sealer with all techniques. The filled volume in each canal was measured using SCT, and the percentage of obturated volume (POV) was calculated. The data were statistically analyzed using ANOVA, Kruskal–Wallis test, and Mann–Whitney U-test. Results: The four groups were comparable in canal volume. The overall POV was 78.11%, 85.72%, 82.50%, and 87.89% for lateral compaction, Thermafil, Obtura II, and Calamus, respectively (P < 0.05). Conclusion: The greatest POV was obtained with Calamus and Thermafil. Voids were seen in all root fillings.
