Introduction: Success of pulp therapy depends on proper biomechanical preparation, disinfection of canal, dryness of canal and acquisition of proper seal by use of ideal obturating material. Though there are many obturating materials available, there is no proper consensus on the best obturating material for primary teeth. Thus the present study was done to compare and evaluate the quality of obturation using zinc oxide eugenol and endoflas with spiral computed tomography (CT).
Materials and methods: Thirty single-rooted primary teeth were selected for the study. They were debrided to the determined working length using K files and prepared for obturation. Teeth were later numbered from 1 to 30 and divided into two groups of 15 teeth each. Preobturation volume of two groups was evaluated using spiral CT followed by which group 1 was obturated using zinc oxide eugenol and group 2 with endoflas using rotary lentulospiral. Another scan with CT was done to check postobturated volumes of both groups. The volumetric analysis was done using Advantage work station software for Windows (GE System, Milwaukee). Tukey's post-hoc test, analysis of variance (ANOVA) were used to analyze statistical significance between variable.
Results: The mean preobturated volume (POV) of group 1 was 0.00042 ± 0.00001, the mean postobturated volume of group 1 was 0.00039 ± 0.00001 and the mean POV of group 1 was 95.23 ± 0.81.
The mean POV of group 2 was 0.00040 ± 0.00001, the mean postobturated volume of group 2 was 0.00038 ± 0.00001 and the mean POV of group 2 was 96.02 ± 0.10.
Statistically, the insignificant difference was observed between canals obturated with zinc oxide eugenol and endoflas.
Conclusion: It can be concluded that the percentage of the obturated volume of zinc oxide eugenol and endoflas were statistically insignificant.
