Objectives This study was carried out to quantitatively evaluate and compare the sealing ability of Endoflas by using different obturation techniques. Materials and Methods After 42 extracted primary maxillary incisors and canines were decoronated, their canals were instrumented with K files of size ranging from #15 to #50. In accordance with the obturation technique, the samples were divided into three experimental groups, namely, group I: endodontic pressure syringe, group II: modified disposable syringe, and group III: reamer technique, and two control groups. Dye extraction method was used for leakage evaluation. Data were analyzed using one-way ANOVA and Dunnett's T3 post hoc tests. The level of significance was set at p < 0.05. Results Endodontic pressure syringe had significantly less leakage than the modified disposable syringe and reamer techniques (p < 0.05). Meanwhile, no significant difference was found in the mean leakage between the modified disposable syringe and the reamer techniques. Conclusion Amongst all the techniques used in this study, endodontic pressure syringe could be preferred as an obturation technique in primary teeth when used with Endoflas obturation material because of its potential to provide good apical seal.
