Aim: To evaluate and compare the vertical and horizontal root fracture resistance of primary maxillary incisors obturated with zinc oxide eugenol, vitapex, and endoflas. Materials and Methods: The present research is an in vitro comparative study. Eighty extracted primary maxillary incisors, selected by random sampling method were allocated to four groups depending on the type of material used for obturation, Group I: Control group. Group II: Zinc Oxide Eugenol. Group III: Vitapex Group IV: Endoflas. Specimens were loaded vertically and horizontally by a conical spreader tip affixed to an Instron testing machine until the root fractured. The load at fracture and the pattern of fracture were recorded. Results: Results were compiled and analyzed statistically by using one way ANOVA followed by Tukey’s post hoc Test and Unpaired t-test for comparison of force between amongst groups. The load at which fracture occurred was significantly higher for Endoflas followed by Zinc oxide eugenol, Vitapex, and was least in the control group. Conclusion: Within the limitations of this in-vitro research, it can be concluded that both the vertical and horizontal root fracture resistance was highest in Endoflas followed by Vitapex and zinc oxide eugenol which showed similar fracture resistance and was least in the control group. The proposed obturating materials provided resistance to occlusal load that is higher than the physiologic chewing force in children.
