Aim: In an attempt to move toward exploration of the antibacterial properties of herbal products, this study evaluated the effect of how the addition of Moringa would affect the physical properties of the commercial Endofil sealer. Materials and Methods: An experimental in vitro study was performed using three experimental sealers. There were four groups in this study: Group A (ZnO/E sealer alone), Group B (ZnO/E and Moringa root), Group C (ZnO/E and Moringa leaf), and Group D (ZnO/E and Moringa leaf extract liquid). Measurements were carried out according to International Organization for Standardization (ISO) standardization 6876:2012. Moringa oleifera was added to Endofil’s powder and liquid and the physical properties of the new sealer were tested according to ISO 6876:2012 and compared to those of Endofil alone. One‐way analysis of variance (ANOVA) followed by Tukey post hoc test was used to compare between more than two groups in non‐related samples. Results: All groups showed varying degrees of shrinkage with Group B having the lowest shrinkage and setting time, whereas Groups A and D experienced the highest shrinkage. All groups experienced solubility; Group B had the highest mass loss and Group D showed the lowest. Group A showed the lowest film thickness. Radiopacity of all groups satisfies the ISO recommendations for root canal sealers. Conclusion: Moringa added to ZnO/E sealer showed acceptable physical properties of the commercial Endofil sealer.
