Background: Zinc oxide–eugenol is the most commonly used sealer. However, it has irritating and cytotoxic effects. Therefore, research in this field was being carried out to develop newer root canal sealers. Aloe vera gel is known for its medicinal properties. Thus, an attempt has been made to replace eugenol with Aloe vera. Aims: To compare the sealing ability of zinc oxide–eugenol and zinc oxide–Aloe vera, as a root canal sealer by in vitro scanning electron microscopy (SEM) analysis. Materials and Methods: Thirty freshly extracted single-rooted anterior teeth were selected and randomly divided into two equal groups. Access cavities were prepared, and canals were irrigated and instrumented followed by obturated with a zinc oxide–eugenol sealer and gutta-percha for Group I, whereas for Group II, zinc oxide–Aloe vera sealer was used with gutta-percha. The teeth were longitudinally split into two halves and subjected to SEM analysis to assess interface between obturating material and dentin. Statistical Analysis: Data obtained were analyzed by Student's t-test. Results and Conclusions: Zinc oxide–Aloe vera showed significantly better sealability as compared to zinc oxide–eugenol sealer (P ≤ 0.05). The analyzed data revealed that zinc oxide–Aloe vera as a root canal sealer is a better alternative to zinc oxide–eugenol.
