Background: It is difficult to identify a potential sealant with penetration depth until practically analyzed. A scanning electron microscopy (SEM) overview could better describe the internal picture of the materials sealed to the tooth surface on in vitro experimentation since it being a vital procedure for successful obturation. Hence, this study was undertaken to compare the penetration depth of three root canal sealers most commonly available viz., AH Plus® (Dentsply, New Delhi, India), Tubli- Seal™ (Kerr Dental, New Delhi, India), and Apexit® Plus (Ivoclar Vivadent, New Delhi, India) with different compositions using SEM.
Materials and Methods: A total of 30 single-rooted mandibular premolars decoronated and the canal preparation done by step back technique was used for this study. 17% of ethylenediaminetetraacetic acid (EDTA) used as final flush. Prepared specimens were divided into three groups of 10 teeth each, and different sealers were used for each group (zinc oxide eugenol-based - Tubli-Seal™, calcium hydroxide-based - Apexit® Plus, and resin-based sealer - AH Plus®). After obturation, teeth were split longitudinally and viewed under SEM.
Results: There was no statistically significant difference among the means of measured depth of penetration of AH Plus® and Apexit® Plus sealer. However, Tubli-Seal™ values projected statistically significant differences in comparison to AH Plus® and Apexit® Plus sealer. Means of measured depth of penetration of different sealers were subjected to one-way ANOVA and Duncan's multiple range test with a statistical significance at < 0.001.
Conclusion: Zinc oxide eugenol-based sealer (Tubli-Seal™) shows less depth of penetration as compared to the calcium hydroxide-based sealer (Apexit® Plus) and resin-based sealer (AH Plus®). |
