Abstract

Aim and objective: The aim of this study was to evaluate and compare the intra-orifice sealing ability of Cention N, packable bulk fill composite, and Zirconomer as an intra-orifice barrier in endodontically treated teeth under a stereomicroscope. Materials and methods: Thirty-three single-rooted teeth were decoronated at cementoenamel junction (CEJ). Following root canal treatment, 3 mm of the coronal gutta-percha was removed and the experimental material [group I (n = 11)—packable bulk fill composite, group II (n = 11)—Zirconomer, and group III (n = 11)—Cention N] was placed as an intra-orifice barrier. A dye penetration test was performed and observed under a stereomicroscope. The extent of dye penetration was measured and statistical analysis using analysis of variance (ANOVA) and post hoc Tukey test was done. Results: The mean values of microleakage (in mm) for groups I, II, and III were 1.18, 0.81, and 0.74, respectively. Tukey–Kramer multiple comparison test showed no significant difference between mean values of microleakage when groups I, II, and III were compared at 5% and 1% level of significance. Student's unpaired t-test showed a significant difference between mean values of microleakage between group I and group III as well as group I and group II. No significant differences were seen between group II and group III. Conclusion: Among all the groups checked, group III (Cention N) showed the highest sealing ability as an intra-orifice barrier. Clinical significance: Intra-orifice barrier acts as a double seal and minimizes the amount of microleakage coronally in root canal-treated teeth. Immediate placement of additional material in the orifices acts as a secondary line of defense along with temporary filling after obturation.
