Aim: To evaluate the sealing ability of different types of calcium silicate-based cement (CSC) when used as retrograde filling materials. Materials and methods: A total of 85 extracted single-rooted teeth were decoronated, instrumented, and obturated. A 3 mm root end resection was performed, followed by a 3 mm retrograde cavity preparation. Teeth were randomly divided into five equal groups (n = 15) according to the retro-filling material applied; group I, ProRoot mineral trioxide aggregate; group II, Biodentine; group III, NeoPutty MTA; group IV, Produits Dentaires (PD) MTA White; group V, TheraCal LC, in addition to positive and negative controls. After 24 hours, the roots were covered with nail polish and immersed in methylene blue dye for 24 hours. After longitudinal sectioning using a diamond disk, roots were examined using a stereomicroscope at 8× magnification for dye penetration, and maximum linear dye penetration was measured in millimeters using ZEN 3.4 software. Statistical analysis was performed using a one-way analysis of variance (ANOVA) test followed by Tukey's post hoc test. Results: All tested retro-filling materials showed dye penetration and failed to totally seal the root end. ProRoot MTA and Biodentine showed the least dye penetration, followed by NeoPutty and PD MTA White with a statistically significant difference. TheraCal LC showed maximum dye penetration with a statistically significant difference. Conclusion: Altering the consistency and manipulation of different CSC significantly affects their sealing ability. Clinical significance: Proper sealing of the retrograde cavities is mandatory. ProRoot MTA and Biodentine provided a better sealing ability for retrograde cavities.
