Mean ± SD (×1000) apical leakage of MTA and Biodentine (μL·cmH₂O⁻¹·min⁻¹) (n = 10).

	1 mm	2 mm	3 mm	4 mm
MTA	2.39 ± 0.14a	1.98 ± 0.17a	0.67 ± 0.05b	0.56 ± 0.05b
Biodentine	2.03 ± 0.11a	1.85 ± 0.10a	0.71 ± 0.04b	0.60 ± 0.05b

The superscript letters (a and b) indicate significant differences between the tested thicknesses of biomaterials by one-way ANOVA and post hoc Kolmogorov-Smirnov test (p < 0.05).
