T1: at 15 min after root-end filling, T2: at 24 h, T3: at 7 days, T4: at 14 days, T5 at 30 days.

Different upper-case letters in the same column indicated statistically significant differences among materials (p < 0.05). Different lower-case letter in the same row indicated statistically significant differences between immersion periods (p < 0.05).
