Abstract
The introduction of bioceramic sealer has
enabled the development of properties such as biocompatibility, bioactivity,
and sealing ability, due to the interaction between the sealer and radicular
dentin, which results in the formation of hydroxyapatite as a byproduct.
Therefore, the ability of the cement to penetrate dentinal tubules is a key
factor to consider during retreatment, along with the need for effective
retreatment strategies to adequately address these clinical challenges. This
study aims to evaluate the efficacy of two different cleaning and irrigant
activation techniques (XP-Endo Finisher and AF Max 1) for the removal of the
bioceramic cement Neosealer flo (ZARC) during root canal retreatment, analyzed
using scanning electron microscopy (SEM). Materials and method: an in vitro
study was conducted using 25 single-rooted premolar roots. After disinfection,
instrumentation was performed with RECIPROC BLUE 25 files, and obturation was
carried out using the hydraulic technique with a single cone and NeoSealer Flo
(ZARC) bioceramic cement. After three weeks, retreatment was performed using AF
Retreatment Rotary files (FANTA, Shanghai, China), and specimens were randomly
divided into two groups of 12 roots and one group of a single root. Group 1
(Negative control): no complementary system used, group 2: XP-Endo Finisher
used, group 3: AF Max 1 used. The specimens were examined by thirds using SEM.
Statistical analysis was performed in RStudio using the Kruskal–Wallis and
Mann–Whitney tests. Results: Kruskal–Wallis test (C vs XP vs AF) by canal
third: cervical: H = 5.882, p = 0.053, ε² = 0.176, middle: H = 3.710, p = 0.156, ε² = 0.078, apical: H = 0.474, p = 0.789, ε² ≈ 0, Mann–Whitney comparisons (XP vs AF) by third: cervical: p =
0.080, middle: p = 0.218 (XP tends to perform better), apical: p = 0.799. No
statistically significant differences were detected between techniques by canal
third; however, a trend favoring XP was observed in the cervical third.
Conclusion: complementary cleaning techniques enhanced the removal of
bioceramic cement. Nevertheless, none of the techniques completely eliminated
the residual filling material from the root canal.
