“…10,13,16 However, while gutta-percha can be removed without great difficulty with the use of organic solvents combined with endodontic instruments, the endodontic sealer can resist dissolution and complete removal might not be achieved. 17,18 These results were confirmed by SEM; the intraradicular dentin was observed to be covered by filling remnants when PTR was used without a solvent, whereas sealer-free areas with open tubules could be observed on intraradicular dentin surfaces when solvents were applied.…”

Influence of solvents on the bond strength of resin sealer to intraradicular dentin after retreatment Abstract: This study evaluated the removal of filling material with ProTaper Universal Rotary Retreatment system (PTR) combined with solvents and the influence of solvents on the bond strength (PBS) of sealer to intraradicular dentin after canal reobturation. Roots were endodontically treated and distributed to five groups (n = 12). The control group was not retreated. In the four experimental groups, canals were retreated with PTR alone or in combination with xylol, orange oil, and eucalyptol. After filling material removal, two specimens of each group were analysed by SEM and µCT to verify the presence of filling remnants on root canal walls. The other roots were reobturated and sectioned in 1-mm-thick dentin slices that were subjected to the push-out test. Data were analysed by two-way ANOVA and Tukey's test (α = 0.05). SEM and µCT analysis revealed that all retreatment techniques left filling remnants on canal walls. The control group (3.47 ± 1.21) presented significantly higher (p < 0.05) PBS than the experimental groups. The groups retreated with PTR alone (2.59 ± 0.99) or combined with xylol (2.54 ± 0.77) and orange oil (2.32 ± 0.93) presented similar bond strength (p > 0.05), and differed significantly from the group with eucalyptol (1.89 ± 0.63). The solvents reduced the PBS of the sealer to dentin and no retreatment technique promoted complete removal of filling material.

Introduction: The removal of the filling material during the Endodontic retreatment is essential, so a better action of solvents on the gutta-percha is desired. Objective: To evaluate in vitro the gutta-percha dissolution ability of different solvents. Material and methods: Four solvents (xylol, eucalyptol, citrol, and orange oil) were applied on gutta-percha points, which had been later submitted to the weight loss analysis at 2, 5, and 10 minutes. For each solvent, 30 size #60 main cones were used, divided into three groups. Distilled water was used as control group. The statistical test applied was Kruskal-Wallis. Results: No statistically significant difference occurred among the solvents at 2 minutes (p > 0.05); however, during this period, citrol had the best performance. In longer time intervals, the xylol showed differences compared to eucalyptol at 5 minutes and to eucalyptol and citrol at 10 minutes (p < 0.05). The worst results were found for eucalyptol. Conclusion: This xylol was the solvent with improved ability to dissolve the gutta-percha points, with better results at longer time periods.
