“…Therefore, three different solvents were used; Resosolv was chosen because of the resin ingredient of MTA Fillapex; Guttasolv was chosen for its common usage, and Endosolv E consists of tetrachloroethlyne and is effective on both gutta percha and sealer components. 40 Hess et al 36 reported that conventional He et al 24 reported that Resosolv is an effective solvent for retreatment in root canals obturated with resin based sealer and gutta percha. The Resosolv solvent could be effective on such resin ingredient of MTA Fillapex like salicylate resin, diluting resins, natural resin, nanoparticulated resin.…”

Aim:The aim of this study was to evaluate the efficiencies of different conventional solvents on the removal of root fillings performed with MTA Fillapex root canal sealer and gutta-percha. Material and Method: Forty-five maxillary central incisors human teeth were included. Sample lengths were adjusted to 16 mm and root canal preparations were performed with K3 instruments up to 30/.04 size. MTA Fillapex® root canal sealer and gutta percha were used to obturate the canals with cold lateral condensation technique. The teeth were stored for 1 week at 37 ºC in 100% relative humidity. Specimens were randomly assigned into three groups (n:15): G1: Resosolv, G2: Endosolv E and G3: Guttasolv. 35/.04 K3 instruments were used as the final retreatment instruments. Final irrigation was performed and root canals were dried. The teeth were split along their long axis and operating microscope at 10x magnification was used to evaluate the amount of remaining root filling material. Samples were then scored. SEM and EDS analysis were used to enhance the accuracy of evaluations. Data were subjected to statistical interpretation using Kruskal-Wallis test at a 95% confidence level (p<0.05). Results: There were no statistically significant differences among the three experimental groups in the apical, middle and coronal thirds of the root canals (p>0.05). Intra group comparisons showed that apical, middle and coronal thirds of each group showed no significant differences among themselves (p>0.05). Conclusion: Root fillings performed with MTA Fillapex® and gutta percha could be retreated with the solvents used in the study.

“…14,15 This situation occurs in previously obturated canals by single cone tecnhique. 16 So, there is possible relation between the chemical nature of the employed solvent and the retreatment rotary instruments with the root canal obturation technique that was previously performed. However, there are no studies evaluating the effects of xylol or Endosolv-R solvents associated with retreatment rotary instrument in root canals previously obturated by lateral compaction or single cone technique.…”

Objective: To quantify the persistence of residues after endo dontic retreatment related to the root canal obturation technique (lateral compaction or single cone) previously performed and the solvent used (xylol or EndosolvR) in the cervical and root apical segment using digital radiograph. Materials and methods:Forty root canals were prepared using the F2 instrument and filled with gutta-percha and AH Plus, 20 canals using #25 point by lateral compaction and the other 20 using F2 point by single cone. The root canals were transversely sectioned, and two segments (cervical and apical) were obtained. Radiographs were taken from the segment in buccolingual and mesiodistal direction, as well as the area that was originally filled with the root canal obturation was measured using ImageJ. After the specimens were set on special devices, the obturations were removed using the rotary system and divided into four groups (n = 10): G1 -lateral compaction and xylol; G2 -lateral compaction and EndosolvR; G3 -single cone and xylol; and G4 -single cone and Endosolv-R. A new radiograph was taken and the area occupied by residues was measured. The persistence of residues was obtained from the obturation remaining in the root canal in percentage. The data were analyzed using Kruskal-Wallis test (p = 0.05).Results: There was no difference among the examined groups, regardless of the radicular segment or the radiograph direction (p > 0.05). Conclusion:The endodontic retreatment using xylol or EndosolvR in the obturations previously performed by lateral compaction or single cone technique presented similar persis tence of residues in the root canal, regardless of the radicular segment.
