“…Removal of obturation material can be effected with endodontic hand files, heat-carrying or ultrasonic instruments, or engine driven rotary files (10). Several techniques using manual or rotary protocols with or without solvents have also been suggested to remove the filling material from root canals (1,16). However, there are no studies testing the influence of the age of the filling material on the capacity for filler removal.…”

The aim of this study was to evaluate the effectiveness of manual and rotary instrumentation techniques for removing root fillings after different storage times. Twenty-four canals from palatal roots of human maxillary molars were instrumented and filled with gutta-percha and zinc-oxide eugenol-based sealer (Endofill) , and were stored in saline for 6 years. Non-aged control specimens were treated in the same manner and stored for 1 week. All canals were retreated using hand files or ProTaper Universal NiTi rotary system. Radiographs were taken to determine the amount of remaining material in the canals. The roots were vertically split, the halves were examined with a clinical microscope and the obtained images were digitized. The images were evaluated with AutoCAD software and the percentage of residual material was calculated. Data were analyzed with two-way ANOVA and Tukey's test at 5% significance level. There was no statistically significant differences (p>0.05) between the manual and rotary techniques for filling material removal regardless the ageing effect on endodontic sealers. When only the age of the filling material was analyzed microscopically, non-aged fillings that remained on the middle third of the canals presented a higher percentage of material remaining (p<0.05) compared to the aged sealers and to the other thirds of the roots. The apical third showed a higher percentage of residual filling material in both radiographic and microscopic analysis when compared to the other root thirds. In conclusion, all canals presented residual filling material after endodontic retreatment procedures. Microscopic analysis was more effective than radiographs for detection of residual filling material.

“…An operating microscope (OPMI Pico; Carl Zeiss, Germany) at 10x magnification was used to evaluate the amount of remaining root filling material as used in the study of Kfir et al 32 A scoring system that was defined by Kosti et al 33 was used to assess the quantity of the remaining root canal filling materials on the canal walls; Score 0: no gutta-percha and no sealer, Score 1: debris of sealer, Score 2: debris of sealer and gutta-percha, Score 3: severe debris of sealer and guttapercha.…”

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.

“…154,155 The vast majority of studies have compared Resilon/Epihany to guttapercha and epoxy resin cement, however, this may prevent accurate extrapolation to other gutta-percha sealers as epoxy resins are associated with a higher level of residual debris than other cements. 156 Chloroform has been recommended by the manufacturers as an aid in removal of Resilon (RealSeal/Epiphany instructions, SybronEndo 2010). However, resin sealers are not dissolved by chloroform and it has an adverse effect on bond strength of Resilon/Epiphany when reobturating.…”
