Abstract

This study compared the percentage reduction of total obturation materials, gutta‐percha and sealer, using two rotary file systems with/without solvent in retreating C‐shaped root canals and to evaluate the effect of the solvent on instrument separation. C‐shaped root canals were scanned using micro‐CT to identify the root canal morphology and randomly assigned to four groups (n = 12). Retreatment was performed using ProTaper Universal Retreatment (PTUR) or XP‐endo systems with/without solvent. The number of separated instruments were recorded. The samples were scanned pre‐ and post‐retreatment. The percentage reduction of total obturation materials, gutta‐percha and sealer, were calculated. The percentage reduction of gutta‐percha in the PTUR without solvent group was significantly lower than the other groups (P = 0.018). The number of separated instruments in the solvent groups were significantly lower than the no solvent groups (P < 0.05). Solvent increased gutta‐percha removal, when using PTUR and decreased the occurrence of separated instruments for both systems. [ABSTRACT FROM AUTHOR]
