| Popis: | Context: Residual filling material can impair the prognosis in endodontic retreatment cases. A variety of file systems have been used in both rotary and reciprocating motion. Aims: To evaluate and compare the ability of ProTaper Universal Retreatment systems, GPR Mani Retreatment systems and, V Blue Reciproc systems in removal of gutta percha and bioceramicsealer from oval root canals using micro-computed tomography. Materials and Methods: Sixty extracted human mandibular premolar with oval canals standardised with cone beam computed tomography(CBCT). Following preparation with ProTaper Next files and obturation with gutta-percha and I Root SP sealer all specimens were randomly assigned to three groups ProTaper Universal retreatment system (PTUR), GPR Mani Retreatment system and V-Blue files, (n=20). Quality of obturation was confirmed with CBCT. After 1 month, retreatment was carried out and the percentage of remaining obturating material was evaluated before and after retreatment through micro-CT imaging. Two sample means and Kolmogorov-Smirnov test were used to analyse data. Results: The V-Blue files removed 97.27% of residual filling material whereas PTUR and GPR Maniremoved 85% and 79.33% respectivelyand the difference between V-Blue and other two files tested was statistically significant (P< 0.05). |
