Özet
Abstract: Background: To evaluate the efficiency of two stage retreatment method in which the Self--Adjusting File (SAF) is used after R-Endo retreatment files to remove root canal filling residual in vitro. Methods: Sixteen maxillary premolars with single, oval-shaped root canal were instrumented up to size 45 and the canals were filled. Bucco-palatinal and mesio--distal radiographs were taken after root filling and each stage of the retreatment procedure. Stage consisted of R-Endo retreatment files, which were used to remove the bulk of root filling, followed by stage in which SAF file was applied to remove the remnants. Using an image analysis software, the amount of radiopaque residue was compared on digital radiographs. Results: ln the mesio-distal projection, radiopaque residue was present after using the R-Endo retreatment files in 8.78 (: 5)%, 8.22 (: 9.43)% and 16.78 (: 24.36)% of the coronal, middle and apical thirds, respectively. Additional use of the SAF reduced these percents to 5.13 (: 4.36)%, 4.22 (: 8.68)% and 7.97 (: 22.18)% (p<0.05). ln the bucco--palatinal projection, radiopaque residue was present after using the R-Endo files in 16.70 (: 13.51)%, 10.23 (: 10.46)% and 28.49 (: 35.44)% of the coronal, middle and apical thirds, respectively. Additional use of the SAF reduced these percents to 13.31 (: 13.71)%, 5.24 (: 10.87)% and 15.9 (: 31.58)% (p<0.05 for the middle and the apical third; p>0.05 for the coronal third). Conclusion: No system removed the root filling materials completely. Applying the SAF after R-Endo retreatment files resulted in significance reduction in the amount of filling residue in oval canals.
