Özet
Background: To evaluate the efficiency of two stage retreatmentmethod in which the Self--Adjusting File (SAF) is used after R-Endoretreatment files to remove root canal filling residual in vitro.Methods: Sixteen maxillary premolars with single, oval-shaped rootcanal were instrumented up to size 45 and the canals were filled.Bucco-palatinal and mesio--distal radiographs were taken after rootfilling and each stage of the retreatment procedure. Stage consistedof R-Endo retreatment files, which were used to remove the bulk ofroot filling, followed by stage in which SAF file was applied toremove the remnants. Using an image analysis software, the amountof radiopaque residue was compared on digital radiographs.Results: ln the mesio-distal projection, radiopaque residue waspresent after using the R-Endo retreatment files in 8.78 (:5)%,8.22 (:9.43)% and 16.78 (:24.36)% of the coronal, middle andapical thirds, respectively. Additional use of the SAF reduced thesepercents to 5.13 (:4.36)%, 4.22 (:8.68)% and 7.97 (:22.18)%(p
