Evaluation of apically extruded debris during root canal retreatment with several NiTi systems

Abstract

Use of the reciprocating single file system resulted in the extrusion of significantly less debris compared with the full-sequence rotary NiTi instruments and hand filing. Use of the ProTaper and Reciproc instruments required less time for retreatment procedures than use of the Mtwo or H-file.

Efficiency and apical extrusion of debris: a comparative ex vivo study of four retreatment techniques in severely curved root canals

“…Reciproc caused significantly less extruded debris than H‐files, but no significant differences were observed between R‐Endo, PTU‐R and H‐file systems, as reported in previous studies (Dinçer et al . , Topçuoğlu et al . ).…”

Apically extruded debris in filling removal of curved canals using 3 NiTi systems and hand files

“…However, it is known that filling removal can lead to extrusion of debris and cause periapical inflammation, flare-ups or failure of apical healing (5). Different amounts of extruded debris have been reported, depending on the instrumentation technique and the design of instruments (5)(6)(7)(8)(9)(10)(11)(12).…”

“…To date, some studies have evaluated apical debris extrusion when a single-file reciprocating system was used for filling removal (8,(10)(11)(12)18,20,21). However, few studies have evaluated the debris extrusion during endodontic retreatment in curved canals (11), and there are no studies regarding the performance of WOG in filling removal, neither in debris extrusion during filling removal of well-filled curved canals.…”

Effect of solvents on apically extruded debris and irrigant during root canal retreatment using reciprocating instruments

“…, Dincer et al . ). A previous study also evaluated the effect of solvents during root filling removal and reported the use of a solvent specific to the sealer reduced apical extrusion (Çanakçi et al .…”
