| Summary: | Purpose: The aim of this study was to evaluate
the amount of apically extruded debris during
endodontic retreatment with different file systems.
Materials and Methods: Sixty extracted human
mandibular premolar teeth were used in this study.
Root canals of the teeth were instrumented and filled
before being randomly assigned to three groups. Guttapercha
was removed using the Reciproc system, the
Twisted File system (TF), and Hedström-files (H-file).
Apically extruded debris was collected and dried in
pre-weighed Eppendorf tubes. The amount of extruded
debris was assessed with an electronic balance.
Data were statistically analyzed using one-way
ANOVA, Kruskal-Wallis, and Mann-Whitney U tests.
Results: The Reciproc and TF systems extruded
significantly less debris than the H-file
(p<0.05). However, no significant difference was
found between the Reciproc and TF systems.
Conclusion: All tested file systems caused
apical extrusion of debris. Both the rotary
file (TF) and the reciprocating single-file
(Reciproc) systems were associated with less
apical extrusion compared with the H-file. |
