ABSTRACT

Background and Aim Almost all endodontic treatment instruments used for cleaning and shaping are known to cause some amount of apically extruded debris (AED), which can cause post-operative complications known as flare-ups. Therefore the aim of this in- vitro study was to assess the AED during root canal preparation using rotary and reciprocating instrumentation systems. Material and Methodology In this study, 15 human mandibular first premolars were randomly assigned into 3 groups (n=5). The root canals were instrumented using full sequence rotary K3 XF files and Hyflex CM files and reciprocating single file system WaveOne Gold reciprocating files. Distilled water was used as an irrigant. The extruded debris was collected in preweighed Eppendorf tubes and assessed with an electronic balance and compared. The debris extrusion was compared and statistically analyzed using one-way ANOVA and post hoc test. Results Wave One Gold reciprocating files showed significantly more debris extrusion compared to Hyflex CM and K3 XF rotary file system. Conclusions Under the condition of the present study, it was shown that all the instrumentation techniques resulted in apically extruded debris. However, reciprocating WaveOne Gold file system showed more apically extruded debris compared to full sequence rotary Hyflex CM and K3 XF.
