Quantitative Evaluation of Apically Extruded Debris of Root Canal Dentin Layer with WaveOne, ProTaper Next, ProTaper Gold Rotary File Systems

Endodontic flare-up or post-operative pain occurs when debris such as necrotic pulp tissue, dentin chips, irrigants, and microorganisms are extruded from the apical foramen intraoperatively into periradicular tissue during root canal instrumentation. This study compared amount of extrusion layer after using reciprocating rotary file systems (WaveOne, ProTaper Next Gold). Sixty extracted human maxillary central incisors with one closed apex were included in study. Samples randomly equally divided three groups (n = 20) according to used for preparation canal. Teeth WO group instrumented by WaveOne, while PTN Next, teeth samples PTG cleaned shaped Gold. The mean apically weight grams was estimated modified Myers Montgomery experimental model. Analysis variance (ANOVA) test comparison groups. Post hoc LSD applied pairwise weight. α value significance 0.05. had significantly lower than (p 0.001). revealed that there a statistically significant difference between (0.0215 vs. 0.0341, p 0.001); 0.0324, 0.003). Root preparations different associated layer. However, WaveOne system resulted comparatively Gold systems.
