Abstract

The present study was conducted to evaluate apical extrusion of debris by instrumentation with three commercially available rotary file systems. Materials & Methods: Forty eight freshly extracted maxillary lateral incisors were collected by systematic sampling procedure. All samples were sectioned to make access opening. The teeth were studied into three study groups with sixteen teeth each. Bio mechanical preparations were finished by three different commercially available rotary file systems (One Shape Rotary File System- group I, Neoendo Flex Files- group II, Waldent Wal-flex Gold Rotary Files- group III). Debris collection was done glass vial. The exact weight of the collected debris was calculated by subtracting the weight of the empty vials from the weight of the vials containing debris. P value less than 0.05 was considered significant. Statistical Analysis & Results: Statistical analysis was performed using statistical software ‘Statistical Package for the Social Sciences (SPSS)’ version 22. Mean debris extrusion by One Shape Rotary Files was 0.181 milligrams. Neoendo Flex Rotary Files showed 0.238 milligrams of mean extruded debris while Waldent Wal-flex Gold Rotary Files showed 0.292 milligrams of mean extruded debris. Level of Significance (p value) was significant for group III. The p value was very significant for ANOVA conducted between groups (0.001). Conclusion: In all the three tested systems, Waldent wal-flex gold rotary files confirmed maximum amount of debris extrusion. Minimum amount of debris was extruded by One shape rotary files. Hence, One shape rotary systems must be suggested for challenging cases.
