Abstract | ||||
Aim: The aim of this study was to compare the amount of apically extruded debris of (SAF) versus (FAFFF) during mechanical preparation of mandibular premolars. Methodology: Forty-eight extracted human mandibular premolars with single canals and standardized lengths were instrumented using FAFFF 20 taper 4%. Then samples were randomly divided into 4 groups (n=12 teeth) as follow: Group (A) Root canals were prepared by SAF (1.5mm) file, Group (B) Root canals were prepared by SAF size (1.5mm) file, followed by SAF size (2.0mm), Group (C) Root canals were prepared by (FAFFF) 25 taper 6%, followed by (FAFFF) 35 taper 4% and Group (D) Root canals were prepared by (FAFFF) 25 taper 6%. Debris extruded during instrumentation were collected into pre-weighed Eppendorf tubes. The Eppendorf tubes were then stored in an incubator at 37ºC for 15 days for complete dehydration of extruded debris. Each Eppendorf tube with extruded debris was then weighed three consecutive times to obtain the final weight. Then the average weight of extruded debris was calculated. Results: Group B (SAF 2.0mm) showed Statistically the highest mean and standard deviation of extruded debris when compared to the other three groups. While, there was no statistically significant difference between group A, C and D. Conclusion: Under the conditions of this study, all systems caused apical debris extrusion. SAF (2mm) instrumentation was associated with the highest amount of debris extrusion compared to the other groups. | ||||
