چکیده    Background. this study investigated the effects of solvent use and initial canal enlargement size on apically extruded debris (aed). methods. the palatal roots of 60 upper molars were assigned to two groups based on the initial preparation size: f3 or f4 protaper universal files. the roots were obturated using the single-cone technique. each group was subdivided based on the retreatment procedures: with or without solvent. after evaporation, the eppendorf tubes were weighed using an electronic balance. the data were statistically analyzed (p=0.05). results. using a solvent enhanced the amount of aed in samples initially prepared up to f3 or f4 files (p<0.05). when the solvent was used, the aed was greater in samples initially prepared up to the f4 file (p<0.05); however, when the solvent was omitted, the results were reversed (p<0.05). conclusion. both parameters had a role in aed. solvents should be used cautiously during root canal retreatment because of the potential for apical extrusion of filling materials. using files with smaller tapers during initial preparation might be beneficial when considering the amount of aed compared to those with larger tapers.
