Abstract
Twentyfour extracted human mandibular premolars with ovalshaped canals were assigned in two equal groups Following coronal cavity preparation a glide path was created Group A was subjected to canal preparation using a WaveOne primary file which was used along with syringe and needle irrigation and 10 mL of 24 NaOCl solution followed by flushing with 10 mL of 17 EDTA solution activation with EndoActivator for 1 min and final flushing with 10 mL of 24 NaOCl solution and activation for 30 s Group B the SAF system was used with continuous simultaneous irrigation provided by the system’s pump The irrigant was supplied at 5 mL/min alternating every minute between 24 NaOCl solution and 17 EDTA solution over a total of 4 min followed by final flushing with 10 mL of 24 NaOCl solution Extruded apical debris from each root canal was collected into a preweighed glass vial and dried The mean weight of the debris from each group was assessed and analyzed statistically Both systems resulted in apical debris extrusionThe results of the present ex vivo comparative study cannot be directly applied to the clinical situation Difference between both groups remains completely unclear maybe the amount of extrusion is harmless in both groups or similarly deleterious for the periradicular tissues in both groups or may be doserelated to the amount of the extruded material
