Objectives: To evaluate the effect of different irrigation activation techniques (IATs) on smear layer removal after post-space preparation. Methods: Forty single-rooted mandibular premolars with no root canal treatment were selected. Teeth were decoronated at 15 mm, and apical patency was confirmed using a #10 K-f...
