    Background: This study aims to assess the Effectiveness of different irrigation activation techniques in removing smear layer from the confines of root canal using SEM analysis. Subjects/Materials and Methods: A total samples of 80 maxillary first molars with a single straight palatal root canal were prepared to size X4 (protaper Next, Dentsply) and assigned to 2 groups (n=40): normal saline and EDTA 17%, each group subdivided into five subgroups (n=8): conventional needle irrigation (CN), EndoActivator (EA), ultrasonic activated irrigation (UAI), Er.Cr.YSGG 2780nm laser, and Diode 940nm laser. Roots were split longitudinally then each half were divided into three regions corresponding to the apical, middle, and coronal. Scanning electron microscope investigations were accomplished. Three pictures for each region were taken and scored. Presence of smear layer was assessed using (5-gra.. Read More»
