Evaluation of the Efficacy of EASYDO ACTIVATOR Irrigation Technique in Intracanal Smear Layer and Debris Removal from Mature Permanent Teeth
Abstract
\n EASYDO ACTIVATOR (EA) is a continuously vibrational device for root canals irrigation, but its cleaning effectiveness has not been evaluated by any published reports. We were aiming to evaluate whether EA results in a greater intracanal smear layer and debris removal than conventional needle irrigation (NI) and passive ultrasonic irrigation (PUI). Twenty-seven single-rooted teeth were used. Canals were sized to R30 and irrigated with 3% sodium hypochlorite. Species were divided into three groups: Group 1: NI; Group 2: PUI; Group 3: EA. Canal walls were subjected to scanning electron microscopy. NI- and PUI-group canal cleanliness decreased from the coronal to apical direction (P\u2009<\u20090.05), except for EA group in the apical third. PUI removed more smear layer from the coronal and middle thirds than EA and NI (P\u2009<\u20090.05). PUI and EA were superior to NI regarding debris removal (P\u2009<\u20090.05). The smear layer and debris from the coronal and middle thirds were effectively removed with EA and PUI. More effective removal occurred from the apical third for EA compared with PUI (P\u2009<\u20090.05). Both methods removed smear layer and debris better than NI, providing a theoretical basis for the clinical application of EA.
