    Aim: The first step in the retreatment of failed endodontically treated teeth is the removal of obturation materials from the root canals system. This study aimed to assess the effectiveness of two ultrasonic irrigation techniques using two different file systems in non-surgical endodontics retreatment. Materials and methods: Forty eight extracted maxillary first molars palatal roots were prepared using size X3 (protaper next, dentsply) and obturated using a single cone technique using a bioceramic sealer. After two weeks of storage at 37°C and 100% humidity, the teeth were randomly divided into two groups (n=24) based on the type of instrument used for retreatment: Reciproc (R25) and Wave One Gold (WOG), then each group was subdivided according to the irrigation technique used: Conventional Needle Irrigation (CNI), Passive Ultrasonic Ir..
