STERILE, CARIES
Single-visit pulpectomy was performed under strict aseptic conditions by a single operator. A perioperative evaluation was done using a digital intraoral photo-simulated phosphorus plate sensor (PSP, Planmeca ProSensor HD, Helsinki, Finland) before starting pulpectomy treatment. The teeth were anesthetized with 2% mepivacaine with 1:20,000 levonordefrin (Alexandria Co., Egypt) and isolated using a rubber dam (Midwest Dental, Texas, USA). Firstly, caries had been removed with sterile no.330 round-carbide burs (Mani Inc., Japan) in a high-speed contra-angle handpiece (NSK, Tokyo, Japan) under copious water cooling and high suction. After gaining the access opening & removing the pulp chamber’s roof, an apex locator (J. Morita MFG Corp., Kyoto, Japan) was used to assess the working length, then affirmed by a periapical radiograph. The working length was determined as one millimeter less than the apex.The mechanical instrumentation was done using the tested files according to each group. In group-I (Lastly, a post-operative CBCT image (KaVo OP 3D Vision, Kavo Dental, Biberach, Germany) was taken after completing the procedure using quick scan
