Different Kinematics Within a Single-File System and Postoperative Pain

The goal of this clinical trial is to evaluating the influence of single file rotary system for root canal instrumentation using different kinematics on postoperative pain, the primary purpose: measuring post-operative pain by Numerical rating scale in a cohort population treatyed in Jordan Universoit of science and technology post graduate clinics with previously intittaed root canal treatement and could include any of the following: sex/gender, age groups (18-65 ), and healthy volunteers. The main questions it aims to answer \[is/are: * Is there any difference in postoperative pain after root canal treatment with different kinamtics * Is this correlated with the level of cytokines measured taken from inside the canal system before and after treament whioch will be analyzed by the ELISA Kit for pain biomarkers. * Is this related to in vitro debris extrusion, and can it validate previous research with the same methodology for debris extrusion measurement Researchers will compare 5 groups, which are Canal pro jeni, Continuous clockwise rotation (CCR), Optimum Torque Reverse (OTR), Forward reciprocating motion (REC), and Twisted Adaptive motion (TFA). All motions will be used with the One Curve file system Participants will report the level of pain after traatment level of cytokines will be measured by taking samples from the periapical area before, during, and after trematemtn
