Description

Endodontic treatment aims to achieve optimal biological outcomes while minimizing patient's discomfort during and after the procedure. Postoperative pain remains a common complication and is considered a multifactorial phenomenon influenced by several factors, including preoperative pain, age, gender, systemic health, presence of apical periodontitis, instrumentation technique, type and design of endodontic instruments, and the use of intracanal medications.

Interventions

  • AF One single-file rotary system (Procedure)
    to evaluate and compare the amount of apically extruded debris using the AF One single-file rotary system, featuring a flat-sided design, and the One Curve rotary system in curved mesiobuccal canals of mandibular first molars. Additionally, this study aims to assess postoperative pain associated with both systems and to investigate the potential correlation between apical debris extrusion and postoperative pain.

Eligibility criteria

Inclusion Criteria: * Teeth with mature apex * Straight root canal or mild curvature not exceeding(5-10) Schneider. * Has intact crown ( coronal structure) * Presence of one orifices and one apices, patency achieved by a #10-15 K-file to the apical foramen Exclusion Criteria: * Previous root canal treatment. * Internal/external resorption. * Immature root apices. * Caries/cracks/fractures on the root surface. * Root canal curvature more than 10 degrees. * Teeth in which the apical minor constriction was gauged larger than a size 20 hand file.
