NCT07808684

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Treatment of Postoperative Pain

    Pain scores will be recorded on Visual Analog Scale (VAS) using a 0 to 10 pain score basis with 0 being no pain and 10 being the worst pain. Recording will be done everyday for 7 days period.

    from 0 hours to 1 week after the procedure

Study Arms (2)

one curve file

ACTIVE COMPARATOR

About 15 cases will be subjected to one single file to the full working length. File will be operated at 300 rpm/2.5 Ncm torque in continuous rotation

Procedure: AF One single-file rotary system

AF Fanta flat sided file system

ACTIVE COMPARATOR

About 15 cases will be subjected to one single file to the full working length.File will be operated at 300 rpm/2.5 Ncm torque in continuous rotation

Procedure: AF One single-file rotary system

Interventions

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.

Also known as: One Curve rotary system
