Summary

This randomized controlled trial will investigate if maintaining apical patency-a technique where a small file is gently moved past the root's end during cleaning-affects pain after a root canal. The study will include 48 adult patients needing root canal treatment on a back molar tooth with a dead nerve and infection at the root tip. Participants will be randomly assigned to one of two groups: one where the apical patency technique is used, and one where it is not. All other treatment steps will be identical. Patients will record their pain levels on a standard scale (0-100 mm Visual Analog Scale) at 6, 12, 24, 48, and 72 hours after the procedure. The goal is to determine if this specific technique influences the intensity and duration of post-treatment pain

Conditions

  • Periapical Periodontitis
  • Dental Pulp Necrosis

Interventions

PROCEDURE

Patency Group

The procedural technique of passively advancing a small endodontic file (size #10 K-file) 1 mm beyond the apical foramen before and after each larger instrument during root canal cleaning and shaping. This is done to prevent blockage of the apical portion of the canal.

PROCEDURE

Standard Root Canal Instrumentation

Root canal instrumentation that is strictly confined to the canal space, terminating at the apical constriction (working length) and avoiding any instrumentation beyond the apical foramen.
