No results posted yet for this study

Summary

This prospective clinical study evaluated whether maintaining apical patency during single-visit root canal treatment influences postoperative pain in adults with single-rooted maxillary anterior teeth and chronic apical periodontitis. Participants were systematically allocated in consecutive order to treatment with apical patency or treatment without apical patency. The study also evaluated the relationship between baseline periapical lesion volume measured on clinically indicated cone-beam computed tomography images and postoperative pain.

Conditions

  • Apical Periodontitis

Interventions

PROCEDURE

Apical Patency During Root Canal Treatment

A #10 stainless-steel K-file was passively advanced approximately 0.5-1 mm beyond the working length after each rotary instrument during standardized single-visit root canal treatment.

PROCEDURE

Root Canal Treatment Without Apical Patency

Standardized single-visit root canal treatment was performed with instrumentation confined to the working length and without intentional passage of an instrument beyond the apical foramen.
