Description

The persistent and secondary intraradicular infections are the primary causes of post-treatment disease following endodontic treatment of any tooth. When conventional root canal treatment fails, endodontic retreatment is often the preferred option, as it represents one of the most conservative approaches. Endodontic retreatment involves removing old root canal filling material followed by cleaning, shaping, and refilling the canals. It may be associated with postoperative pain due to periapical tissue irritation and apical extrusion of debris during instrumentation.

Interventions

  • Xp Finisher R file (Procedure)
    to evaluate the incidence and severity of postoperative pain using a numeric rating scale at 24, 48, and 72 hours and periapical healing via CBCT following retreatment with two different irrigation activation techniques: 1. Xp Finisher R file activation of irrigation. 2. Ultrasonic activation of irrigation.
