What this Trial Is About
The goal of this randomized controlled clinical trial is to determine whether regenerative endodontic treatment can improve healing outcomes in teeth with apical periodontitis following failed root canal treatment. The study includes adult patients who require non-surgical root canal retreatment due to persistent periapical lesions. The main questions it aims to answer are: Does regenerative endodontic treatment improve periapical healing compared with conventional non-surgical root canal retreatment? Does regenerative treatment increase long-term treatment success and tooth survival? Researchers will compare conventional non-surgical root canal retreatment with regenerative endodontic treatment using injectable platelet-rich fibrin (i-PRF) to see if the regenerative approach results in better clinical and radiographic outcomes. Participants will: Be randomly assigned to receive either conventional retreatment or regenerative endodontic treatment. Undergo clinical and radiographic evaluations over a two-year follow-up period. Be assessed for pain, sensitivity, pulp vitality, hard tissue formation, and periapical healing.
