Overview

Case reports document intraradicular sealer reduction in root canal retreatment, suggesting uncertain clinical outcomes.

Key Points

  • This research aims to document the radiographic reduction of a calcium silicate-based sealer during root canal retreatment.
  • Four cases were evaluated after nonsurgical root canal retreatment using a premixed calcium silicate-based sealer.
  • Follow-up included periapical radiographs and cone-beam computed tomography at 7–24 months post-treatment.
  • Outcome assessment relied on qualitative clinical and radiographic criteria without volumetric analysis.
  • Partial sealer reduction was observed in all cases during follow-up evaluations.
  • Two cases showed signs of periapical healing and remained symptom-free; the other two had persistent or recurrent issues despite sealer reduction.
  • The findings indicate that sealer reduction does not consistently correlate with positive clinical outcomes.
