Retrograde Treatment With Bioceramic Sealers: A Case Report.

Area of Science:

• Endodontics
• Dental Materials Science
• Oral Surgery

Background:

• Maxillary canines are critical for occlusion and aesthetics.
• Complex root canal anatomy and periapical lesions pose treatment challenges.
• Traditional post removal risks root fracture, potentially leading to tooth loss.

Purpose of the Study:

• To evaluate the efficacy of retrograde bioceramic sealer application in a maxillary canine with complex anatomy and a periapical lesion.
• To explore conservative alternatives to orthograde endodontic retreatment when post removal is high-risk.

Main Methods:

• Cone-beam computed tomography (CBCT) for diagnosis.
• Retrograde endodontic treatment using a bioceramic sealer.
• Clinical and radiographic assessment of periapical healing.

Main Results:

• Successful and predictable sealing of the root apex was achieved.
• Favorable periapical healing was observed radiographically.
• The tooth was preserved, maintaining its function in the prosthodontic bridge.

Conclusions:

• Retrograde bioceramic sealer application is an effective alternative for managing complex endodontic cases with periapical lesions.
• This technique offers a conservative approach to preserve teeth at risk of fracture during retreatment.
• Bioceramic materials demonstrate promise as reliable retro-filling agents in specific endodontic scenarios.
