Nonsurgical retrieval of bioceramic materials using ultrasonics: a case report

Year: 2026

Type: article

Abstract: BACKGROUND: Endodontic retreatment requires removal of previous root canal filling materials, followed by biomechanical preparation and re-obturation. Bioceramic sealers pose a challenge owing to their strong adhesion to dentin and mineral deposition. While complete removal is difficult, adjunctive techniques such as ultrasonics may enhance retrieval. CASE PRESENTATION: A 22-year-old South Asian male presented with persistent symptoms after root canal therapy. Clinical and radiographic evaluation suggested failure associated with bioceramic sealer obturation. Retreatment was undertaken using rotary retreatment instruments, supplemented with ultrasonic activation and copious sodium hypochlorite irrigation. This approach facilitated substantial removal of the bioceramic material, allowing thorough cleaning and reshaping of the canal system prior to obturation. CONCLUSION: Although complete elimination of bioceramic sealers is challenging, their retrieval is achievable with the aid of ultrasonics and irrigants. This case demonstrates a successful endodontic retreatment strategy, emphasizing the clinical relevance of adjunctive techniques in managing previously obturated bioceramic materials.
