Summary
Calcium silicate-based materials used in endodontics can extrude into periapical tissues, potentially hindering healing. However, studies show over 80% of retreated cases achieve complete periapical healing, even with extrusion.
Area of Science:
- Dentistry
- Biomaterials
Background:
- Calcium silicate-based materials are bioactive and increasingly used in endodontic therapy.
- Accidental extrusion into periapical tissues can impede healing.
Observation:
- Presents three endodontic retreatment case reports with periapical lesions.
- Reviews 51 articles, focusing on nine case reports/series (2010-2023).
Findings:
- Over 80% of retreated cases showed complete periapical lesion healing.
- Initial treatment success rates exceeded 90%.
- Periapical healing is the common outcome, even with material extrusion.
Implications:
- Material extrusion into periapical tissues should be avoided despite high healing rates.
- Further case reports on non-MTA calcium silicate materials are recommended.
- Extended follow-up periods are advised for assessing periapical healing success.
