Comparative Evaluation of Sealing Ability of Mineral Trioxide Aggregate and Biodentine Used for Root Furcation Perforation Repair – A Systematic Review"

Abstract

Introduction: During endodontic operations, furcation perforations are a serious complication that might jeopardize periodontal health and the affected tooth's long-term prognosis. To stop microbial leaking and encourage periodontal repair, these perforations must be properly sealed. Because of its sealing capabilities and biocompatibility, Mineral Trioxide Aggregate (MTA) has long been regarded as the gold standard for furcation healing. A more recent calcium silicate-based substance called biodentine has gained attention as a possible substitute because of its advantageous physical characteristics and bioactivity.

Objectives: The aim of the present systematic review is to evaluate and compare the sealing ability of Mineral Trioxide Aggregate and Biodentine when used for the repair of root furcation perforations.

Methods: A comprehensive electronic search was carried out across databases such as PubMed, Scopus, and Google Scholar. The included studies compared the sealing capabilities of MTA and Biodentine in the repair of furcation perforations by in vitro or ex vivo experimental investigations. Two reviewers independently carried out the data extraction and quality assessment in accordance with PRISMA criteria.

Results:The majority of the included research evaluated the effectiveness of sealing using spectrophotometric, fluid filtration, dye penetration, or bacterial leakage techniques. Although MTA and Biodentine both showed adequate sealing capabilities, a number of studies found that Biodentine performed better or on par with MTA in terms of marginal adaption and decreased leakage.

Conclusions: Root furcation holes can be successfully repaired using both mineral trioxide aggregate and biodentine. Although MTA is still often used, Biodentine seems to provide a similar sealing capacity combined with benefits like quicker setting time and better handling. To confirm these results and encourage evidence-based material selection in clinical practice, more standardized clinical and in vivo research is advised.
