Evaluating the feasibility of calcium silicate-based sealers for strip perforation repair compared to mineral trioxide aggregate: an in-vitro study on bond strength

Puntos clave

• The aim is to evaluate the bond strength of calcium silicate-based sealers compared to mineral trioxide aggregate in repairing strip perforations.
• Conducted in vitro tests comparing calcium silicate-based sealers and mineral trioxide aggregate.
• Evaluated bond strength under varying contamination scenarios, including blood.
• Assessed different failure modes for each material.
• ProRoot MTA exhibited the highest bond strength among the tested materials.
• Blood contamination positively influenced bond strength for calcium silicate-based sealers.
• CSBSs present a feasible option for strip perforation repairs, pending further research.
