Is a 0.3g powder of hydraulic bioceramic material for repair and vital pulp therapy.
Portland cement is NOT used as a raw material.
RetroMTA is a powder consisting of fine, hydrophilic particles that set in the presence of water and form a strong impermeable barrier.
It contains a hydraulic calcium zirconia complex as a contrast media.
Setting time is 150 seconds.
It has no discoloration even in case of blood contamination. Therefore it is ideal for aesthetic repair material. It contains no heavy metals.
It has no toxicity to cells within 48 hours.
This means it is a substance for vital pulp therapy. (pulp capping, pulpotomy and pulpectomy)
In vivo condition, Initial Ph is up to 12.5 and down to 7.8~8.0 in 4 weeks.
Ex vivo study shows it has a high potential for biomineralization.
