• Ion release and buffering capacity of functional filler (S-PRG) containing sealant

抄録

Ion release and buffering capacity of functional filler-containing fissure sealants (FSs) were studied. Disks of 13 mm in diameter and 1 mm in thickness (n=4) were incubated for 24 hours into 5 ml lactic acid of pH 5.5 at 37℃. ICP ion analysis revealed that BS released Si, Sr, Al, B and Na. III LC released Si, Sr, Al and Na. DE released large amount of Na. TM released the smallest ions. Fluoride measurement showed a higher value in III LC than in BS, DE or TM. The filler-containing sealants showed a substantial increase from the initial pH 5.5 of lactic acid toward neutral pH, demonstrating buffering capacity of sealants. Such changes were accompanied by modest release of alkaline ions. This was outstanding in BS.
