Three marketed pit and fissure sealants were employed. They were cured in mold (dia.: 13mm, thickness: 1mm). And then the sealant specimen was put into pH4.0 solution (lactic acid aq.) together with a human tooth fragment. Acidity of solution was measured daily. After one week passed, density of calcium and other ions in solution were measured. Transition of pH value was different. Multiple ions releasing material correlated to be a stability of teeth surface. That is, some sealant materials could inhibit demineralization of human teeth. And, effects of sealants showed different demineralization capacity through solution.
