生物活性玻璃对体外脱矿釉质再矿化的影响
Effect of bioactive glass on demineralization enamel remineralization in vitro
摘要
Abstract
Aim:To observe the effect of bioactive glass on the remineralization of demineralization enamel .Methods:Forty bovine teeth were subjected to establish demineralization enamel model , and then were allocated into four groups ran-domly(10 in each group) and treated with 6% bioactive glass, casein phosphopeptide amorphous calcium phosphate (CPP-ACP),2%sodium fluoride(NaF) and deionized water,respectively.Then they were subjected to the pH-cycling,two times a day and 5 minutes each time, cycling for 15 days for remineralization.The surface microhardness(SMH)of the enamel before demineralization,before and after remineralization were measured by microhardness detector .Thickness of fluorescence be-neath the surface of early enamel caries in the demineralization area and the remineralization area were detected by fluores -cence microscopy .Results: The SMH after remineralization in bioactive glass , CPP-ACP and NaF groups was higher than those before remineralization, and the change of bioactive glass group was the highest (P<0.05).The thickness of fluores-cence in the remineralization area was lower than that in the demineralization area in the four groups ( P<0.05), and the demineralization depth of bioactive glass ,CPP-ACP and NaF groups was higher than the deionized water group (P<0.05). Conclusion:6%bioactive glass solution had better effect on remineralization of demineralization enamel .关键词
