摘    要:目的 观察大黄提取液对脱矿釉质中钙溶出量的影响.方法 用不同浓度的大黄提取液和去离子水处理牙面后进行脱矿,ASCA生化分析仪对釉质脱矿后的脱矿液进行钙离子浓度的检测.结果 2 mg/ml和4 mg/ml大黄提取液处理后釉质钙溶出量<去离了水(P<0.01)、<1 mg/ml大黄提取液组(P<0.05),>2%氟化钠组但差异无统计学意义(P>0.05).1 mg/ml大黄提取液处理后釉质钙溶出量>2%氟化钠组(P<0.01),<去离子水组但差异无统计学意义(P>0.05).结论 2mg/ ml和4 mg/ml大黄提取液具有抑制脱矿釉质中钙溶出作用:2mg/ml大黄提取液为抑制钙溶出的起始有效浓度.

SUN Hao-liang,QIN Xi,LI Hui. Effects of Rhubarb Extract on Calcium Dissolved Quantity in Demineralized Enamel[J]. International Journal of Traditional Chinese Medicine, 2005, 31(1): 221-222. DOI: 10.3760/cma.j.issn.1673-4246.2009.03.013

Abstract:Objective To observe effects of rhubarb extract on Ca dissolved quantity in demineralized enmnel. Methods Demineralization was performed after treating tooth facing with rhubarb extract of different concentrations and deionized water. The concentration of Ca was detected by ASCA biochemical analyzer after demineralization. Results Dissolved quantity of demineralized Ca in the rhubarb extract group (2 mg/ml, 4mg/ml) was significantly lower than that of the deionized water group (P<0.01) and the rhubarb extract group (1 mg/ml) (P<0.05), but higher than that of 2% sodium fluoride group (P>0.05). Dissolved quantity of demineralized Ca in the rhubarb extract (1 mg/ml) group was significantly higher thanthat of 2% sodium fluoride group (P<0.01), but lower than that of the deionized water group(P>0.05).Conclusion The rhubarb exwact (2mg/ml, 4mg/ml) can inhibit Ca dissolution in demineralized enamel.The inidal effective concentration of rhubarb extract is 2 mg/ml.
Keywords:Rhubarb: Demineralization: Fluorine: Artificial enamel caries: ASCA biochemical analyzer
