摘要
目的:检测五倍子与没食子乙醇提取物处理脱矿后的牙釉质的表面硬度,考察二者对釉质再矿化的影响。方法:采用化学方法建立牙齿龋病模型,分别经五倍子和没食子乙醇提取物处理,利用显微硬度仪测试各组硬度。结果:经五倍子和没食子乙醇提取物处理后的釉质表面硬度值分别为345.4 kg/mm2和330.6 kg/mm2,再矿化的效果差异具有统计学意义(P<0.01),对照组经去离子水处理后的釉质表面硬度值为313.0 kg/mm2,硬度差异无统计学意义(P>0.05)。结论:五倍子提取物(80 mg/mL)与没食子提取物(80 mg/mL)对人工脱矿釉质均有再矿化的能力,五倍子再矿化能力强于没食子。
Objective： To detect the hardness of artificial demineralized enamel treated with ethanol extract of Galla Chinensis and Galla Halepensis.Methods： Caries models were established using chemical methods and treated with the extracts of Galla Chinensis and Galla Halepensis.The surface hardness was determinated using micro hardness tester.Results： The average surface hardness values are 345.4 kg/mm 2,330.6 kg/mm 2 and 313.0 kg/mm 2 respectively under the treatments of extracts of Galla Chinensis,Galla Halepensis and deionized water.Conclusion： Data showed both remineralizing capacities of Galla Chinensis extract（80 mg/mL） and Galla Halepensis extract（80 mg/mL）.The Galla Chinensis extract exhibited stronger effects compared to that of Galla Halepensis extract.
