摘要
目的:探讨新研制的唾液替代品对早期釉质龋的再矿化作用。方法:选择正畸和牙周病拔除的无龋牙10颗,用0.1mol/L乳酸(pH4)在37℃条件下作脱矿浸泡6h,进行人工龋实验,然后模拟口腔环境,37℃恒温下用研制的唾液替代品在37℃条件下进行再矿化处理,每天2次,分别于1周、2周测试实验牙表面硬度。结果:脱矿的牙釉质经唾液替代品再矿化后,硬度值明显高于矿化前的硬度,硬度恢复分别为55.34%、77.19%(P<0.01)。
Objective:To find out the remineralization of the new salivary substitute to the early enamel caries Method:Ten uncaries teeth was selected,which was extracted because of orthodontic therapy and periodontitis In order to make artificial caries experiment at 37℃,the teeth was soaked into 0 1 mol/L lactacid (pH 4) for 6 hours,so as to be dismineralized Then imitating oral circumstance at 37℃,the teeth was remineralized twice every day by the new salivery substitute,and for the first and second weeks,the hardness of the experimental teeth were measured respectively Result:After the dismineralized enamel was remineralized by the salivary substitute,the hardnesss was obvibnsly superior to that before remineralized The renemed hardness were 55 34% and 71 19%,respectively (P<0 01) Conclusion:This new salivary substitute promots the dismineralized teeth to be remineralized
