1、乳饮料对年轻恒牙脱矿作用的研究1.天津医科大学总医院天津300052;2.天津医科大学总医院口腔内科天津300052【摘要】目的:研究目前市场畅销的乳饮料对年轻恒牙釉质的脱矿作用,比较不同饮料对牙釉质的脱矿程度。方法:将显微镜下观察无龋、无裂纹及釉质发育缺陷的42个釉质样木,随机分成四组:A为每日活菌组,B为沙棘酸牛奶组,C为酸牛奶组,每组12个样木,D为对照组,含6个样木;四组牙釉质块均用相同人工唾液储存于同一条件下。将每组样木经过不同的饮料及不同的方法处理后通过能谱分析仪及扫描电镜分析其表面形态及钙磷含量的变化并用SPSS19
2、.0分析。结果:三种乳制品饮料都会导致釉质的脱矿。经去离子水冲洗后的牙釉质较未经去离子水冲洗的牙釉质脱矿程度低。结论:不同的乳饮料均会导致牙釉质脱矿,但其脱矿程度略有差别。提醒广大青少年合理饮用乳制品饮料,同时建议饮用饮料后及时漱U,以预防或减少其对牙釉质的脱矿作用,降低牙齿的患龋率。【关键词】乳饮料,年轻恒牙,脱矿AnexpelrimentalstudyonyoungpermanentteethenameldeminerlaziationbymilkdrinksBaiXiangyu,ZhangJieTianjinMedicalU
