常见致龋菌代谢组学鉴定的初步研究
代谢组学 核磁共振技术 细菌 鉴定
2010/9/8
目的初步将基于核磁共振的代谢组学方法应用于口腔致龋菌的鉴定，期望寻找一种能快速鉴定口腔致龋菌的方法。方法在改良TPY培养基中接种变形链球菌及粘性放线菌，用比浊法绘制生长曲线，选择两种细菌生长后4个时期的培养液检测核磁共振波谱，用主成分分析法进行数据分析。结果主成分分析显示两组数据内部有集中的聚类关系，可以区分两种细菌。结论代谢组学技术有望应用于口腔细菌的快速鉴定。
口臭研究模型的建立及其对口腔致臭菌的确定
口臭 挥发性硫化合物 口臭模型
2010/8/27
目的建立一个可模拟口臭代谢过程的唾液沉淀物系统，同时分析几种细菌对口臭产生的影响，为致臭菌的确定提供依据。方法收集10名牙周健康个体的刺激性全唾液10份。调整离心全唾液的上清液和沉淀物的比例，建立口臭研究模型，在37 ℃兼性厌氧条件下孵育使其产生臭味，7 h内每隔1 h分别用鼻闻法检测气相和液相的臭味指数，用Halimeter测量挥发性硫化合物（VSCs）水平，用玻璃电极测量pH值。在经过1 h孵...

目的比较2种口腔健康教育方式对中学生口腔卫生状况的改善效果，寻求改善效果较佳的口腔健康教育方式。方法在四川省德阳市市区随机选取3所中学，每个学校均抽取103名12岁学生，男女比例接近1∶1。按学校随机将学生分为3组：老师模式组由口腔医生对老师进行口腔健康知识培训，再由老师对学生上健康教育课，学生在家刷牙；家长模式组由口腔医生对家长进行口腔健康教育培训，通过提高家长的口腔保健意识间接影响学生的口腔健...
不同饮料对不同龋敏感儿童牙菌斑pH值的影响
牙菌斑 饮料 pH值测定 龋病
2010/9/8
目的比较不同种类的饮料对龋敏感儿童及无龋儿童牙菌斑pH值的影响。方法采用微型蜂式pH指示电极原位测试儿童牙菌斑pH值。选择四川省成都市幼儿园3～5岁无龋儿童10名和龋敏感儿童10名作为研究对象，观察其饮用可口可乐、统一鲜橙多及乐百氏AD钙奶饮料后牙菌斑pH值的动态变化。结果无龋和龋敏感组儿童牙菌斑的静止pH值有统计学差异（ P<0.05）。饮用饮料后，各组牙菌斑pH值均下降，约5～10 min后达...
健康牙龈龈下菌斑胰蛋白酶样酶水平的测定
牙菌斑
2010/8/27
胰蛋白酶样酶（ trypsin- like enzyme, TLE）是造成牙周组织破坏的重要因素之一，Loesche等[1]认为牙周病变中TLE水平与牙周病的严重程度呈显著的正相关。本研究通过苯甲酰精氨酸萘酰胺（ benzoyl DL arginine naphthlamide，BANA）水解试验对健康牙龈龈下菌斑内TLE水平进行测定，以对今后的牙周病研究提供参考。
冷酸解离-氟离子电极法测定牙膏中总氟含量的评价
冷酸解离-氟离子电极法 含氟牙膏 氟含量
2010/8/26
目的探讨冷酸解离- 氟离子电极法测定含氟牙膏中总氟含量的可行性和可靠性。方法选择市售无氟牙膏和含氟牙膏各4个品种，采用2 mol/L高氯酸、室温、过夜的解离条件，对无氟牙膏加入标准氟后测定总氟量，对市售含氟牙膏进行总氟测定，以确定此方法的可行性和可靠性。结果牙膏中使用的氟化物与摩擦剂配伍不同对氟测定结果有影响。冷酸解离- 氟离子电极法对于含钙类摩擦剂的无氟牙膏加入标准氟（ 单氟磷酸钠）后总氟的回收...
