Research for developing a practical system to test non-cariogenic foods and sugar substitutes

我们开发了一种实用的系统，使用留置电极测量人体低磨牙的牙间菌斑pH值。我们的方法和数据进行了比较，由Toothfriendly糖果国际授权的三个测试实验室。经过认真考察，本课题组被批准注册为第四个实验室。通过留置系统对几种食品和口服药物进行了实际测试。日本市场上销售的润喉糖和止咳感冒糖浆，大多数都是产酸的。它们的发酵糖应该被非或低产酸甜味剂取代，以减少其致龋潜力。我们的研究工作有望与合适的糖果和制药公司合作提供社会效益。唾液作用的重要性实际上被证明在保持体内菌斑pH值高。为了切实预防龋齿，考虑吃什么、怎么吃以及什么时候吃是很重要的。这项研究工作使得有可能提出具体的信息产酸性的食物时，以及如何采取。通过报纸等大众媒体，不仅向专业领域，而且也向公众呼吁在预防龋齿方面认真考虑饮食习惯。

We developed the practical system to measure the in vivo interdental plaque-pH of low molar teeth in humans using an indewelling electrode. Our methods and data were compared with those of three test laboratories authorized by Toothfriendly Sweets International. After a careful investigation our research group is approved and registered as the fourth test laboratory. Several foods and oral medicines were tested practically by our indwelling system. Most of throat lozenges and cough-and-cold medicated syrups availabe in Japan turned out to be acidogenic. Their fermentative sugars should be substituted by non-or low-acidogenic sweetners to reduce their cariogenic potential. Our research work is expected to provide social profits in cooperation with suitable confectionery and pharmaceutical companies. The importance of salivary role was practically demonstrated in keeping in vivo plaque-pH high. It is important to think about what to eat, how to eat and when to eat in order to prevent dental caries practically. This research work makes possible to present concrete information on acidogenicity of foods when and how they are taken. The careful consideration of eating habits in preventing dental caries are made an appeal not only to the professional field but also to the general public through the mass media such as news papers etc.
