根据Stephan的研究,随着含漱糖水,菌斑pH会迅速下降,然后缓慢回升。显然,这种酸的滞留堆积会引起菌斑基质中沉积的矿物、结合的无机盐类和牙釉质的溶解。一些学者已就给糖前后菌斑液中钙、磷浓度变化进行了一定的研究。本文旨在进一步地测定分析在同样条件下,人牙菌斑细胞外液中钙、磷的变化,以及这些变化与外液中pH变化的关系,并探讨龋损发生的液相环境中钙、磷移动方向,现将其报导如下。材料与方法一、样品的收集选12名住校中学生(男、女各半,年龄14—16岁),根据其各自的DMF值分为两
According to Stephan's research, the plaque pH drops rapidly with the rinsing of syrup and then slowly rises. Obviously, this acid build-up can cause the dissolution of deposited minerals, bound inorganic salts and enamel in the plaque matrix. Some scholars have made a certain study on the changes of calcium and phosphorus in plaque fluid before and after giving sugar. The purpose of this paper is to further analyze and analyze the changes of calcium and phosphorus in the extracellular fluid of human plaque under the same conditions and the relationship between these changes and the changes of pH in the extracorporeal fluid and to explore the relationship between calcium, Phosphorus movement direction, it is reported as follows. Materials and methods First, the collection of samples Select 12 resident school students (male and female half, aged 14-16 years old), according to their respective DMF value is divided into two
