本研究目的在于探讨饮水含氟量与菌斑含氟量及原位菌斑产酸能力之间的关系。对菌斑含氟量、DMFS、菌斑重量之间的关系进行了分析。用氟离子选择电极法测定了高氟区(水 F=1.90ppm)49人、低氟区(水 F=0.03ppm)48人的牙菌斑含氟量,用微型锑电极测定了高氟区20人、低氟区18人的原位菌斑 pH。结果表明,饮水含氟量显著地影响菌斑含氟量,高氟区的菌斑含氟量是低氟区的2倍。茵斑含氟量与菌斑重量及 DMFS 有关。用微型锑电极测定原位菌斑 pH,未能发现高低氟地区原位菌斑pH 的显著差异。
The purpose of this study is to explore the relationship between fluoride content in drinking water and fluoride content in plaque and in situ plaque acid production capacity. The relationship between the amount of fluoride in plaque, DMFS and plaque weight was analyzed. Fluorine ion selective electrode method was used to determine the fluoride content of dental plaque in 49 persons with high fluoride area (water F = 1.90ppm) and 48 persons with low fluorine area (water F = 0.03ppm). The fluoride area 20, low fluoride area 18 in situ plaque pH. The results showed that fluoride content in drinking water significantly affected the amount of fluoride in the plaque, and the content of fluoride in the plaque in the high-fluorine area was twice that of the low-fluorine area. Ephedrine fluoride content and plaque weight and DMFS. Micro-antimony electrode was used to detect the in-situ plaque pH, and no significant difference in in-situ plaque pH between the high and low fluoride regions was found.
