碳酸饮料与清洁级大鼠龋齿发生相关性的实验研究

The study on relation of clean grade rats deontal caries occurrence and carbonated drinks

目的比较不同的酸性饮料对清洁级大鼠龋齿发生率的影响。方法将40只清洁级BABL/c鼠分为去离子水组(A组)、可口可乐组(B组)、鲜橙多组(C组)和雪碧组(D组),每组10只,去离子水组为对照组,其余为试验组,采用Keyes经典评分方法进行龋齿发生的评估。结果除去离子水外其余实验饮料均对实验鼠的牙齿均有酸蚀作用,并可以导致龋齿。结论碳酸饮料对牙釉质具有酸蚀作用,可以导致龋齿。

Objective The experimental study on compare the relation of different acidic drinks with rast dental caries. Methods 40 clean grade BABL/c rats were divided into deionized water group （groupA）,Coca-Cola group （groupB）, orange juice group （groupC） and Sprite group （groupD）, 10 rats each group, deionized watere group as control group, the other as the experimental group, using the classic Keyes score method to evaluate the occurrence of dental caries. Results Deionized water has the cariogenie effect on the enamel in the experimental greup,carbonated drinks has acid effect on rat teeth, and can lead to dental caries. Conclusion Carbonated drinks have acid effect on enamel, and can lead to dental caries.
