【摘要】：目的探究可乐饮料对口腔牙釉质的早期损害。方法收集40颗下颌第三磨牙制备120个牙釉质样本块,将120个样本采用随机数表法分为4组,每组30个釉质块,其中一组为对照组。检测百事可乐、非常可乐、可口可乐3种饮料中的磷钙含量,分别采用微量化学分析法和维氏显微硬度仪检测经3种可乐饮料处理1、12和24 h后釉质块中磷钙含量的变化情况和釉质块表面显微硬度变化情况。结果百事可乐、非常可乐和可口可乐的磷浓度分别为(3.46±0.32)、(3.87±0.26)和(3.46±0.29)mmol/L,钙浓度分别为(3.58±0.25)、(0.09±0.06)和(1.32±0.19)mmol/L,3种可乐饮料均会导致牙釉质中钙磷溶出。磷溶出浓度由大至小分别为百事可乐、非常可乐和可口可乐,钙溶出浓度由大至小分别为非常可乐、可口可乐和百事可乐,且随着时间的延长,磷钙溶出浓度逐渐降低,差异有统计学意义(P0.05)。3种可乐饮料导致牙釉质表面显微硬度值降低的程度由大至小分别为非常可乐、可口可乐和百事可乐,且随着时间的延长,牙釉质表面显微硬度值逐渐降低,差异有统计学意义(P0.05)。结论可乐饮料均会导致牙釉质显微硬度降低,导致牙釉质酸蚀,导致牙釉质表面脱矿程度最严重的为非常可乐。
[Abstract]:Objective to explore the early damage of oral enamel caused by cola drink. Methods 120 enamel samples were prepared from 40 mandibular third molars. 120 samples were randomly divided into 4 groups with 30 enamel masses in each group, one of which was the control group. The contents of phosphorus and calcium in three kinds of drinks, Pepsi-Cola, very Coke and Coca-Cola, Microchemical analysis and Vickers microhardness analyzer were used to detect the changes of phosphorus and calcium content in enamel and microhardness of enamel after treatment with three kinds of cola drinks for 12 and 24 hours respectively. Results the phosphorus concentrations of Pepsi-cola (3.46 卤0.32), (3.87 卤0.26) and Coca Cola (3.46 卤0.29) mmol / L, calcium concentrations (3.58 卤0.25), (0.09 卤0.06) and (1.32 卤0.19) mmol / L 路L ~ (-1) C _ (-1) respectively resulted in calcium and phosphorus dissolving in enamel. The concentration of phosphorus dissolved from large to small is Pepsi, very cola and Coca-Cola, and calcium from large to small is very cola, Coca Cola and Pepsi, respectively, and the concentration of phosphorus and calcium dissolves gradually decreases as time goes on. The difference was statistically significant (P0.05). The microhardness of enamel surface decreased from large to small to large to small, respectively. The microhardness of enamel surface decreased gradually with the time prolonging. The difference was statistically significant (P0.05). Conclusion Coke drinks can decrease the microhardness of enamel, cause enamel acid erosion, and the most serious demineralization of enamel surface is very cola.
