Dental erosion is a common problem in modern societies, owing to the increased consumption of acid drinks such as soft drinks, sports drinks, fruit juice. Examining the enamel surface with the Atomic Force Microscopy (AFM) enables more precise registering and defining the changes of enamel surface structure and microhardness. This method can be used to compare the efficiency of application of different preventive and therapy materials and medicaments in dentistry. The chronic regular consumption of low pH cola drinks encouraged the erosion of the teeth. The loss of anatomy and sensitivity are direct results of acid cola dissolving coronal tooth material. Under the influence of coca cola, a change of crystal structure and nanomorphology on enamel surface occurs.
This paper reflects dental damage from abusive cola drinking, and the clinical presentation can be explained from data presented in this thesis.
The trial was conducted on a total of 40 extracted teeth which were divided into two groups treated with the solution of coca cola during 5 minutes, and then prepared and tested with a standard AFM procedure, type SPM-5200. Quantitative analysis was performed by comparing the roughness parameters (Ra) of the treated and non-treated sample.
Based on the test of a hypothesis of the existence of differences between the treated and untreated sample, with an application of a t-test, it is shown that there are statistically highly significant differences between Ra of the treated sample with a 5-minute treatment of coca cola and Ra of the same sample without the treatment.
Use of AFM enables successful monitoring of changes on enamel surface as well as the interpretation of the ultrastructural configuration of the crystal stage and the damage created under the influence of different external factors.
由于软饮料、运动饮料、果汁等酸性饮料的消费量增加,牙侵蚀在现代社会是一个常见问题。用原子力显微镜(AFM)检查牙釉质表面能够更精确地记录和界定牙釉质表面结构和显微硬度的变化。该方法可用于比较牙科中不同预防和治疗材料及药物的应用效果。长期经常饮用低pH值可乐饮料会导致牙齿侵蚀。牙体外形丧失和敏感是酸性可乐溶解牙冠牙体组织的直接结果。在可口可乐的影响下,牙釉质表面的晶体结构和纳米形态会发生变化。
本文反映了过量饮用可乐对牙齿的损害,其临床表现可从本论文所呈现的数据中得到解释。
试验共对40颗拔除的牙齿进行,将其分为两组,用可口可乐溶液处理5分钟,然后采用标准AFM程序(型号SPM - 5200)进行制备和测试。通过比较处理组和未处理组样本的粗糙度参数(Ra)进行定量分析。
基于对处理组和未处理组样本之间存在差异这一假设的检验,应用t检验表明,经5分钟可口可乐处理的样本的Ra与未处理的同一样本的Ra之间在统计学上存在高度显著差异。
使用AFM能够成功监测牙釉质表面的变化,以及解释晶体阶段的超微结构构型和不同外部因素影响下产生的损害。
