Abstract

A prolonged acidic ambience of oral environment will lead to demineralization process. It caused erosion to enamel surface after long time of exposure. Acidic beverages become the external factor of dental erosion. Energy drink is one of popular beverages which has acid ingredients and pH value below the critical pH (5.5). The objective is to determine the effect of energy drink on microhardness of dental enamel (in vitro). Methods that were used in this study was experimental pre test - post test with control group design. A total of 36 premolar were used as samples which were divided into energy drink group and control group of artificial saliva. The treatment group were immersed for 8 cycle for 7 days. Dental enamel microhardness were measured by Vickers Hardness Tester before and after treatment. The result of this study was microhardness mean of enamel surface decreased from 306 VHN to 262 VHN after immersion for energy drink group and no significant difference in artificial saliva group. Independent T-test analysis showed p value <0,005, thus concluding there was significant difference between two groups. The conclusion of this study there was significant effect of energy drink immersion to dental enamel microhardness.

功能饮料对牙釉质显微硬度的影响(体外)

长期的口腔酸性环境会导致脱矿过程。长时间暴露在牙釉质中，对牙釉质表面造成侵蚀。酸性饮料成为牙齿腐蚀的外在因素。功能饮料是一种受欢迎的饮料，它含有酸性成分，pH值低于临界pH值(5.5)。目的是确定能量饮料对牙釉质显微硬度(体外)的影响。本研究采用实验前测-后测及对照组设计。以36颗前磨牙为研究对象，分为能量饮料组和人工唾液对照组。治疗组浸泡8个周期，共7 d。用维氏硬度计测定治疗前后牙釉质显微硬度。结果表明，功能饮料组浸泡后牙釉质表面显微硬度平均值由306 VHN降至262 VHN，而人工唾液组无显著差异。独立t检验分析p值< 0.005，两组间差异有统计学意义。结论:能量饮料浸泡对牙釉质显微硬度有显著影响。
