酸蚀是一种牙齿磨损現象,指的是酸(非细菌帶來)溶解牙齒後牙齒出現磨損狀況,牙齒磨損情況不可逆转。[1]牙齿糜烂是5-17岁儿童最常见的慢性疾病[2]。飲用果汁是造成牙齒酸蚀的原因之一[3]。酸蚀的過程先从牙釉质开始,牙釉质变薄後,腐蝕過程蔓延至牙本質,此時牙齿呈现暗黄色,並引發牙本质过敏[4]。
引起牙齒腐蚀最常见原因是飲用酸性食物和饮料(例如果汁[5])。一般来说,PH值低于5.0-5.7的食物和饮料都会引发牙齿腐蚀。[6]许多临床和实验室报告都将牙齒糜烂与饮用過多的饮料联系起来。一些酒精和水果饮料、橙汁等含有柠檬酸的果汁和可乐等軟性飲料(其中柠檬酸和磷酸是导致腐蝕的原因,碳酸則不是)被认为是引發牙齒酸蝕的因素之一。[7] 此外,葡萄酒已被证明可以腐蚀牙齿,因為葡萄酒的pH值會低至3.0-3.8。[6]氯化過的游泳池的水[8]和胃酸反流等也會侵蚀牙齒。[9] 在患有慢性疾病的儿童中,他們服用含有酸性成分的药物也是引發牙齒腐蝕的原因之一。[10]人們在化石中也發現有動物出現牙齿腐蚀的現象,很可能是由它們食用的酸性水果或植物所造成。[1]
