High consumption of nonalcoholic beverages is one of the causes of dental erosion. Annual consumption of beverages in Iran is 48 LPCY (Lit per capita per year) that is equal to 144 bottles per capita in year and is relatively a high rate. Taking this into consideration, the present study was planned to determine the pH and fluoride content of beverages consumed in Kerman, south east of Iran.
In a descriptive cross-sectional study during 2006-2007, samples of any type of beverages in Kerman were taken once every 4 months and each sample was examined for its acidity and fluoride content in ambient and refrigerator temperatures. A total of 744 experiments were conducted on 62 brands of beverages with different colors to determine the acidity and on 31 brands of beverages to determine their fluoride content. Acidity was determined by pH-meter in the ambient temperature and refrigerator temperature (+4◦C). Fluoride content was determined using specific electrode method. Data analysis was done by SPSS software package.
Mean acidity of the consumed beverages in Kerman was 2.55 and 2.78 mg/L in the ambient temperature and refrigerator temperature, respectively. Mean fluoride concentration in the temperature of the ambient and refrigerator were 1.13 and 1.27 mg/L respectively. Therefore beverages consumption in Kerman had a higher acidity than national standard.
Since some of the consumed beverages in Kerman are distributed and consumed in other parts of Iran as well, necessary precautions for controlling dental erosion especially in Kerman residents should be taken.
非酒精饮料的高消费量是牙齿侵蚀的原因之一。伊朗的饮料年消费量为48升/人/年（每人每年升数），相当于每人每年144瓶，这一比率相对较高。考虑到这一点，本研究旨在确定伊朗东南部克尔曼市所消费饮料的pH值和氟含量。
在2006 - 2007年的一项描述性横断面研究中，克尔曼市的各类饮料样本每4个月采集一次，每个样本在环境温度和冷藏温度下检测其酸度和氟含量。对62个不同颜色品牌的饮料进行了744次酸度测定实验，对31个品牌的饮料进行了氟含量测定实验。酸度在环境温度和冷藏温度（+4℃）下用pH计测定。氟含量用特定电极法测定。数据分析采用SPSS软件包进行。
克尔曼市所消费饮料在环境温度和冷藏温度下的平均酸度分别为2.55和2.78毫克/升。环境温度和冷藏温度下的平均氟浓度分别为1.13和1.27毫克/升。因此，克尔曼市的饮料消费酸度高于国家标准。
由于克尔曼市消费的一些饮料也在伊朗其他地区分销和消费，所以应采取必要的预防措施来控制牙齿侵蚀，特别是针对克尔曼市居民。
