The aims of this study were to: (1) analyse the fluoride content of tank water; (2) determine whether the method of water collection or storage influenced fluoride content; and (3) survey participant attitudes towards water fluoridation.
Plastic tubes and a questionnaire were distributed through dentists to households with water tanks in Victoria. A midstream tank water sample was collected and fluoride analysed in triplicate using ion chromatography
All samples (n = 123) contained negligible amounts of fluoride, with a mean fluoride concentration of <0.01 ppm (range: <0.01-0.18 ppm). No statistically significant association was found between fluoride content and variables investigated such as tank material, tank age, roof material and gutter material. Most people did not know whether their tank water contained fluoride and 40.8% preferred to have access to fluoridated water. The majority thought fluoride was safe and more than half of the respondents supported fluoridation. Fluoride content of tank water was well below the optimal levels for caries prevention.
People who rely solely on tank water for drinking may require additional exposure to fluoride for optimal caries prevention.
本研究的目的是:(1)分析水箱水的氟含量;(2)确定集水或储水方法是否会影响氟含量;(3)调查参与者对水氟化的态度。
通过牙医向维多利亚州有水箱的家庭分发塑料管和问卷。采集水箱水的中游水样,并使用离子色谱法对氟进行三次分析。
所有样本(n = 123)的氟含量均可忽略不计,平均氟浓度<0.01 ppm(范围:<0.01 - 0.18 ppm)。在氟含量与所研究的变量(如水箱材料、水箱使用年限、屋顶材料和排水沟材料)之间未发现统计学上的显著关联。大多数人不知道他们的水箱水是否含有氟,40.8%的人更倾向于使用含氟水。大多数人认为氟是安全的,超过一半的受访者支持水氟化。水箱水的氟含量远低于预防龋齿的最佳水平。
仅依靠水箱水饮用的人群可能需要额外摄入氟以实现最佳的龋齿预防效果。
