BACKGROUND
The Local Government Area of Gosford implemented a water fluoridation scheme in 2008. Therefore the opportunity was taken to record the dental health of primary school children aged 5-7 years prior to the fluoridation and compare the results with other communities in NSW with different access to fluoridated water. The aim was to compare the oral health of New South Wales (Australia)s 5-7 year olds living in fluoridated, and non- fluoridated communities. One of the areas was due to implement water fluoridation and is termed the pre-fluoridation site.
METHODS
Pupils in the first year of Public and Catholic Schools in three areas of NSW were recruited. Class lists were used to draw a sample of approximately 900 per area. This number allowed for a non-response rate of up to 30 per cent and would give a sample sufficient numbers to allow statistical inferences to be drawn. Children whose parents consented received a dental examination and the clinical data was collected on mark sense cards.
RESULTS
In the 3 areas the proportion of children who received a dental examination varied; 77.5% (n = 825) for the fluoridated area, 80.1% (n = 781) for the pre-fluoridated area and 55.3% (n = 523) for the non-fluoridated area. The mean dmft was 1.40 for the fluoridated area, 2.02 for the pre-fluoridated area and 2.09 for the non-fluoridated area. These differences were statistically significant (p < 0.01). Differences were also noted in the proportion of children who were caries free, 62.6% fluoridated area, 50.8% for the pre-fluoride area and 48.6% for the non-fluoride location.
CONCLUSION
The children living in the well-established fluoridated area had less dental caries and a higher proportion free from disease when compared with the other two areas which were not fluoridated. Fluoridation demonstrated a clear benefit in terms of better oral health for young children.
背景
戈斯福德地方政府辖区于2008年实施了一项水氟化计划。因此，借此机会记录了5至7岁小学生在氟化之前的牙齿健康状况，并将结果与新南威尔士州其他获得氟化水机会不同的社区进行比较。目的是比较居住在有氟化物和无氟化物社区的澳大利亚新南威尔士州5至7岁儿童的口腔健康状况。其中一个地区即将实施水氟化，被称为氟化前地点。
方法
招募了新南威尔士州三个地区公立和天主教学校一年级的学生。使用班级名单从每个地区抽取约900名样本。这个数量允许高达30%的无应答率，并将提供一个足够数量的样本，以便进行统计推断。父母同意的儿童接受了牙科检查，并在标记感应卡上收集临床数据。
结果
在这三个地区，接受牙科检查的儿童比例各不相同；氟化地区为77.5%（n = 825），氟化前地区为80.1%（n = 781），非氟化地区为55.3%（n = 523）。氟化地区的平均乳牙龋失补牙数（dmft）为1.40，氟化前地区为2.02，非氟化地区为2.09。这些差异具有统计学意义（p < 0.01）。在无龋儿童比例方面也存在差异，氟化地区为62.6%，氟化前地区为50.8%，非氟化地区为48.6%。
结论
与其他两个未氟化的地区相比，居住在成熟氟化地区的儿童龋齿较少，无病比例较高。氟化在改善幼儿口腔健康方面显示出明显益处。
