概括
在澳大利亚北领地的儿童中,社区水的化显著减少了牙损伤. 这种具有成本效益的公共卫生干预措施改善了偏远人口的口腔健康结果.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 牙科研究 牙科研究
背景情况:
- 社区水化 (CWF) 是一种公认的,具有成本效益的策略,用于在人口层面减少牙损伤.
- 牙损伤不成比例地影响着澳大利亚北领地 (NT) 的偏远和非常偏远地区的土著儿童.
研究的目的:
- 评估CWF在偏远NT社区儿童中减少牙的有效性.
- 通过差异差异分析 (DiD) 评估CWF实施的影响.
主要方法:
- 通过使用2008年至2020年NT中24546名儿童 (1至17岁) 的口腔健康数据进行了DiD分析.
- 分析了来自50个偏远社区的数据,将2014年实施CWF的社区的儿童 (治疗组) 与自然充足或不足的化物水平 (对照组) 的社区的儿童进行了比较.
- 在CWF实施之前和之后,使用腐烂,缺失和填充牙 (dmft/DMFT) 指数测量牙损伤.
主要成果:
- 与对照组相比,CWF的实施导致治疗组儿童的牙损伤率在统计学上显著下降.
- 治疗组的儿童在dmft/DMFT中平均下降0.28 (p=0.001).
- 在较年长的年龄组 (7-10岁和11-17岁) 观察到显著减少,牙受影响分别减少了0.32和0.40.
结论:
- 社区水的化有效地实现了在偏远的NT社区儿童的牙损伤人口水平的减少.
- 这项研究证实了DiD方法对公共卫生政策评估的有用性.
- NT的CWF政策已经明显改善了高牙负担的偏远地区儿童的口腔健康结果.

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

01:18Effects of EDTA on End-Point Detection Methods
264
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
