摘要

目标饮用含有最佳抗龋微量元素的水是预防全社区龋齿的有效方法。本研究旨在：(i) 确定卡塔尔商业包装水和公共自来水中氟、铜和锌的浓度；(ii) 评估商业水品牌标签上这些抗龋微量元素含量的准确性；(iii) 检查商业水和公共水样本中这些微量元素含量的季节性波动。采用离子色谱法（IC）对水样中的氟浓度进行评估，同时采用电感耦合等离子体质谱法（ICP-MS）估算铜和锌的浓度。商用水品牌的铜和锌含量低于 ICP-MS 检测限（铜为 1.22 微克/升，锌为 0.24 微克/升）。公共水样中的铜含量从 1.22 微克/升到 11 微克/升不等。公共水样中的锌含量从 5 μg/L 到 40 μg/L 不等。13 个商用水品牌标注了氟含量，其中大多数标注的氟含量为 0.1 毫克/升，与本研究结果一致。结论卡塔尔饮用水中的最佳防龋微量元素含量较低，这可能是龋齿发病率特别高的一个原因。这项研究的结果可能会促使公共卫生机构倡导在卡塔尔的饮用水中补充抗龋微量元素，从而降低龋齿的发病率。

Content of cariostatic trace elements (F, Cu, and Zn) in the commercially packaged and public tap waters of Qatar

Objectives

Drinking water containing optimal levels of cariostatic trace elements is an effective preventive approach against community-wide dental caries. This study aimed to (i) determine the concentrations of fluoride, copper, and zinc in commercially packaged and public tap water available in Qatar, (ii) assess the accuracy of the content of these cariostatic trace elements on commercial water brand labels, and (iii) check for seasonal fluctuations in the levels of these trace elements in commercial and public water samples.

Methods

Duplicate samples from 20 commercial and six public tap water sources were collected once in the summer and winter seasons. Water samples were evaluated for fluoride concentration using ion chromatography (IC), whereas copper and zinc concentrations were estimated using inductively coupled plasma mass spectrometry (ICP-MS).

Results

The fluoride content of all commercial and public water samples was below the 0.25 mg/L detection limit of the IC instrument. Commercial water brands had copper and zinc levels below the ICP-MS detection limits (1.22 μg/L for copper and 0.24 μg/L for zinc). Copper levels in the public water samples ranged from <1.22 μg/L to 11 μg/L. Zinc levels in the public water samples ranged from 5 μg/L to 40 μg/L. Thirteen commercial water brands labelled their fluoride content, with most showing labelled fluoride levels <0.1 mg/L, consistent with the results of this study. The difference in trace element content between the summer and winter water samples was not statistically significant (P > 0.05).

Conclusions

Lower optimal cariostatic trace element content in the drinking water in Qatar could be a reason for the exceptionally high prevalence of dental caries. The results of this study could lead to public health advocacy for supplementing drinking water in Qatar with cariostatic trace elements that could potentially lower the prevalence of dental caries.
