摘要

的相关性。龋齿是儿童主要的牙齿疾病。目的:研究斯摩棱斯克市及其周边地区的饮用水质量,为实施儿童龋齿预防措施提供依据。材料和方法。我们从斯摩棱斯克7个区和6个斯摩棱斯克地区的10个取水点采集了自来水样本。斯摩棱斯克地区卫生和流行病学中心认可的检测实验室进行了水化学分析。研究分析了饮用水水质标准参数:pH值6.5 ~ 8.5,氟化物含量0.60 ~ 1.2 mg/l;水的硬度7.0-9.0(卫生法规和标准2.1.4.1116-02)。如果参数的95%置信区间在参考范围内,则认为参数是正常的。在斯摩棱斯克,集中饮用水供应系统中的氢离子浓度在正常范围内,达到7.39 (95% CI: 7.32-7.46;pH值< 0.05)。斯摩棱斯克水中的平均氟化物浓度为0.19(95%置信区间:0.14-0.23;< 0.05) mg/l,低于正常范围。在斯摩棱斯克的大部分地区,水的硬度在正常范围内,8.21 mmol/l (95% CI: 7.03-9.39;< 0.05)。但置信区间的上限为9.39 mg/l,最大值为12.0 mg/l,超出了正常范围。在斯摩棱斯克地区的城市,氢离子浓度为7.2 (95% CI: 7.02-7.38;集中供水中pH值< 0.05)的单位。斯摩棱斯克地区水中的氟化物浓度为0.45毫克/升(95%置信区间:0.23-0.68;< 0.05),说明水中缺乏氟化物。在斯摩棱斯克地区的城市,水的平均硬度为6.66 mmol/l(95%置信区间:6.00-7.03;< 0.05),低于正常值。但CI上限7.03 mmol/l和最大值7.05 mmol/l在正常范围内。斯摩棱斯克和斯摩棱斯克地区集中饮用水供应系统的水氟化物含量低。应采取紧急的社区和个人预防措施,使儿童接触氟化物。

Assessment of the drinking water quality for planning endogenic prevention of dental caries
Relevance. Dental caries is a leading dental disease in children. Aim – to study the quality of drinking water in Smolensk and its region to provide evidence for implementing dental caries preventive measures in children.Materials and methods. We took tap water samples from ten water intake points in seven districts of Smolensk and six Smolensk regions. An accredited testing laboratory of the Center for Hygiene and Epidemiology in the Smolensk Region carried out water chemical analysis. The study analyzed standard parameters of drinking water quality: pH 6.5-8.5, fluoride content 0.60-1.2 mg/l; water hardness 7.0-9.0 (Sanitary Regulations and Standards 2.1.4.1116-02). The parameter was considered normal if its 95% confidence interval was within the reference range.Results. In Smolensk, the hydrogen ion concentration in centralized drinking water supply systems is within normal limits and amounts to 7.39 (95% CI: 7.32-7.46; р < 0,05) pH units. The mean fluoride concentration in the Smolensk water is 0.19 (95% CI: 0.14-0.23; р < 0,05) mg/l, which is below the normal range. In most Smolensk districts, water hardness is within normal limits, 8.21 mmol/l (95% CI: 7.03-9.39; р < 0,05). However, the upper limit of the confidence interval of 9.39 mg/l and the maximum of 12.0 mg/l exceed the normal range. In the Smolensk region cities, the hydrogen ion concentration is 7.2 (95% CI: 7.02-7.38; р < 0,05) pH units in the centralized drinking water supply. The fluoride concentration in the Smolensk region water is 0.45 mg/l (95% CI: 0.23-0.68; р < 0,05), which demonstrates the fluoride deficiency in water. In the Smolensk region cities, mean water hardness is 6.66 mmol/l (95% CI: 6.00-7.03; р < 0,05), which is below the normal values. However, the CI upper limit of 7.03 mmol/l and the maximum of 7.05 mmol/l are within normal limits.Conclusions. The water of the centralized drinking water supply system in Smolensk and the Smolensk region is low in fluorides. Urgent community and individual preventive measures should be taken to expose children to fluoride.
