Summary: This study investigated the association between prenatal maternal urinary fluoride levels and symptoms of attention-deficit/hyperactivity disorder (ADHD) in children aged 8 and 11 years. The results showed no association between maternal urinary fluoride levels during pregnancy and cognitive problems-inattention symptoms at 8 or 11 years old. However, at age 11, there was a significant inverse association between maternal urinary fluoride levels and being categorized as a cognitive problems-inattention case. These findings contradict previous studies and highlight the need for further population-based research to confirm or challenge these results.

Summary: This study examined the association between maternal exposure to fluoride during pregnancy and children's intelligence and executive function. The findings suggest that children whose mothers were fully exposed to fluoridated drinking water had higher IQs and better executive functions.

Summary: This study discusses the toxicity of fluoride in the environment, related defluoridation technologies, operational costs and effectiveness. It is noted that adsorption is currently the main technique for defluoridation, but requires further development. Additionally, industrial effluents may have high fluoride concentrations, traditional treatment methods are ineffective and hybrid treatments are needed.

Summary: This study found that there was no significant difference in urinary fluoride (UF) levels between pregnancy and one year postpartum, but UF levels increased every 10 gestational weeks during pregnancy. Different dietary influences on UF levels were identified in each state, with calcium supplements decreasing UF only during pregnancy and table salt use increasing UF only at one-year postpartum.

Summary: This narrative review examines the use of biomarkers to measure fetal fluoride exposure in pregnant women and discusses the limited understanding of how pregnancy affects fluoride metabolism. It highlights the potential impact of pregnancy on fluoride absorption, distribution, and excretion, and emphasizes the need for more research on this topic.

Summary: In animal studies, the combination of in utero fluoride exposure and low iodine has more negative effects on offspring learning and memory. This study evaluated whether maternal urinary iodine concentration modifies the association between maternal urinary fluoride and intelligence in boys and girls. The results suggest that adequate iodine intake during pregnancy may minimize fluoride's neurotoxicity in boys.

Summary: Exposure to excessive fluoride is associated with adverse health outcomes, but the relationship between fluoride exposure and serum uric acid levels is not well studied. This research found a potential link between fluoride exposure and hyperuricemia in adolescents, with higher plasma and water fluoride concentrations associated with increased risk of hyperuricemia. Further studies are needed to explore the long-term effects of low levels of fluoride exposure on hyperuricemia and related health outcomes.

Summary: This article discusses the harmful effects of fluoride ions in drinking water and the application of metal-organic frameworks (MOFs) in detecting and removing fluoride ions. It also elaborates on the adsorption performance of various MOFs towards fluoride and reveals the detection and adsorption mechanisms comprehensively.

Summary: The study successfully evaluated the defluoridation of groundwater using Moringa oleifera Lam as a natural coagulant in the C/F/S process followed by ultrafiltration membrane process. The combined process showed promising results in removing fluoride from groundwater, making it a potential alternative for public water supply.

Summary: This meta-analysis systematically evaluated the effects of water improvement and defluoridation in fluorosis-endemic areas in North and South China. The results showed significant reductions in dental fluorosis and skeletal fluorosis prevalence, as well as urinary fluoride levels after water improvement. Additionally, the effects were greater in South China compared to North China.

Summary: Recent reports have associated high levels of fluoride exposure during pregnancy and infancy to low intelligence quotient. Both fluoride and iodine are halogens, and it has been suggested that fluoride may interfere with the role of iodine in thyroid function. This scoping review explored the effects of iodine and fluoride exposure during pregnancy on thyroid function and offspring neurodevelopment, highlighting the need for further studies.

Summary: A systematic review and meta-analysis was conducted to explore the possible harmful effect of fluoride exposure on cognitive neurodevelopment in children. The majority of studies suggested an adverse effect, especially at low levels of exposure, but the role of confounding factors needs to be further investigated.
