1 Νοε 2021 · Defluoridation techniques like the Nalgonda technique, reverse osmosis (RO), and adsorption using activated alumina have found to be promising to reduce fluoride concentration within the prescribed limits, and RO water is most widely used for drinking in fluorosis affected regions.

Fluorosis is a condition that happens because of fluoride overexposure. Fluoride is a naturally occurring mineral. In small quantities, it helps prevent tooth decay.
23 Ιουλ 2020 · The primary pathological finding of fluorosis enamel is a subsurface porosity, along with hyper- and hypomineralized bands within the forming enamel. Clinically, mild cases of dental fluorosis are characterized by a white opaque appearance of the enamel, caused by increased subsurface porosity.
The level of fluoride exposure at which dental fluorosis is minimal, and anti-caries effect maximal is said to be appropriate, being influenced by ambient temperature: Appropriate fluoride level is lower in tropical than in temperate climates. Exposure to 1 ppm of fluoride in drinking water in temperate countries has been reported to reduce ...
1 Ιουν 2023 · Introduction. Early accounts of a distinctive Colorado brown stain were paramount to discovering the link between excessive fluoride ingestion and developing a hypoplastic dentition that would later be termed dental fluorosis. [1] .
The study regarding reversal of dental fluorosis comprised only 30 patients with three months of regular follow-up. So, this sample of patients and duration of follow-up period are conclusive to observe changes in biochemical parameters but not sufficient to observe changes in clinical grading.
10 Φεβ 2022 · This shows that adsorption of fluoride is slightly reversible in nature (Eskandarpour et al., 2008). To test the prospect of granular ferric hydroxide (GFH) for fluoride removal with various other similar ions, Streat et al. (2008) conducted both batch and mini column scale studies.
