23 Ιουλ 2020 · Although teeth with mild dental fluorosis may be more resistant to dental decay due to the higher levels of fluoride contained in the enamel surface, teeth with severe fluorosis are more susceptible to decay, most likely because of the uneven surface or loss of the outer protective layer .

Dental fluorosis is a specific condition due to chronic ingestion of excessive fluoride during enamel formation. The cleavage and removal of enamel proteins are disturbed. Retention of the proteins and water results in varying degrees of subsurface porosities related to the severity of fluorosis.
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.
What causes fluorosis? Fluorosis occurs due to fluoride overexposure. That means you ingest (swallow) excess amounts of fluoride over a long period of time. The way it happens depends on the type of fluorosis. Dental fluorosis happens when a child consistently ingests too much fluoride while their permanent teeth are still forming under their gums.
Fluoride can prevent dental caries; however, excessive fluoride can cause DF. Fluorosis is also known as endemic fluorosis (EF), and it is mainly caused by consuming items that are ubiquitous in the natural environment, such as drinking water, brick tea, or coal with a high fluoride content.
Dental fluorosis is a fluoride-induced disturbance in tooth formation, which results in hypomineralized enamel with increased porosity. It is caused by excessive intake of fluoride, but only during the period of tooth development.
Previously, it was suggested that soft tissue changes due to excessive fluoride intake in children may be reversible by withdrawal of fluoride intake, dietary supplementation with calcium, vitamin D3, ascorbic acid, and antioxidant; however, there is no evidence of reversible changes in dental hard tissue.
