Broad-based targeted lipidomic analysis of dental fluorosis population in an adult population.

Dental fluorosis, as a common chronic fluoride toxicity oral disease, is mainly caused by long-term excessive intake of fluoride, which seriously affects the aesthetics and function of patients' teeth. In recent years, with the rapid development of metabolomics technology, lipidomics, as an important means to study the changes in lipid metabolism in organisms, has shown great potential in revealing the mechanisms of disease development. As a major component of cell membranes and a signaling molecule, metabolic disorders of lipids are closely related to a variety of diseases, but the specific mechanism of action in dental fluorosis is still unclear.
