Effect of fluoride on ion exchange, remineralization and acid resistance of surface enamel

Journal of Oral Pathology
L Aponte-Merced, F Feagin


In a system of constant ion activities the rates of F- exchange in enamel, under conditions of exchange alone and remineralization, depended on the concentration of F- in solutions. Acid resistance of surface minerals resulted from exchange of F- for OH- in the enamel at pH 7.0 and 4.5. The level of 0.5 mM NaF, compared to 0.05 and 6.0 mM, caused maximum rates of isotopic exchange of 45Ca and maximum acid resistance of enamel. Similarly low levels of F- may be feasible for use in caries prevention in the absence and presence of remineralization.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
