The ultrastructure of fluorosed human dental enamel
European Journal of Oral Sciences, 1974abstract— More than 80 specimens of enamel from 20 ground sections of eight teeth showing severe dental fluorosis have been examined in the transmission electron microscope. The study has shown that the prisms have normal size and form, but are surrounded by large periprismatic gaps. The individual crystals commonly appear in cross sections as regular,

Histological Features of Fluorosed Human Dental Enamel
Caries Research, 2009The present study describes the histological features of enamel in teeth showing either mild or severe fluorosis. Sections were examined in transmitted and polarized light after imbibition in aqueous media or alcohols and quinoline. For semiquantitative study contour maps were prepared. Furthermore quantitative imbibition studies were performed along a

Effect of a Mineralizing Solution on Sections of Fluorosed Human Dental Enamel in vitro
Caries Research, 2009The present study was undertaken to investigate the mineral uptake in fluorosed enamel in vitro. Bucco-lingual sections of severely fluorotic teeth were exposed to a mineralizing calcium phosphate solution supersaturated with respect to hydroxyapatite and under-saturated with respect to other calcium phosphates in order to favour apatite formation. The

Abordagem minimamente invasiva para tratamento de fluorose dental com associação de técnicas
Full Dentistry in Science, 2022A fluorose dentária corresponde a um defeito estrutural no esmalte causado pela exposição prolongada ao flúor durante a formação do germe dentário. As associações de procedimentos minimamente invasivos neste esmalte alterado têm se mostrado um tratamento seguro e eficaz. O objetivo deste trabalho é relatar um caso clínico de manchas de fluorose através

3D scanning electron microscopy applied to surface characterization of fluorosed dental enamel
Micron, 2016The enamel surfaces of fluorotic teeth were studied by scanning electron stereomicroscopy. Different whitening treatments were applied to 25 pieces to remove stains caused by fluorosis and their surfaces were characterized by stereomicroscopy in order to obtain functional and amplitude parameters.
