J Xray Sci Technol
. 2011 Feb;
4(2):102-17.
PMID: 21307458
In scanning microradiography (SMR), a thin section is stepped across a 15-μm diameter X-ray beam and the transmitted intensity measured at each point. This technique has permitted more accurate measurements...

. 2000 Nov;
38(1-4):61-72; discussion 73-9.
PMID: 11063016
The mineral content of dental enamel is commonly measured by X-ray attenuation experiments. Most studies have used contact microradiography in which intensities are measured with photographic film which is convenient...

34(2):164-74.
PMID: 10773635
The application of non-contact optical profilometry for non-destructive study of changes in the surface roughness of natural enamel surfaces during in vitro demineralization was investigated. Repeated measurement of profiles of...
