microradiography

(mī´krōrād´ēog´rəfē),
n a process by which a radiograph of a small or very thin object is produced on fine-grained photographic film under conditions that permit subsequent microscopic examination or enlargement of the radiograph within the resolution limits of the photographic emulsion, which approaches 1000 lines/mm.

Contact x-ray microradiography is the primary tool used by researchers to evaluate the mineral density of dental hard tissues [1], This "gold standard" is particularly important as research regarding changes in mineral density is critical to understanding and preventing (or reversing) human caries: the most prevalent curable disease worldwide [2].
Ultimately, x-ray microradiography is the only current method that determines mineral density directly (via attenuation of x-ray energy by the mineral), and as such it has long been known as the "gold standard" for mineral density measurements [1, 3-7, 10].
However, the x-ray sensitive film previously used for contact microradiography has been discontinued and has been out of production for several years.
Overall, VRP-M film was found well-suited to the needs of x-ray microradiography and will likely serve as the film of choice until digital x-ray detectors reach a spectral resolution acceptable for research use.
