 note = {P(論文), The RMS graininess of four kinds of Kodak dental x-ray films were measured as a function of density on various tube voltages:Ultraspeed and Ektaspeed dental x-ray films for periapical radiography (ULTRA and EKTA dental), and Ultraspeed and Ektaspeed dental x-ray film Ready Packs for panagraphy (ULTRA and EKTA panagraphy). The RMS graininess curve of ULTRA dental was similar to ULTRA panagraphy for all tube voltages. It was also the same for EKTA dental and panagraphy films. The RMS graininess of the ULTRA films was dependent on the tube voltage, but this was not the case for the EKTA films. The maximum value of the RMS graininess curve at each measured tube voltage was nearly constant, while the density decreased with increasing tube voltage.},
