Journal of Applied Oral Science, Bauru, v. 18, n. 5, p. 467-476, Sept./Oct. 2010.1678-7757http://repositorio.bc.ufg.br/handle/ri/19044In the most recent decades, several developments have been made on impression materials’ composition, but there are very few radiodensity studies in the literature. It is expected that an acceptable degree of radiodensity would enable the detection of small fragments left inside gingival sulcus or root canals. Objective: The aim of this study was to determine the radiodensity of different impression materials, and to compare them to human and bovine enamel and dentin.engAcesso AbertoRadiographyBovine toothDental impression materialsHuman toothEnamelDentinArtigo10.1590/S1678-77572010000500007
