Rectangular specimens (5\u2009\u00d7\u20095\u2009mm) were fabricated at two standardized thicknesses (1 and 2\u2009mm) (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200910). Extracted human tooth sections and a 21\u2010step aluminum wedge were used as reference standards. Radiographic images were obtained using a digital intraoral radiography system, and radiopacity values were measured in mmAl using ImageJ software. Statistical analysis was performed using Kruskal\u2013Wallis, Dunn\u2013Bonferroni, and Mann\u2013Whitney\n                      <jats:italic>U<\/jats:italic>\n                      tests (\n                      <jats:italic>\u03b1<\/jats:italic>\n                      \u2009=\u20090.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Significant differences in radiopacity were observed among the tested materials (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). Additively manufactured temporary resins demonstrated the lowest radiopacity values, whereas conventional resin\u2010based composites exhibited the highest radiopacity. Permanent additively manufactured resins showed intermediate radiopacity values. Increasing specimen thickness from 1 to 2\u2009mm significantly increased radiopacity values for all materials (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
