Radiopacity and microhardness changes and effect of X-ray operating voltage in resin-based materials before and after the expiration date

This study observed alteration in the radiopacity and microhardness of expired resin-based materials compared to non-expired materials and the operating characteristics of the X-ray source used. Five 2 mm-thick cured specimens were prepared for each material: composite resins (P60®, Z100®), and a co...
