Radiopacity significantly differs between additively manufactured resins and conventional composites, with temporary resins showing the lowest values. Thicker materials increase radiopacity, impacting radiographic diagnosis and material selection.

Area of Science:

  • Dental Materials Science
  • Radiology
  • Biomaterials Engineering

Background:

  • Radiopacity is a critical property for detecting secondary caries and evaluating restoration integrity.
  • Additive manufacturing (AM) offers novel restorative materials, but their radiographic properties require evaluation.

Purpose of the Study:

  • To compare radiopacity of additively manufactured permanent and temporary resins against conventional resin-based composites.
  • To assess the influence of material thickness on radiopacity.

Main Methods:

  • Eight dental materials (AM permanent/temporary resins, conventional composites) were tested at 1mm and 2mm thicknesses.
  • Radiopacity was measured in mmAl using digital radiography and compared to tooth structure and an aluminum wedge.
  • Statistical analysis included Kruskal-Wallis, Dunn-Bonferroni, and Mann-Whitney U tests (α=0.05).

Main Results:

  • Significant differences in radiopacity were found among all material groups (p<0.05).
  • Conventional resin-based composites exhibited the highest radiopacity, while AM temporary resins showed the lowest.
  • Increasing thickness from 1mm to 2mm significantly increased radiopacity for all materials (p<0.001).

Conclusions:

  • Radiopacity varies considerably among dental restorative materials, influenced by composition and thickness.
  • Some AM temporary resins possess radiopacity lower than natural tooth structures, potentially hindering radiographic detection.
  • Careful material selection is crucial for accurate radiographic diagnosis and monitoring of restorations.
