Summary

Glass ionomer cements offer moderate radiographic obscuration for titanium posts, unlike resin cements. Further research is needed to recommend optimal luting materials for titanium alloy posts in endodontics.

Area of Science:

  • Dental Materials Science
  • Endodontics
  • Radiology

Background:

  • Titanium alloy prefabricated posts are widely used in endodontic restorations.
  • The radiographic visibility of these posts is crucial for post-treatment assessment.
  • Luting material selection can influence the radiographic appearance of posts.

Purpose of the Study:

  • To compare the radiographic obscuration of eight luting materials when used with titanium alloy prefabricated posts.
  • To evaluate the impact of different luting agents on the visualization of cemented posts in endodontically treated teeth.

Main Methods:

  • Eight endodontically treated maxillary molar teeth were used.
  • Titanium alloy posts were cemented into prepared post channels using eight different luting materials.

  • Preoperative, precementation, and postcementation radiographs were taken and visually assessed for post outline visibility.

    • Main Results:

    • Glass ionomer cements showed moderate obscuration of the titanium post outline.
    • Composite resin cements exhibited less obscuration compared to glass ionomers.
    • Zinc phosphate and polycarboxylate cements resulted in the most significant obscuration of the post outline.

    Conclusions:

    • Luting material choice significantly affects the radiographic visibility of titanium alloy posts.
    • Glass ionomer cements provide a balance between obscuration and visibility.
    • Further investigation is required to establish definitive recommendations for luting materials with titanium posts.
