Summary
Radiopaque denture liner material containing barium sulfate offers excellent visibility on X-rays. This material, nearly as radiopaque as aluminum, aids in noninvasive detection and radiographic identification of dental prosthetics.
Area of Science:
- Biomaterials Science
- Radiology
- Dental Materials
Background:
- Polymeric biomaterials require radiopacity for effective noninvasive detection.
- Current materials may lack sufficient radiopacity for clear radiographic identification.
Purpose of the Study:
- To evaluate the radiopacity of a permanent denture liner material.
- To determine its suitability for radiographic identification.
Main Methods:
- Incorporation of barium sulfate filler into a permanent denture liner material.
- Radiopacity assessment compared to aluminum standards.
Main Results:
- The barium sulfate-filled denture liner material demonstrated radiopacity comparable to aluminum.
- Optimal radiographic observation was noted for material thicknesses between 1 mm and 3 mm.
Conclusions:
- Permanent denture liner materials with barium sulfate filler are highly radiopaque.
- This material is suitable for radiographic identification in dental applications.
