This laboratory study found that provisional cement type was the main determinant of color and translucency changes in DLP-printed provisional restorations. Translucent resin-based cement produced the smallest changes, whereas zinc oxide non-eugenol cement produced the largest color deviation, especially at greater film thickness.
Key findings
- Cement type and film thickness significantly affected ΔE00 (p
Why this matters globally
The study addresses esthetic control in digital dentistry and can inform material selection hypotheses and future clinical testing of CAD/CAM and 3D-printed provisional restorations.
Thai researcher contribution
The study was conducted by researchers from the Faculty of Dentistry, Naresuan University, demonstrating Thai expertise in dental materials, 3D printing, and quantitative color assessment.
Limitations to consider
This was an in-vitro disk-specimen study. It did not reproduce crown geometry, saliva, occlusal loading, ageing, or patient-perceived color, so clinical outcomes and long-term superiority cannot be inferred.
