Background and Aims: Achieving reliable tools for accurate shade matching of ceramic samples is of great importance in restorative and aesthetic dentistry. This study aimed to evaluate the accuracy of the Trios5 intraoral scanner in determining the shade of ceramic samples using the Vita Classical Shade Guide (VC).
Materials and Methods: This in-vitro study involved scanning each ceramic sample 15 times by two independent observers using the Trios5 intraoral scanner. The detected shade of each sample was compared with the reference shades of the Vita Classical Shade Guide (VC) and the compatibility of the scanner’s results with the reference shades was assessed. The data were analyzed using SPSS24 software and Pearson correlation and paired t-tests and kappa coefficient at a significance level of 0.05.
Results: The highest accuracy of shade detection in both observers was found for shades A2, A3, A3.5, A4, B1, and C4, each with 100% accuracy. The lowest accuracy for both observers was noted for shade A1, with 0% accuracy. The mean overall accuracy for the first and second observers was 64.99% and 63.75%, respectively, with a total overall accuracy of 64.37%. A statistically significant interobserver agreement was observed (P≤0.005).for all shades except B2 (P=0.299).
Conclusion: The Trios5 intraoral scanner can be considered a useful adjunct tool for ceramic shade determination. However, for clinical applications, it is recommended to use it in conjunction with reference tools and complementary methods such as spectrophotometry or visual assessment by experienced clinicians.
