Evaluation of the Effectiveness of Different Intraoral Scanners in Shade Selection

Aim: The aim of this study was to investigate the

efficacy and repeatability of different intraoral scanners for in vitro shade

selection.<o:p></o:p>

Materials and Methods: Three intraoral scanners (Trios

5, Primescan, Medit i700) and two shade guides (Vita Classic, Vita 3D Master)

were used in this study. Measurements from the intraoral scanners were compared

with those from a spectrophotometer. The Vita Classic shade guide contains 16

samples, while the Vita 3D Master shade guide contains 26 samples, giving a

total of 42 samples. Analyses of the accuracy, precision and trueness of the

values obtained were carried out. Statistical analyses of the data were

performed using independent samples T-test and parametric one-way ANOVA tests<o:p></o:p>

Results: As a result of the analyses performed, it was

determined that the Trios 5 device had the highest accuracy rate (%75) in the

Vita Classic color guide, while the Primescan device had the highest accuracy

rate (%84.62) in the Vita 3D Master color guide. The Trios 5 also performed

best on the Vita Classic color guide, with the lowest trueness value (0.25). In

contrast, the Primescan device performed best on the Vita 3D Master color gamut

with the lowest trueness value (0.15). Standard deviation analyses showed that

the Trios 5 device provided higher trueness for some measurements, while the

Primescan and Medit i700 devices showed similar levels of trueness.<o:p></o:p>

Conclusion: When comparing the devices, the Primescan

device can be considered the best scanner overall due to its high accuracy

(%84.62) and low trueness value (0.15) in the Vita 3D Master, as well as its

consistency in terms of repeatability. The Trios 5, on the other hand, is the

scanner with the best performance (%75) in the Vita Classic color scale.<o:p></o:p>
