 Objectives: The aim of this study was to evaluate the effect of clinical experience level on the shade matching accuracy in different dental occupational groups. Materials and methods: A total of 80 participants, assigned to one of four groups depending on the level of their clinical experience in shade matching: dental technicians (DTs), residents in prosthodontics (RPs), specialists in prosthodontics (SPs) and dental students (DSs) took part in the study. They were asked to use Tooth guide Training Box (TTB) and determine 15 standardized shade tabs using VITA 3D-Master shade guide. The number of mistakes in final test for each participant was recorded and accuracy was calculated. Color difference (ĆE) values for each shade were calculated from L*, a* and b* values. Differences in accuracy, mean ĆE values and mean error ĆE values between four different groups were examined. Results: No statistically significant differences were found between the groups regarding accuracy and mean ĆE values (p > 0.05). The accuracy rate in four groups was 0.51±0.20 (DTs), 0,54±0.18 (RPs), 0.49±0.16 (SPs) and 0.55±0.14 (DSs), respectively. Mean ĆE values were 2.10±0.98 (DTs), 2.18±0.97 (RPs), 2.51±0.97 (SPs) and 2.08±0.86 (DSs), respectively. Regarding mean error ĆE values, DTs made errors with significantly less deviations compared to other groups (p < 0.05). Conclusions: This study has shown that clinical experience is not found to be a significant factor to the shade matching accuracy. With regard to the mean error ĆE values, DTs were more successful in shade matching than other participants. © University of Zagreb.
