This in vivo study aimed to evaluate this function in relation to visual and spectrophotometric shade determination. Materials and Methods: Ten dental students from Semmelweis University determined tooth shade for 10 volunteers using Vita A1-D4 (VC) and Vita Linearguide 3D-Master (LG) guides, Vita Easyshade spectrophotometer (ES) and Trios 3 intraoral scanner (TR). First and last patient was always the same (Patient R). Intrapersonal repeatability was calculated. Four selected shades of each tooth were presented to student, supervisor, and patient to select best match. Selection percentages were calculated. The supervisor's best match was the reference (∆E00). Results: Median ∆E00 of Patient R: TR 1.09; VC 1.5; ES 2.35; LG 3.1. The percentages of best match: VC 16.7%.; TR 21.64%; ES 26.58%; LG 34.08%. Median ∆E00 of students' and supervisor's best match: LG 2.73; ES 4.29; TR 4.29; VC 16.35. TR was the most repeatable. The most “best-match shade tabs” were selected using LG. VC shade tabs was the least consistent with the examined teeth. Conclusions: TR can be used for shade selection with a 3D-Master tooth color system with visual verification. Clinical Significance: Correct tooth shade determination is one of the most important step in making esthetic restorations. New shade matching systems have been developed to surpass the visual method of shade determination. There are new intraoral scanners with built-in shade measurement functions. Digital shade determination methods are more independent from the environmental circumstances, and with intraoral scanners, it is easy to measure the tooth shade by taking a digital impression at the same time. These new devices may be a reliable alternative method for shade selection with visual verification. © 2021 The Authors.

MATERIALS AND METHODS: The spectral radiance of 63 monochromatic ceramic specimens was determined using a non-contact spectroradiometer. A total of 60 specimen pairs, divided into 3 sets of 20 specimen pairs (medium to light shades, medium to dark shades, and dark shades), were selected for psychophysical experiment. The coordinating center and seven research sites obtained the Institutional Review Board (IRB) approvals prior the beginning of the experiment. Each research site had 25 observers, divided into five groups of five observers: dentists-D, dental students-S, dental auxiliaries-A, dental technicians-T, and lay persons-L. There were 35 observers per group (five observers per group at each site x7 sites), for a total of 175 observers. Visual color comparisons were performed using a viewing booth. Takagi-Sugeno-Kang (TSK) fuzzy approximation was used for fitting the data points. The 50:50% PT and 50:50% AT were determined in CIELAB and CIEDE2000. The t-test was used to evaluate the statistical significance in thresholds differences. RESULTS: The CIELAB 50:50% PT was DeltaEab = 1.2, whereas 50:50% AT was DeltaEab = 2.7. Corresponding CIEDE2000 (DeltaE00 ) values were 0.8 and 1.8, respectively. 50:50% PT by the observer group revealed differences among groups D, A, T, and L as compared with 50:50% PT for all observers. The 50:50% AT for all observers was statistically different than 50:50% AT in groups T and L. CONCLUSION: A 50:50% perceptibility and ATs were significantly different. The same is true for differences between two color difference formulas DeltaE00 /DeltaEab . Observer groups and sites showed high level of statistical difference in all thresholds. CLINICAL SIGNIFICANCE: Visual color difference thresholds can serve as a quality control tool to guide the selection of esthetic dental materials, evaluate clinical performance, and interpret visual and instrumental findings in clinical dentistry, dental research, and subsequent standardization. The importance of quality control in dentistry is reinforced by increased esthetic demands of patients and dental professionals.

JF - JOURNAL OF DENTISTRY J2 - J DENTISTRY VL - 37 PY - 2009 IS - SUPPL. 1 SP - e40 EP - e44 SN - 0300-5712 DO - 10.1016/j.jdent.2009.05.012 UR - https://m2.mtmt.hu/api/publication/1466540 ID - 1466540 AB - Objectives: To evaluate the influence of gender and level of experience on shade matching quality. Methods: A study was simultaneously performed at 15 universities located in 9 countries. A total of 614 color normal participants completed all phases of the experiment. Among them, there were 305 females and 309 males, 319 dental students and 295 dental professionals. A lecture on color matching in dentistry was given to all participants. Initial training was performed using Toothguide Trainer software (TT), while Toothguide Training Box (TTB) was used for both training and testing of participants' shade matching results. The test task was to successively match 15 shade guide tabs with the corresponding shade guide. The shade matching score for each participant was computed as a sum of color differences (∑ Δ Eab* score) between target tabs and selected tabs. Lower scores corresponded to better shade matching results and vice versa. Means and standard deviations were calculated. Mann-Whitney U test was used for statistical analysis of the data (α = 0.05). Results: The mean shade matching score (S.D.) for all participants was 41 (21). The score for female and male participants was 38 (20) and 44 (21), respectfully (p < 0.001). The difference in scores between dental students, 42 (20), and dental professionals, 39 (21), was not statistically significant. Conclusion: Within the limitations of this study, females achieved significantly better shade matching results than males, indicating that gender plays an important role in shade matching. The level of experience was not found to be significant factor in shade matching. © 2009 Elsevier Ltd. LA - English DB - MTMT ER -
