Abstract: 
Introduction: Due to importance of color determination in the success of cosmetic treatments, we decide to evaluate the prevalence of lateral maxillary incisor color with different systems and compare results with each other, by the hypothesis that there is no difference between the color determination of prosthodontist, dental technician and dental student. Materials & Methods: This cross-sectional study was performed in 2016 on the maxillary lateral teeth of 120 patients came to Kermanshah dental school aged between 20-30 years. The teeth color of each patient was reported by three observers using Vita classic, 3D-master color samples and finally spectrophotometer. Then parameters L, a, b and Δ E were calculated for each patient. Data were analyzed by the use of SPSS 16 with Friedman (α = 0. 05) and Wilcoxon (α = 0. 017) statistical tests. Results: The most common color observed in the Vita classic was A2 (25. 83%) and in the 3Dmaster color sample was 2R2. 5 (21. 67%). The calculated Δ E of the prosthodontist in Vita classic color samples was less than the other observers (p value < 0. 001). In 3D-master, Δ E of dental technician was lower than dental student (p value = 0. 016). In other cases, the difference was not significant. Conclusion: The most common tooth color in the study population with Vita classic was A2 and with 3D-master was 2R2. 5. The accuracy of color determination by prosthodontist in Vita classic was higher than of the technician and the student. In 3D-master, dental technician was more precise than the student.
