Purpose: To identify the most frequent natural tooth color using the Easy shade Micro spectrophotometer on a sample of the Moroccan population according to the 3D Master System. Materials and Methods: The middle third of the facial surface of natural maxillary central incisors was measured with an Easy shade Micro spectrophotometer in 1100 Moroccan participants aged between 16 and 89 years. Natural tooth color was recorded using the 3D Master System nomenclature. The program used for the results descriptive statistical analysis was SPSS. Results: The results show that the most frequent dental color in the total sample studied is 2R2.5 (25.7%), followed by the shade 1M2 (23.2%) and 2M2 (14.1%). Conclusion: According to the research methodology used, and taking into account the limitations of this study, it can be proposed that the most frequent color among the Moroccan population is 2R2.5; the most common value group is 2; the most frequent hue group according to the 3D Master System is M and the most frequent chroma group is 2.
