The Most Prevalent Shade of Anterior Teeth Among Egyptians Attending the MIU Dental Clinic: A Cross-sectional Observational Study
Objectives: The purpose of this study was to was designed to identify the most frequent tooth colors among a sample of Egyptian participants who receive their treatment in Misr university outpatient clinic analyzing different age and gender groups, according 3D Master System
Methods: A convenience sample of 180 subjects was recruited at Misr international university outpatient dental clinic into three equal groups according to age: young group (18-30 years old) (n=60), middle age group (31-59 years old) (n=60) and elderly group over 60 years old) (n=60). Each group will be further subdivided equally into two equal subgroup according to gender (male /female) (n=30 each). Color recording was carried using a spectrophotometer (Easyshade Compact; Vita Zahnfabrik) with a standardized protocol for color evaluation. Chi-square and spearman’s correlation coefficient was used to determine the significant correlations. The significance level was set at p< 0.05.
Results: The most prevalent shade of all teeth was 2M2 (20.6%) followed by 3M3 (13.0%) then 2M3 (11.2%). The least prevalent shade was 3R3.5 (0.1%) followed by 3R1.5 (0.2%) then 4L2.5 (0.3%). As regards the upper canine (n = 360); the most prevalent shade was 3M3 (23.1%) followed by 2M3 (14.7%) then 3M2 (11.7%). The least prevalent shades were 2R1.5, 3R1.5, 3R3.5 and 4L2.5with a prevalence of (0.3%) for each shade. Shades 1M1, 1M2, 2L1.5 and 2L2.5 were not found.
While for upper lateral incisor teeth (n = 360); the most prevalent shade was 2M2 (28.9%) followed by 2M3 (8.9%) then 3M2 (8.1%). The least prevalent shades were 2R1.5, 3R1.5, 3R3.5 and 4L2.5with a prevalence of (0.3%) for each shade. Shades 1M1, 1M2, 2L1.5 and 2L2.5 were not found.
As regards the upper central incisor teeth (n = 360); the most prevalent shade was 2M2 (30.0%) followed by 2M3 (10.0%) then 3M3 (8.3%). The least prevalent shades were 3M1, 3R1.5 and 5M1 with a prevalence of (0.3%) for each shade. Shades 3R3.5, 4L2.5, 4R1.5, 5M2 and 5M3 were not found.

Conclusions: The most prevalent shade of all teeth was 2M2 , the Shade prevalence is effect by tooth position
