The aim of this study was to evaluate the prevalence and awareness levels of color
blindness among students in a faculty of dentistry and dental prosthesis technology
program in two different universities.
Materials and Methods
A survey of awareness of color blindness among 710 students (males: n=271; females:
n=439) in the faculty of dentistry and dental prosthesis technology program of Gazi
University and Ankara Medipol University in 2019–2021 was conducted. The color
vision status of 442 of the students (males; n=155; females: n=287) was assessed
using an online Ishihara color blindness test. The data obtained were subjected to
statistical analysis using SPSS.
There was no statistically significant difference in the color blindness scores in
terms of sex (males: 0.75±0.84; females: 0.64±0.75) (p=0.226). The color blindness
scores of the dental prosthesis technology students were statistically higher than
those of the faculty of dentistry students (p=0.028). Education year was significantly
associated with a compromised ability to identify colors properly (p=0.040). There
was no statistically significant difference in terms of awareness levels of color
blindness according to the number of years of education (p>0.005).
In terms of the prevalence of color blindness, 2.2% of faculty of dentistry and dental
prosthesis technology students had a moderate-to-high level of color blindness.
Students' awareness of their own color vision status was very low. The educational
content of faculty of dentistry and dental prosthesis technology programs on color
blindness should be enriched.
