“…The inability to determine clinical signs based on color and shade is disadvantageous in aesthetic restorative dentistry. 5 The clinical errors made by those with CVD are higher than those with normal color vision. Dentists with red-green color vision deficiency find it challenging to determine the color due to lighting conditions and color temperature.…”

Objective The current research was conducted to evaluate the frequency of color-vision deficiency among dental students of King Khalid University College of Dentistry, Saudi Arabia. Materials and Methods A cross-sectional study was performed among 203 dental students working as interns at male and female dental clinics of King Khalid University College of Dentistry (KKUCOD), Saudi Arabia. The Ishihara color-vision deficiency (CVD) test with 24 plates was used for diagnosis of the problem. Analysis of the data was done by performing Chi-square tests using SPSS software version 20. Results The frequency of total CVD was found to be 3.9%. While the association of gender with total CVD was observed to be statistically nonsignificant, a statistically significant relation was drawn with red-green color deficiency. Out of the total of 203 patients, 44 males were identified with red-green color deficiency, whereas only three females were found to have this condition, therefore revealing that CVD is more prevalent in males. Age was found to have a significant association with red-green color vision deficiency, protanopia, and total CVD. Conclusion A total of 20.19% male dental students had red-green color vision deficiency compared to 1.4% in female students. The dental students must be aware of their congenital color vision deficiency and its impact on their professional life. Screening of such dental students and professionals is quite important so that they can tackle the color vision problems well without having detrimental effect on their future dental practice.

Visual impairment due to refractive errors and color vision deficiency (CVD) can affect the visual abilities of workers in workplace. Identifying the prevalence of common visual problems helps us to prevent and treat occupational ocular problems.This study was conducted on 2600 males referring from companies for a routine medical exam to Occupational Medicine Center. In all subjects, visual acuity and refraction were measured. Assessment of color vision was performed by Ishihara color test. In present study, right eyes of subjects were selected to statistical analysis.The mean spherical equivalent was –0.19 ± 1.39 diopter with a range of –11.00 to +10.00 diopter. Whereas 71% of persons were emmetropic, 20% and 9% of them were myopic and hypermetropic, respectively. From a total subjects, 164 of them had CVD with prevalence of color blindness of 6.3%. In comparison with normal subjects, CVD had no significant effect on refractive findings of our subjects (P > .05).Our data present the prevalence of refractive errors and color blindness among Iranian industry-workers. Compared with other studies, our subjects have a lower prevalence of refractive errors, and similar rate of prevalence of color blindness.

En un tratamiento de rehabilitación estético exitoso se consideran la forma, textura y color, en este último la selección puede verse afectada por factores como la discromatopsia que ocasiona un error de apreciación cromática. Objetivo: Determinar la relación entre la discromatopsia presente en estudiantes de odontología y la capacidad de discriminación durante la toma de color dental. Metodología: estudio observacional en 308 estudiantes de los últimos semestres de la Facultad de Odontología de la Universidad Central del Ecuador, mediante el test de Ishihara se diagnosticó a 18 discrómatas que conformaron el grupo de estudio, en igual número se conformó el grupo control con estudiantes tricrómatas sin déficit de agudeza visual. La valoración de la apreciación cromática dental se realizó mediante seis evaluaciones de valor, matiz y saturación en colorímetros Vita 3D Master Toothguide y Linearguide. Se utilizó T de Student para comparar los datos cuantitativos; y finalmente la correlación de Pearson para determinar la asociación de dos variables. Resultados: se encontró que existe variación estadísticamente significativa en el desempeño de las evaluaciones realizadas entre los grupos discrómatas y tricrómatas (p= 0,014). En la comparación de los errores por los participantes en la dimensión de color se determinó en la dimensión Valor un p 0,047. Se obtuvo una correlación de 0,615. Conclusión: La discromatopsia disminuye el poder de discriminación durante la toma de color dental en el Valor. Existe una correlación moderada entre los grupos de estudio.
