“…Around 30 years of age due to a change in the absorption of light by the ocular apparatus there is a gradual reduction in pupil size and color perception, but it does not manifest itself until the sixth decade of life [ 1 15 ]. If an older population of dental professionals were studied, the physiological impact of age may be overlooked due to the years of dental shade-matching experience.…”

“…Clinically, the success of a restoration is decided by numerous factors, but it is truly accomplished by the patient’s acceptance. More than 80% of patients were reported to be aware of the shade mismatch with an anterior metal-ceramic restoration to the adjacent natural tooth [ 1 ]. This fact reveals the significance of shade selection in an esthetic restorative procedure.…”

Objectives The purpose of this study was to evaluate the influence of eye dominance on color perception, and shade matching. Materials and Methods A total of 104 participants were selected for the study. There were 3 groups: Group I: 3rd and 4th year dental students and interns ( n = 40); Group II: postgraduates ( n = 34); Group III: senior residents and faculty members (≥ 6 years of clinical experience) ( n = 30). All participants were evaluated for congenital color blindness with Ishihara plates, their dominant eye with Mile's test, and their color perception with the Farnsworth-Munsell 100 hue test. The shade guide test was used for shade matching with a second corresponding set of Vitapan classical shade guides. Results The results of Mile’s test revealed that 60.6% were right-eye dominant and 39.4% were left-eye dominant. There was a statistically significant difference among all participants between the dominant eye and the non-dominant eye in shade matching. Conclusions The dominant eye has a positive effect on shade matching and the ability to match shades becomes better with an increase in clinical experience.

“…En la literatura se debate frecuentemente sobre el género y la experiencia. Algunos trabajos comentan que ambos no son significativos (24) y afirman que el género no influencia la evaluación del color (25,26); por el contrario, hay investigaciones que aseveran que las mujeres tienen mayor precisión en la evaluación visual del color (15,26,27); otros autores señalan que la experiencia sí es significativa (28). Por todo lo anterior, se necesita mayor evidencia para llegar a una conclusión.…”

“…Sobre el género y la experiencia, son diversas las diferencias que se encuentran en la literatura. Algunos autores afirman que el género no influye en la precisión para la toma de color (24,26); por el contrario, otras investigaciones mencionan que las mujeres son más precisas que los hombres (15). También, existen estudios que comparan los efectos de la nivelación en la selección de color obteniendo buenos resultados, pero indican que estos deben ser practicados metódicamente (17)(18)(19)(20).…”

Objetivo: establecer los parámetros para la evaluación visual e instrumental del color dental en estudios in-vitro a partir de la literatura científica publicada entre 2015 y 2021. Métodos: se realizó la búsqueda en las bases de datos: PubMed, Web of Science, Science Direct, Scopus, Scielo y Lilacs; también en el motor de búsqueda Google Académico y las bibliotecas de las editoriales Wiley y Springer. Las palabras clave utilizadas fueron tooth, color, in-vitro, color perception, shade matching, thresholds, appearance, surrounding, “CIELAB” y “CIEDE2000”. Teniendo en cuenta los criterios de elegibilidad, se seleccionaron los estudios de acuerdo al título, resumen y texto completo. Resultados: la búsqueda arrojó un total de 37 publicaciones que se agruparon en tres tópicos: 1. toma de color visual: condiciones ambientales, observadores y nivelación; 2. toma de color instrumental: instrumentos; y 3. procesamiento de datos: cálculo de la diferencia de color y umbrales de perceptibilidad (PT) y aceptabilidad (AT). Conclusiones: los aspectos más importantes en la evaluación visual son la iluminación, el ambiente para registro (sitio, entorno y fondo alrededor de la muestra), las condiciones geométricas de visualización, los observadores y el uso de guías. En la evaluación instrumental es relevante elegir el aparato apropiado de acuerdo con su precisión y reproducibilidad, como los espectroradiómetros y los espectrofotómetros de uso clínico. Se presenta el procesamiento de datos para establecer las variaciones de cada coordenada, las diferencias de color (ΔE): CIELAB y CIEDE2000, los umbrales y los lineamientos.

BACKGROUND: Dentists must be able to identify subtle color changes as shade-matching is crucial in aesthetic dentistry. OBJECTIVE: To determine whether color discrimination ability is related to shade-matching accuracy among dentists. METHODS: The sensitivity of the normal-color vision population to different colors was investigated using Farnsworth Munsell 100 Hue (FM-100) test results. The FM-100 test was administered to 37 dentists at the Hospital of Stomatology, Jilin University. Sensitivity of dentists with normal-color vision to different colors was investigated using the FM-100 test. Participants were instructed to arrange color caps of various colors according to the gradual change in colors and the results were scored. Visual shade matching test using Vita 3D-MASTER shade guide was performed to determine shade-matching accuracy. The relationship between color discrimination ability and shade-matching accuracy was analyzed. The number of misplaced color caps in the FM-100 test was also calculated. RESULTS: The FM-100 test revealed that 16 and 21 participants had excellent and average color discrimination ability, respectively, and their shade-matching accuracies were 68.75% and 66.67%, respectively. No significant difference was observed in the shade-matching accuracy between the two groups. No significant correlation was observed between the color discrimination ability and shade-matching accuracy. In addition, the number of wrong color caps on the 43–63 color tray with the transition from blue-green to blue-purple was the highest according to Friedman’s test. CONCLUSION: Color discrimination ability of dentists does not affect their visual shade-matching accuracy. Additionally, people with normal color vision are not sensitive to the transition from blue-green to blue-purple.
