Effects of eye dominance on shade matching and color perception among the dentist population.

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 ( = 40); Group II: postgraduates ( = 34); Group III: senior residents and faculty members (≥ 6 years of clinical experience) ( = 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.
