“…Thus, older observers could present an alteration in color perception 1 . The influence of gender on visual perception is controversial, some studies reported better performance for males, 10,11 others reported better performance for females 8,12‐14 .

“…Most dental studies on color perception have used the Ishihara (I) test as a pretest for observers recruiting 7,8,11‐13,17‐21 . The Farnsworth‐Munsell 100 Hue test 10,14,15,22,23 and the color correspondence test using dental shade guides (eg, VITA Classical) 6,14 have been also used. The latter is also known as the test for color discrimination competency in dentistry and it is recommended by the ISO 24…”

Objective To evaluate the efficacy of visual discrimination tests used for color research in dentistry. Materials and methods Volunteers (N = 120) were divided in three groups of observers (n = 40; gender‐balanced): S‐dental students; D‐dentists; and L‐laypersons. Two general color discrimination tests (I‐Ishihara and FM‐Farnsworth‐Munsell 100 Hue) and the test of color discrimination competency in dentistry using the VITA Classical shade guide (VC) were performed and data were recorded according to manufacturers' or literature recommendations. Data were statistically analyzed using Mann–Whitney U test for the gender influence and Kruskal‐Wallis test for the observer influence, and Bonferroni as post‐hoc test (α = 0.05). Pearson (α = 0.05) was used to examine the correlation among visual tests (I, FM, and VC). Results Observers and visual tests were not influenced by gender (P > .05). Different observer groups had no influence on I test (P > .05). S and D showed similar level of color perception using FM and VC (P > .05), but these observers showed greater color perception than L (P ≤ .05). FM and VC also showed significant correlation (P ≤ .05) for the overall D observers (r = −0.362), male D (r = −0.594) and female S (r = −0.457). Conclusion Observer experience significantly influenced on color perception, irrespective of gender. FM test showed greater correlation to color correspondence in dentistry (VC) than I test. Clinical significance Observer experience is more relevant than gender for the color selection process in dentistry. Considering the visual discrimination tests for color research in dentistry, the Farnsworth‐Munsell 100 Hue test seems to be more efficacious than the Ishihara test.

“…The Dental Color Matcher is a free online education and training program available from the Society for Color and Appearance in Dentistry 23 . The best and least expensive exercise may be the practice of matching together pairs of masked shade tabs from two exact shade guides 16,24 . Benefits of training include enhance esthetic restorative dentistry, resulting in improved patient satisfaction that will boost the patient's confidence in the provider l .…”

“…The Perceptual Ability Test (PAT) is a component of the DAT that is used to ascertain an applicant's spatial visualization skills. There is recent evidence suggesting that it may be useful in screening for the presence of CVD and the ability to match dental shades 16 . The purpose of this study was to determine if there is an association between the PAT and the presence of CVD in first‐year dental students.…”

Objective: The purpose of this study was to determine if there is an association between Perceptual Ability Test (PAT) results and color vision deficiency (CVD). Methods: Three consecutive classes of first-year dental students (n = 291) voluntarily participated in the study. The Farnsworth-Munsell 100 Hue Color Vision test (FM-100) was administered to students beneath a Macbeth Judge II viewing booth that provided ideal lighting conditions to ascertain CVD. Results of FM-100 test were recorded as total error scores (TES). Color acuity was scored as superior (TES 0-16), average (TES 20-100), or poor (TES > 100). Additional information of age, sex, ethnicity, and time to complete the FM-100 was obtained. Multiple linear regression was used to determine the association between PAT and CVD while adjusting for age, sex, ethnicity, and time to complete the FM-100 test. Results: TES ranged from 0-244. There were 132 students with superior color acuity, 161 with average, and eight with poor acuity. Females performed better than males on the FM-100 test. Time to complete the FM-100 test ranged from 3:40 minutes to 25:12 minutes. There was a strong relationship between PAT scores and CVD (P = 0.0003). A 1-unit increase in PAT scores was found to result in a 9% decrease in TES; indicating that students with higher PAT scores are less likely to have CVD. Conclusion: The PAT may be a preliminary screening instrument to identify students who may have CVD. The FM-100 test can then confirm the presence of CVD. Students with CVD may desire to improve dental shade matching skills through targeted training and education.
