“…The light source is a critical component that contributes to the perception of color. There were only 4 studies that did not specify the light source, of which 2 reported significantly better female performance 52,56 and 2 found no significant difference. 37,38 All the other 33 studies specified the source as daylight, artificial light, or a combination of these two (Table 2 details light parameters of individual studies).…”

“…Furthermore, some studies used multiple guides, for example, when the primary research question dealt with the effects of the guide selection on the individual performance. There were 12 studies that used the Vita classic shade guides, 5 of which reported significantly better performance of females [49][50][51][52]54 and 7 reported no significant difference, 1,5,19,42,44,45,47 Vita 3D Master was used by 12 studies, of which 4 reported significantly better performance of females 18,53,56,57 and 8 reported no significant difference. 9,14,17,[32][33][34]36,46 Two studies used Vita linear guide 3D Master, both reporting no significant difference.…”

Objectives: To evaluate systematically the influence of sex of dental professionals on their capability for visual color matching. Materials and Methods:The protocol was registered on PROSPERO (CRD42020205393). PICOS question was develop based on the population, intervention, comparison, outcomes, and study design (PICOS). Eligibility criteria included cross section studies, randomized clinical trials and cohort studies that compared the effect of sex on the visual color matching process. Five electronic databases (Pubmed, Cochrane, EMBASE, Medline, and SCOPUS) and additional literature were screened independently by two researchers in July 2020. Clinical studies evaluating visual color matching skills of dental professionals were included. Studies that did not compare the difference between sexes were excluded. Duplicate articles were removed, titles and abstracts were screened, and studies were selected according to the inclusion criteria. Data were collected and reported in accordance with PRISMA guidelines. Risk of bias was assessed using Joanna Briggs Institute Critical Appraisal Tools.Results: A total of 1192 articles were screened from which 132 full text articles were analyzed and 37 finally included in the systematic review. Most of the studies evaluated the color matching abilities of dental students in vitro with shade tabs or extracted teeth. Out of the 37 articles included, 25 reported no significant difference in shade matching abilities between the sexes. Of the 12 studies that found a significant difference, 11 reported that females had better scores in shade matching exercises. For all studies a low risk of bias was revealed for most of the domains.Conclusions: While the non-homogeneity of the settings and methods in the included studies make it impossible to construct aggregate statistic, this systematic review suggests that the sex is unlikely to be a critical factor influencing color matching abilities.Clinical significance: This study suggest that sex of dental professionals does not play a critical factor in matching satisfactory color of future dental restoration with surrounding teeth.

“…An improvement in the cognitive abilities and visual color differentiation skills of the dentist or user is possible with appropriate training sequences [23,31,[43][44][45]. The authors used templates that were matched in training with the appropriate reference scale [22,23,26,[45][46][47][48][49][50]. McMaugh examined the differentiation ability of different cohorts: undergraduates (first and fourth clinical years), dentists and esthetic dentistry specialists, and dental technicians [22].…”

Visual color determination (VCD) requires color competence and individual training. The aim of this study was to evaluate the deviations in students’ VCD with two different reference scales. The research hypothesis was that none of the color references would provide a better result. Participants evaluated nine templates randomly using two reference scales (VITA-classical (VC) and 3D-Master-Toothguide (3DM_TG)). The color distance to the chosen color (ΔEab) was calculated in the CIELAB 2000. The sum’s changes in the parameters (LCh°) represented the target variable. Results were evaluated with non-parametric, rank-scaled methods, utilizing the median with a 25%-75% quartile. The significance level (α = 0.05) is determined using the Student’s t-test. The mean ± 95%CI (SD) was −1.27 ± −1.09 (3.18); the median ΔE00 was −1.49 (−1.97; 0.96) for dC3DM_TG. The determination with VC showed noticeable differences (dCVC), with a mean ΔE00 of 0.00 ± 0.00 (2.20) and a median ΔE00 of 0.00 (1.17; 1.71). The standard error was 0.19 for the dCVC and 0.27 for the dC3DM_TG. dC3DM_TG vs. dCVC showed significant differences at p < 0.001. The dental student’s VCD resulted in color deviations, regardless of the reference template used. The color deviations in hue and chroma were comparable, regardless of the reference scale. VCD’s early implementation in dental education is useful to avoid shade misjudgments and potentially expensive remakes of dentures.

“…No se encuentra el origen de la referencia.. Del análisis realizado se pudo observar que la mayoría de trabajos tiene un enfoque académico [16]- [17]; así mismo, muy pocos tienen en cuenta los escenarios reales [16] [18] [19] [20] [21], que se podrían trabajar para así disminuir la brecha que existe entre la teoría y la práctica. Por otra parte, se observó que sólo dos trabajos tienen en cuenta aspectos del estudiante [22] [17], siendo este aspecto el apoyo a las habilidades visuales que este tiene.…”

Hoy en día, las personas interactúan con las nuevas tecnologías porque con ellas pueden hacer cosas que nunca pudieron hacer hace quince o veinte años. Una de esas cosas es estudiar usando Internet o libros electrónicos, pero incluso con este progreso tenemos una falta de información. ¿Por qué? Porque pocas tecnologías tienen en cuenta los diferentes aspectos del usuario. Como ejemplo, Endodontics tiene una gran variedad de objetos de aprendizaje que los estudiantes pueden utilizar para apoyar su proceso de aprendizaje, pero esas tecnologías no tienen en cuenta los estilos de aprendizaje, el conocimiento o el rendimiento del alumno que está teniendo en su proceso. Por esa razón, decidimos crear un objeto de aprendizaje virtual con respecto a los estilos de aprendizaje, el proceso de aprendizaje y el rendimiento del alumno en Endodoncia.
