The effect of gender and clinical experience on shade perception

Abstract

Objective Shade matching is a critical procedure in prosthetic dentistry. The correct identification of the shade by the doctor as well as the perception of the shade by the dental technician becomes critical due to the high patient expectations. The current study aims to evaluate the effect of gender and clinical experience on shade perception by dental professionals. Materials and Methods A total of 100 dental professionals with normal color vision who were categorized as dental students, dental doctors, and dental specialists were included in the study. Masked A2 and B2 shades tabs were made to match with a complete set of shade guide. The obtained data were entered, coded, and analyzed using SPSS version 17 for Windows. Results Total number of participants who identified both shade tabs correctly was 44%. There were no statistically significant differences among the gender or the clinical experience with regard to correct identification of shade tabs. Conclusion Within its limitations of fewer number (two) of shade tabs for comparison, the study concludes that multiple opinions may be taken clinically irrespective of the gender or clinical experience as gender and experience do not have a significant role to play for shade matching in prosthetic and restorative dentistry.

Shade Matching in Fixed Partial Denture Patients

“…The frequencies calculated are tabulated and depicted in (Table 1 and Table 2) .Chi square test was done between age group and colour match. Results showed statistically significant differences in shade matching among the groups,(P<.0.001).with very good and good shade matching being the most predominant ones (Figure 1 ).The results obtained states that the shade match is highly achieved and it consensus with the study by 16,26,7 which states that the shade match in the age group has high satisfactory population with very low crevice in shade match of the fixed partial dentures.…”

“…1,2 .The aesthetic success is dependent upon the close shade matching between the dental restoration and the adjacent teeth 3,4 .The shade matching is done to adapt restoration with the surrounding tissues 5,6,7,8 . The demanding aspect within the aesthetic dentistry is regarding the duplication and characterisation of colour 5,9,10 .The shade perception is psychophysiological response it is regulated by the human eyes and sensory structures of brain towards the reflection of light spectrum from any object 2,11,12 .Some elements give direct demand and impact on the colour of a restoration 13,14 .The common elements that gives impact includes lightning conditions, thickness of porcelain, soft tissue colour, core material, soft tissue shade selection system, firing process and fabrication 15,16,17 . The judgement made on shade selection has some factors that include ambient light, surrounding colour, clothes, makeup of the patient and chromatic perception of the dentist 18,19,20 .These factors results in frequent errors while performing shade selection 21,22 There are various approaches in shade selection method which is used for aesthetic success in shade match 23,24 .The study was to determine shade matching in fixed partial denture patients 25,26…”

Comparing the effectiveness of shade measurement by intraoral scanner, digital spectrophotometer, and visual shade assessment

“…39 However, several studies found no significant differences in the shade matching results between men and women. 11,40 Therefore, five men and four women (aged 20-25 years) participated in our study as examiners, and we did not find any differences in shade matching reliability between genders. Age may also influence tooth shade determination ability.…”

Effect of assessor's sex on visual color matching in dentistry: A systematic review of the literature

“…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). There were 4 studies that used daylight as the single source of light, of which 1 reported significantly better female performance, 54 while 1 found no significant difference 1,32,33 . Artificial light was the main light source in 23 studies.…”

“…3,4 Improper shade selection is a frequent reason for refabrication of dental restorations. 1,5 Proper color matching based on the surrounding teeth is thus a critical, yet highly challenging, task for the dentist or dental technician. The commonly used international standards for color research in dentistry are defined by the International Organization for Standardization and Commission Internationale de l'Eclairage.…”
