“…One of the most challenging branches of dentistry is aesthetic dentistry [ 4 ]. Color is one of the most important determinants of aesthetic dentistry, considering a variety of parameters such as the kind and intensity of the light source, the time of the day and year, the angle of incidence, and the patient's clothing, age, and gender [ 5 , 6 ]. The correct evaluation of tooth color is a critical stage in the proper planning and execution of dental procedures [ 7 ].…”

Background: When taking into account several factors, including the kind and intensity of the light source, the season, the angle of incidence, the patient's attire, age, gender, and the time of day and year, color is one of the most crucial variables of aesthetic dentistry. The most challenging part of prosthetic dentistry is choosing a replacement tooth's color so that it blends in with the surrounding teeth and covers gingival tissue. As a result of the fact that having an understanding of the concept of color is extremely important in order to achieve good aesthetics, and the distribution of color is highly important to achieve shade matching.Aim of the study: The goal of this study was to evaluate dental professionals' self-reported knowledge, attitudes, and practices regarding anterior tooth shade matching in Saudi Arabia.Methodology: This research study was conducted in Saudi Arabia from February to April 2022. Two hundred fifteen registered dental practitioners participated in the cross-sectional, closed-ended questionnaire-based survey. Dental health professionals working in dental colleges, dental clinics, or other dentally significant institutions like hospitals (both government and private) and their respective private practices in various capacities as professors, teachers, or post-graduate students answered the research questionnaire. Dentists who were not involved actively in shade selection or declined to participate in contact through the mail were excluded. Chi-square and Fisher's exact tests were used for the comparison of categorical data, and a p-value of 0.05 at 95% CI was statistically significant.Results: Among the questions that were asked, the majority of them said age, sex, gender play, and appointment timing, along with patient opinion play a very important role in shade selection. Moreover, among the patients, 34% noted the manual method of shade selection, and 45.6% of them chose a combination of manual and mechanical methods. When they were asked about the commonest reason they came across for doing a shade selection of anterior teeth, around 52.60% said aesthetics, while 20.90% said fracture of anterior teeth. While 19.1% of people used rubber dam isolation, 34.0% of them preferred the use of cotton rolls and absorbing points, and only 16.7% of them often used Teflon tape. The majority of them had difficulty with shade selection due to the light source, as viewing shades in poor quality light influences how color is perceived; thus, the quality of light is the most influential factor in shade-taking practices. Around 44.7% of them preferred to do shade selection under natural daylight.Conclusion: Based on the results obtained from the current study, the authors would like to conclude that more attention should be focused on improving the knowledge of color science and its application in aesthetic dentistry, as the color and appearance of teeth are complex phenomena with many factors. Hence, for a good aesthetic outcome to be achieved, the dentist should consider all possible entiti...

“…The use of a digital spectrophotometer (e.g., VITA Easyshade V; VITA Zahnfabrik H. Rauter, Bad Säckingen, Germany) or an intraoral scanning device (TRIOS 4; 3Shape A/S, Copenhagen, Denmark) would have been an alternative for objective shade determination (Preethi Suganya et al, 2020 ; Revilla‐León et al, 2021 ; Tabatabaian et al, 2021 ; Youssef, 2021 ). While these advanced shade selection methods unanimously are described as being more precise, the clinical relevance of such measurements has been questioned in a recent meta‐analysis as these may be too sensitive and differences recorded with such instruments may not be detectable by the unaided human eye (da Rosa et al, 2020 ).…”

“…Before the bleaching procedure, visual shade selection (Czigola et al, 2021 ) was done by an experienced clinician using the VITA classical A1–D4 shade guide (VITA Zahnfabrik H. Rauter, Bad Säckingen, Germany). Using a white backdrop, standardized photographs of the crowns were taken at a distance of 30 cm before and after bleaching with the previously selected shade depicted as reference (Klinke et al, 2021 ; Preethi Suganya et al, 2020 ). The digital camera (Nikon D90; Nikon Europe, Amsterdam, Netherlands) equipped with an objective lens (AF‐S VR Micro‐NIKKOR 105 mm; Nikon Europe) was set at 125/F40 and the flash (Speedlight SB‐29s; Nikon Europe) was set at M1/4.…”

Objectives: While various approaches are available for tooth whitening, the basic concept employs the use of peroxides in the form of gels, which are applied to tooth surfaces. Previous studies have shown that reactive oxygen species acting as potent disinfectants can be produced using boron-doped diamond (BDD) electrodes for the electrolysis of water. With these electrodes being applicable, for example, for endodontic treatment, it was the goal of this pilot study to use such electrodes for tooth whitening.Material and Methods: Two groups (n = 10) of intact clinical crowns were obtained by horizontally cutting off roots of extracted human teeth. The crowns were either bleached by applying a commercially available agent based on 40% hydrogen peroxide or were immersed in saline undergoing electrolysis with BDD electrodes.Whitening of specimens was judged on standardized photographs by examiners with three different levels of experience. Statistical analysis was based on Gwet's AC2 coefficient with quadratic weights, Shapiro-Wilk tests, and two-way analysis of variance of aligned rank transformed data (level of significance set at α = .05).Results: Levels of reliability ranging from fair to substantial were recorded for single persons while the level of reliability ranged between fair and moderate for groups of raters. The level of experience had no significant effect on the ratings (p = .2500).The bleaching method had a significant effect on ratings (p = .0005) with BDD electrodes showing less effect.Conclusions: Bleaching by applying BDD electrodes was possible, but was not as effective as the use of commercially available in-office whitening gel. A potential explanation may be seen in different concentrations of reactive oxygen species.

[ 20 21 ] SPs are traditional devices used in dentistry for measuring color in dentistry, whereas spectroradiometers are newly introduced instruments designed to create the most accurate and detailed color measurements.

Newer trends in shade matching have been driven by the market need for superior grade esthetic restorations. Modernized shade guides, obtainability of shade-taking devices, and research in the field of human color vision have ameliorated the capability of dentists to attain outstanding color-matched restorations. A detailed knowledge of natural teeth' appearance features is needed along with these new devices to increase shade-matching results.
