Effect of yellow anodization of titanium on the shade of lithium disilicate ceramic with different thicknesses
The color of the titanium abutment can affect the shade of the definitive restoration. Methods such as anodic oxidation, which changes the gray color of implant abutment to yellow, have been advocated to mask the unesthetic gray color of the abutment. However, whether a yellow anodized titanium abutment can prevent discoloration of translucent ceramic restorations is uncertain.Masking ability of implant abutment substrates by using different ceramic restorative systems
Information regarding the masking ability of ceramic crowns over different implant abutment materials is scarce.Effects of background color and thickness on the optical properties of CAD-CAM resin-matrix ceramics
Information regarding the masking ability of computer-aided design and computer-aided manufacture (CAD-CAM) resin-matrix ceramic materials with different compositions is scarce.Comparison of translucency and opalescence among different dental monolithic ceramics
Monolithic ceramic restorations designed by computer-aided design and computer-aided manufacturing are increasingly being used by clinicians. With the introduction of new materials, their optical characteristics also need to be investigated.Effect of variations in facial flow curves on the perceptions of smile esthetics by laypeople
Information about the effect of the facial flow concept on the smile esthetic perception of laypeople is lacking.Effect of CAD-CAM ceramic materials on the color match of veneer restorations
With the different translucency levels and types of computer-aided design and computer-aided manufacturing (CAD-CAM) ceramic materials, choosing the most appropriate CAD-CAM ceramic materials to better reproduce the color appearance of natural teeth can be challenging.Effects of shade and thickness on the translucency parameter of anatomic-contour zirconia, transmitted light intensity, and degree of conversion of the resin cement
Anatomic-contour zirconia prostheses are usually cemented with resin cement. However, information regarding the effects of the zirconia shade and thicknesses on the translucency of the prosthesis, the intensity of the transmitted light beneath the prosthesis, and the subsequent degree of conversion in the resin cement is sparse.Illuminant metameric effects on interbrand and intrabrand color differences of direct composite resins
Information on the illuminant metameric effects on the intrabrand and interbrand differences in color of direct composite resins is lacking.Comparative analysis of smile esthetics between top celebrity smile and a Southern European population
The analysis of different parameters involved in the esthetic perception of the smile is important for the correct planning of cosmetic dental treatments.A comparison of ceramic crown color difference between different shade selection methods: Visual, digital camera, and smartphone
The light source stability of digital cameras and smartphones is important in shade matching in restorative and prosthetic dentistry to communicate objectively with the dental laboratory. Techniques that standardize the light source of such devices are lacking, and this limitation can lead to color mismatches, difficulties in color communication, and treatment documentation.An analysis of an educational method to improve the shade-matching ability of dental students
The predoctoral dental curriculum includes didactic lectures, demonstrations, and training on shade-matching techniques and protocols. However, a significant percentage of esthetic failures are still observed clinically. An assessment is required to determine whether reevaluation and modification of this training protocol would help future dental practitioners better perceive and communicate the dental shade.An evaluation of factors affecting dental shade matching in first-year dental students
Shade selection has become more important and challenging as it becomes more emphasized in esthetic dentistry. It would be beneficial to screen dental students early in their predoctoral education for any deficiencies in color discrimination. Specific tests that reliably predict dental shade-matching ability have not been fully established.Effect of ambient lighting conditions on tooth color quantification in cross-polarized dental photography: A clinical study
Limited data are available in the dental literature regarding the effect of ambient lighting on the consistency of color quantification in cross-polarized photography.Self-perception and self-representation preference between 2-dimensional and 3-dimensional facial reconstructions among dentists, dental students, and laypersons
Computer-aided design (CAD) software can merge the intraoral digital scan with patient photographs or 3-dimensional (3D) facial reconstructions for treatment planning purposes. However, whether an individual perceives a 3D facial reconstruction as a better self-representation compared with a 2-dimensional (2D) photograph is unclear.Color perceptibility and validity of silicon carbide–based protective coatings for dental ceramics
A silicon carbide (SiC) protective coating has been developed for dental ceramics, but whether the coated ceramics can match the classical VITA shades is unclear.Optical effect of resin cement, abutment material, and ceramic thickness on the final shade of CAD-CAM ceramic restorations
High-translucency ceramics can be influenced by the underlying structure, altering the restoration shade. How this affects color matching is unclear.Dental student, dentist, dental assistant, and layperson perception of pink gingival porcelain color
How pink gingival porcelain color is perceived by participants classified according to profession and sex is unclear.Effect of color of the cement and the composite resin foundation on the resultant color of resin-matrix ceramics
An improper restoration color match to the adjacent natural teeth can jeopardize esthetic success. The type of resin-matrix ceramic (RMC), the shade of the underlying foundation, and the shade of cement may affect the optical behavior of RMC materials, but studies on this issue are lacking.Staining and aging-dependent changes in color of CAD-CAM materials
Consumption of some beverages and aging may affect the color of dental materials used in fixed prosthodontics, but their effect on recently introduced materials is not well known.Evaluation of the response of esthetic restorative materials to ultraviolet aging
The optical properties of esthetic computer-aided design and computer-aided manufacturing (CAD-CAM) materials can change depending on the clinical situation. Studies that compare esthetic CAD-CAM materials based on their optical properties are lacking.Analysis of color differences in stained contemporary esthetic dental materials
Although contemporary analytical methods are available for application to data which exhibit a lack of equality of variances or a lack of normality in the error distribution, little guidance is provided for selecting the methods of data handling and analysis which best fit color difference data for stained esthetic materials.What German dentists choose for their teeth: A Web-based survey of molar restorations and their longevity
Which restorative material is best suited for treating the posterior molar region is unclear. As dentists presumably choose the most appropriate restoration, German dentists were asked how their own molars were treated.Comparison of visual analog shade matching, a digital visual method with a cross-polarized light filter, and a spectrophotometer for dental color matching
During the selection of tooth color, subjective communication with the laboratory and an incorrect color registration technique can lead to a poor color match of a restoration to adjacent teeth and oral structures.Esthetic assessment of celebrity smiles
Guidelines for planning esthetic outcomes are sparse. The present study evaluated the most noticeable characteristics of the celebrities with the most esthetic smiles.Evaluation of YouTube videos about smile design using the DISCERN tool and Journal of the American Medical Association benchmarks
YouTube contains many videos on health-related topics. “Smile Design” is one that is frequently searched on YouTube. Whether YouTube can be considered useful for patients seeking information on smile design is unclear.
