RESUMO
OBJECTIVE: Color Adjustment Potential evaluates the color blending of dental Composite Resins. While Color Adjustment Potential is simple, its clinical relevance is unclear. This research aims to understand it better and to create an index for Composite Resins with meaningful clinical interpretation. MATERIALS AND METHODS: Single and double shade composite disks of various diameters and opacities were created to test the indices. Color measurements used a dental colorimeter, avoiding subjective assessments. Color Adjustment Potential analysis of each material revealed insights, leading to the creation of a new Color Blending Threshold, providing a clinically relevant numerical value for Composite Resins. RESULTS: Color Adjustment Potential's numerical significance was clarified and introduced a new index for clinical applications. Color adaptation of each test shade to all Vita shades was also calculated, useful for single-shade restorations in open and closed cavity types. CONCLUSIONS: The proposed Color Blending Threshold defines the open/closed cavity dimension that can be adequately restored with a single shade of resin composite. CLINICAL SIGNIFICANCE: Understanding how dental materials adapt to surrounding tooth colors enhances esthetic restorations, simplifies shade matching, and optimizes resin composite production. The proposed Color Blending Threshold is a parameter that directly relates to the clinical significance of a material's true color blending ability. It defines the cavity dimension that can be adequately restored with a single shade of resin composite while ensuring that the resulting color difference falls below a predetermined threshold, meeting the clinical requirements for an esthetic restoration.

The biggest challenge while restoring anterior teeth is shade matching. Hue, chroma, value, opacity, translucency, intensity and anatomy must be seen to be reproduced. To see we need light, knowing that there is a strong relation between the nature of light and the components of natural teeth. This article enlightens the way to do the shade matching and the stratification of anterior teeth by choosing the relevant materials to mimic the nature. The physical properties of natural and polarized light will be studied to understand their correlation with dental materials and natural teeth to use them in the best combination.

Restoring an anterior tooth has always been a challenge, regarding the shade matching, the choice of colors, opacities, translucencies of our composites and the final anatomical outcome. This article proposes a new method for color matching and a clinical stratification using a simple and reproducible procedure for anterior restorations. The physical and optical characteristics of enamel and dentine will be studied and applied to our dental materials that we are using to restore anterior teeth.

While restoring an anterior tooth, shade matching is one of the crucial points that we can face to have an esthetic final outcome. After studying the physical and optical characteristics of enamel and dentine in the first part of this article, the second part will propose a new method for color matching and a clinical stratification using a simple and reproducible procedure for anterior restorations with only one dentine and one enamel shade.
