In the current media-driven era, the primary need has turned to aesthetically acceptable restorations which requires proper shade selection. Shade matching is one of the most challenging phases of restorative dentistry. The process of shade duplication has many attributes like environment, practitioner, lighting conditions and more that can lead to negative results. If proper protocol is not followed, a practitioner can make mistakes during the process. It is, hence, of utmost importance to have proper knowledge and understanding about the concepts behind shades and how to select them to achieve the most natural appearance of teeth. The current study focuses on understanding the concept of colour, its dimensions, factors that affect the tooth shade, optical properties of the teeth and by what methods can be used to measure teeth shade, and their recent advancements. This Study also focuses on the preferred clinical setting for the shade selection.
