What does 'chroma' refer to in dental color terminology?

The brightness of a color
The amount of saturation of a hue
The lightness or darkness of a color
The temperature of a color

The correct answer is: The amount of saturation of a hue

Chroma in dental color terminology specifically refers to the amount of saturation of a hue. Saturation indicates the intensity or purity of the color; a high chroma means a more intense, vivid hue, while a low chroma implies a more muted or grayish color. This concept is crucial in dentistry when selecting the shade of dental materials, as it assists in achieving a natural and aesthetically pleasing appearance that closely matches the patient's existing teeth. Understanding chroma allows dental professionals to differentiate between shades effectively and ensure optimal color matching for restorations and prosthetics.
