What is the definition of translucency?
What is the definition of translucency?
- A property of substances that permits the passage of light but disperses the light, so objects cannot be seen through the material (correct)
- A property of substances that allow the passage of light and objects may be clearly seen through them

Study Notes
Color Perception
- The perception of color is a physiological response to a physical stimulus.
- There are only three primary colors: red, green, and blue (or violet).
- Any other color can be produced by combining these primary colors.
- Yellow light, for example, is a mixture of green and red lights.
Munsell System
- The Munsell System is a method used to define and measure color.
- The system has three dimensions of color: hue, chroma, and value.
Dimensions of Color
- Hue: the basic color of an object (red, green, or blue), determined by the wavelength of light.
- Chroma: the intensity or strength of hue, with higher chroma indicating a more intense color.
- Value: the amount of lightness or darkness in the color.
Opacity, Translucency, and Transparency
- Opacity: a property of materials that prevents the passage of light.
- Translucency: a property of substances that permits the passage of light but disperses it, making objects unclear.
- Transparency: a property of substances that allows the passage of light, making objects clearly visible.
Perception of Color
- Shade selection is subjective and dependent on the observer, object, and light source.
- There are three common light sources in a dental office: natural, incandescent, and fluorescent.
Surface Finish and Thickness
- A rough surface appears lighter than a smooth surface of the same material due to the reflection of white light.
- The thickness of a restoration affects its appearance, with opacity increasing as thickness increases.
