Ceramics Shade and translucency... Perception VS. Deception

Lecture Description: 

Color and translucency of a natural tooth is a spectacular phenomenon, and is different from one individual to another. Numerous ceramic systems have been recently introduced in efforts to restoring a tooth not only to its proper function, but also to its natural appearance. This presentation will focus on the inherent translucency of modern-day ceramics and compare them to those of enamel and dentin. Translucency perception is subjective and can vary from one person to another. Numerical enhancement in translucency values of certain ceramics may not be perceivable to the human eye. Furthermore, stains and glazes are added to these ceramics to mimic the natural appearance of the tooth structure. A focus on the durability and time-lasting evaluation of these stains and glazes will also be discussed.

Objective: 

• De ning translucency and its different measurement methods.
• Comparing translucency of enamel and dentin with ceramic systems according to existing translucency perception thresholds.
• Introducing translucency perception threshold according to translucency parameter values.
• An overview of durability and retention of ceramic stains and glazes.
