Use of dyes in cariology.
The property of dyes to enhance contrast by their colour can be used in clinical dentistry and in investigations in vitro or in vivo. They have been used for indication of affected dental tissues, improvement of diagnostic methods, enhancement of patient awareness and information about specific processes. The development of particular dye systems, aimed at clinical application, is often laborious because of toxic effects, lack of specificity, irreversible staining or difficulties with removal of the dye. Clinically used dyes are often visually observed, which means a qualitative assessment of the staining, while quantification of the staining, if performed at all, is confined mostly to laboratory experiments. In this paper the application of dyes, arranged according to their specific purpose in cariology, is discussed, and a brief historical overview is given of the development of two particular dye applications for which commercial dye systems are now available. If certain requirements are met, dyes can be of great help in detection and quantification when used with several diagnostic methods.
