[Clinical application of carious dentin detectors].

Abstract

The authors present a quite unused technique that helps to simplify the cavity preparation in Operative Dentistry. As a sequence of his investigations that established a clear distinction between hardness and bacterial invasion of dentin, Fusayama searched for a simple clinical method that could avoid excessive removal of remineralizable dentin. The use of "Caries Detector" may provide in few minutes an immediate clinical distinction between "infected dentin" and "remineralizable dentin", by the direct application of a selective dye. The fundamental, mechanism of action, and the application technique of this product are described.
