What is the primary light manifestation used in the diagnosis of dental caries?

The primary light manifestation used in the diagnosis of dental caries is fluorescence. In dentistry, specifically during the detection of carious lesions, laser-induced fluorescence techniques are often utilized. When exposed to specific wavelengths of light, healthy tooth enamel and carious tissue exhibit different fluorescence patterns. This variation allows dental professionals to identify caries that may not be visible through traditional examination methods, providing a more accurate diagnosis and enabling early intervention.

Fluorescence is advantageous because it can reveal subsurface lesions, making it a valuable tool in preventive dentistry. The fluorescence from decayed tissue typically differs in intensity compared to healthy enamel, enhancing the ability to detect caries in their early stages. This technology is instrumental in improving patient outcomes by allowing for timely treatment, potentially saving tooth structure and enhancing overall oral health.
