Device Story

Caries Detector is a dental dye-based diagnostic agent used to identify areas of tooth decay. The device is applied topically to the tooth surface by a dental professional; the dye stains carious dentin, allowing the clinician to visually distinguish decayed tissue from healthy dentin. It functions similarly to plaque disclosing agents; it does not involve electrical current, optical instrumentation, or chemical reactions. The output is a visual stain that assists the clinician in identifying the extent of caries during restorative procedures, facilitating targeted removal of decayed tissue and preservation of healthy tooth structure.
