Detecting the invisible If you cannot detect the disease, how can you treat it? Dentists often experience anxiety when attempting to diagnose the phenomenon known as hidden caries. A suspicious-looking tooth presents a treatment dilemma for dentists. Should the tooth be opened up? What if no caries is found? Should the tooth just be watched, or does that give caries more time to destroy the tooth's surface? A changing caries model: due to floridation, caries has gone "underground". While helping to improve the oral health of many people, fluoridation has resulted in harder tooth enamel. Incipient caries lesions that once began on the tooth's surface have no migrated below the surface. Proven clinical results: Treatment decisions require a higher degree of certainty. The DIAGNOdent laser caries detection aid removes the doubt from treatment decisions regarding hidden caries ore questionable stained grooves. The device's ability to see into occlusal pits and fissures enables dentists to treat sub-surface caries lesions with confidence.
