Diagnodent aids in the detection of caries on the occlusal surface (biting surface) of a tooth. Diagnodent uses laser technology to detect and quantify hidden or sub-surface caries by measuring laser fluorescence within the tooth structure. Even very small lesions are detected at the earliest stage, enabling Dr. Kopper to protect and preserve the tooth substance. The diagnodent laser caries detection aid removes the doubt from treatment decisions regarding hidden caries or questionable stained grooves. The device’s ability to see into occlusal pits and fissures enables Dr. Kopper to treat and or monitor sub-surface caries lesions with confidence.
