Sub-surface caries lesions can be difficult to detect using traditional tools. In nearly 80% of cases, fissure caries have been detected in children and adolescents. The DIAGNOdent laser is a relatively new technology that allows us to properly identify and treat lesions and decay on the tooth in a non-invasive manner. It is especially useful for pit and fissure areas. Studies have shown that when solely using conventional procedures and instruments, tooth decay lesions often go unnoticed. With the help of the DIAGNOdent laser, Doctor Florio and Doctor Kohner will be able to eradicate or prevent any sub-surface caries lesions.
