Spectra_w_background_webSpectra looks like an intra oral video camera, but it doesn’t function like a video camera. Spectra helps the dentist identify tooth decay by revealing cariogenic bacteria based on the fluorescence principle. LED’s project high-energy blue-light with a wavelength of 405 nm onto the tooth surface. Light of this wavelength stimulates bacteria to fluoresce red, while healthy enamel fluoresces green.

With special imaging software the dentist views a live monitor image which highlights the carious lesions in different colors and defines the severity of each on a scale from 0 to 5. Based on this information the dentist can choose to observe or to restore. Images can be saved to the patient record for future reference.

The Spectra camera will also show bacterial plaque on the hard enamel surfaces. In this mode it acts as a high tech disclosing solution that doesn’t leave the patients looking like Count Dracula.
