Abstract

See full text

A method and an apparatus for measuring and displaying dental plaque are provided, and the method includes the steps of dividing near infrared light output from a light source into measurement light and reference light, applying the measurement light toward a tooth in an oral cavity and scanning the tooth with the measurement light, producing interference light from reflected light and back-scattered light from the tooth and the reference light, generating an optical coherence tomographic image based on a scattering intensity value of the interference light, extracting a dental plaque region having a specific scattering intensity value from the optical coherence tomographic image, and quantifying the dental plaque. A method and an apparatus for measuring and displaying gingiva and/or alveolar bone are further provided. A method and an apparatus for quantifying dental plaque, digitizing the dental plaque, and generating an image of the dental plaque are further provided.
