摘要： A gum diagnosis assisting apparatus includes a sectional data extractor configured to extract sectional data in a depth direction of a gum marginal portion from three-dimensional point group data of a frontal view of an oral cavity, and a gum diagnosis data generator configured to process the sectional data into a format suitable to a gum diagnosis to generate gum diagnosis data. The gum diagnosis data generator is configured to generate, for example, a two-dimensional graph as the gum diagnosis data with a right-left direction or the up-down direction of the frontal view of the oral cavity as a first axis and the depth direction of the frontal view of the oral cavity as a second axis.

摘要： The dental health assessment assisting apparatus includes a gray scale converter configured to convert a fluorescence image obtained by imaging fluorescence of a tooth irradiated with excitation light into a gray scale image, a gray scale value acquiring unit configured to acquire gray scale values of a reference point and a plurality of evaluation points in an image of the tooth in the gray scale image, a normalization unit configured to normalize the gray scale values of the plurality of evaluation points by the gray scale value of the reference point, and a dental health assessment data generator configured to generate dental health assessment data visually representing the gray scale value of the reference point and the gray scale values of the plurality of evaluation points which have been normalized.
