Abstract
For localizing gingival inflammation within a user's mouth the following steps are carried out using an oral care device (): (i) sequentially emitting () light by a plurality of light sources () in a first sequential pattern, wherein at least some of the plurality of light sources are configured to emit light of different wavelengths; (ii) sequentially emitting () light in a second sequential pattern which is the reverse of the first sequential pattern; (iii) obtaining (), by a light detector (), reflectance measurements to generate first reflectance data from light emitted in the first sequential pattern, and to generate second reflectance data from light emitted in the second sequential pattern; (iv) averaging (), by a controller (), first reflectance data and second reflectance data for each wavelength to generate averaged reflectance data; and (v) determining (), using the averaged reflectance data, whether gingiva at the location is inflamed.
