Abstract
A method for localizing gingival inflammation using an oral care device, comprising: emitting (520) light by one or more light emitters (42) of the oral care device; obtaining (530), at a first rate by one or more light detectors (40), reflectance measurements for a plurality of locations to generate first reflectance data; determining (540), by a controller (30) of the oral care device using the first reflectance data, whether the location comprises gingiva; obtaining (550), at a second rate by the one or more light detectors, reflectance measurements for each location determined to comprise gingiva to generate gingiva reflectance data, wherein the second rate is faster than the first rate; and determining (560), by the controller using the gingiva reflectance data, whether gingiva at that location is inflamed.
