Embodiment Construction

[0029]The present disclosure describes various embodiments of methods and devices for detecting gingival inflammation using oral care devices. More generally, applicants have recognized and appreciated that it would be beneficial to provide a system for detecting localized tissue inflammation. Accordingly, methods described or otherwise contemplated herein provide a device, such as an oral care device, configured to obtain measurements of gum tissue. The oral care device includes one or more of various sensors having one or more light emitters and light detectors to obtain information about gum tissue at multiple sampling locations. The one or more light emitters are configured to emit light at a first intensity, and the photodetector is configured to obtain a reflectance measurement from a location within the user's mouth. The device determines which locations include gums, and the device then automatically adjusts the intensity of one or more light emitters illuminating the...

Abstract

A method (500) for localizing gingival inflammation using an oral care device (10), the method comprising: (i) emitting (520) light at a first intensity by a light emitter (42); (ii) obtaining (530) first reflectance measurements by a light detector (40) from locations within the user's mouth to generate first reflectance data; (iii) determining (540), by a controller (30) from the first reflectance data, whether the location comprises gingiva; (iv) automatically adjusting (550), based at least in part on the first reflectance data, the intensity of a light emitter to a second intensity different from the first intensity, and / or automatically adjusting (550) a gain of a light detector; (v) obtaining (560) a second plurality of reflectance measurements by the light detector of the oral caredevice for at least some of the locations; and (vi) determining (570), using the second plurality of reflectance measurements, whether gingiva at the location is inflamed.

Description

technical field [0001] The present disclosure is generally directed to methods and systems for improving detection of localized gum inflammation via automatic brightness and / or gain control using oral care devices. Background technique [0002] Proper brushing (including brushing length and coverage) helps promote long-term dental health. Individuals who do not brush their teeth regularly or adequately can experience many dental problems, especially in specific areas or zones of the oral cavity. In individuals who brush their teeth on a regular basis, incorrect brushing habits can result in poor brushing coverage and thus with insufficiently cleaned surfaces even during the cleaning phase of a standard brushing regimen such as brushing for two minutes twice a day. [0003] In fact, it is estimated that 50% of the adult population in the United States is affected by periodontal disease, where the severity of the disease ranges from gingivitis to periodontitis. However, cons...
