Problems solved by technology

However, existing methods and devices do not adequately identify or quantify tissue inflammation, especially localized inflammation
For example, the detection of gingival inflammation is poorly achieved with handheld devices because these devices either analyze a large area of ​​the mouth, resulting in a large signal-to-noise ratio that interferes with detection, or require a large number of measurements that are not user-friendly
Additionally, the movement of the user's hand can cause artifacts and poor readings on handheld devices
Periodontal disease often goes undetected as a result

Embodiment Construction

[0032] 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 sensor arrays having one or more light emitters and at least one light detector to obtain information about gum tissue at one or more sampled locations. The light sources of the one or more light emitters are configured to emit light such that a plurality of different wavelengths are emitted sequentially in a first sequential pattern and subsequently sequentially emitted in a second sequential pattern opposite the first sequential pattern. The one or more light detectors are c...

Abstract

For localizing the gingival inflammation within a user's mouth, the following steps are carried out by using an oral care device (10) of (i) sequentially emitting (520) light by a plurality of light sources (48) 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 (530) light in a second sequential pattern which is the reverse of the first sequential pattern; (iii) obtaining (540), by a light detector (40), 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 (550), by a controller (30), first reflectance data and second reflectance data for each wavelength to generate averaged reflectance data; and (v) determining (570), by using the averaged reflectance data, whether gingiva at the location is inflamed.

Description

technical field [0001] The present disclosure is generally directed to methods and systems for improved detection of localized gingival inflammation using oral care devices. Background technique [0002] Proper brushing, including when and how often you brush, can help promote long-term dental health. People who don't brush their teeth regularly or don't brush enough can experience many dental problems, especially in specific areas or parts of the mouth. Among people who regularly brush their teeth, even when following standard brushing routines (such as brushing for two minutes twice a day), incorrect brushing habits can lead to poor brushing coverage and, consequently, to failure in the cleaning process. Surfaces that have been adequately cleaned. [0003] In fact, an estimated 50 percent of adults in the United States suffer from periodontal disease, which can range in severity from gingivitis to periodontitis. However, consumers often fail to detect the early signs of...
