“…However, these data were based on an individual's own awareness, and it is unclear whether they were actually biting down during each situation. A mouthpiece type device that detects biting and clenching in real time has been developed [14]. We believe that it is necessary to use this device to determine the actual status of biting and clenching one's jaws during Kendo practice.…”

This study evaluated the risk of oral injury in Kendo. We hypothesized that Kendo players in Japan may experience oral injury due to the use of face protector for kendo (men) with inaccurate measurements or wearing it incorrectly. The survey included 400 kendo players (male, 276; female, 174) and covered four areas: the relationship between the characteristics, percentage of oral injury, temporomandibular disorder (TMD), and use of men. Based on the who experience of oral injury, participants were classified into ‘trauma’ and ‘non-trauma’ groups. Those who suffered oral injury were 179 (44.8 %; males, n=118; females, n=61). In the past month, 32 (8.2%) Kendo players reported that their matches/training were affected by dental/oral problems. For TMD, 50 participants had a total score >8.5 from four screening questions. For 289 (72.3%) participants, the men they are currently wearing fit well. Of those that reported that their men do not fit properly, 48 (12.0%) felt that their men were too large, and 14 (3.5%) felt that their men were too small. Years of experience and clenching of one’s jaws during an offensive Kendo movement significantly contributed to oral injury. Clenching one’s jaws during a defensive Kendo move, current men fit, sleep bruxism, and morning symptoms from sleep bruxism significantly contributed to TMD. Men with an accurate sizing allows proper field of vision, eliminating head shifting inside men during strikes and movements. This suggests that vision can be secured by adjusting the ties on men, chin movement, and the way one looks through the men. Since Kendo equipment is originally a Japanese craft, it has high artistry. Thus, properly worn Kendo equipment brings higher functionality and esthetic appeal.

“…[13] introduced comfortable around the ear sensors (cEEGrids) for detecting awake bruxism, analysing bruxism-related events in contrast to the other facial activity events, such as chewing and speaking. [12] developed a wearable mouthguard with a force sensor to analyse teeth clenching during exercise. [6] proposed to detect sleep bruxism by using electromyography (EMG) and electrocardiogram (ECG) signals in combination, which produced substantially better results than using only EMG.…”

Bruxism is a disorder characterised by teeth grinding and clenching, and many bruxism sufferers are not aware of this disorder until their dental health professional notices permanent teeth wear. Stress and anxiety are often listed among contributing factors impacting bruxism exacerbation, which may explain why the COVID-19 pandemic gave rise to a bruxism epidemic. It is essential to develop tools allowing for the early diagnosis of bruxism in an unobtrusive manner. This work explores the feasibility of detecting bruxismrelated events using earables in a mimicked in-the-wild setting. Using inertial measurement unit for data collection, we utilise traditional machine learning for teeth grinding and clenching detection. We observe superior performance of models based on gyroscope data, achieving an 88% and 66% accuracy on grinding and clenching activities, respectively, in a controlled environment, and 76% and 73% on grinding and clenching, respectively, in an in-the-wild environment.

“…The mouthguard wearable platform was utilized not only for salivary biosensors, but also for physical sensors, which is capable of monitoring physical teeth clenching. 27 From the 2010s to recent years, wearable devices have been significantly developed to monitor healthcare-related various parameters in the oral cavity.…”

Review—Lab-in-a-Mouth and Advanced Point-of-Care Sensing Systems: Detecting Bioinformation from the Oral Cavity and Saliva

Cavitas sensors and point-of-need sensors capable of providing physical and biochemical information from the oral cavity and saliva have attracted great attention because they offer remarkable advantages for noninvasive sensing systems. Herein, we introduce the basic anatomy and physiology of important body cavities to understand their characteristics as it is a pivotal foundation for the successful development of in-mouth devices. Next, the advanced development in lab-in-a-mouth sensors and point-of-need sensors for analyzing saliva are explained. In addition, we discuss the integrations of artificial intelligence and electronic technologies in smart sensing networks for healthcare systems. This review ends with a discussion of the challenges, future research trends, and opportunities in relevant disciplines. Mouthguard-based sensors and conventional salivary sensing devices will continue to be significant for the progress in the next-generation sensing technologies and smart healthcare systems.
