A research group from Okayama University and Notre Dame Seishin Women's University has discovered for the first time in the world that university students who grind their teeth while sleeping tend to consume less dietary fiber.
According to Okayama University, the research group investigated the presence or absence of bruxism during sleep using an electromyograph, in addition to an intraoral examination and a questionnaire survey, targeting students at Okayama University and Notre Dame Seishin Women's University.In addition, they estimated the intake of 1 different nutrients over the past month, comparing students who grind their teeth with those who do not.
As a result, it became clear that students who consumed less dietary fiber were more likely to grind their teeth during sleep.A comparison of the top 25% and the bottom 25% of dietary fiber intake confirmed that students who grind their teeth during sleep consume significantly less food than those who do not.
Bruxism during sleep can lead to symptoms such as tooth loss, progression of periodontal disease, and jaw pain, and can have a significant negative impact on the mouth.A common remedy is symptomatic treatment of protecting the teeth by wearing a mouthpiece, and no method has been found to reduce bruxism itself.The research group believes that the results of the study will serve as an opportunity to establish a new method to combat bruxism.
