BACKGROUND
The effect of awake and sleep bruxism on periodontal disease has not been evaluated separately to date. Furthermore, there are few studies that have focused on awake bruxism with light force.
OBJECTIVE
The study aimed to investigate the frequency of sleep and awake bruxism in patients with periodontal disease.
METHODS
The subjects were 57 patients with periodontal disease who visited the Department of Periodontics of the Dental Hospital affiliated with Tokyo Medical and Dental University. Subjects were asked to fill out a questionnaire consisting of three items on bruxism (sleep and awake bruxism), and the maximum community periodontal index was investigated.
RESULTS
The proportions of individuals with high sleep bruxism-related signs and high awake bruxism-related signs were 6.0% and 44.0%, respectively. No significant difference was found in the comparison of maximum community periodontal index proportions between individuals with high sleep bruxism-related signs and high awake bruxism-related signs.
CONCLUSION
The results of this survey of patients with periodontal disease showed that the proportion of subjects with high awake bruxism-related signs subjects was higher than those of the subjects with high sleep bruxism-related signs. Sleep bruxism has attracted attention as a factor influencing periodontal disease, and our data suggest that patients with periodontal disease demonstrate more bruxism while being awake than during sleep.
背景
迄今为止，尚未分别评估清醒时磨牙症和睡眠时磨牙症对牙周疾病的影响。此外，很少有研究关注轻度力量的清醒时磨牙症。
目的
本研究旨在调查牙周疾病患者睡眠时磨牙症和清醒时磨牙症的发生频率。
方法
研究对象为57名前往东京医科齿科大学附属牙科医院牙周科就诊的牙周疾病患者。研究对象需填写一份包含三项关于磨牙症（睡眠时磨牙症和清醒时磨牙症）内容的问卷，并调查社区牙周指数最大值。
结果
睡眠时磨牙症相关体征较高者和清醒时磨牙症相关体征较高者的比例分别为6.0%和44.0%。睡眠时磨牙症相关体征较高者与清醒时磨牙症相关体征较高者在社区牙周指数最大值比例比较中未发现显著差异。
结论
本次对牙周疾病患者的调查结果显示，清醒时磨牙症相关体征较高的受试者比例高于睡眠时磨牙症相关体征较高的受试者。睡眠时磨牙症作为影响牙周疾病的一个因素已受到关注，我们的数据表明，牙周疾病患者清醒时的磨牙症比睡眠时更多。
