Abstract
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.
