| Outline of Final Research Achievements |
We aimed to assess the efficacy of a proton pump inhibitor (PPI) on sleep bruxism (SB) and to examine the symptoms and condition of upper gastrointestinal (GI) tract in SB patients. Twelve SB patients underwent an assessment of GI symptoms and endoscopy. At baseline, the mean frequencies of EMG bursts and RMMA episodes were 65.4 and 7.0 times/h, respectively, and at least one grinding noise was confirmed in all participants. The mean FSSG score was 8.4, and 41.7% of patients were diagnosed with GERD. Reflux esophagitis was confirmed in 6 patients. Polysomnography were performed on days 4 and 5 of administration of the PPI (rabeprazole) or placebo. PPI administration yielded a significant reduction in the frequency of EMG bursts, RMMA episodes, and grinding noise. No significant differences were observed regarding the swallowing events and sleep variables. The results of this trial highlight the potential application of pharmacological GERD treatment for SB patients.
