This study aims to investigate the association between periodontitis Stage III and IV and the intensity and duration of sleep bruxism episodes. Surface electromyography (EMG) of the masseter muscle will be used to instrumentally assess sleep bruxism in patients with and without periodontal disease
The purpose of this cross-sectional study is to evaluate whether patients with Stage III and IV periodontitis exhibit differences in sleep bruxism activity compared to individuals without periodontal disease. Participants will undergo comprehensive periodontal assessment and 24-hour EMG recording of the masseter muscle using a portable device. Bruxism activity will be quantified using the Bruxism Work Index (BWI) and Bruxism Time Index (BTI). The study aims to clarify the potential relationship between periodontal inflammation and masticatory muscle activity during sleep, following standardized diagnostic and recording protocols

Participants will undergo 24-hour surface electromyographic recording of the left masseter muscle using the dia-BRUXO portable device to quantify sleep bruxism activity through Bruxism Work Index (BWI) and Bruxism Time Index (BTI).

Sleep Bruxism Work Index (BWI)
BWI is calculated as the percentage of muscle work exerted during bruxism-related masticatory activity relative to the theoretical maximum work. It will be used to assess the intensity of sleep bruxism based on EMG recordings of the masseter muscle
Time frame: Within 24 hours after EMG device application
