About

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

Full description

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

Trial design

40 participants in 2 patient groups

Periodontitis Group

Description:

Patients diagnosed with Stage III or IV periodontitis according to the 2017 World Workshop classification. Participants will undergo full-mouth periodontal examination and 24-hour surface EMG recording of the masseter muscle to assess sleep bruxism activity.

Treatment:

Device: Surface Electromyography (dia-BRUXO)

Healthy Control Group

Description:

Participants without clinical signs of periodontal disease, matched by age and sex to the periodontitis group. They will also receive a full-mouth periodontal screening and 24-hour surface EMG recording of the masseter muscle for sleep bruxism assessment.

Treatment:

Device: Surface Electromyography (dia-BRUXO)
