This controlled pre-post study evaluates the effect of non-surgical periodontal therapy on awake and sleep bruxism in patients with Stage III and IV periodontitis. Bruxism activity and periodontal status will be assessed at baseline and three months after treatment.
This is a non-randomized controlled pre-post clinical study designed to investigate the impact of periodontal treatment on awake and sleep bruxism in individuals with advanced periodontitis. Two groups will be included: a periodontitis group undergoing full non-surgical periodontal therapy (step 1 and 2), and a healthy control group receiving supragingival plaque removal and polishing. All participants will receive standardized oral hygiene instructions and motivation. Bruxism activity will be recorded using portable electromyography (EMG) devices at baseline and after three months, evaluating both sleep and awake bruxism through Bruxism Work Index (BWI) and Bruxism Time Index (BTI). Clinical periodontal parameters will also be collected at both time points to assess potential correlations with bruxism variation.
