Bruxism and Stress: Ultrasonographic Masseter Muscle Assessment and Salivary Melatonin‐Cortisol Dynamics

open access: yesJournal of Oral Rehabilitation, EarlyView.
ABSTRACT Background Bruxism is a parafunctional activity characterised by teeth grinding or clenching, often associated with stress and neurophysiological factors. Its aetiology is multifactorial, with recent studies emphasising neurotransmitters and hormonal imbalances, particularly melatonin and cortisol. This study assesses masseter muscle thickness
