ABSTRACT Background Bruxism is a parafunctional activity characterised by teeth grinding or clenching, often associated with stress and neurophysiological factors. Its aetiology multifactorial, recent studies emphasising neurotransmitters hormonal imbalances, particularly melatonin cortisol. This study assesses masseter muscle thickness using ultrasonography examines the relationship between salivary cortisol levels in bruxism.
