Awake and Sleep Bruxism Among Israeli Adolescents
Conclusions: Among adolescents, sleep and awake bruxism are associated with emotional aspects as well as with facial pain symptoms and/or masticatory system disturbances. Awareness is recommended to decrease potential risks to teeth, dental restorations, and the masticatory system.
Introduction
Definition of bruxism has been under debate for some time. In 2013 (1), an international group of bruxism experts issued a consensus proposal based on the concept that bruxism is “a repetitive jaw activity” which can occur during sleep (sleep bruxism- SB) or during wakefulness (awake bruxism–AB). In 2018, it was argued that AB is a masticatory-muscle activity which occurs during wakefulness and is characterized by repetitive or sustained tooth contact and /or by bracing or thrusting of the mandible (2). Such behavior does not necessarily include other behaviors that people engage during the day, such as lip biting, pen biting etc. Those are rather referred to as oral habits.
