Correlation Between Bruxism And Cervical Function

Bruxism is defined as an unconscious oral habit of dysfunctional rhythmic pressing, clenching and grinding of the teeth when performing movements that are not part of the masticatory function that leads to occlusal trauma and it is an oral parafunctional activity it is not related to normal physiological functions, such as speech, breathing, chewing and swallowing , and/or by bracing or thrusting of the mandible , and it accelerates abnormal tooth wear, periodontal disease, and temporomandibular disorders (TMD)

Bruxism should be considered a potential protective risk factor rather than a disorder in otherwise healthy individuals. In most persons bruxism is not a disorder, it is a sign of a disorder (e.g. in individuals with obstructive sleep apnea, epilepsy , being the ending episode of respiratory arousals, so as to prevent the collapse or restore the patency of the upper airway whilst asleep) , which would classify bruxism as an attribute that decreases the chance of a negative health outcome.

There is two distinct circadian manifestations, either occurring during wakefulness or during sleep. Awake bruxism is a semivoluntary masticatory muscle activity during wakefulness that is characterized clenching or grinding tooth and/or by bracing or thrusting of the mandible
