Bruxism is a controversial phenomenon. Both its definition and the diagnostic procedure contribute to the fact that the literature about the aetiology of this disorder is difficult to interpret. There is, however, consensus about the multifactorial nature of the aetiology. Besides peripheral (morphological) factors, central (pathophysiological and psychological) factors can be distinguished. In the past, morphological factors, like occlusal discrepancies and the anatomy of the bony structures… 

Drugs and bruxism: a critical review.

Although certain substances related to the dopaminergic, serotonergic, and adrenergic systems suppress or exacerbate bruxist activity in humans and animals, the literature is still controversial, and based mostly on anecdotal case reports.

Influence of genetics and biopsychosocial aspects as etiologic factors of bruxism

The role of genetic and environmental factors in the phenotypic variance of bruxism in a large population of young-adult twins in Finland was examined, and a substantial genetic component regarding the variation of sleep-related Bruxism was found, and no gender difference was found.

It is concluded that to date, there is no evidence whatsoever for a causal relationship between bruxism and the bite.

Psychic and occlusal factors in bruxers.

It can be confirmed that certain psychic traits are present in bruxers, while occlusal factors are not useful parameters to discern bruxer from non-bruxers.

Findings indicate that there was a decrease of cortical activation pattern in patients with bruxism in clenching tasks, which indicates decreased blood flow and activation in regional neuronal activity.

Do bruxism and temporomandibular disorders have a cause-and-effect relationship?

It is concluded that the relationship between bruxism and temporomandibular disorders is still unclear and future research should examine longitudinal epidemiologic and clinical/experimental data to establish or refute a cause-and-effect relationship.

SB subjects were observed to present vigilance-sleepiness and somatic problems, however, they are generally good sleepers and no abnormalities of the autonomic nervous system could be shown in awake SB subjects.

Nocturnal bruxism and temporomandibular disorders.

Nocturnal bruxism is believed to be a stress-related sleep disorder, occurring in both men and women, in children, and in adults, and its relation to disorders of the masticatory system and headaches is discussed.

Bruxisma related to levodopa therapy.

The abnormal involuntary movements that result from levodopa therapy frequently appear in the face, lips, and tongue and are often termed "mouthing" movements, which are a limiting factor in dosage.

Sleep Bruxism: Validity of Clinical Research Diagnostic Criteria in a Controlled Polysomnographic Study

Polysomnographic recordings from 18 bruxers and 18 asymptomatic subjects were analyzed to discriminate sleep bruxism from other orofacial motor activities and to calculate sensitivity, specificity, and predictive values of research criteria.

Occlusal Disharmonies Modulate Central Catecholaminergic Activity in the Rat

Experimental evidence is provided of a modulation of central catecholaminergic neurotransmission by occlusal disharmonies, being dependent on the nature of the incisal alteration and on the time during which it was maintained.

The results partially support the role of the central dopaminergic system in bruxism and suggest that stress, in general, may not be a relevant factor in tooth wear.
