“…The fact that certain neurotransmitters are implicated in bruxism, stress and anxiety (Bracha, Person et al, 2005;Mascaro et al, 2005;Nevid et al, 2003;Wood & Toth, 2001) underscores the problem and confirms the research findings of this study on the relations between these factors.…”

“…Results indicate that dopaminergic fibres may alter central nucleus of the amygdale (CeA) neurons which supply areas related to oral motor control (Mascaro, Bittencourt, Casatti, & Elias, 2005). In rats, stress induction led to an increase in dopaminergenic transmission in the striatum and parafunctional masticatory activity seems to reduce the amplitude thereof (Gomez et al, 1999).…”

“…This could play a role in bruxism. Oral facial movements may thus be regulated by catecholamines such as dopamine, through the premotor brainstem nuclei, which are related to masticatory control, and forebrain areas related to autonomic and stress response (Mascaro et al, 2005).…”

Introduction: Bruxism is an oral parafunctional habit involving clenching and grinding of the teeth that occurs mainly unconsciously, diurnally and nocturnally. It is considered an important contributory factor in the aetiology of myofascial pain (MFP) and temporomandibular disorders (TMD). The aetiology of bruxism is considered to be multifactorial, involving physiological and psychological factors. Statement of the problem: Do subthreshold symptoms of anxiety have an effect on bruxing behaviour? Aim: The aim of this study was to examine the relationship between the subthreshold symptoms (subtle, prodromal, atypical and subclinical symptoms of which the severity precludes diagnosis as a disorder) of anxiety and bruxism in a sample of subjects using a spectrum model. Method: Firstly, a self report screening measure consisting of the Spielberger State Trait Anxiety Inventory (SSTAI); the Kessler-10 (K-10); demographic and bruxism criteria were used to determine levels of anxiety, stress and bruxism on a continuum. Secondly, in order to determine a bruxism score, a standardized clinical examination; intra-oral photographs and dental casts were used in the study. Thirdly, the diagnosis of bruxism according to specified criteria was performed.Results: Forty one percent (n = 12) of the sample of 29 subjects was diagnosed as bruxers. A possible relation between subthreshold symptoms of anxiety, stress and bruxism was observed in the results. In approximately half of the subjects with higher than average anxiety and stress scores, bruxism behaviour was found. Clinical significance: The dentist could play a role in recognizing that a patient may be experiencing stress or anxiety, expressed through bruxing behaviour and refer the patient for therapy or counseling. The treatment of bruxism could be complimented by therapy or counseling which focuses on addressing the subthreshold symptoms of anxiety. Conclusions: An understanding of v the psychological factors involved in the aetiology of bruxism could encourage a more holistic approach to the treatment of bruxism.

“…ont tenté d'étudier les voies anatomiques pouvant exister entre le système dopaminergique et le noyau moteur du nerf trijumeau. Ils ont réussi à mettre en évidence des traces d'activité synaptique mettant en jeu des catécholamines, reliant le noyau moteur trigéminal à deux zones distinctes du cerveau [18] : l'aire prémotrice (ou aire psychomotrice), reliée au contrôle masticatoire, et des structures sous-corticales (amygdale et thalamus), liées au système nerveux autonome et aux réponses face au stress. Ainsi, ils apportent un argument anatomique à cette hypothèse dopaminergique ainsi qu'à l'étiologie psychologique et montrent que les catécholamines ont bien une action sur le contrôle neurophysiologique et neuropsychologique des mouvements orofaciaux.…”
