###### Abstract  
Current neuroanatomical evidence showed the anatomical relationship between the temporomandibularibular joint innervation with the vestibular system. However, there is no clear evidence regarding if temporomandibularibular disorders are associated with balance impairments. Therefore, the aims of this study were to assess the clinical relevance of stabilometric features in populations with temporomandibularibular disorders and to analyze the influence of the mandibular position and visual inference in the balance scores in both healthy and clinical populations. This observational study was conducted in one sample of healthy controls and one sample with temporomandibularibular disorders. Sociodemographic data (age, gender, height, weight, body mass index, and foot size), clinical data (presence or absence of temporomandibularibular disorders) and stabilometric data under six different conditions were collected. Sixty-nine subjects (43.5% male; 36.2% patients) were assessed. No differences between Temporomandibularibular disorders and healthy groups were found in any stabilometric outcomes, unlike oscillation area with closed eyes and medium interscuspidal position (\(p<0.01\)). Although visual feedback showed to be relevant (\(p<0.0001\)), mandibular position produced no differences in any stabilometric measurement (\(p>0.05\)). This study found that healthy subjects and patients with temporomandibularibular disorders showed no balance differences in the stabilometric outcomes assessed. Although visual input played an important role in the balance, mandibular position seems to be irrelevant. t 17 March 2021 12 May 2021 14  
masticatory muscle receptors such as the neuromuscular spindle, Golgi tendon organs, periodontal ligament receptors, and the TMJ free nerve endings) with the vestibular nuclei and trigeminocerebellar links, the importance of these inferences still unclear [6; 7]. In fact, recent studies showed that induced changes in the dental occlusion had a positive effect on the neuromuscular coordination and balance [8; 9]. The stomatalngathic system (characterized by the maxilla and mandible, dental arches, soft tissues, temporomandibular joint--TMJ, masticatory muscles, and orofacial nerves) is a functional unit that shows muscular and ligamentous connections to the cervical region [5; 10]. In fact, associated TMD comorbidities including neck pain and headache [11] showed altered balance compared with healthy populations since cervical spine have important connections to the vestibular and visual systems [12; 13]. Therefore, the trigeminal inferences to the vestibular system could be regulated by the tonic motricity of the mandible muscles and infer on the fine regulation of orthostatic posture [14]. Although potential associations between balance and temporomandibular joint (TMJ) have been assessed in several studies [14; 15; 16; 17], most of the studies were conducted in healthy populations. Up to our knowledge, specific evidence regarding the clinical relevance of different standing balance parameters in TMD populations is lacking. Several clinical tests have been proposed to evaluate postural control, including the Romberg test, the Timed Up and Go, the Berg Balance Score, the Tinetti Scale, the Functional Reach Test, or the BESTest (Balance Evaluation Systems Test) [18]. However, since these tests are based on qualitative and subjective aspects of the evaluation and the current opinion of clinicians is to focus on those clinical instruments with acceptable utility (e.g., validity, reliability, specificity, and sensitivity) [19], alternative methods providing objective, valid and reliable data are needed. Stabilometry is an objective, reliable, and one of the most widely instrument used in clinical practice for studying several balance features associated with functional disorders of the vestibular system [20].
