Emotional stress (anxiety, depression, anger) may increase pain by causing autonomic, visceral and skeletal activity and by reduced inhibition via the descending pathways of the limbic system. The interactions of these biological systems have been described as a vicious "anxiety-pain-tension" cycle which is thought to be frequently involved in TMD.
Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
OMD in adult and geriatric populations are due to various neurological impairments, oral hygiene, altered functioning of muscles due to aging, systemic diseases, etc. Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth ...
More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest. Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving.
As explained in a 2008 study, in people with mood disorders there is a dynamic link between their mood and the way they move. [6] People showing signs of psychomotor agitation may be experiencing mental tension and anxiety, which comes out physically as: fast or repetitive movements; movements that have no purpose; movements that are not ...
Temporomandibular joint pain is generally due to one of four reasons. Myofascial pain dysfunction syndrome, primarily involving the muscles of mastication. This is the most common cause. Internal derangements, an abnormal relationship of the disc to any of the other components of the joint. Disc displacement is an example of internal derangement.
While anxiety can take many forms, one of the more troubling symptoms is chest tightness, which can also be a sign of something more immediately life-threatening, like a heart attack.
Anaesthetic injected near the mandibular foramen to block the inferior alveolar nerve and the nearby lingual nerve (supplying the tongue). This causes loss of sensation on the same side as the block to: the teeth (inferior alveolar nerve block) the lower lip and chin (mental nerve block) front two-thirds of the tongue (lingual nerve block).
