Oromandibular dystonia (OMD) is an uncommon focal neurological condition affecting the jaws, face, and mouth. [1] 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.
Signs and symptoms of temporomandibular joint disorder vary in their presentation. The symptoms will usually involve more than one of the various components of the masticatory system, muscles, nerves, tendons, ligaments, bones, connective tissue, or the teeth. [23] The three classically described, cardinal signs and symptoms of TMD are: [11] [24]
Bruxism may cause a variety of signs and symptoms, including: View from above of an anterior (front) tooth showing severe tooth wear which has exposed the dentin layer (normally covered by enamel). The pulp chamber is visible through the overlying dentin. Tertiary dentin will have been laid down by the pulp in response to the loss of tooth ...
The signs and symptoms for patients can be varied mainly depending on the growing state of teeth (permanent or deciduous). Other factors, such as age, sex, site of infection may also lead to the occurrence of specific signs and symptoms, but their roles are not well-studied and evaluated.

Generally all gingival diseases share common features such as signs and symptoms being restricted to gingiva, clinically detectable inflammation, and the potential for the gum tissues to return to a state of health once the cause is removed, without irreversible loss of attachment of the teeth. [4]
Clinically, both the baby (primary) and adult (permanent) teeth often appear amber coloured and translucent, and show signs of severe attrition. Primary teeth have a more obvious appearance as they have a thinner layer of enamel overlying dentine, hence the abnormal color of dentine is more noticeable.
Episodic symptoms of DH is the likely reason why some patients fail to report the discomfort. [16] Hence having a negative effect on the number of diagnoses. If a patient does not complain of the symptoms then no additional screening checks are in place for dentin hypersensitivity and often the diagnosis is missed.
