Craniomandibular dysfunction includes all functional disorders related to the temporomandibular joint (TMJ) and the muscles involved in its movement.
Its presentation is very varied: pain in the joint, clicking of the opening or closing, headaches (headaches), facial or cervical muscle contractions, limitation in opening, even blockage in opening or closing; earaches, acufenes (ear noises), atriction (wear) in the dental enamel, etc.
They are diagnosed on the basis of pathological changes in muscle and joint tissues (contractures, arthritis…), and are highly frequent in relation to episodes of stress.
Pathologies of craniomandibular dysfunction:
At a joint level: arthrosis, arthritis or arthralgia (joint pain) of the TMJ. Different degrees of dislocation of the joint disc accompanied by blockages in opening or closing.
At the muscular level: myalgia (myofascial syndrome) with or without opening limitation.
At the dental level: chronic pulpitis or even pulp necrosis in the teeth which suffer from overloading and wear of the enamel (bruxism). Inflammation of the dental ligament (periodontitis) due to overload (bruxism).
