Dental trismus is caused by an injury to the masticatory muscles, such as opening the jaw for an extended period of time or having a needle pass through a muscle. Typical dental anesthesia for the lower jaw involves inserting a needle into or through a muscle.
The 2 parts of lateral pterygoid have different actions. The lower head contracts during mouth opening, and the upper head contracts during mouth closing. The function of the lower head is to steady the articular disc as it moves back with the condyle into the articular fossa. It is relaxed during mouth closure. [27]
Orthodontics can address malocclusion without surgery, but this is often unstable or compensatory, and fails to address the aesthetic impacts of condylar degeneration. Orthognathic surgery in conjunction with orthodontics may be done to reconstruct and stabilize the condyles and disc of the temporomandibular joint.
Dislocation can occur following a series of events if the jaw locks while open or unable to close. If the jaw is dislocated, it may cause an extreme headache or inability to concentrate. When the muscle's alignment is out of sync, a pain will occur due to unwanted rotation of the jaw. [4] If the pain remains constant, it may require surgery to ...
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

Oral and maxillofacial surgery: Symptoms: Exposed bone after extraction, pain: Complications: Osteomyelitis of the jaw: Usual onset: After dental extractions: Duration: Variable: Types: Stage 1-Stage 3: Causes: Medications related to cancer therapy, and osteoporosis in combination with dental surgery: Risk factors
After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
The result is a transient facial paralysis, with the injected side of the face having temporary loss of the use of the muscles of facial expression that include the inability to close the eyelid and the drooping of the labial commissure on the affected side for a few hours, which disappears when the anesthesia wears off.
