Trismus is defined as painful restriction in opening the mouth due to a muscle spasm, [5] however it can also refer to limited mouth opening of any cause. [6] Another definition of trismus is simply a limitation of movement. [4] Historically and commonly, the term lockjaw was sometimes used as a synonym for both trismus [2] and tetanus. [7]
pain is precipitated by jaw movements or chewing of hard or tough food; reduced range of or irregular jaw opening; noise from one or both TMJs during jaw movements; tenderness of the joint capsule(s) of one or both TMJs; D. Headache resolves within 3 months, and does not recur, after successful treatment of the TMJ disorder
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 ...
Condylar resorption, also called idiopathic condylar resorption, ICR, and condylysis, is a temporomandibular joint disorder in which one or both of the mandibular condyles are broken down in a bone resorption process.
The inferior compartment allows for rotation of the condylar head around an instantaneous axis of rotation, [14] corresponding to the first 20mm or so of the opening of the mouth. After the mouth is open to this extent, the mouth can no longer open without the superior compartment of the temporomandibular joints becoming active.
Procedures for root canal. The space inside the root canals is filled with a highly vascularized, loose connective tissue, called dental pulp. The dental pulp is the tissue of which the dentin portion of the tooth is composed. The dental pulp helps complete formation of the secondary teeth (adult teeth) one to two years after eruption into the ...
Root canal treatment should be performed on the tooth if it is determined that previous therapy was unsuccessful. Removal of the necrotic pulp and the inflamed tissue as well as proper sealing of the canals and an appropriately fitting crown will allow the tooth to heal under uninfected conditions.
[2] [3] [4] Ankylosis occurs when partial root resorption is followed by repair with either cementum or dentine that unites the tooth root with the alveolar bone, usually after trauma. [5] However, root resorption does not necessarily lead to tooth ankylosis and the causes of tooth ankylosis remain uncertain to a large extent. [5]
