Occlusal features are not discriminant factors in the occurrence of temporomandibular disorders. Also, it cannot be concluded that the longer the patients have temporomandibular disorders, the higher their pain scores will be.

SUMMARYInternal derangement of the temporomandibular joint (TMJ) can be defined as a disorder of the intracapsular components of the joint, which is originated by displacement of the disc from its normal functional relationship with the condyle of the mandible and the temporal bones articular fossa. The most common symptoms of temporomandibular joint internal derangement vary from simple joint sounds to locking and pain. The aim of this case series is to evaluate the effects of GowGates anaesthesia technique, which blocks the auriculotemporal nerve, in combination with an intracapsular local anaesthetic injection, on patient comfort during artrocenthesis. 24 patients had arthrocentesis due to temporomandibular disorder complaints. We suggest that further studies might give more information about the patient comfort during artrocenthesis. Internal derangement of the temporomandibular joint (TMJ) the most common form of temporomandibular disorders. It affects patient's daily life with pain, dysfunction, joint sounds, and even aural symptoms.

Abscess of the infratemporal fossa is a rare complication which can be difficult to diagnose. It occurs mostly due to dental infection, tooth extraction, fractures and/or infections involving the maxillary sinus. This condition can be life threatening if not dealt with immediately. The maxillofacial surgeon must be aware of the symptoms and clinical findings of the infection of the infratemporal fossa in order to initiate the treatment as soon as possible. In this case report, a patient with an infratemporal fossa infection presenting with an unusual symptom of inferior alveolar nerve involvement is presented.
