11/162. Bleaching and temporomandibular disorder using a half tray design: a clinical report. A maxillary soft, custom-fitted tray was fabricated for a patient to perform nightguard vital bleaching. Treatment was interrupted after the patient experienced pain in the temporomandibular joint area shortly after wearing the bleaching prosthesis. The tray was trimmed so the labial, incisal and buccal cusps were covered and Sc) the patient had complete tooth-to-tooth contact in the maximum intercuspal position. The prosthesis proved to be retentive even without the presence of the bleaching material. The thick, sticky bleaching material was contained in the half tray design and the tray was held in place. The patient was able to continue the bleaching process for the 2-week duration necessary to achieve successful lightening of the teeth without further TMD symptoms. ( info) |
12/162. Extradural haematoma following temporomandibular joint arthrocentesis and lavage. We describe a case of a 59-year-old woman who remained drowsy and developed a left hemiparesis following right temporomandibular joint (TMJ) arthrocentesis and lavage for TMJ dysfunction. CT demonstrated an extradural haematoma. This is the first reported case of an extradural haematoma following TMJ arthrocentesis. ( info) |
| OBJECTIVE: neoplasms of the temporomandibular joint (TMJ) usually mimic common causes of TMJ syndrome, leading to delay in diagnosis. To increase awareness of TMJ neoplasms and establish guidelines for early intervention, we performed a retrospective analysis of a series of patients with neoplasms of the TMJ. STUDY DESIGN AND SETTING: A retrospective review of the records of patients with neoplasms of the TMJ from 1990 to 1997 was done. RESULTS: Six patients were identified. The neoplasms included benign and malignant neoplasms. The time from initial presentation to final diagnosis was in most cases prolonged, ranging from 3 months to 8 years. patients typically showed advanced lesions radiographically. All patients required surgical extirpation. Postoperative radiation therapy was used for malignant lesions. Patient outcomes were delineated. CONCLUSIONS AND SIGNIFICANCE: neoplasms, both benign and malignant, of the TMJ are rare but represent a challenging diagnostic problem. In patients with 1 month or more of recalcitrant TMJ swelling or pain, radiographic imaging may be considered to rule out these rare neoplasms. This may lead to earlier intervention and improved outcome. ( info) |
14/162. Unhealed extraction sites mimicking TMJ pain. A case of unhealed extraction sites in the mandible is described, including clinical, radiographic, and biopsy findings. The subject was treated for TMJ disease in the past but still had related signs and symptoms and facial pain. ( info) |
15/162. arthrogryposis multiplex congenita in a patient with limited mouth opening: a case report. This report describes a case of arthrogryposis multiplex congenita and concomitant bruxism with limited mouth opening and pain in the temporomandibular joints (TMJ). A conservative treatment with a myorelaxing splint and physiotherapeutic exercises was prescribed resulting in improvement to the muscular and joint conditions and a reduction in pain. ( info) |
16/162. tooth wear and loss: symptomatological and rehabilitating treatments. The authors report a clinical case that presented tooth wear and absence, with painful muscular and articular symptomatology, and also alteration in deglutition, mastication and speech. The clinical procedures used were re-establishment of vertical dimension of occlusion, mandibular centric relations, and occlusal contacts through therapeutic removable partial dentures. The condyle position was analyzed in habitual occlusion and in occlusion with dentures, through transcranial radiographs of the temporomandibular joints. Oral rehabilitation was achieved with dental restoration and removable partial dentures. ( info) |
17/162. Extensive temporal bone pneumatization: incidental finding in a patient with TMJ dysfunction. An 18-year-old male presented with symptoms of temporomandibular joint dysfunction. A panoramic radiograph revealed slight erosion of the condylar heads, and an incidental finding of multilocular radiolucencies in the zygomatic processes of the right and left temporal bones. CT scans were undertaken to exclude any sinister cause. The radiolucencies were shown to be extensive bilateral pneumatization of the temporal bones. Conservative management relieved the symptoms of TMJ dysfunction. ( info) |
18/162. Modified retrograde intubation in a patient with difficult airway. We report a modified technique of retrograde endotracheal intubation in a patient with limited motility at the atlanto-occipital joint, temporomandibular joint, and cervical spine, presenting for closure of a large oronasal fistula. Despite more recent advances in intubation techniques and technology, retrograde intubation still deserves a place in the anesthetist's armamentarium for the management of the difficult airway.

19/162. Rheumatological complications associated with the use of indinavir and other protease inhibitors. Several cases are reported of rheumatological pathology (temporomandibular dysfunction, frozen shoulder, Dupuytren's disease, and tendinitis) most probably related to the intake of indinavir in hiv positive patients. A survey using an anonymous questionnaire of 878 people with hiv infection treated with antiretroviral drugs suggests that other protease inhibitors may also cause arthralgia. ( info) |
20/162. Spontaneous regression of bilateral dentigerous cysts associated with impacted mandibular third molars. A case is described where a routine panoramic radiograph revealed radiolucencies, compatible with dentigerous cysts, associated with the crowns of bilateral impacted lower third molars. Both cysts had regressed in a follow up radiograph three years later with no intervention. This is the first reported case of spontaneous regression of bilateral dentigerous cysts. ( info) |
