Incidence of dental barotrauma and temporomandibular joint problems of divers in Turkey
CONCLUSION: In our study, the localization of barodontalgia was consistent with the distribution of caries and restored tooth areas in the literature. Dive-related TMJ pain was also more common in those with pre-dive problems such as bruxism and joint noise. Our results are important to remind us of the necessity of preventive dentistry practices and early diagnosis of problems in divers. Divers should take personal precautions, such as brushing their teeth twice a day and avoiding the need for urgent treatment. The use of a personalized mouthpiece is also recommended for divers to prevent dive-related temporomandibular jo...

Intra-articular injection of kartogenin promotes fibrocartilage stem cell chondrogenesis and attenuates temporomandibular joint osteoarthritis progression
Introduction: Kartogenin (KGN) is a small-molecule compound that has been reported to improve the chondrogenic differentiation of mesenchymal stem cells in vitro and to alleviate knee joint osteoarthritis in animal models. However, whether KGN has any effect on temporomandibular joint osteoarthritis (TMJOA) remains unclear.Methods: We first performed partial temporomandibular joint (TMJ) discectomy to induce TMJOA in rats. Histological analysis, tartrate-resistant acid phosphatase staining, and immunohistochemistry were used to assess the therapeutic effect of KGN on TMJOA in vivo. CCK8 and pellet cultures were used to det...

Effect of the magnitude of condylar head displacement on the TMJ function in skeletal Class II patients undergoing different degrees of mandibular advancement: A retrospective Comparative Study
This study aimed to compare the condylar head displacement (CHD) after bilateral sagittal split ramus osteotomy (BSSO) between different degree mandibular advancement in skeletal Class II patients and to evaluate whether the TMJ function would be affected.

Effect of Single dose of Methylprednisolone Injection at Stylomandibular Ligament Insertion on Pain and Various Mandibular Movements Among Patients with Ernest Syndrome: A Pilot Study
AbstractInsertion tendinosis of stylomandibular ligament or Ernest syndrome is a rarely encountered cause of orofacial pain. The pain in this disorder originates from the stylomandibular ligament insertion site and radiates to the temporomandibular joint (TMJ), neck, shoulder, and periauricular region. Ten subjects who had undergone surgery for mandible fractures diagnosed with Ernest syndrome were considered for the present study. The origins and insertions of the stylomandibular ligament were marked and palpated using fingertip and blunt probe. The Ernest syndrome was confirmed by injecting diagnostic local anesthesia in...

Incidence of Orofacial Manifestations of Juvenile Idiopathic Arthritis From Diagnosis to Adult Care Transition: A Population ‐Based Cohort Study
ConclusionOrofacial signs and symptoms were frequent findings in children and adolescents with JIA. TMJ involvement was seen in 30.1% of the cohort; and 20.6% of the total cohort developed JIA-related dentofacial deformity before transition into adult care. This is the first population-based study in the era of available biologic treatments to document these frequent orofacial complications in children with JIA.

Assessment of temporomandibular joint disc position and skeletal stability after bimaxillary surgery
ConclusionThis study suggested that TMJ disc position, including ADD, could not affect skeletal stability, including the maxilla and distal segment after bimaxillary osteotomy, and short-term relapse could be related to the movement amount or angle change by surgery for all measurements.

Temporomandibular Joint Replacement Using Stock Alloplastic Graft in the Treatment of Ankylosis: A Case Report
CONCLUSION: Stock TMJR devices are an effective and viable option for the treatment of re-ankylosis. This ensures almost immediate possibility of physiotherapy and long-term results including maintenance of mouth opening and function. Osteoarticular TB can cause trismus and painful joints which may be misdiagnosed. Any patient with reduced mouth opening with a history of TB should be investigated for possible extrapulmonary TB.PMID:37272143 | DOI:10.5005/jp-journals-10024-3489

A nonsurgical treatment strategy for longstanding, nonreducible, bilateral temporomandibular joint dislocation: A case report
Temporomandibular joint (TMJ) dislocation is a condition in which the mandibular condyle is displaced from the glenoid fossa and must be manipulated to return it to its normal position. Among several diagnostic subtypes, long-standing or chronically protracted TMJ dislocation is rare and challenging to manage. Treatment options include various nonsurgical and surgical approaches. This case report describes the successful nonsurgical management of a longstanding bilateral TMJ dislocation using elastic traction with a removable appliance and posterior bite planes.

Which comorbid conditions and risk factors affect the outcome of and progression to total temporomandibular joint replacement?
Surgery is an effective modality to reduce pain and increase range of motion (ROM) in TMJ disorders. The aim of this study was to determine which comorbidities and risk factors affect outcomes and progression to total joint replacement (TJR). A retrospective cohort study of patients who underwent TJR between 2000- 2018 at MGH was conducted. Primary outcome was successful vs unsuccessful surgery. Success was defined as pain score ≤ 4 and ROM ≥ 30 mm; failure was defined as lack of either or both.
