Assessment of Morphological Alterations of Temporomandibular Joint Articular Surfaces in Patients with Temporomandibular Dysfunction

Aim: to study morphometrically the peculiarities of remodeling of chondrocytes of the articular surfaces of the temporomandibular joint in hyperglycemia.Materials and methods: Quantitative morphological methods were used to study diameters of chondrocytes and their nuclei, nuclear-cytoplasmic relationship in these cells, relative volume of damaged chondrocytes, intercellular-chondrocytic relationship in mature chondrocytes of the articular surfaces of the temporomandibular joint of 45 laboratory mature white male rats with simulated diabetes.Results: A comprehensive analysis of the morphometric parameters presented in the article showed that they did not differ in the articular surfaces of the temporal fossa and mandibular head of the intact temporomandibular joint. The expressed structural changes of chondrocytes were revealed at a monthly and a two-month diabetic arthropathy of this joint.Conclusions: Proceeded studies and obtained results suggest that prolonged hyperglycemia leads to diabetic arthropathy of the TMJ, which is characterized by atrophy of chondrocytes, violation of nuclear-cytoplasmic relationships, an increase in the relative volume of damaged chondrocytes and volume of intercellular substance. The detected changes in quantitative morphological parameters depended on the duration of hyperglycemia and dominated in the cartilaginous tissue of the articular surface of the mandibular head.

The Mean

A total of 301 unselected orthodontic referrals were assessed for temporomandibular disorder, using a standardized questionnaire and clinical examination protocol. The mean age of the patients was 13·4 years. Over one-third of the 301 patients were found to exhibit at least one sign of TMD, and two-thirds had a mandibular dysfunction index (MDI) score of 1, 2 or 3, indicating mild to moderate. dysfunction. Only five patients were found to have severe temporomandibular dysfunction. Statistically significant relationships were found between patient age and mandibular opening, and temporomandibular joint noises. No relationship was found between signs detected by clinical examination and symptoms reported by the patients.

Temporomandibular Dysfunction

Dor miofascial é um distúrbio muscular que esta frequentemente associada às desordens temporomandibulares, afeta os músculos da mastigação e pode levar a limitações funcionais. Esta revisão sistemática tem como objetivo identificar a literatura científica sobre os efeitos do agulhamento seco superficial e profundo para o tratamento da dor em pacientes com disfunção temporomandibular (DTM) miofascial. Trata-se de uma revisão sistemática buscando estudos primários nas bases de dados PubMed e Biblioteca Virtual em Saúde - BVS (que reúne bases de dados como LILACS - Literatura Latino-americana e do Caribe em Ciências da Saúde, MEDLINE - Medical Literature Analysis and Retrieval System Online, SciELO - Scientific Electronic Library Online, dentre outras) com os descritores “temporomandibular joint disorders dry needling”, or “myofascial temporomandibular dysfunction dry needling”, or “temporomandibular dysfunction dry needling”, assim artigos inglês, português ou espanhol que respondem à questão norteadora de utilização do agulhamento seco no tratamento de DTM miofascial foram incluídos; teses, monografias, associações de tratamentos, artigos que estavam em outras línguas que não as citadas acima e revisões sistemáticas foram excluídas. Nove estudos foram considerados elegíveis. Um estudo comparou o agulhamento seco superficial e profundo. Quatro estudos utilizaram apenas agulhamento seco profundo e outros 4 estudos não especificaram o tipo de agulhamento utilizado. Diante disso, os resultados encontrados sugerem que não há dados suficientes para tirar conclusões sólidas sobre qual tipo de agulhamento seco é melhor para o tratamento da dor miofascial associada à DTM. Ensaios clínicos randomizados de baixo risco de viés são fortemente necessários.

The Common

Abstract Temporomandibular joint dysfunction is one of commonest joint that gets affected in females, studies shows that the altered posture of cervical spine lead to mandibular retrusion and hence in long term leads to Temporomandibular dysfunction, the tightness of sub-occipital muscle leads to pulling of the ligaments around the joint in course causing retrusion or malocclusion. The common symptoms of temporomandibular joint dysfunction includes clicking, reduced mouth opening, headache. Alteration in the function of TMJ leads to poor quality of life of the individual as this joint is involved in basic activities like talking, eating, laughing and kissing. The sub-occipital muscles are the group of muscle extending from spinous process of C2 vertebrae to inferior nuchal line of occipital bone. Tightness of this muscle lead to extension of upper cervical spine and flexion of lower cervical spine. The common causes of temporomandibular dysfunction includes injury to jaw, overuse, inflammatory condition like arthritis and bruxism. Our aim is to find out the efficacy of sub-occipital Myofacial Release versus conventional physiotherapy on functional disability of TMJ. The clinical trial registry-India(CTRI) registration number for this trial is CTRI/2021/05/033493.

Abstract Objective: To assess changes in the articular surfaces of the temporomandibular joint (TMJ) and in condylar translation, as detected by magnetic resonance imaging (MRI), determining whether such changes correlate with disc displacement. Materials and Methods: We retrospectively analyzed the MRI scans of 2076 TMJs of 1038 patients with symptoms of temporomandibular disorder. We attempted to determine whether articular disc deformity and changes in condylar translation, as well as changes in the articular surfaces of the condyle, glenoid fossa, and articular eminence, correlated with disc displacement. Results: Disc displacement with reduction was associated with changes in the shape of the articular eminence. Disc displacement without reduction was most strongly associated with disc deformity, condylar degeneration, glenoid fossa degeneration, and effusion. Neither decreases nor increases in condylar translation were associated with disc deformity, degenerative bone changes, or disc displacement. Conclusion: Changes in the shape of the articular eminence seem to predispose to progression of internal derangement of the TMJ.
