Abstract:
Osteogenesis imperfecta is a heterogeneous group of hereditary disorders of connective tissue diseases characterized by increased bone fragility, low growth, sometimes accompanied by abnormalities within the dentine, blue sclera, and partial or total hearing impairment. The changes may affect all joints, including the cervical spine and temporomandibular joints in the future, resulting in pain. The aim of the present study was to assess whether there is a relationship between the active range of motion of the cervical spine and the mobility of temporomandibular joints due to differential diagnosis in children with osteogenesis imperfecta, and to present a prevention algorithm for temporomandibular disorders. The study involved a group of 34 children with osteogenesis imperfecta, and the control group included 23 children (age 9.1 ± 3.8 years). Data were collected through an interview based on the author’s questionnaire, and the physical examination consisted in measuring the mobility of the cervical spine using an inclinometer (Cervical Range of Motion Instrument), the Helkimo scale, and linear measurements. In children with congenital bone fragility, there were acoustic symptoms from the temporomandibular joints more often than in healthy children. A correlation was found between the mobility of the cervical spine and temporomandibular joints in the study group. In the case of detecting irregularities in the temporomandibular joints, children were ordered to perform jaw-tongue coordination exercises.

Abstract:
Introduction. Pathology of the temporomandibular joints (TMJ) is widespread even among young people, and the frequency of its occurrence increases with the age of patients. In this case, there is violated one of the main characteristics of the joints — mobility, which is measured by the mouth opening width (MOW). There is not enough information in the literature on the age and sex characteristics of the TMJ mobility in individuals without pathology of this joint.The aim of the study is to research the mobility of the TMJ in different age groups in men and women without pathology of this joint.Materials and methods. There were examined 714 patients who applied for dental care, aged 20 to 79 years (504 women and 210 men), without pathology of the TMJ. The range of motion in the TMJ was measured using a caliper with thin lips during the opening of the mouth in a neutral head position. The subjects were divided into age groups: 20–29, 30–39, 40–49, 50–59, 60–69 and 70–79 years old.Results. It was found that the most common MOW value was 4,9 cm (range from 4,5 to 5,2 cm). A distribution of relative frequencies corresponding to the normal Gaussian distribution was observed for this indicator. The mobility of the TMJ changed little with age. Analysis of the distribution of temporomandibular joint mobility by age groups of patients with a step of 10 years showed the similarity of the average MOW values in all groups of subjects, except for the group of 20–29 years. Their average values (4,75 cm) were lower than those of the other groups (4,9 cm, p<0,05). It was found that men have a higher mobility of the TMJ compared to women in all age groups (on average by 0,28 cm, p<0,05).Conclusion. Mouth opening widths of 4,6 to 5,2 cm (average 4,9 cm) can be considered as normal. TMJ mobility is not related to age. Consequently, a decrease in the mobility of the TMJ in persons of older age groups cannot be considered as normal age-related changes. TMJ mobility depends on sex. Men have higher TMJ mobility than women in all age groups. Thus, the TMJ differ from other joints not only in their complexity (two joints always work together), but also in age and sex patterns of mobility.

Abstract:
This study aimed to assess possible associations between the following factors: articular disc anatomy and position; articular eminence and condyle morphology; presence of joint effusion; condyle mobility; and lateral pterygoid muscle insertion pattern. Magnetic resonance images of 33 joints of symptomatic patients were assessed. The articular disc was classified as normal, elongated, or folded; displacement was classified as normal, lateral, or medial; the condyle was classified as rounded, convex, flattened, or angulated; the articular eminence was classified as box, sigmoid, flattened, or deformed; condyle mobility was classified as normal, hypomobile, or hypermobile; and the lateral pterygoid muscle insertion pattern was classified as Type I, Type II, or Type III. The most frequent forms of articular disc, articular eminence, and condyle were folded, flattened, and flattened, respectively. There can be a relationship connecting TMJ mobility with a normal disc form (100%); TMJ hypomobility with a folded disc form (48%); and TMJ hypermobility with an elongated disc form (100%). Magnetic resonance imaging allowed the clear observation of articular structures, and no association was found between insertion pattern and sideways disc position, disc form, and condyle form. All cases with joint effusion were related to hypomobility (100%).

Abstract:
OBJECTIVE: It has been shown that the temporomandibular joint is frequently affected by juvenile idiopathic arthritis, and this degenerative disease, which may occur during facial growth, results in severe mandibular dysfunction. However, there are no studies that correlate oral health (tooth decay and gingival diseases) and temporomandibular joint dysfunction in patients with juvenile idiopathic arthritis. The aim of this study is to evaluate the oral and facial characteristics of the patients with juvenile idiopathic arthritis treated in a large teaching hospital. METHOD: Thirty-six patients with juvenile idiopathic arthritis (26 female and 10 male) underwent a systematic clinical evaluation of their dental, oral, and facial structures (DMFT index, plaque and gingival bleeding index, dental relationship, facial profile, and Helkimo's index). The control group was composed of 13 healthy children. RESULTS: The mean age of the patients with juvenile idiopathic arthritis was 10.8 years; convex facial profile was present in 12 juvenile idiopathic arthritis patients, and class II molar relation was present in 12 (P = .032). The indexes of plaque and gingival bleeding were significant in juvenile idiopathic arthritis patients with a higher number of superior limbs joints involved (P = .055). Anterior open bite (5) and temporomandibular joint noise (8) were present in the juvenile idiopathic arthritis group. Of the group in this sample, 94% (P = .017) had temporomandibular joint dysfunction, 80% had decreased mandibular opening (P = 0.0002), and mandibular mobility was severely impaired in 33% (P = .015). CONCLUSION: This study confirms that patients with juvenile idiopathic arthritis a) have a high incidence of mandibular dysfunction that can be attributed to the direct effect of the disease in the temporomandibular joint and b) have a higher incidence of gingival disease that can be considered a secondary effect of juvenile idiopathic arthritis on oral health.

Abstract:
Temporomandibular disorders are a set of musculoskeletal dysfunctions within the masticatory system, with multiple etiologies. OBJECTIVE: Since craniocervical dystonia can involve the same neuromuscular structure as the temporomandibular joint, we sought to assess the correlation between temporomandibular disorders and craniocervical dystonia. METHOD: We applied the Research Diagnostic Criteria for Temporomandibular Disorders to 42 patients with craniocervical dystonia, in order to identify orofacial pain and temporomandibular characteristics on the day of botulinum toxin injection. RESULTS: Twenty-two patients (52.3%) reported temporomandibular joint pain; 24 (57.1%), joint sounds; 20 (47.6%), masticatory muscle pain; and 21 (50%), diminished jaw mobility. The patients with oromandibular dystonia presented temporomandibular disorders more frequently than did patients with other types of craniocervical dystonia (p<0.001). CONCLUSION: Temporomandibular disorders occur frequently in patients with oromandibular dystonia. Further studies should address the proper treatment of temporomandibular disorders associated with dystonia.

Objective: To investigate the effectiveness of exercise therapy on pain, function, and mobility outcomes in patients with temporomandibular joint dysfunction. Study design: Systematic review with meta-analysis. Methods: A systematic review and meta-analysis undertaken following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that met the inclusion criteria: (1) randomized controlled trials; (2) a population with the diagnosis of temporomandibular joint dysfunction; and (3) interventions that included exercise therapy were considered for review. When studies demonstrated homogeneity on outcome measures, the mean differences or standardized mean differences with 95% confidence interval were calculated and pooled in a meta-analysis for pooled synthesis. Results: Six articles with a total of 419 participants were included in the review and only four studies were included in the meta-analysis. Mobility and mixed exercise therapy approaches appear to be the most common exercise approaches utilized for management of temporomandibular joint dysfunction. Exercise therapy and the associated dosage provide moderate short-term and varying long-term benefits in reduction of pain and improvement of range of motion of the in patients with temporomandibular joint dysfunction. Conclusion: Included studies suggest a mobility or a mixed approach to exercise therapies have impact on reducing pain, significant impact for increasing range of motion, but lack a significant impact for functional improvement. Level of evidence: Therapy, level 1a-.

Abstract:
Introduction: Arthrogryposis multiplex congenita is not a disease but a term describing multiple congenital contractures. Etiological factors include neurological and primary myogenic diseases. This rare syndrome is present at birth and is characterized by reduced mobility of many joints. The contractures involve two or more joints with ankylosis. The accompanying musculature is hypoplastic, but multiple pterygia are also present. Arthrogryposis multiplex congenita is a heterogeneous group of disorders with the incidence rate of 6.2/100000 liveborn infants. The true incidence cannot be established, because many cases result in spontaneous miscarriages or stillbirth. More than 90% of cases are associated with birth defects. The cause of this syndrome is unknown. Many forms are not hereditary, though there are hereditary forms as well. Case report. This paper presents a case with arthrogryposis multiplex congenita. The pregnancy was not controlled regularly. During the pregnancy, oligohydramnion was detected. Due to contractures, labor ended is cesarean section. The child was born in the 34th week of gestation. Flexion and extension joint contractures were observed. Active and passive mobility of the afflicted joints was reduced. There was a limited motor function in the shoulder, elbow and wrist joints with a slight internal rotation of the shoulder joint and lower arm joints during pronation. The hips were subluxated; the feet were in equinovarus position and the fingers in ulnar deviation with partial syndactyly of the 4th and 5th fingers on the left hand. The infant had abnormal dermatoglyphics. The neck was short, and the 2nd and 3rd cervical vertebrae were fused. There was also a slight left-sided thoracic scoliosis. Trismus was present due to the existing ankylosis of the temporomandibular joint. The karyotype was normal. The serum creatinine phosphokinase was slightly elevated. The electromyographic picture indicate non-specific signs of myopathy. Discussion and conclusion. This is a case report of a "stiff joint syndrome". Due to the fact that data from the family history were unavailable, we could not establish the type of syndrome. However, heredity, growth and development at later age, as well as IQ, might significantly help in definite differentiation of this syndrome. In pregnancy, oligohydramnion should indicate more detailed ultrasonographic examination, as ankylosed joints can be detected in utero. .

Abstract:
Includes bibliographical references. Temporomandibular joint (TMJ) pain and dysfunction occurs commonly in the general population. Various surgical procedures have been used in the management of those patients who have not responded to conservative measures. Research into the surgical management of TMJ dysfunction and pathology has been restricted due to the lack of a suitable animal model. This study was undertaken initially to develop the sheep as an animal for TMJ research. The study has shown that Australian Merino sheep, with a TMJ broadly similar in size to humans, provides a satisfactory experimental model for TMJ research.

Abstract:

The temporomandibular joint (TMJ) complex consists of the condyle, articular eminence, and articular disc. This disc divides the intracapsular components of the joint into upper and lower joint spaces. Magnetic resonance imaging (MRI) is considered the reference standard for soft tissue diagnosis of the TMJ. One aim of the study was to identify if an association exists between arthralgia of the TMJ and MRI identified joint effusion.

The clinical significance of identifying the presence of TMJ effusion on MRI lies in its potential association with inflammation, clinically assessed as pain at the lateral TMJ pole or around the pole area. Unfortunately the literature has been divided in asserting whether pain in the joint area is associated with the presence of MRI assessed effusion. A systematic review of the literature was unable to provide conclusive evidence for or against an association between TMJ pain and effusion.

Materials and methods: Clinical and imaging findings from 336 joints were obtained from a historical cohort involving individuals with temporomandibular disorders. Two by two tables of association were used to determine if clinical signs associated with arthralgia were associated with the presence of ipsilateral effusion in the TMJ. These clinical signs included pain on range of motion (maximum unassisted and assisted opening as well as excursive movements), TMJ manipulation (compression and translation), and palpation of the lateral pole of the TMJ and around the TMJ pole. In addition, a total pain score (range 0-7) was created which represented the sum of positive responses to pain on any of the clinical range of motion tests. Statistical testing included the T-test to test for possible association of joint effusion with any pain to these clinical measures.

Results: Statistical tests of association between joint effusion and range of motion, excursions, protrusion, joint manipulation and palpation all had p values > .05.

Conclusion: The results suggest that there is no statistically significant association between an MRI diagnosis of joint effusion and TMJ arthralgia.

Abstract:
Joint mobility is dependent on comfort, thus pain is associated with mobility. This study examined the relationship between pain perception and joint mobility in arthritis patients before and after total knee arthroplasty. Pain perception was indicated by pain intensity, pain distress and pain expectation; joint mobility was represented by the degree of knee joint flexion. Visual analogue scales were used for pain intensity, pain distress and pain expectation; knee joint flexion as measured using a goniometer. Data were collected on 24 subjects preoperatively (T1), immediately postoperatively (T2) and forty-eight to seventy-two hours postoperatively (T3). Twenty-four subjects participated in the study. Significant paired t-test resulted for joint flexion at T1 and T3 and pain expectation at T2 and T3. Pearson product-moment correlation coefficients were significant for pain intensity and pain distress at all three times, pain intensity and joint flexion at T1 and pain intensity at T1 and at T2.

Abstract:
This thesis will be organized into three chapters discussing the mechanism underlying the onset and progression of osteoarthritis (OA) in the temporomandibular joint (TMJ). Understanding the mechanism of OA development in the TMJ helps in understanding how OA progresses and how to treat this disease. The goal of this investigation is to examine the process of cartilage degeneration and OA biomarker expression in the TMJ to understand their role in TMJ OA onset and development.Chapter one covers mechanisms that are altered in TMJ OA during disease progression. Using animal models with different stressors such as mechanical disturbances, direct injury, and changes in the extracellular matrix composition revealed the role of the different mechanisms that are up-regulated and down regulated during cartilage destruction. Chapter two will cover a paper I wrote that introduces a novel non-invasive technique applied to mice, which induces an early onset of OA in the TMJ. I developed this technique with the aim to provide a new mouse model where the onset and progression of OA more closely mimic the natural TMJ OA progression in humans. The histopathological analysis of the cartilage demonstrates that onset of OA starts at 2 weeks after treatment induction and is aggravated by week eight. This data demonstrated the effectiveness of our technique in inducing OA in the TMJ. Chapter three will cover a second paper I wrote on the association of RAGE with the progression of OA in the TMJ of mice by using mice with and without RAGE expression. RAGE has been show to contribute to the progression of OA by releasing several pro-inflammatory and catalytic cytokines. Additionally, RAGE has been shown to modulate the expression of specific OA biomarkers, including HtrA-1, Mmp-13, and Tgf-β1 in knee cartilage. The objective of this study was to study the effect of knocking out RAGE on the expression of Mmp-1 3, HtrA-1, and Tgf-β1 in the TMJ. After histophatological and quantitative analysis of biomarkers expression, the results demonstrated for the first time that absence of RAGE expression in the TMJ provides a protective effect against development of TMJ OA in mice.

Abstract:
Objetivo: Avaliar a função da coluna cervical, utilizando testes clínicos cervicais em indivíduos com e sem Disfunção Temporomandibular (DTM) associados ou não ao relato de dor de cabeça. Métodos: Estudo Transversal. Foram avaliadas 57 mulheres com idade de 18 a 60 anos, divididas em dois grupos: DTM (n=40), e controle (n=17). Dada a alta frequência de relato de dor de cabeça a amostra de DTM foi estratificada em DTM com cefaleia (n=25) e DTM sem cefaleia (n=15). A incapacidade cervical foi avaliada pelo Índice de Incapacidade Cervical (NDI) e a dor na ATM pela Escala Visual Analógica de dor (EVA). A avaliação funcional da coluna cervical foi conduzida uma única avaliação por um examinador fisioterapeuta experiente e foi constituída pelos testes clínicos: análise da Amplitude de Movimento Ativa da Coluna Cervical (ADM); realização do Flexion-Rotation Test (FRT) e Cranio-Cervical Flexion Test (CCFT). Os sujeitos com DTM que relataram a presença de dores de cabeça foram instruídos a responder um questionário sobre as principais características da cefaleia referida. Para comparações entre os grupos foram aplicados ANOVA one way seguida por teste Post Hoc de Tukey ou por Teste Kruskall Wallis quando necessário. Para a análise de associação entre as variáveis categóricas foram aplicados Teste chi-quadrado ou Teste Exato de Fisher quando apropriado e para a análise de associação entre variáveis ordinais/contínua foram aplicados Testes de Correlação de Spearman. Resultados: Os indivíduos com DTM independente do relato de dor de cabeça apresentaram menor mobilidade no plano sagital, menores valores no FRT e apresentaram pior performance dos flexores profundos cervicais comparados aos controles (p<0.05). Além disso, os dados de ADM, FRT e CCFT foram associados com a intensidade de dor na ATM e a incapacidade cervical (p<0.01). Conclusão: Pacientes com DTM independente do relato de cefaleia apresentaram limitação na amplitude de flexão/extensão e do segmento C1-C2 da coluna cervical, além do menor desempenho dos músculos flexores profundos. Adicionalmente, a incapacidade cervical e a dor na ATM apresentaram correlação moderada com os testes funcionais cervicais nos indivíduos com DTM.
Objective: To evaluate the function of the cervical spine, using cervical clinical tests in individuals with and without Temporomandibular Disorders (TMD)associated or not to the report of headache. Methods: Were analyzed 57 women with age between 18 and 60 years, divided in two groups: TMD (n=40) and control (n=17). Given the high frequency of headache report, the TMD sample was stratified into TMD with headache (n=25) and TMD without headache (n=15). Cervical disability was assessed by the Neck Disability Index (NDI) and TMJ pain by the Visual Analogue Scale of pain (VAS). The functional evaluation of the cervical spine was conducted by a physiotherapeutic examiner with 10 years of experience and was constituted by the clinical tests: Analysis of the Cervical Range of Motion (CROM); Flexion-Rotation Test (FRT) and Craniocervical Flexion Test (CCFT). Subjects with TMD who reported the presence of headaches were instructed to answer 11 questions that contained the main characteristics of referred headache. For comparisons between control groups, TMD with Headache and TMD without Headache, ANOVA was applied one way followed by Tukey\'s Post Hoc test or by Kruskall Wallis test when necessary. For the analysis of association between the categorical variables, chi-square test or Fisher\'s exact test were applied when appropriate and for analysis of association between ordinal / continuous variables, Spearman\'s Correlation Tests were applied. Results: Individuals with TMD independent of headache report showed less mobility in the sagittal plane, lower values in FRT and showed worse performance of the deep cervical flexors compared to Controls (p<0.05). In addition, CROM, FRT and CCFT were associated with an intensity of TMJ pain and cervical disability (p <0.01). Conclusion: Patients with TMD independently of the headache report showed limited flexion / extension range and C1-C2 segment of the cervical spine, as well as deficits in the performance of the deep flexor muscles. In addition, a cervical disability and TMJ pain report showed a moderate correlation with the functional tests of FRT and CCFT in individuals with TMD.

O uso de simuladores médicos é de grande importância para o estudo, diagnóstico e decisão sobre a melhor forma de tratamento de inúmeras patologias. Uma patologia que afeta inúmeras pessoas é o deslocamento ou displasia dos discos da articulação temporomandibular trazendo grandes transtornos no processo de abertura e fechamento da boca e fortes dores no momento da mastigação. O presente trabalho tem por objetivo modelar os deslocamentos mandibulares baseado em colisões entre os côndilos e as fossas temporais, bem como a interferência do disco articular com patologia na trajetória do movimento da mandíbula. O presente estudo utilizou dados reais de um paciente traduzidos por modelos tridimensionais de ossos reconstruídos a partir de imagens de tomografia computadorizada e de discos articulares reconstruídos a partir de imagens de ressonância magnética. O modelo de movimento da Articulação Tempormandibular é baseado no movimento mandibular de Posselt aliado ao tratamento de colisões entre as partes anatômicas em questão a partir de leis da física. Como resultado é apresentado comparações de trajetórias de movimento entre uma articulação saudável e uma articulação com patologia relacionada ao disco articular. No movimento realizado por uma ATM com anteposição de disco, a mandíbula é impedida de se deslocar corretamente, impossibilitando a abertura total da boca.
The use of medical simulators is of great importance for the study, diagnosis and decision about how best to treat numerous diseases. A condition that affects many people is the displacement or dysplasia of temporomandibular joint discs bringing major disruptions in the process of opening and closing the mouth and severe pain when chewing. This study aims to model the mandibular displacements based on collisions between the condyles and temporal fossa, and the disc with pathology interference on jaw motion trajectory. Real data as three-dimensional models of bones reconstructed from CT images and articular disc reconstructed from RM images was used as model parameters. The Tempormandibular joint motion model is based on Posselt’s mandibular movement joined to the processing of collisions between anatomical parts in question using physics laws. As a result is presented comparisons of motion trajectories between a healthy joint and a joint with pathology related to articular disk. In the motion carried by an ATM with disk fronting , the jaw is prevented from moving correctly, making it impossible to fully open the mouth.

Abstract The mandibular kinematics, which has been often represented by the condylar movement of the temporomandibular joint (TMJ), has played a crucial role in the foundation of the modern dentistry. Though the fact that the condyle could perform rotation and translation has been long recognized, the calculation of the amount of rotation hasn’t been solved till recently, after the introducing of rigid-body mechanics into this field. Since then, errors of the classical mandibular kinematics, which has been built based on the pantographic observations, were gradually disclosed. Unfortunately, an unbiased, clear, concrete conclusion of the normal mandibular kinematics is still lacking. To study the mandibular kinematics completely, i.e. including 3 translational and 3 rotational degree-of-freedoms (DOF), needs sophisticated hardware and high data manipulation ability. Now combining the opto-electronic tracing devices and the rigid-body mechanics to record and analyze the 6 DOF mandibular movements has been gradually become the main-stream methodology in dentistry. However, the standard operating procedure of placing the markers to represent the head and mandible position in space hasn’t been established, yet. Some data presenting ways of the mandibular kinematics hasn’t been validated, either. The aims of these serial studies were therefore first to optimize the use of an opto-electronic tracking device, Vicon 512, to study the human mandibular kinematics, and second to analyze the motion data by using calculations successfully applied to other major human joints. The results would be compared with other analyses ever proposed in dentistry. Instrument setup: Five mega-pixel Vicon IR cameras were used to pick up the positions of markers within the global coordinating system with the temporal resolution of 120 Hz. The camera placements were optimized configured after several trials so the following working environments can be yielded: Working volume: 50 cm x 50 cm x 50 cm Spatial resolution: 0.0008 mm Absolute system measuring error: < 0.4 mm Skin marker placements: In order to reduce the interfering of physiological movements by the trans-oral metal framework, the skin markers were used to represent the head position. After quantitative comparisons the following conclusions were obtained: 1. Skin areas near upper facial midline possessed least amount of skin movement. Their relative movements were even smaller than the optical frame by referencing to the gold standard, i.e. the clutch attached to the maxillay anteriors. 2. After the adjustment by applying the “Segmental Optimization Method” (S.OM.), the adverse effect of skin movement on these least mobile markers could be significantly reduced. 3. Skin markers could be used to represent the head positions while put on selective areas plus the S.O.M. adjustment. Their error was roughly equaled to the absolute system measuring error. Translation/Rotation Diagram: The translation/rotation diagram, which was proposed by Salaorni et al in 1994, is a concise description of condylar kinematics in 2D. However, the methodology itself hasn’t been validated. Namely, 1. The amount of condylar translation was reference-point dependent. Different condylar points would have different diagrams. 2. If we re-plotted the diagram by using the first order derivative of translation/ rotation vs. rotation, the kinematic behavior of the condyle would have dramatic different characters. The classification of 5 patterns proposed by Salaroni et al. was thus challenged. Helical axis: The mandibular helical axis was also calculated. The intersections of the helical axis on sagittal planes passing both side condyles were also presented. Contrast to the condylar trajectories, the orientations and paths of the helical axes changed dramatically and were hardly predictable. These findings were compatible with the helical axes of other major joints.

Abstract:
The mucopolysaccharidoses (MPS) are a group of seven chronic progressive diseases caused by deficiencies of 11 different lysosomal enzymes required for the catabolism of glycosaminoglycans (GAGs). Hurler syndrome (MPS IH) is an autosomal recessive storage disorder caused by a deficiency of α‎-L-iduronidase. Hunter syndrome (MPS II) is an X-linked recessive disorder of metabolism involving the enzyme iduronate-2-sulfatase. Many of the MPS clinical manifestations have potential anesthetic implications. Significant airway issues are particularly common due to thickening of the soft tissues, enlarged tongue, short immobile neck, and limited mobility of the cervical spine and temporomandibular joints. Spinal deformities, hepatosplenomegaly, airway granulomatous tissue, and recurrent lung infections may inhibit pulmonary function. Odontoid dysplasia and radiographic subluxation of C1 on C2 is common and may cause anterior dislocation of the atlas and spinal cord compression.

Abstract:
Chapter 110 provides a systematic approach to the imaging techniques and interpretation of the temporomandibular joint (TMJ). The most common TMJ conditions and treatment options are discussed. The TMJ plays a crucial role in mastication, jaw mobility, and verbal and emotional expression. Temporomandibular disorders (TMDs) include several entities that can lead to orofacial pain symptoms. Common symptoms include jaw pain, jaw dysfunction, earache, headache, and facial pain. Multiple risk factors have been implicated, including trauma, anatomical factors, pathophysiological factors, and psychosocial factors. TMJ dysfunction is best evaluated with MRI. Internal derangement is the most common TMJ disorder, followed by degenerative joint disease.
