    Full Text Available The most common cause of orofacial pain is the Temporomandibular Joint Disorder (TMD, a collective term used to describe a group of medical disorders causing temporomandibular joint (TMJ pain and dysfunction. As the causes of TMD are varied and run the gamut from mechanical issues, such as disc degeneration and dislocation or erosion of the fibrocartilaginous surfaces of the condyle, fossa, and articular eminence, the treatment approaches for the chronic TMJ case are also quite varied. As surgery is considered a last resort for TMD, it is common for sufferers to seek out alternatives and one of the alternative treatments is ′Prolotherapy,′ which is also known as Regenerative Injection Therapy. This article provides an overview of this new alternative therapy.

    Full Text Available Psychoneuroimmunology characterizes a disease entity that combines psychological components, central nervous system regulation, and immunology, to explain the etiological complexity of a disease. Temporomandibular disorders (TMDs include a heterogeneous group of painful conditions that involve the temporomandibular joint (TMJ, muscles of mastication, and the adjacent anatomic structures. This review focuses on the psychoneuroimmunological diseases and disorders that mimic the symptoms of TMDs. The differentiation of these disorders is of great significance to the oral physician - differentiating and diagnosing the cause of TMJ pain and treating it effectively to benefit the patient.The literature for this review was taken from Medline/PubMed, other indexed journals, standard text books, and online material.

    Temporomandibular (TM) joint pain results from many etiologic factors. The aim of this study was to evaluate the utility of Bone SPECT in patients with TM joint pain. The subjects were 34 patients with TM joint pain. All patients underwent plain radiography, planar bone scan, and Bone SPECT. The intensity of radioisotope uptake at TM joint was graded into three; no increased uptake above the background activity as grade 0, uptake similar to occipital bone as grade I, and uptake similar to maxillary sinus as grade II. Clinical findings and therapeutic methods were reviewed. Twenty-seven patients (80%) out of 34 patients with TM joint pain had increased uptake in bone SPECT. Twenty-one (78%) out of 27 patients had increased uptake in the mandibular condyle and remaining six patients (22%) had uptake in the mandibular and maxillary arch, which proved to be dental problem. Seven patients (21%) out of 34 were grade as 0, four (12%) were grade I, 23 (68%) were grade. II. Four patients with grade I had clicking sound and symptoms which were subsided with medication in all cases. Among 23 patients with grade II, 7 patients had clicking sound and 14 patients underwent medication and decompression therapy. With Planar bone scan, 11 cases (32%) had increased uptake in TM joint area. Plain radiography revealed narrowing, distension, erosion and limitation of TM joint in 16 cases (47%). Bone SPECT can be valuable for screening and managing the patients with TM joint pain. Patients with grade II needed intensive treatment such as joint aspiration. However degree of the radioisotope uptake did not well correlated with clinical symptoms

    Full Text Available Temporomandibular joint dysfunction is a functional disorder concerned with the abnormal functioning of the muscles of the stomatognathic system and temporomandibular joints involved in the dynamic movements of the jaw and surrounding structures. The aim of the study was to compare the level of C-reactive protein in patients with pain and painless forms of temporomandibular joint dysfunction. Materials and methods. The study group consisted of 72 patients who reported to the prosthetic treatment because of temporomandibular joint dysfunction. The study group included 36 patients with pain form of dysfunction, and the control group included 36 patients with painless form of disorder. Each patient underwent specialized examination of functional disorders in order to diagnose the type of dysfunction and was commissioned to carry out a study of the blood test concerned with evaluation of the C-reactive protein (CRP level in the same analytical laboratory. The results of the investigation were subjected to statistical analysis. The research obtained approval from the Ethics Committee of the Jagiellonian University (KBET/125/L/2013. Level of Evidence for primary research was established as type V. Results. The mean values of C-reactive protein levels in both groups were in the normal range and did not differ statistically significantly, which indicates the fact that the pain form of the temporomandibular joint disorders is not associated with inflammation of the soft tissues of the joint. Conclusion. Painful form of the temporomandibular joint dysfunctions is not connected with the inflammation of joints.

    This paper determines the frequency of MR signs of abnormal temporomandibular joints (TMJs) in asymptomatic volunteers. Forty-two volunteers with 84 clinically normal TMJs were imaged in the sagittal and coronal planes with surface coil MR imaging. Sagittal closed and open and coronal closed views were obtained bilaterally in all volunteers. The images were classified as normal (superior disk position) or abnormal (disk displacement of degenerative joint disease). Eighteen joints in 11 volunteers were abnormal; 12 had disk displacement with reduction and six had disk displacement without reduction, with associated degenerative joint disease in three of the six. Asymptomatic internal derangement and degenerative joint disease occur in about one-fourth of asymptomatic volunteers

    To compare prevalences of self-reported comorbid headache, neck, back, and joint pains in respondents with temporomandibular joint and muscle disorder (TMJMD)-type pain in the 2000-2005 US National Health Interview Survey (NHIS), and to analyze these self-reported pains by gender and age for Non-Hispanic (NH) Whites (Caucasians), Hispanics, and NH Blacks (African Americans). Data from the 2000-2005 NHIS included information on gender, age, race, ethnicity, education, different common types of pain (specifically TMJMD-type, severe headache/migraine, neck, and low back pains), changes in health status, and health care utilization. Estimates and test statistics (ie, Pearson correlations, regressions, and logistic models) were conducted using SAS survey analysis and SUDAAN software that take into account the complex sample design. A total of 189,977 people (52% female and 48% males, 73% NH Whites, 12% Hispanic, 11% NH Blacks, and 4% "Other") were included. A total of 4.6% reported TMJMD-type pain, and only 0.77% overall reported it without any comorbid headache/migraine, neck, or low back pains; also 59% of the TMJMD-type pain (n = 8,964) reported ⋝ two comorbid pains. Females reported more comorbid pain than males (odds ratio [OR] = 1.41, P neck pain, 64% low back pain, and 62% joint pain. Differences in gender and race by age patterns were detected. For females, headache/migraine pain with TMJMD-type pain peaked around age 40 and decreased thereafter regardless of race/ethnicity. Neck pain continued to increase up to about age 60, with a higher prevalence for Hispanic women at younger ages, and more pronounced in males, being the highest in the non-Whites. Low back pain was higher in Black and Hispanic females across the age span, and higher among non-White males after age 60. Joint pain demonstrated similar patterns by race/ethnicity, with higher rates for Black females, and increased with age regardless of gender. TMJMD-type pain was most often associated with

    Whilst the temporomandibular joint is in many ways unique, it is subject to all the diseases and disorders found in joints in other parts of the human skeleton. By far the most common disorder is injury, followed by arthropathy, acute and chronic dislocations, ankylosis, and in rare instances, neoplasms. The diagnosis and management of the temporomandibular joint are the primary responsibility of the oral surgeon. Nevertheless, this anatomical region is an area in which the cooperation of medical and dental disciplines may be required for the satisfactory conclusion of treatment. The more so when the disease process involves either associated psychosomatic illness or malignancy. The mainstay of the diagnosis is a careful radiological examination of the joint. There exists a delicate relationship between the dentition, the muscles of mastication, and the temporomandibular articulation, which is controlled by arthrokinetic reflex activity of the branches of the 5th cranial nerve. Imbalance between one or more of the components of this integrated system frequently leads to disturbances in function. Pain-dysfunction disorders constitute the larger part of temporomandibular joint disturbances generally encountered

    Temporomandibular joint syndrome, or Costen syndrome, is a clinically diagnosed disorder whose most common symptoms include joint pain and clicking, difficulty opening the mouth, and temporomandibular joint discomfort. The temporomandibular joint (TMJ) is supplied by the auriculotemporal nerve, a collateral branch of the mandibular nerve (the V3 branch of the trigeminal nerve). The aim of this study is to assess the effectiveness and safety of permanent peripheral nerve stimulation to relieve TMJ pain. This case series is a prospective study. Pain Unit of a regional universitary hospital. The study included 6 female patients with temporomandibular pain lasting from 2 to 8 years that did not respond to intraarticular local anesthetic and corticoid injections. After a positive diagnostic block test, the patients were implanted with quadripolar or octapolar leads in the affected preauricular region for a 2-week stimulation test phase, after which the leads were connected to a permanent implanted pulse generator. Results of the visual analog scale, SF-12 Health Survey, Brief Pain Inventory, and drug intake were recorded at baseline and at 4, 12, and 24 weeks after the permanent implant. Five out of 6 patients experienced pain relief exceeding 80% (average 72%) and received a permanent implant. The SF-12 Health Survey results were very positive for all specific questions, especially items concerning the physical component. Patients reported returning to normal physical activity and rest at night. Four patients discontinued their analgesic medication and 1 patient reduced their gabapentin dose by 50%. Sample size; impossibility of placebo control. Patients affected with TMJ syndrome who do not respond to conservative treatments may find a solution in peripheral nerve stimulation, a simple technique with a relatively low level of complications.

    Recent years have shown an increase in the number of patients reporting for treatment of pain due to musculoskeletal joint, associated with temporomandibular joint dysfunction. Therefore, studies were undertaken, aimed at analyzing the symptoms of the dysfunction, because of which patients come to the prosthetic treatment. Aim of the thesis: The aim of the study was a retrospective analysis of symptoms of temporomandibular joint dysfunction reported by patients diagnosed with this problem. The research material was a retrospective medical records of 120 patients, aged 19 to 45 years who have taken prosthetic treatment due to temporomandibular joint dysfunction in the Consulting Room in Prosthetics Department in Kraków, from June 2015 to December 2016. During the test patients, in addition to interviewing a physician, completed a personal survey in their own study. The material has been divided into I group of patients who reported pain form of dysfunction and II group, who had no symptoms of pain within the stomatognatic system. The analysis covered type of symptoms, the share of local factors (para-functions) and systemic, as well as the time a er which the patients reported for the treatment of functional disorders since the appearance of the first symptoms. Analysis of the research material showed that the main reason for reporting patients was pain in one or both temporal joints of significant intensity (5 to 8 in VAS scale,) accompanied by acoustic symptoms. A large group of questioners reported problems with the range of jaw movement and head and face pain, as well as subjective symptoms from the auditory, sight, neck, neck and shoulder areas.

    Purpose: We aimed to assess the contrast enhancement patterns of the retrodiscal tissue with dynamic contrast-enhanced MR imaging (DCE-MRI) with respect to different temporomandibular joint disc pathologies. Additionally, we questioned the relationship between the temporomandibular joint (TMJ) pain and the contrast enhancement pattern of the retrodiscal tissue regardless of the TMJ disc position. Materials and methods: 52 joints of 26 patients (4 males and 22 females) who have pain in at least at one of their TMJ were included in this study. For the qualitative analysis, the joints were divided into four groups in terms of their disc positions: normal (1), partially displaced with or without reduction (2), totally dislocated with reduction (3) and totally dislocated without reduction (4). Besides, two different joint groups were constituted, namely the painful group and painless group according to the clinical findings without taking the TMJ disc positions into account. Quantitative analyses were made by means of measuring signal intensity ratios (SI) ratio at the retrodiscal tissue (from internal side and external side of the each joint) using DCE-MRI and these measurements were analyzed with paired samples t test to define the difference between the measurements. At the second stage, the time-dependent arithmetical mean values of the SI ratios were calculated for each joint group and significant differences between the groups were questioned using analysis of variance (ANOVA) test. Besides, painful and painless groups which were classified on the basis of the clinical data were compared according to the mean SI ratios found for each joint and the significant differences between these two groups were assessed by means of Student's T test. The results were assessed in 95% confidence interval where the significance level was p < 0.05. Results: A significant difference was observed between the internal and external contrast enhancement of the joints with partial

    Full Text Available The temporo-mandibular joint (TMJ it’s a joint closely related to the skull base, the spine, and the jaws; all these anatomical structures must be taken in consideration when evaluating pain involving the tmj. In order to detect patients affected by pathology or dysfunctions of the tmj, physical examination is of great value in orienting the diagnosis. Inspection must consider the symmetry of the body, the dental status and the type of occlusion. Palpation is a way to assess contractiont involving the muscles of the masticatory system and of the neck. Auscultation, based on articular noise provides means to determine whether we are dealing with degeneration of the joint or a dislocation of the intrarticular disc. In order to confirm the diagnosis obtained with the clinical evaluation, it’s useful to perform imaging techniques as opt, tomography and TC of the tmj and electromyokineosiography – index of the mandibular functionality and of the muscles status. MRI and dynamic MRI are among the non invasive exams which give the greatest amount of information, regarding the disc position and the joint degeneration. Arthroscopy is an invasive technique that allows early diagnosis of degeneration and is helpful to reveal early inflammatory processes of the joint.

    Objective. To evaluate the efficiency of DVT in comparison with OPG in the assessment of bony condylar changes in patients of TMJ pain. Methods. 100 temporomandibular joints of 62 patients with the complaint of temporomandibular joint pain were included in the study. DVT and OPG radiographs were taken for all the 100 joints. Three observers interpreted the DVT and OPG radiograph for the bony changes separately for two times with an interval of one week. The bony changes seen in the condyle were given coding from 0 to 6. (0: Normal, 1: Erosion, 2: Flattening, 3: Osteophyte, 4: Sclerosis, 5: Resorption, and 6: other changes). Interobserver and intra observer variability was assessed with one-way Anoka statistics. Z test was used to see the significant difference between OPG and DVT. Results. In the present study the inter examiner reliability for Og and DVT was 0.903 and 0.978, respectively. Intra examiner reliability for OPG and DVT was 0.908 and 0.980, respectively. The most common condylar bony change seen in OPG and DVT was erosion followed by flattening and osteophyte. There was significant difference between OPG and DVT in detecting erosion and osteophytes. The other changes observed in our study were Elys cyst, pointed condyle, and bifid condyle. All the bony changes are more commonly seen in females than males. Conclusion. DVT provides more valid and accurate information on condylar bony changes. The DVT has an added advantage of lesser radiation exposure to the patient and cost effectiveness and could be easily accessible in a dental hospital

    The aim of this study was to investigate the prevalence and intensity of masticatory muscle and temporomandibular joint (TMJ) pain in Croatian war veterans with posttraumatic stress disorder (PTSD). The examined group consisted of 100 Croatian war veterans, in whom PTSD had previously been diagnosed. Patients were compared with 92 subjects who had not taken part in the war and in whom PTSD was excluded by psychiatric examination. The clinical examination consisted of palpation of the masticatory muscles, the prominent neck musculature, and TMJ. The examination technique used and the definition of items were previously tested for reliability and validity. 93% of the subjects with PTSD had masticatory muscle tenderness compared to 45.65% of the subjects in the control group (chi2 = 51.46, p < 0.0001). The most frequent painful location in the subjects with PTSD was the left lateral pterygoid site in 88%, and in subjects of the control group the right lateral pterygoid site in 28.26% of cases. The most painful location in the PTSD group was the left lateral pterygoid site in 72%, and in the control group the left posterior digastric in 4.35% of cases. 58% of the subjects with PTSD had TMJ tenderness compared to 3.26% of subjects in the control group (chi2 = 66.23, p < 0.0001). The most frequent painful location of TMJ in both groups was the left posterior capsule; in the PTSD group 38% and in subjects in the control group 2.17% of cases. The most painful location was the left posterior capsule in 28% of subjects with PTSD, while not one subject in the control group reported severe painful sensitivity. The very high frequency and intensity of pain in subjects with PTSD confirms the effect of stress on muscle and joint sensitivity, i.e. perception of pain.

    Full Text Available Existing therapies for symptoms related to painful clicking of the temporomandibular joint (TMJ have rarely met with complete success and predicting prognosis remains difficult. Few studies have reported the efficacy of maxillary flat occlusal splints (MFOSs for the treatment of painful clicking of the TMJ, and few studies have evaluated the predisposing factors that influence the clinical outcomes of MFOSs. The aim of this study was to investigate the treatment efficacy of MFOSs for painful clicking of the TMJ, and to determine the factors influencing TMJ therapy with MFOSs. We conducted a retrospective study of 109 patients suffering from unilateral clicking concurrent with preauricular area pain for at least 2 months between 2004 and 2008. Seventy-five patients were treated with an MFOS, while 34 patients did not receive MFOS therapy. Clicking score, pain-free maximal mouth opening, pain score, duration of the clicking sounds, age and bruxism were recorded during treatment and involved into the reviews. The degree of joint clicking was determined by a stethoscope placed in the anterolateral area of the external auditory canal and was divided into four grades. Data were analyzed using a Mann-Whitney U test, Fisher's exact test, and Student's t test. Results showed statistically significant differences in treatment outcomes between the MFOS-treated and control groups in clicking index, maximal mouth opening, pain and complete remission rates of symptoms within 1 year. Furthermore, for patients treated with MFOS, there were statistically significant differences in the clinical outcomes between those with a high clicking index and those with a low index before treatment. Factors significantly correlated with successful outcomes of MFOS included nocturnal bruxism, patient age and duration of clicking. MFOSs can be used to treat patients with painful clicking of the TMJ and related symptoms. The severity of clicking, bruxism, age and duration of

  3. The role of molecular pain biomarkers in temporomandibular joint internal derangement.

    2017-06-01

    There is evidence that low-grade inflammation may be responsible for pain and development of degenerative changes in temporomandibular joint internal derangement. This article reviews the current knowledge of the molecular mechanisms behind TMJ internal derangements. A non-systematic search was carried out in PubMed, Embase and the Cochrane library for studies regarding pathophysiological mechanisms behind internal derangements focusing on pain-mediating inflammatory and cartilage-degrading molecules. Recent data suggest that release of cytokines may be the key event for pain and cartilage destruction in TMJ internal derangements. Cytokines promote the release of matrix metalloproteinases (MMPs), and due to hypoxia, vascular endothelial growth factor (VEGF) is released. This activates chondrocytes to produce MMPs and reduce their tissue inhibitors (TIMPs) as well as the recruitment of osteoclasts, ultimately leading to cartilage and bone resorption. Also, proteoglycans have an important role in this process. Several cytokines, MMPs, TIMPs and VEGF have been identified in higher concentrations in the TMJ synovial fluid of patients with painful internal derangements and shown to be associated with the degree of degeneration. Other molecules that show elevated levels include hyaluronic acid synthase, disintegrin and metalloproteinase with thrombospondin motifs (ADAMTs), aggrecan, fibromodulin, biglycan and lumican. Taken together, more or less pronounced inflammation of TMJ structures with release of cytokines, MMPs and other molecular markers that interact in a complex manner may be responsible for tissue degeneration in internal derangements. As internal derangements may be symptom-free, the degree of inflammation, but also other mechanisms, may be important for pain development. © 2017 John Wiley & Sons Ltd.

    Headaches and facial pain are common in the general population. In many cases, facial pain can be resultant from temporomandibular joint disorders. Studies have identified an association between headaches and temporomandibular joint disorders suggesting the possibility of shared pathophysiologic mechanisms of these 2 maladies. The aim of this paper is to elucidate potential commonalities of these disorders and to provide a brief overview of an examination protocol that may benefit the headache clinician in daily practice. © 2012 American Headache Society.

  5. Temporomandibular Joint Regenerative Medicine

    Full Text Available The temporomandibular joint (TMJ is an articulation formed between the temporal bone and the mandibular condyle which is commonly affected. These affections are often so painful during fundamental oral activities that patients have lower quality of life. Limitations of therapeutics for severe TMJ diseases have led to increased interest in regenerative strategies combining stem cells, implantable scaffolds and well-targeting bioactive molecules. To succeed in functional and structural regeneration of TMJ is very challenging. Innovative strategies and biomaterials are absolutely crucial because TMJ can be considered as one of the most difficult tissues to regenerate due to its limited healing capacity, its unique histological and structural properties and the necessity for long-term prevention of its ossified or fibrous adhesions. The ideal approach for TMJ regeneration is a unique scaffold functionalized with an osteochondral molecular gradient containing a single stem cell population able to undergo osteogenic and chondrogenic differentiation such as BMSCs, ADSCs or DPSCs. The key for this complex regeneration is the functionalization with active molecules such as IGF-1, TGF-β1 or bFGF. This regeneration can be optimized by nano/micro-assisted functionalization and by spatiotemporal drug delivery systems orchestrating the 3D formation of TMJ tissues.

    This paper evaluates MR imaging with the therapeutic effect after splint therapy in internal derangement of the temporomandibular joint (TMJ). Fifteen patients (19 TMJs) with internal derangement of the TMJ and five normal volunteers (10 TMJs) were examined with sagittal T1-weighted spin-echo and gradient recalled acquisition in a steady state (GRASS) MR imaging. MR studies of the patients undergoing splint therapy were performed with an without splints. Pseudodynamic images of TMJ motion provide information that was not available from spin-echo T1-weighted images

    Full Text Available Disease phobia refers to a psychological state when the person continuously thinks that he/she is sick and improvement from the condition is impossible. Disease phobia in patients suffering from pain, secondary to temporomandibular disorders (TMDs, is usually the consequence of long-term problems; diagnosis and treatment of this group is a real challenge for healthcare professionals. Aim: The purpose of this prospective study was to objectively evaluate the role of Illness Attitude Scale (Kellner or IAS in measuring cancerophobia and heart disease phobia in patients suffering from pain, as a consequence of TMDs. Subjects and Methods: The cohort included 22 patients with TMDs who underwent evaluation of these phobias; pain was acute in 7 and chronic in 15. The patients were asked to complete the “Kellner” questionnaire, and this was followed by full clinical examination of the temporomandibular region. Results: When measuring the correlation between the cancerophobia and heart disease phobia patients, the outcome was found significant in the total cohort, p<0.01. Comparisons were carried out in the chronic group (n=15 and was significant (p=0.034 and r=0.549; while in the acute group no significance was identified. Conclusion: Cancerophobia and heart disease phobia in TMD patients are factors that need to be taken in consideration when managing chronic pain in this group.

    Lyme borreliosis is an endemic disease in Slovenia with an incidence of around 150 patients per 100,000 inhabitants. Although the large joints are most typically affected in Lyme borreliosis, there are also periods of disease activity with arthritis or arthralgias involving smaller joints, including the temporo-mandibular joint. During the years between 2000 and 2003, two patients with Lyme borreliosis affecting the temporo-mandibular joints were treated. The patients presented with fatigue and pain in diverse muscle groups accompanied by arthralgia, which was most pronounced in the temporomandibular joint area. None of the patients were febrile or had joint effusions. Both patients were examined by means of biochemical and serological examinations for Borrelia burgdorferi using ELISA assay and Western blot test (both for IgM and IgG), plain radiographs, MR and CT scans, and scinti-scan of the temporo-mandibular joints They both had positive serum markers for an acute B. burgdorferi infection and were treated with intravenous ceftriaxone. None of the patients had clinical or laboratory signs of chronic Lyme disease activity two and four years following therapy, respectively. Roentgenographic and nuclear magnetic resonance imaging of the temporo-mandibular joints had not shown any persistent sign of acute inflammation. There are only few reports of patients with manifest temporo-mandibular joint involvement of Lyme borreliosis in the literature. This report emphasizes the importance of differential diagnosis of acute temporo-mandibular joint arthralgia, of early diagnosis of Lyme borreliosis, and of the necessity for prompt antibiotic treatment.

    Temporomandibular joint dysfunction are often accompanied by symptoms of headache such as tension-type headache which is the most frequent spontaneous primary headache. Masseter muscle pain is commonly reported in this group. The purpose of the study was to assess the efficiency of intramuscular botulinum toxin type A injections for treating masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache. This prospective outcome study consisted of 42 subjects of both genders aged 19-48 years diagnosed with masseter muscle pain related to temporomandibular joint dysfunction and tension-type headache. The subjects were treated by the intramuscular injection of 21 U (mice units) of botulinum toxin type A (Botox, Allergan) in the area of the greatest cross-section surface of both masseter bellies. Pain intensity was evaluated using visual analogue scale (VAS) and verbal numerical rating scale (VNRS) 1 week before the treatment and 24 weeks after the treatment. The obtained data were analyzed using the Wilcoxon matched pairs test (p ≤ 0,005). The results of this study showed a decrease in the number of referred pain episodes including a decrease in pain in the temporal region bilaterally, a reduction of analgesic drugs intake as well as a decrease in reported values of VAS and VNRS after injections (p = 0,000). The intramuscular botulinum toxin type A injections have been an efficient method of treatment for masseter muscle pain in patients with temporomandibular joint dysfunction and tension-type headache.

    Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery. The goal is to increase function, reduce pain, and improve quality of life. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Summary:. Infection of the temporomandibular joint (TMJ is a rare pediatric condition resulting from the introduction of pathogens into the joint by hematogenous seeding, local extension, or trauma. Early recognition of the typical signs and symptoms including fever, trismus, preauricular swelling, and TMJ region tenderness are critical in order to initiate further evaluation and prevent feared complications of fibrosis, ankylosis, abnormal facial structure, or persistence of symptoms. Contrast-enhanced computed tomography with ancillary laboratory analysis including erythrocyte sedimentation rate, C-reactive protein, and white blood cell count are beneficial in confirming the suspected diagnosis and monitoring response to therapy. Initial intervention should include empiric parenteral antibiotics, early mandibular mobilization, and joint decompression to provide synovial fluid for analysis including cultures. This report describes a case of TMJ bacterial arthritis in a healthy 6-year-old male who was promptly treated nonsurgically with intravenous antibiotics and localized needle joint decompression with return to normal function after completion of oral antibiotics and physical therapy.

    Ten temporomandibular joints (TMJs) of 5 healthy volunteers and 19 TMJs of internal derangements in 16 patients with splint therapy were examined with MR imaging. T1-weighted images were obtained only in the closed mouth position, and gradient recalled acquisition in steady state (GRASS) images were obtained in active opening and closing phases, allowing a pseudodynamic display of TMJ movement. All patients received protrusive splint treatment. The usefulness of MR imaging to assess the efficacy of splint therapy was evaluated. Corrected disk position with the splint in place was clearly demonstrated in 9 TMJs, corresponding with elimination of reciprocal clicking. Ten other TMJs of anterior disk displacement without reduction showed uncorrected disk position by the splint. This information could confirm the therapeutic efficacy, or suggest other treatment alternatives. GRASS MR imaging can provide accurate and physiologic information about disk function in initial and follow-up assessment of protrusive splint therapy. (orig.)

    The presence and content of calcitonin gene-related peptide (CGRP) is evaluated in the hyperplastic retrodiscal tissue of the temporomandibular joint in patients with joint degenerative disease by radioimmunoassay. Study population has included 8 female patients in pre-menopausic status, without to be pregnant, without to be lactating for a year and with diagnostic of joint degenerative disease (osteoarthrosis). Pain levels are registered with visual analog scale, where 0 is absence of pain and 16 acute pain. A bone degeneration is classified as mild, moderate and severe, according to findings of nuclear magnetic resonance. The 15 retrodiscal hyperplastic tissue samples are taken from patients undergoing to open surgery of temporomandibular joint. The specimens were placed in plastic blocks with freezing medium and are stored at -70 degrees celsius until neuropeptide extraction by radioimmunoassay with kit for CGRP. A directly proportional relationship is established between the degree of bone degeneration and neuropeptide expression and between the osteoarthrosis classification with analogue visual scale. Findings have shown definitive correlation between pain levels and expression of neuropeptide. CGRP is expressed in the retrodiscal tissue of temporomandibular joint in human with joint degenerative disease and is directly related with levels osteoarthrosis and pain [es

    The objective of this study was to investigate whether a relationship exists between total antioxidant capacity (TAC) and total oxidant status (TOS) of synovial fluids (SFs) of temporomandibular joint (TMJ) pain patients with pain and dysfunction. Forty-two patients with TMJ pain were included in this study. TAC and TOS values of SFs were measured with a novel colorimetric method. Independent t test and correlations were used to analyze the data. TAC of SFs in patients with TMJ pain and limited mouth opening (LMO; n = 21) were significantly lower (P = 0.03) than patients without LMO (n = 21). TOS of SF was negatively correlated with duration of the disease. There was no correlation between TAC, TOS, and VAS scores of the patients as well as age and maximum mouth opening values. Antioxidant response to oxidative changes (TAC and TOS) in SF decreased as the stage of dysfunction increased. Local administration of antioxidant agents might be considered in management of TMJ pain and dysfunction to prevent possible increased oxidative stress.

    Changing lifestyles, decreasing physical activity, which is increasing the number of degenerative joint diseases of various etiology, and certain dental procedures are increasing the number of patients complaining of pain in their temporomandibular joints. The aim of the study was to assess the benefits of comprehensive physiotherapy sessions in order to decrease the number of temporomandibular joint problems, thereby improving the patient's quality of life. An examination by a dentist determined each patient's treatment plan, which consisted of a medical exam, physical therapy and education. Each form of treatment was applied 10 times at intervals of 7-14 days. The main goal of the therapeutic physical education was to redress the muscle imbalance in the mandibular joint. This was achieved by restoring balance between the masticatory muscles, along with releasing the spastic shrouds found in the masticatory muscles. The aim of education was to teach the patient exercises focused on the temporomandibular joint and masticatory muscles. The intensity of the exercises and their composition were individually adjusted and adapted to their current state. Physical therapy consisted of the application of pulsed magnetic therapy, laser therapy, and non-invasive positive thermotherapy. The above procedure was conducted on a therapeutic group of 24 patients (3 men and 20 women). In the course of therapy, there were no complications, and all patients adhered to the prescribed regime. None reported any side effects. The mean treatment duration was 123 +/- 66 days. The outcome of the therapy was evaluated as described in the methodology, the degree of pain affecting the joint, and the opening ability of the mouth. In both parameters, there was a significant decline in patient pain. In a study devoted to tactics of rehabilitation treatment for temporomandibular joint disorders, the need for comprehensive long-term therapy, involving education, and learning proper chewing habits

    Temporomandibular joint (TMJ) inflammation in patients with juvenile idiopathic arthritis (JIA) may lead to mandibular growth disturbances and interfere with optimal joint and muscle function. Orofacial symptoms are common clinical findings in relation to TMJ arthritis in adolescence. Knowledge about their clinical manifestation is important for TMJ arthritis diagnosis, treatment choice, and outcome evaluation. The aim of our prospective observational study was to evaluate and describe the frequency, the main complaints, and the localization of TMJ arthritis-related orofacial symptoms. The smallest detectable differences (SDD) for minimal, average, and maximal pain were estimated. Thirty-three patients with JIA and arthritis-related orofacial symptoms in relation to 55 affected TMJ were included in our questionnaire study (mean age 14.11 yrs). Calculation of the SDD was based on a duplicate assessment 45 min after the first questionnaire was completed. The majority of the patients had common orofacial symptoms during mastication and maximal mouth opening procedures. Persistent orofacial symptoms were rare. The TMJ area in combination with the masseter muscle region was the orofacial region where symptoms were most common. The SDD for minimal, average, and maximal pain were between 10 and 14 mm on a visual analog scale. Our study offers new knowledge about TMJ arthritis-related orofacial symptoms that may aid diagnosis and clinical decision-making. We suggest that TMJ arthritis-related orofacial symptoms could be understood as products of the primary TMJ inflammation in combination with secondary myogenic and functional issues.

    The author presents an attempt of using ultrasonographic technique in diagnosis, planning and observation of treatment results of temporo-mandibular joint pain dysfunctions. Temporo-mandibular joint pain dysfunctions are interchangeably also called temporo-mandibular joint functional disorders. The assessment of pain symptoms in temporo-mandibular joint dysfunctions pain symptoms is principally based on a subjective estimation by the examining practitioner. There is no univocal definition of the disease or a simple index evidencing important symptoms in decision making. Additionally X-ray technique examinations, being hitherto used, in early stages of the disorder do not allow to diagnose it, and are also burdensome to a patient. The aim of this study was to confirm visibility of anatomical elements of the temporo-mandibular joint in an ultrasound examination, assess the mobility of the articular disc before, during and after prosthetic treatment with and without the use of ultrasound technique, and to determine the period of time necessary to obtain a therapeutic effect. The study material consisted of 180 patients, 128 women and 52 men, aged 20 to 60 years, treated by applying prostheses because of temporo-mandibular joint pain dysfunction, in the Department of Prosthetic Dentistry of the Pomeranian Medical Academy. The patients were divided into 2 groups, control and study group. The control group consisted of 90 patients, 63 women and 27 men. In this group prosthetic treatment planning and observation of results was based on a subjective estimation of the practitioner. The study group here comprised 90 patients, 65 women and 25 men, aged 26 to 60 years. In this group prosthetic treatment planning and observation of treatment results were carried on with the use of ultrasound technique. Data from both groups concerning history, results of examinations carried out by ultrasound technique, and the assessment of ultrasound examination were noted on standard

    Full Text Available Objective: to investigate the efficiency of an integrated approach to treating craniomandibular dysfunction, by changing the biomechanical tempomandibular joint (TMJ movement pattern via botulinum toxin type A injection into the masticatory muscles.Patients and methods. The investigation enrolled 20 patients aged 18-45 years with clinical signs of muscular-articular dysfunction of the TMJ. Before and after treatment, all the patients underwent magnetic resonance imaging of the TMJ and masticatory muscles, as well as ultrasonography and surface electromyography (EMG of the masticatory muscles.Results. There was a significant reduction in pain syndrome, an improvement in the relationship of intra-articular TMJ elements, and a change in the structure of the masticatory muscles. The EMG indices were near-normal. Four-six months after treatment, the majority of patients showed an increase in the amplitude of mouth opening (95%, reductions in resting pain (85% and in the frequency of TMJ clicking (90%.Conclusion. The management of patients with severe chronic pain syndrome in the presence of muscular-articular dysfunction of the TMJ requires the participation of an orthodontist to correct malocclusion and a neurologist to treat local myofascial pain syndrome.

    The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

    Full Text Available Rheumatoid arthritis (RA is a chronic, systemic, autoimmune inflammatory disorder that is characterized by joint inflammation, erosive properties and symmetric multiple joint involvement. Temporomandibular joint (TMJ is very rare to be affected in the early phase of the disease, thus posing diagnostic challenges for the dentist. Conventional radiographs fail to show the early lesions due to its limitations. More recently cone-beam computed tomography (CBCT has been found to diagnose the early degenerative changes of TMJ and hence aid in the diagnosis of the lesions more accurately. Our case highlights the involvement of TMJ in RA and the role of advanced imaging (CBCT in diagnosing the bony changes in the early phase of the disease.

    Objective A survey was held to establish whether laypeople knew the location of their temporomandibular joint. Methods A sample of 61 participants, visiting their dental office for a routine check-up, was given a three-question survey of whether they knew the location of their temporomandibular joint and could point to this location. Results Thirty-eight participants answered the question affirmatively. Only 13 pointed to the correct location. Of these, six participants received consultation for TMD in the past, three participants were healthcare providers, and four participants actually had knowledge of the exact location. Out of 23 participants who did not know the location, one accidently designated the correct position. Conclusion The location of the temporomandibular joint is not a well-known site for many patients. In the presence of orofacial pain, it seems advisable to let the patient designate and record the site of the pain on a drawing on the patient chart.

    Injuries of the temporomandibular joint are mostly due to injuries or fractures of the mandibular condyle. Fractures of the skull base involving the temporomandibular joint are rare. Classification of fractures refers to their anatomical positions and the presence or absence of a luxation. Further, it is important whether the fracture is intra- or extra-capsular. The primary imaging method should be orthopantomography. As for therapy planning, especially surgery, also evaluation of soft tissue is necessary, computed tomography is the imaging method of choice. For diagnosis of complications or internal derangement of the temporomandibular joint, magnetic resonance imaging is to be recommended. (orig.) [de

    Temporomandibular joint and dental occlusion are joined for better and worse. TMJ has its own weaknesses, sometimes indicated by bad functional habits and occlusal disorders. Occlusal analysis needs to be addressed simply and clearly. The term "malocclusion" is not reliable to build epidemiological studies, etiologic mechanisms or therapeutic advice on this "diagnosis". Understanding the impact of pathogenic malocclusion is not just about occlusal relationships that are more or less defective, it requires to locate them within the skeletal framework, the articular and behavioural context of the patient, and above all to assess their impact on the functions of the masticatory system. The TMJ-occlusion couple is often symbiotic, developing together in relation to its environment, compensating for its own shortcomings. However, a third partner may alter this relationship, such as bruxism, or more generally oral parafunctions, trauma or an interventionist practitioner. Copyright © 2016 Elsevier Masson SAS.

    Xue-Dong Wang

    Full Text Available BACKGROUND: Osteoarthritis (OA is an important subtype of temporomandibular disorders. A simple and reproducible animal model that mimics the histopathologic changes, both in the cartilage and subchondral bone, and clinical symptoms of temporomandibular joint osteoarthritis (TMJOA would help in our understanding of its process and underlying mechanism. OBJECTIVE: To explore whether injection of monosodium iodoacetate (MIA into the upper compartment of rat TMJ could induce OA-like lesions. METHODS: Female rats were injected with varied doses of MIA into the upper compartment and observed for up to 12 weeks. Histologic, radiographic, behavioral, and molecular changes in the TMJ were evaluated by light and electron microscopy, MicroCT scanning, head withdrawal threshold test, real-time PCR, immunohistochemistry, and TUNEL assay. RESULTS: The intermediate zone of the disc loosened by 1 day post-MIA injection and thinned thereafter. Injection of an MIA dose of 0.5 mg or higher induced typical OA-like lesions in the TMJ within 4 weeks. Condylar destruction presented in a time-dependent manner, including chondrocyte apoptosis in the early stages, subsequent cartilage matrix disorganization and subchondral bone erosion, fibrosis, subchondral bone sclerosis, and osteophyte formation in the late stages. Nociceptive responses increased in the early stages, corresponding to severe synovitis. Furthermore, chondrocyte apoptosis and an imbalance between anabolism and catabolism of cartilage and subchondral bone might account for the condylar destruction. CONCLUSIONS: Multi-level data demonstrated a reliable and convenient rat model of TMJOA could be induced by MIA injection into the upper compartment. The model might facilitate TMJOA related researches.

    To test in vitro and in vivo the reliability and accuracy of a new algometer, the pressure algometer for palpation (PAP), for measuring pressure pain thresholds (PPTs) and to compare its features with those of a commercially available pressure algometer. For in vitro accuracy testing, 6 repeated measurements were made at 8 defined test weights from 0.5 to 5 lb. In vivo validity testing compared the PAP to a standard instrument, the hand-held Somedic algometer, at 16 sites including the masticatory muscles, the temporomandibular joints, and the frontalis (as the control site) in 15 temporomandibular disorder (TMD) cases and 15 controls. Intraexaminer reliability was also assessed for both algometers. In vitro reliability was high, with coefficients of variation of test weights at r = .99 (P algometer. PPT values correlated moderately between the 2 devices (r ranged from 0.38 to 0.66; P algometers (P algometer showed high reliability. Concurrent validity was demonstrated by statistically significant correlations between the devices. Both showed equally high capacity for differentiating TMD cases from controls. The PAP yielded significantly higher PPTs than the Somedic algometer.

    The presence and content of calcitonin gene-related peptide (CGRP) is evaluated in the hyperplastic retrodiscal tissue of the temporomandibular joint in patients with joint degenerative disease by radioimmunoassay. Study population has included 8 female patients in pre-menopausic status, without to be pregnant, without to be lactating for a year and with diagnostic of joint degenerative disease (osteoarthrosis). Pain levels are registered with visual analog scale, where 0 is absence of pain and 16 acute pain. A bone degeneration is classified as mild, moderate and severe, according to findings of nuclear magnetic resonance. The 15 retrodiscal hyperplastic tissue samples are taken from patients undergoing to open surgery of temporomandibular joint. The specimens were placed in plastic blocks with freezing medium and are stored at -70 degrees celsius until neuropeptide extraction by radioimmunoassay with kit for CGRP. A directly proportional relationship is established between the degree of bone degeneration and neuropeptide expression and between the osteoarthrosis classification with analogue visual scale. Findings have shown definitive correlation between pain levels and expression of neuropeptide. CGRP is expressed in the retrodiscal tissue of temporomandibular joint in human with joint degenerative disease and is directly related with levels osteoarthrosis and pain [Spanish] La presencia y el contenido del peptido relacionado con el gen de la calcitonina (CGRP) es evaluado en el tejido retrodiscal hiperplasico de la articulacion temporomandibular en pacientes con enfermedad degenerativa articular mediante radioinmunoensayo.

    Temporomandibular disorders (TMD) refer to a group of clinical picture affecting the masticatory muscles and temporomandibular joint that are characterized by muscular or joint pain, dysfunction (limited or altered functions) and joint noises, as well as other associated symptoms, such as tension headaches, otalgia, dizziness, tinnitus, and others. Fibromyalgia (FM) is a syndrome of unknown etiology involving generalized chronic pain accompanied, in a high percentage of cases, by other symptoms such as asthenia, anxiety, depression, sleep disturbances, and other less frequent symptoms, such as temporomandibular disorders (TMD). Data were compiled by two experienced examiners following a specific form. An electronic search was carried out in the Cochrane Central Register of Controlled Trials (CENTRAL), PUBMED, and SCOPUS electronic databases (up to April 2016, unrestricted by date or language). Comparative clinical studies with patients with both clinical pictures involving the study of pathogenic processes. Fibromyalgia and temporomandibular disorders with muscle pain both have profiles that affect the muscular system and therefore share many epidemiological, clinical, and physiopathological symptoms. Because of this, we are led to think that there is, if not a common etiology, at least a common pathogenesis. This article revises the physiopathological processes of both clinical pictures in an attempt to determine their similarities and likenesses. This would undoubtedly help in providing a better therapeutic approach.

    The purpose of this study was to examine differences in heat pain threshold (HPTh) and heat pain tolerance (HPTo) between temporomandibular joint disorder (TMJD) patients and healthy controls. Using suprathreshold heat pain, this study also examined between-group (i.e. TMJD vs. healthy controls) differences in hyperalgesia and temporal summation (TS) of heat pain. Lastly, whether between-group differences in these heat pain outcomes were mediated by self-reported sleep quality was also tested. A total of 119 participants (41% TMJD) completed the current study. HPTh and HPTo responses were assessed at the ventral forearm with an ascending method of limits, while hyperalgesia and TS responses were assessed at the dorsal forearm at temperatures of 46, 48 and 50 °C. Prior to completion of heat pain procedures, participants completed the Pittsburgh Sleep Quality Index. Significant between-group differences in HPTh and HPTo were not observed. TMJD patients demonstrated significantly greater hyperalgesia than healthy controls at 46 °C only, but there were no differences for TS. Furthermore, TMJD patients reported significantly poorer sleep quality compared with healthy controls. Data analysis revealed a significant simple mediation effect whereby the presence of TMJD was strongly associated with poorer self-reported sleep quality, which, in turn, was related to enhanced hyperalgesia at 46 °C. These findings support the hypothesis that the thermal hyperalgesia demonstrated by TMJD patients may be related to poor quality of their self-reported sleep. The ability of interventions that improve sleep quality to also affect pain sensitivity is currently the topic of ongoing investigation. PMID:22344627

    To assess the feasibility and clinical outcomes of artificial condylar process in reconstruction of the temporomandibular joint. Between January 2005 and January 2010, the reconstructions of the temporomandibular joints with artificial condylar process were performed in 10 cases (11 sides, including 7 left sides and 4 right sides). There were 7 males and 3 females with an average age of 50 years (range, 40-68 years). Mandibular condyle defects were caused by mandible tumor in 7 patients with a mean disease duration of 15 months (range, 9-24 months) and by bilateral condylar fractures in 3 patients with the disease duration of 2, 3, and 2 days respectively. According to Neff classification, there were type M and A in 1 case, type M and B in 1 case, and type M in one side and subcondylar fracture in the other side in 1 case. Incisions in all patients healed by first intention, and no complication occurred. All cases were followed up 1 to 4 years, showed facial symmetry and good occluding relation, and the mouth opening was 22-38 mm (mean, 30 mm). No temporomandibular joint clicking or pain and no recurrence of tumor were observed. Most of the artificial condylar process were in good position except 1 deviated from the correct angle slightly. All the patients could have diet normally. The results of temporomandibular joint reconstruction after tumor resection with artificial condylar process are good, but the clinical outcome for intracapsular condylar fracture is expected to be further verified.

    The diagnostic value of conventional oblique-lateral transcranial standard projections for radiography of the temporomandibular joints is limited by various anatomical factors and the projection geometry. Improved results are obtained by individualization of the projection. The author describes a method for determining the individually optimum oblique-lateral projection, a method which is based on pre-exposure fluoroscopy of the temporomandibular joint with an electronic image intensifier system incorporating a television chain. The method has been employed as routine practice for 15 years; it has been modified several times and enables documentation studies to be made with an unusually high degree of reproducibility with respect to beam projection.

    The author analysed the routine radiographic changes and clinical symptoms of 205 cases of temporomandibular joint arthrosis. The clinical symptoms of the patients were classified and the morphological changes of condylar head, articular eminence, and articular fossa were analyzed and discussed from radiographic view point. The positional change of condylar head and articular fossa relation in TMJ arthrosis were observed. The frequencies of coincidence between the site of complaints and the site of the abnormal images which could be detected were examined. The results were obtained as follows; 1. Bone erosion, deformity, marginal proliferation and sclerosis were selected from many abnormal images as the radiographic diagnostic criteria of TMJ arthritic lesions. 2. Abnormal radiographic findings were revealed in 150 cases (73.9%) of 205 total TMJ arthrosis cases and site with abnormal findings coincided with the site of complaints in 105 cases (70.7%) of 150 cases and coincidence rates were higher above fourth decades than below third decades. 3. Sclerosis of the abnormal radiographic findings could be found more often below third decades than above fourth decades. 4. The positional changes of condylar head were revealed in 176 cases (85.9%) of 205 total cases. 5. Pain complaints were revealed in 170 cases(82.9%) and clicking sounds were revealed in 120 cases (58.6%) of clinical symptoms of TMJ arthrosis. 6. No tendency was found so far the differential diagnosis between pain dysfunction syndrome and osteoarthrosis of TMJ.

    Synovial Chondromatosis (SC) is a disease whose etiology is unknown, can be defined as a benign synovial process characterized by the formation of metaplastic cartilaginous nodes inside connective tissue of articular surfaces, is considered an active metaplastic phenomenon better than a neoplastic process; it presents a greater preference to affect women who constitute almost 70% of reported cases, the age range is wide and oscillates between 18-75 years (average 44.6 years). Between the main clinical findings are: pain, crackle, volume augmentation and a limited buccal opening. SC is an unusual state and the reports in the English literature are no more than 75 cases, only 66 of those where histologically verified, most of those were affecting great joints like hip, knee and shoulder, but if SC is not frequent in this sites, is even more infrequent on temporomandibular joint. The aim of this paper is to report a clinical case and at the same time to realize a brief review of the literature.

    Ankylosis of joint is defined as limited movement due to infection, trauma, or surgical procedure. A 59-year-old female with a chief complaint of limited movements during mouth opening had a positive history of trauma to her right TMJ area about 5 years ago. From that time, progressive mouth opening limitation and intermittent pain have occurred. At the time of admission the patient showed mandibular deviation to the right side during mouth opening, with a maximum opening limited to 5 mm. On plain radiographs, right condylar enlargement and joint space reduction by newly formed bony tissues were observed. CT scans showed right condylar enlargement, cortical sclerosis, and thickening of the condyle, articular fossa and articular eminence.

    Full Text Available ABSTRACT Temporomandibular joint dysfunction is a set of disorders involving the masticatory muscles, temporomandibular joint and associated structures. It is known that the progression of motor symptoms in Parkinson's disease is an indication that these people are more prone to the development of this dysfunction. Thus, this study aims to investigate the signs and symptoms of temporomandibular dysfunction in people with Parkinson's disease. The search was performed in the databases: MEDLINE/ PubMed, LILACs, CINAHL, SCOPUS, Web of Science and PEDro, without timing or language restriction. Specific descriptors were used for each database and keywords, evaluated by the instruments: Critical Appraisal Skill Program and Agency for Health care and Research and Quality. A total of 4,209 articles were found but only 5 were included. After critical analysis of the methodology of the articles, one did not reach the minimum score required by the evaluation instruments, thus, it was excluded. The selected articles addressed, as signs and symptoms of temporomandibular joint dysfunction, the following: myofascial pain, bruxism, limitation of mouth opening, dislocation of the articular disc and asymmetry in the distribution of occlusal contacts. Further studies are needed in order to determine the relationship between cause and effect of the analyzed variables, so as to contribute to more specific and effective therapeutic interventions.

    Attributing dysfunction of the temporomandibular joint (TMJ) to whiplash injury is a difficult problem to solve. TMJ disorders do not seem to be secondary to direct articular trauma but rather caused by a postural disorder of the cervical spine. Occlusal disorders and stress further complicate the picture. Four clinical cases illustrate a new hypothetical approach.

    Temporomandibular joint pain dysfunction syndrome (TMJPDS) is the most common temporomandibular disorder. This condition presents with symptoms of pain, restricted jaw movement and joint noise. Other symptoms include otalgia, headache, neck pain and trismus. To determine the pattern of Temporomandibular joint pain dysfunction syndrome patients managed at the Lagos University Teaching Hospital, Lagos, Nigeria. A descriptive study of patients with signs and symptoms of Temporomandibular joint pain dysfunction syndrome attending the Oral Medicine Clinic of Lagos University Teaching Hospital. Twenty-one patients with Temporomandibular joint pain dysfunction syndrome were enrolled into the study, out of which 10(48%) were females and 11(52%) were males. The age range was 23-81years with a mean of 45.2 ± 18.9 years. Majority of the patients 20(95.2%) complained of pain around the joint, in the pre-auricular region, in the muscles of mastication and the ear. While 7(35%) complained of clicking sounds, 10(47.6%) complained of pain on mouth opening and during mastication only. In all 5(23.8%) had impaired movement of the jaws, mouth opening was normal in 18(85.7%) but reduced in 3(14.3%) patients. Over half of patients 12(57%) experienced clicking sounds, there was tenderness around the temporomandibular joint in 16(76.2%) cases, pain in the ear of 7(33.3%) patients and 13(61.9%) people presented with tenderness of the muscles of mastication. Conservative management of all the cases resulted in resolution of the symptoms. Temporomandibular joint pain dysfunction syndrome has diverse clinical presentation and though distressing, it responds to prompt and effective conservative management.

    Nine patients with facial pain were evaluated with limited bone scans. The scintigrams correlated with microscopy in all patients, although radiographs correlated with microscopy in only five patients. The degenerative disease process in the temporomandibular joint was more extensive in the patients with radiographic and scintigraphic abnormalities than in those with scintigraphic abnormalities alone. The limited bone scan appears useful in detecting early degenerative changes in the temporomandibular joint

    Imaging of the temporomandibular joint(TMJ) is continuously evolving with advancement of imaging technologies. Many different imaging modalities are currently used to evaluate the TMJ. Magnetic resonance imaging is commonly used for evaluation of the TMJ due to its superior contrast resolution and its ability to acquire dynamic imaging for demonstration of the functionality of the joint. Computed tomography and ultrasound imaging have specific indication in imaging of the TMJ. This article focuses on state of the art imaging of the temporomandibular joint. Relevant normal anatomy and biomechanics of movement of the TMJ are discussed for better understanding of many TMJ pathologies. Imaging of internal derangements is discussed in detail. Different arthropathies and commontumors are also discussed in this article.

    Bilateral assessment of the temporomandibular joint space in children without joint disease is reported. Twenty-eight children were examined with conventional radiography and 23 with tomography. High prevalence of asymmetric joint spaces with both techniques indicated that great care should be taken when using narrowing or widening of the joint space as a diagnostic criterion in children with juvenile rheumatoid arthritis. Other signs, such as restricted translation of the mandibular head, and clinical symptoms should be evaluated. (Auth.)

    We report an unusual and rare cause of preauricular swelling and review the most recent literature concerning synovial osteochondromatosis of the temporomandibular joint. We report the clinical and radiologic findings of a case of synovial osteochondromatosis of the temporomandibular joint that presented as preauricular swelling in a female patient. This disease typically affects large joints; fewer than 100 cases reported in the literature affect the temporomandibular joint. This case illustrates that disorders of the temporomandibular joint should also be included in the differential diagnosis of patients who present with a preauricular mass.

    1996-01-01

    The principles of interventional video tomography were applied for the real-time visualization of temporomandibular joint movements in an augmented reality environment. Anatomic structures were extracted in three dimensions from planar cephalometric radiographic images. The live-image fusion of these graphic anatomic structures with real-time position data of the mandible and the articular fossa was performed with a see-through, head-mounted display and an electromagnetic tracking system. The dynamic fusion of radiographic images of the temporomandibular joint to anatomic temporomandibular joint structures in motion created a new modality for temporomandibular joint motion analysis. The advantages of the method are its ability to accurately examine the motion of the temporomandibular joint in three dimensions without restraining the subject and its ability to simultaneously determine the relationship of the bony temporomandibular joint and supporting structures (ie, occlusion, muscle function, etc) during movement before and after treatment.

    1990-01-01

    Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups (p<0.05) 5. The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, fourteen (36.9%) were

    1998-01-01

    The purpose of this study was to prove the relationship between arthrographic and clinical features in temporomandibular joint disorders. In order to carry out this study, ninety-eight arthrographic examinations of temporomandibular joints were performed in eighty-two patients who had the temporomandibular joint disorders. As the arthrographic examination, the cases were classified in three groups, disk displacement with reduction, disk displacement without reduction, within normal limit. After this, the cases were clinically examined, and the results were compared and analyzed in each other group. The obtained results were as follows ; 1. As the classification by arthrographic examination, three groups (disc displacement with reduction, disc displacement without reduction, within normal limit) were 41%, 54%, 5% of total cases in this study, respectively. 2. The third decade (65%) was most frequent in this study. The average age of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 24, 28, 21, and disc displacement without reduction group was higher than any other group. 3. In the chief complaint, pain was the most frequent in all three groups. Joint sound was also frequent in disc displacement with reduction group, but in disc displacement without reduction group, limitation of mouth opening was more frequent. 4. Of the various pain, the movement pain was most frequent (61%) in this study. In joint sound, click (63%) was the most frequent in disc displacement with reduction group, but sound history (42%) and no sound (31%) were more frequent in disc displacement without reduction group. 5. The average maximum opening of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 44 mm, 32.9 mm, 44 mm, and disc displacement without reduction group was less than any other group. 6.

    Full Text Available Temporomandibular joint (TMJ forms an integral functional part of stomatognathic system. Position, shape, structure and function of teeth have an influence on the proper functioning and health of TMJ. But a problem associated with TMJ is often neglected, and treatment for it is mostly restricted to palliative therapy. A proper understanding of the underlying cause of temporomandibular joint disorder (TMD is necessary to device a proper treatment plan. Etiology of TMDs varies from idiopathic reasons to systemic disorders. The option of Gnathological splint is a conservative, safe and an effective mode of therapy for TMDs caused by occlusal discrepancies (fulcrum/interferences. This article presents a case report of a patient with TMD caused by occlusal discrepancy

    Tinnitus has been described in temporomandibular joint dysfunction for a long time. Yet, other disorders, such as hearing loss, stress, anxiety and depression, play a major role in the pathophysiology of tinnitus. Temporomandibular joint dysfunctions seem to increase the risk of tinnitus in patients with other predisposing factors. Especially somatosensory tinnitus, which is characterized by sound modulations with neck or mandible movements, is frequently associated with temporomandibular joint dysfunction, but it is not pathognomonic of such a disorder. In such cases, functional therapy of the temporomandibular joint should be part of the multidisciplinary rehabilitation of patients with tinnitus. Copyright © 2016 Elsevier Masson SAS.

    The temporo-mandibular joint is distinguished from most other synovial joints of the body by two features: 1. the two jointed components carry teeth whose position and occlusion introduce a very strong influence on the movements of the temporo-mandibular joint and 2. its articular surfaces are not covered by hyaline cartilage, but by a dense, fibrous tissue. This paper describes the parts of the temporo-mandibular joint: the articular surfaces (the condylar process of the mandible and the glenoid part of the temporal bone), the fibrocartilaginous disc which is interposed between the mandibular and the temporal surface, the fibrous capsule of the temporo-mandibular joint and the ligaments of this joint. All these parts present a very strong adaptation at the important functions of the temporo-mandibular joint.

    The objective was to compare and correlate disability, pain intensity, the impact of headache on daily life and the fear of movement between subgroups of patients with chronic temporomandibular disorder (TMD). A cross-sectional study was conducted in patients diagnosed with chronic painful TMD. Patients were divided into: 1) joint pain (JP); 2) muscle pain (MP); and 3) mixed pain. The following measures were included: Craniomandibular pain and disability (Craniofacial pain and disability inventory), neck disability (Neck Dsiability Index), pain intensity (Visual Analogue Scale), impact of headache (Headache Impact Test 6) and kinesiophobia (Tampa Scale of Kinesiophobia-11). A total of 154 patients were recruited. The mixed pain group showed significant differences compared with the JP group or MP group in neck disability (p craniomandibular pain and disability (p Neck disability was a significant covariate (37 % of variance) of craniomandibular pain and disability for the MP group (β = 0.62; p neck disability (β = 0.40; p craniomandibular pain and disability. Mixed chronic pain patients show greater craniomandibular and neck disability than patients diagnosed with chronic JP or MP. Neck disability predicted the variance of craniofacial pain and disability for patients with MP. Neck disability and kinesiophobia predicted the variance of craniofacial pain and disability for those with chronic mixed pain.

    Full Text Available Temporomandibular disorder (TMD is an inclusive term in which those conditions disturbing the masticatory function are embraced. It has been estimated that 33% of the population have signs of TMD, but less than 5% of the population will require treatment. The objective of this study was to measure the frequency of TMD in rheumatoid arthritis (RA, osteoarthrosis (OA, ankylosing spondylitis (AS and systemic lupus erythematosus, and to define the limitations in everyday’s life that patients perceive when present. A six-month survey of consecutive outpatients in a rheumatology clinic in a teaching hospital in Mexico was carried out. We defined TMD as: 1 the presence of pain; 2 difficulty on mouth opening, chewing or speaking; 3 the presence of non-harmonic movements of the temporomaxilar joints. All three characteristics had to be present. Z test was used to define differences between proportions. We present the results of 171 patients. Overall, 50 patients had TMD according to our operational definition (29.24%. Up to 76% of the sample had symptoms associated with the condition. TMD is more frequent in OA and in AS (29.24% vs 38% OA, P=0.009; 39% AS; P=0.005. We found no association between the severity of TMD and the request for specific attention for the discomfort produced by the condition. Only 8 of 50 (16% patients with TMD had requested medical help for their symptoms, and they were not the most severe cases. TMD is more frequent in RA and OA. Although it may produce severe impairment, patients seem to adapt easily.

    The purpose of this study was to investigate the distribution and frequency of temporomandibular joint (TMJ) effusion in magnetic resonance (MR) images of patients with disc displacements. On T2 weighted MR images of 148 TMJs taken from 74 patients presenting with TMJ pain and dysfunction, we assessed the cases showing TMJ effusion, defined as an amount of fluid that exceeded the maximum amount seen in a control group of asymptomatic volunteers. The amount of TMJ fluid was graded as: I (none or minimal), II (moderate), III (marked), and IV (extensive), according to a standard set by a reference. Disc displacement categories were also recorded. Of the 148 TMJs examined in this study, 52 joints (35.1%) presented with joint effusion, 24 (16.2%) showing bilateral joint effusion. 38 joints showed upper joint space effusion, and 3 showed lower joint space effusion, and 11 showed both upper and lower joint space effusion. 96 joints (64.9%) had grade I joint fluid, 27 (18.2%) grade II, 15 (10.1%) grade III, and 10 (6.8%) grade IV. 80.0% of the joints presenting with grade IV effusion showed disc displacement without reduction. Joint effusion was found not only in upper, but also in lower joint spaces. The higher the effusion grade, the greater the frequency of disc displacement without reduction.

    Temporomandibular disorders (TMDs) are a major cause of non-dental orofacial pain with a suggested prevalence of 3% to 5% in the general population. TMDs present as unilateral or bilateral pain centered round the pre-auricular area and can be associated with clicking and limitation in jaw movements. It is important to ascertain if there are other comorbid factors such as headaches, widespread chronic pain and mood changes. A biopsychosocial approach is crucial with a careful explanation and self-care techniques encouraged.

    Stock prosthetic temporomandibular joint replacements come in limited sizes, and do not always encompass the joint anatomy that presents clinically. The aims of this study were twofold. Firstly, to design a personalized prosthetic total joint replacement for the treatment of a patient's end-stage temporomandibular joint osteoarthritis, to implant the prosthesis into the patient, and assess clinical outcome 12-months post-operatively; and secondly, to evaluate the influence of changes in prosthetic condyle geometry on implant load response during mastication. A 48-year-old female patient with Grade-5 osteoarthritis to the left temporomandibular joint was recruited, and a prosthesis developed to match the native temporomandibular joint anatomy. The prosthesis was 3D printed, sterilized and implanted into the patient, and pain and function measured 12-months post-operatively. The prosthesis load response during a chewing-bite and maximum-force bite was evaluated using a personalized multi-body musculoskeletal model. Simulations were performed after perturbing condyle thickness, neck length and head sphericity. Increases in prosthetic condyle neck length malaligned the mandible and perturbed temporomandibular joint force. Changes in condylar component thickness greatly influenced fixation screw stress response, while a more eccentric condylar head increased prosthetic joint-contact loading. Post-operatively, the prosthetic temporomandibular joint surgery reduced patient pain from 7/10 to 1/10 on a visual analog scale, and increased intercisal opening distance from 22 mm to 38 mm. This study demonstrates effectiveness of a personalized prosthesis that may ultimately be adapted to treat a wide-range of end-stage temporomandibular joint conditions, and highlights sensitivity of prosthesis load response to changes in condylar geometry.

    This study was designed to investigate the efficacy of the temporomandibular joint arthrocentesis with and without injection of sodium hyaluronate (SH) in the treatment of temporomandibular joint disorders. A total of sixty two TMJs in 34 males and 28 females aged 20-65 years comprised the study material. The patients' complaints were limited mouth opening, TMJ pain, and joint noises during function. Patients were randomly divided into 2 groups in which arthrocentesis plus intra-articular injection of sodium hyaluronate was performed in 1 group and only arthrocentesis was performed in the other group. Both groups contained patients with disc displacement with reduction and without reduction. Clinical evaluation of the patients was done before the procedure, immediately after the procedure, at 1 week and 1, 3 and 6 months postoperatively. Intensity of TMJ pain was assessed using visual analog scales. Maximal mouth opening and lateral jaw movements also were recorded at each follow-up visit. Both techniques increased maximal mouth opening, lateral movements, and function, while reducing TMJ pain and noise. Although patients benefitted from both techniques, arthrocentesis with injection of SH seemed to be superior to arthrocentesis alone.

    Establishing the patient's clinical diagnosis depends on gathering as much information of the patient and his or her signs and symptoms as possible. This information can be gathered from history, physical and psychological examination, diagnostic analysis. It is also important to look upon pain as a disorder and to consider the relationship between pain and psychological factors. The differential diagnosis is constructed through a biopsychological model of illness rather than through a more traditional biomedical model of disease. To arrive at a consistently accurate clinical diagnosis in patients with TMJ and craniofacial pain, the technique of clinical diagnosis must be well defined, reliable and include examination of the head and the neck, cranial nerves and the stomatognathic system. The craniomandibular index provides a standardized examination of the stomatognathic system that has been tested on validity and reliability. This chapter focuses on the techniques of history taking clinical and psychological examination and diagnostic criteria for temporomandibular joint disorders and muscle pain.

    Computed tomography (CT) of the temporomandibular joint (TMJ) was compared with hypocycloidal tomography in 30 joints of 15 adults with rheumatic disease. CT included 1.5 mm thick axial scans (at 1.0 mm intervals) with reformatted oblique sagittal and oblique coronal sections. Multisection (at 2.0 mm intervals) tomography included oblique sagittal and occasionally, oblique coronal sections. CT demonstrated bone abnormalities in 21 and tomography in 20 joints, indicating high agreement between the imaging modalities regarding number of abnormal TMJs. Bone structures were, however, better visualized by multiplanar CT due to superior contrast and spatial resolution particularly in the most lateral and medial parts of the joint, indicating superiority of CT for depicting subtle bony TMJ abnormalities in patients with rheumatic disease.

    Hematic cyst refers to accumulation of blood or blood breakdown products in a non epithelium-lined fibrous tissue capsule. Hepatic cyst is a term often used for deeply placed, incompletely resorbed hematoma hemorrhagic cyst, which may remain unchanged and unidentified for long periods of time. Trauma is the major causative factor, although it is often vague or totally uncalled by the patient. Chronic hematic cysts are uncommon lesions those can present diagnostic challenge. In this article we report a first case of a chronic hematic cyst of the temporomandibular joint TMJ. (author)

    Temporo-Mandibular Joints (TMJ) and orthognathic surgery are closely linked. In the past, some authors have even described (with mixed results) the correction of some dysmorphosis through direct procedures on the TMJs. Nowadays, performing orthognathic surgery involves the TMJ in three different occasions: (1) TMJ disorders potentially responsible for dento-maxillary dysmorphosis, (2) effects of orthognathic surgery on TMJs, and (3) condylar positioning methods in orthognathic surgery. These three chapters are developed in order to focus on the close relationships between TMJ and orthognathic surgery. Some perspectives close this article. Copyright © 2016 Elsevier Masson SAS.

    The most frequent symptom of craniomandibular dysfunction is pain in the preauricular area or in the temporo-mandibular joint, usually localized at the level of the masticatory musculature. Patients sometimes also complain of reflect otalgia, headaches and facial pain. Osteoarthrosis is a frequent degenerative debilitating chronic disorder that can affect the temporomandibular joint. It causes pain and articular rigidity, a reduction in mobility, and radiological alterations are visible in stratigraphy. The aim of this study was to compare the efficacy of a topically applied non-steroid anti-inflammatory drug that has recently become commercially available (diclofenac sodium in a patented carrier containing dimethyl sulfoxide, that favours transcutaneous absorption) which is commonly used to alleviate pain in knee or elbow joints, versus oral diclofenac, in the treatment of symptoms of temporomandibular joint dysfunction. Dysfunction of the temporomandibular joint was diagnosed in 36 adult patients. The patients were randomized in two age- and gender -matched groups. Group A (18 patients) received oral diclofenac sodium administered after a meal in 50-mg tablets twice a day for 14 days. Group B (18 patients) received 16 mg/ml topical diclofenac (diclofenac topical solution, 10 drops 4 times a day for 14 days). All patients completed a questionnaire at the start and end of therapy. Patients were asked to quantify on a graded visual analogue scale and to reply to questions about the pain and tenderness of the temporomandibular joint and the functional limitation of mouth opening. Patients were also requested to report side-effects of the treatment. All patients showed relief from pain after treatment: the difference between the two groups was not significant (p > 0.05). Post-treatment, 16 patients of group A had epigastralgic symptoms. Three patients treated with topical diclofenac showed a modest irritation of the temporomandibular joint region, and disappeared

    Several diseases should be considered in the differential diagnosis of disorders affecting the temporomandibular joints. Internal derangement is the main condition responsible for pain related to this joint. Clinical signs may, though, be quite non-specific, and many other conditions present with similar and not infrequently indistinguishable signs and symptoms. In the present study, the authors describe several non-dysfunctional conditions affecting the temporomandibular joints through computed tomography and magnetic resonance imaging, emphasizing the importance of these imaging methods in the diagnosis of inflammatory, neoplastic and traumatic diseases of this region. Considering that clinical presentations are frequently non-specific, radiologists play a critical role in the differential diagnosis. (author)

    This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the chi2 test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p 0.05). Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

    Temporomandibular joint is one of the most complicated joints of the body and plays an important role in the head and neck system. One of the factors affecting the temporomandibular joint and lead to temporomandibular disorder is anxiety with all the events causing it. The aim of this study was to determine a relationship between anxiety and temporomandibular disorders. In this prospective study, subjects were randomly selected. One hundred and thirty pre-university students in Isfahan were evaluated with Ketel's test of anxiety, exam stress test and temporomandibular disorder questionnaires. The evaluation was done in two stages 10 months and 1 month prior to the university entrance exam (Konkour), clinical assessments consisted of masticatory muscles and sternocleidomastoid muscle palpation, temporomandibular joint palpation for pain and noise and its movement, and mouth opening limitations. The Wilcoxon rank test and paired t-test were used to analyze the data and the P value under 0.05 was considered significant. The level of anxiety and occurrence of temporomandibular disorders were increased between two stages and had the highest level in the second stage. There was a significant increase between two stages (Ptemporomandibular disorders and anxiety between the two stages can suggest a possible relationship between anxiety and temporomandibular disorders. Therefore, the effect of anxiety in triggering temporomandibular disorder symptoms is probable.

    The author analysed the bone changes, the positional relationships between condylar head and articular fossa, and the interrelationship between the bone changes and the abnormal position of condylar head, from 1,036 radiographs of 259 patients with temporomandibular joint arthrosis, which were obtained by the oblique-lateral transcranial projection and orthopantomograms. The results were as follows: 1. Among the radiographic bone changes of the temporomandibular joint arthrosis, deformity was 36..90% (217 cases), sclerosis 34.18% (201 cases), erosive change 25.58% (152 cases) and marginal proliferation 3.06% (18 cases) respectively. 2. In the positional changes between condylar head and articular fossa, the downward positioning of condylar head in centric occlusion was most frequent (36.90%), of which frequency was significantly higher than forward positioning (11.22%) and backward positioning (4.76%) in same condition. Also, radiographs showed that the enlargement of articular space showed higher frequency than its narrowing. In the opening position of mouth, the restrict ed movement of condylar head within articular fossa was most frequent (35.03%). The forward positioning and the downward positioning was 15.65% and 9.52% respectively. Also, radiographs revealed that the incomplete movement or no positional change of condylar head was most frequent. 3. In the interrelationship between bone changes and abnormal position of condylar head, deformity was 42.79% in the cases of downward positioning of condylar head in centric occlusion and 37.50% in those of normal positioning of condylar head in same condition. This revealed that deformity was most frequent bone change in above condylar positionings. However, erosive change was 34.62% in the cases of downward positioning of condylar head in centric occlusion and 33 .33% in those of forward positioning.

    This study was performed to evaluate the relationship between pterygoid plate asymmetry and temporomandibular joint disorders. Cone-beam computed tomography (CBCT) images of 60 patients with temporomandibular disorders (TMD) involving pain were analyzed and compared with images of 60 age- and gender-matched controls. Three observers performed linear measurements of the lateral pterygoid plates. Statistically significant differences were found between measurements of the lateral pterygoid plates on the site that had pain and the contralateral site (p<0.05). The average length of the lateral pterygoid plates (LPPs) in patients with TMD was 17.01±3.64 mm on the right side and 16.21±3.51 mm on the left side, and in patients without TMD, it was 11.86±1.97 mm on the right side and 11.98±1.85 mm on the left side. Statistically significant differences in the LPP length, measured on CBCT, were found between patients with and without TMD (p<0.05). The inter-examiner reliability obtained in this study was very high for all the examiners (0.99, 95% confidence interval: 0.98-0.99). Within the limits of the present study, CBCT lateral pterygoid plate measurements at the side with TMD were found to be significantly different from those on the side without TMD. More research is needed to explore potential etiological correlations and implications for treatment.

    Full Text Available Background: Temporomandibular joint (TMJ ankylosis or hypomobility involves fusion of the mandibular condyle to the base of the skull. It is a major clinical problem that affects many patients suffering from facial trauma, infection, or systemic disease. The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence. Case Report: This report describes a case of a 4-year-old boy with inability to open mouth, diagnosed with unilateral right bony TMJ ankylosis. The surgical approach consisted of gap arthroplasty followed by vigorous physiotherapy. Conclusion: A detailed history, clinical and functional examination, radiographic examination facilitating correct diagnosis followed by immediate surgical intervention, and physiotherapy can help us to restore physical, psychological, and emotional health of the child patient.

    To determine whether there is a relationship between abnormal temporomandibular joint radiographic findings and age or gender in a sample of preorthodontic patients. Individualized corrected sagittal tomographs of 188 temporomandibular joints in 94 preorthodontic patients, aged 11 to 29 years, were taken and viewed by an observer blinded to clinical records. The study population was divided into 2 aged groups (11-15 years and 16-29 years) for comparative purpose. Temporomandibular joint radiographic findings were classified as normal or abnormal. There was no difference in ratio of abnormal to normal findings between the both aged groups. The frequency of osseous abnormalities was similar with that of abnormalities of condylar position. Abnormalities in CP and JS were most frequent in all aged groups. There is no significant difference between ages or genders for temporomandibular joint radiographic abnormalities.

    Psychological assessment has been used successfully to predict patient outcomes after cardiothoracic and bariatric surgery. The purpose of this study was to determine whether preoperative psychological assessment could be used to predict patient outcomes after temporomandibular joint arthroscopy. Consecutive patients with temporomandibular dysfunction (TMD) who could benefit from arthroscopy were enrolled in a prospective cohort study. All patients completed the Millon Behavior Medicine Diagnostic survey before surgery. The primary predictor variable was the preoperative psychological scores. The primary outcome variable was the difference in pain between the pre- and postoperative periods. The Spearman rank correlation coefficient and the Pearson product-moment correlation were used to determine the association between psychological factors and change in pain. Univariable and multivariable analyses were performed using a mixed-effects linear model and multiple linear regression. A P value of .05 was considered significant. Eighty-six patients were enrolled in the study. Seventy-five patients completed the study and were included in the final analyses. The mean change in visual analog scale (VAS) pain score 1 month after arthroscopy was -15.4 points (95% confidence interval, -6.0 to -24.7; P psychological factors was identified with univariable correlation analyses. Multivariable analyses identified that a greater pain decrease was associated with a longer duration of preoperative symptoms (P = .054) and lower chronic anxiety (P = .064). This study has identified a weak association between chronic anxiety and the magnitude of pain decrease after arthroscopy for TMD. Further studies are needed to clarify the role of chronic anxiety in the outcome after surgical procedures for the treatment of TMD. Copyright © 2015. Published by Elsevier Inc.

    Full Text Available This paper describes a case of a young patient who sought help because of pain in the right temporomandibular joint (TMJ. She also reported increasing of pain during chewing. Clinical examination revealed limited mouth opening with uncorrected deviation to the ipsilateral side. Palpation of the lateral pole of the right condyle discovered crepitus, and maximum assisted opening elicited a report of “familiar pain”. The diagnosis of osteoarthritis of the TMJ (RDC / TMD criteria, Axis I, Group III was confirmed by CBCT of TMJ. There is no “gold standard” for the management of TMD, but the need for TMD treatment has to be based on precise indications related to the presence of pain, limitation in function of the lower jaw and signs of degenerative joint disease. Conservative, reversible therapeutic procedures are considered as the first choice for TMD treatment and their task is to improve the function of the entire masticatory system. In this case patient was treated with the combination of physical therapy and stabilization splint, in order to reduce the pain and restore the normal function of the lower jaw. At 6 months’ follow-up symptoms have almost completely disappeared, while 3 years later, the patient still has no significant subjective symptoms. In the present case non-invasive therapy was sufficient to bring, otherwise recurrent nature of osteoarthritis, in complete remission and keep it like that for years.

    To evaluate the impact of headache in adults with masticatory myofascial pain (MMP) on the outcome variables clinical pain (ie, self-reported pain intensity and pressure pain sensitivity), sleep quality, and pain catastrophizing. A total of 97 patients with MMP were diagnosed with co-existing headache (MMPH group, n = 50) or without headache (MMP group, n = 47) according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The outcome parameters were the Pittsburgh Sleep Quality Index (PSQI); the Catastrophizing Thoughts subscale of the Pain-Related Self-Statement Scale (PRSS-C); pressure pain thresholds (PPTs) of the masseter and anterior temporalis muscles; and self-reported facial pain intensity measured on a 0- to 10-cm visual analog scale (VAS). Student t test for independent samples (α = 1.2%) and factorial analysis of variance (ANOVA) (α = 5%) were used to analyze the data. The MMPH group showed significantly impaired sleep quality (mean ± standard deviation [SD] PSQI score 9.1 ± 3.5) compared with the MMP group (7.2 ± 3.4; P = .008). Subscale scores on the PRSS-C were significantly higher in the MMPH (2.1 ± 1.2) than in the MMP group (1.6 ± 1.4, uncorrected P = .048). Also, the PPTs (kgf/cm²) of the masseter and anterior temporalis muscles were significantly lower in the MMPH group (1.52 ± 0.53; 1.29 ± 0.43, respectively) than in the MMP group (2.09 ± 0.73; 1.70 ± 0.68, respectively; P headache patients had lower PPTs in the anterior temporalis muscle (P = .041) in comparison with non-headache patients. Co-existence of headache further exacerbates clinical characteristics in patients with painful TMD, which implies involvement of common mechanisms and pathways of vulnerability in these patients.

    Magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) has now been established as a procedure of choice in the evaluation of TMJ disorders. In this study, we evaluated the dynamics of TMJ motion on MR imaging, which resembles arthrography. Sixty-eight TMJs in 38 symptomatic patients and one healthy volunteer were examined using pseudodynamic images with gradient echo sequences using a 0.5 Tesla MR unit and 8 cm circular planar surface coil. For depiction of each compartment of the meniscus, the optimum sequence was 200/15/2 (TR/TE/excitations) with 50 deg or 60 deg flip angle in gradient refocused acquisition in steady-state (GRASS) sequences. Three contiguous slices on sagittal MR images were routinely obtained at 14-18 different phases of the opening cycle and displayed in closed-loop cine fashion. Internal derangement was observed in 57% of 68 joints. The most common type was anterior meniscal displacement without reduction. Sideway and rotational displacements, observed in 10% each, were noted on both sagittal multislice images and axial reference images. As a pseudodynamic MR technique, jaw movement specifically designed to check bite procedure to adjust splints is useful for detecting the exact time of meniscal redisplacement on the second click. After conservative therapy for arthrosis, pseudodynamic MR provided information on changes in the meniscus and condylar relationship. Pseudodynamic MR with multiple phases is suitable for evaluating subtle motion abnormality of the meniscus and for post-therapeutic monitoring. (author)

    This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the chi2 test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p<0.05). However, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ (G1) was not related to joint effusion in TMD patients (p>0.05). Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

    Temporomandibular joint (TMJ) is one of the most complex joints of the human body. Due to its unique movement, in terms of combination of rotation and translator movement, disc of the joint plays an important role to maintain its normal function. In order to sustain the normal function of the TMJ, disc must be kept in proper position as well as maintain normal shape in all circumstances. Once the disc is not any more in its normal position during function of the joint, disturbance of the joint can be occurred which will lead to subsequent distortion of the disc. Shape of the disc can be influenced by many factors i.e.: abnormal function or composition of the disc itself. Etiology of the internal derangement of the disc remains controversial. Multifactorial theory has been postulated in most of previous manuscripts. Disc is composed of mainly extracellular matrix. Abnormal proportion of collagen type I & III may also leads to joint hypermobility which may be also a predisposing factor of this disorder. Thus it can be recognized as local manifestation of a systemic disorder. Different treatment modalities with from conservative treatment to surgical intervention distinct success rate have been reported. Recently treatment with extracellular matrix injection becomes more and more popular to strengthen the joint itself. Since multifactorial in character, the best solution of the treatment modalities should be aimed to resolve possible etiology from different aspects. Team work may be indication to reach satisfied results. Copyright © 2018. Published by Elsevier Taiwan.

    Full Text Available Temporomandibular joint disorders are disturbances of mastication system due to one or more component of mastication system does not properly function. The factors that play a role in this problem divided into three factors; a predisposition factor (systemic, occlusion disturbances and psychological trouble, b initiation factor (traumatic and c perpetuation factor (social behavior. These disorders are able to cause a variety of symptom suck as limitedness of jaw movement, clicking, deviation locked joint, muscle pain, joint pain, jaw movement pain and pain of ear and headache. The objective of this study was to obtain information about the prevalence degree of severity of the temporomandibular joint disorder, the differences of prevalence between man and woman and the different among age groups. The study was descriptive and analysis survey, done to 134 patients as an experimental sample of 3–75-year old that have visited Dental Hospital, Padjadjaran University Bandung, during February 2008. Sample consist of 57 men and 77 women were evaluated by using Helkimo Index and analysis by using Z statistical proportion test to know the existence of difference prevalence degree of severity between man and woman and using the chi-square test to know the difference prevalence among age groups.The result of this study shows that there is highly prevalence severity of temporomandibular joint disorder (84,33% and significantly different on prevalence severity between man and woman and among a group of ages.The conclusion can be drawn that patients who visited the dental hospital, Padjadjaran University have higher prevalence severity of temporomandibular joint disorder where a woman has higher level compare to man, and the young adult group has highest either man and woman. Clicking is the most often symptom appear to man and woman.

    Correction of severe malocclusions with skeletal discrepancies requires orthodontic treatment in combination with orthognathic surgery. Even though conventional orthognathic surgery (COS) is a common and well-accepted approach its influence on the signs and symptoms of temporomandibular disorders (TMDs) is still debated. Recently with the introduction of surgery first approach, a different timing for the management of dentoskeletal imbalances has been proposed. The present study is aimed at assessing the relationship between surgery first approach and temporomandibular joint (TMJ) disorders. The study sample consisted of 24 patients who were selected to be treated with surgery first approach. Clinical follow-ups after surgery were performed every week for the first month, at 3 months, 6 months, and at 1 year. A radiological follow-up was performed at 1 week and at 1 year after the operation with a panorex and a latero-lateral teleradiograph. To assess the effect of surgery first approach on the TMDs signs and symptoms, a clinical assessment was performed 4 days before surgery (T1), 6 months after surgery (T2), and 1 year postoperatively (T3). The results of the authors' study show that pain assessment revealed a general improvement of this symptom in correspondence to TMJ and masticatory muscles except in the masseter and neck region. Also joint noises, TMJ functioning, migraine, and headache underwent a considerable improvement. Surgery first approach is an innovative orthognathic procedure and, by undergoing surgery first approach, patients with pre-existing TMJ dysfunction may experience a significant improvement or even resolution of the TMDs signs and symptoms.

    The objective of this study was to determine the extent to which altered loading in the temporomandibular joint (TMJ), as might be associated with a malocclusion, drives degeneration of articulating surfaces in the TMJ. We therefore sought to quantify the effects of altered joint loading on the mechanical properties and biochemical content and distribution of TMJ fibrocartilage in the rabbit. Altered TMJ loading was induced with a 1mm splint placed unilaterally over the maxillary and mandibular molars for 6 weeks. At that time, TMJ fibrocartilage was assessed by compression testing, biochemical content (collagen, glycosaminoglycan (GAG), DNA) and distribution (histology), for both the TMJ disc and the condylar fibrocartilage. There were no changes in the TMJ disc for any of the parameters tested. The condylar fibrocartilage from the splinted animals was significantly stiffer and the DNA content was significantly lower than that in control animals. There was significant remodeling in the condylar fibrocartilage layers as manifested by a change in GAG and collagen II distribution and a loss of defined cell layers. A connection between the compressive properties of TMJ condylar fibrocartilage after 6 weeks of splinting and the changes in histology was observed. These results suggest a change in joint loading leads to condylar damage, which may contribute to pain associated with at least some forms of TMJ disease. Copyright © 2014 Elsevier Ltd.

    To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings. Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion. Logistic regression analyses were performed with the radiographic findings as the dependent variables and the following clinical variables as independent variables: opening pattern, maximal jaw opening, TMJ sounds, number of painful muscle/TMJ sites, duration of pain, presence of arthritic disease, depression and somatization scores, graded chronic pain, and age and gender. Coarse crepitus on opening/closing (odds ratio [OR] > or = 3.12), on lateral excursions (odds ratio > or = 4.06), and on protrusion (OR > or = 5.30) was associated with increased risk of degenerative findings in tomograms. A clinical diagnosis of osteoarthritis increased the risk of radiographic findings (OR > or = 2.95) and so did increasing age (OR > or = 1.03 per year) and the female gender (OR > or = 2.36). Maximal assisted opening and maximal opening without pain (position (OR > or = 2.60). No other significant associations were observed. Age, gender, and coarse crepitus, but no pain-related variables, were associated with increased risk of degenerative findings in TMJ tomograms. Maximal opening < 40 mm was associated with a posterior condyle-to-articular tubercle relation on opening.

    Introduction: The temporomandibular joint (TMJ) forms the very cornerstone of craniofacial integrity and its ankylosis in a growing child may cause problems in daily food intake, speech, appearance, and oral hygiene is affected to a major extent. It is one of the common acquired pathologies afflicting the skeleton. It is also the most overlooked and under-managed problem in children. Materials and Methods: A house to house survey was conducted between 2010 and 2011 in rural and urban areas of Lucknow. A total of 21,720 children aged between 3-15 years from 9090 houses comprising a representative sample were included. Results: Ten TMJ ankylosis cases were identified in 21,720 children. Of these, six were bilateral and four were unilateral. Male to female ratio was 1:9, with most patients (70.0%) being in the 10-15 years’ age group (mean age was 11.1 years ± 3.34). The most common cause of ankylosis was trauma for 90.0% of cases. The majority of patients (70%) were reporting the condition for the first time, with 30% patients having had previous treatment. Conclusion: TMJ ankylosis is an acquired condition in most of the cases. Birth/childhood trauma would be the major causative factor. Knowledge amongst parents, providers of health about this entity was poor. Initial management of the causative factor was poor. Mere knowledge among the general population and healthcare providers can result in primary prevention and also secondary prevention along with its successful definitive treatment. PMID:23251054

    Recurrent pains of the temporomandibular joint represent a frequent symptom with numerous different causes. CT and MRI can reliably show the cause of these disorders and therefore have substituted conventional X-ray imaging. Modern multi-slice-CT (MSCT) allows for examination of the skull base including the mandible in a very short time with thinnest slice collimation (0.75 mm). With 2D- and 3D- reformations reconstructed out of this volume data set in parasagittal, coronal or any other arbitrary slice orientation excellent imaging of fractures and bony changes of arthrosis as well as benign and malignant tumors of the temporomandibular joint can be performed. MRI offers very good soft tissue contrast in order to visualize the intra-articular disc, the ligaments and muscles, as well the possibility to acquire cross sectional images in any user-defined orientation. MRI is the method of choice to diagnose 'internal derangement', particularly displacement of the intra-articular disc and inflammatory disease of the temporomandibular joint. The present paper will provide diagnostic strategies for the use of MSCT or MRI imaging concerning the different causes of disorders to the temporomandibular joint. (orig.)

    The radiation exposure caused by standardized examinations of the temporomandibular joint has been determined with the aid of 660 exposures of an Alderson phantom. Comparative examinations were performed with the classic contact technique according to Parma to elucidate the results obtained. The lowest surface exposure was observed in contact examinations of the temporomandibular joint. Application of a flat cone led to a 13-fold reduction in surface exposure compared to contact examinations according to Parma. Furthermore, radiation exposure strongly decreased from the irradiation field to the adjacent area if a cone (flat cone and ear cone) was used. (author)

    Thirty patients with temporo-mandibular joint dysfunction were selected to investigate the changes in otoacoustic emissions before and after conservative treatment of their temporo-mandibular joints. Pure tone audiometry, transient-evoked otoacoustic emissions (TEOAE), distortion-product otoacoustic emissions (DPOAE) as well as a tinnitus questionnaire were administered to all patients before and after therapy. Therapy was conservative in the form of counselling, physiotherapy, anti-inflammatory agents, muscle relaxants, and occlusal splints. Results indicated insignificant changes in the TEOAEs, whereas there were significant increases in distortion product levels at most of the frequency bands. These results were paralleled to subjective improvement of tinnitus.

    The purpose of this study was to quantitatively evaluate contrast enhancement effects of the posterior disk attachment in the temporomandibular joint arthrosis using dynamic MRI with bilateral surface coils. One hundred twenty-four temporomandibular joints in 96 symptomatic patients and 27 control subjects were examined with a spoiled GRASS pulse sequence (TR: 35 ms, TE: 8 ms, flip angle: 60deg). One sagittal scan was performed prior to injection, then 0.1 mmol/kg of Gd-DTPA was given as a rapid bolus injection, immediately after which scans were performed at 30 seconds intervals for a period of 5 minutes. Signal intensity (SI) was measured from the ROI of the posterior disk attachment region. The contrast enhancement effects may be calculated by SI ratio (SIR) = ( SI[sup post]-SI[sup pre])/SI[sup pre], where SI[sup post] and SI[sup pre] were the signal intensities after and before administration of contrast medium. The time intensity curve of SIR versus time after injection was obtained on each symptoms. Join pain group (85 joints) tended to show a rapid enhancement pattern, while control group (54 joints), joint sound or opening limitation group (39 joints), and asymptomatic group (68 joints) showed a relatively gradual enhancement pattern. The drop of SIR in four groups were hardly observed during examination. Mean peak SIR of control group, joint pain group, joint sound or opening limitation group, and asymptomatic group was 0.62[+-]0.24 (SD), 1.53[+-]0.69, 0.73[+-]0.38 and 0.78[+-]0.44 respectively. The mean SIR of pain group was significantly (P<0.001, t-test) higher than that of other groups. These results suggested that dynamic MRI of the temporomandibular joint may effectively depict the inflammatory changes of the posterior disk attachment. (author).

    For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosis as rheumatoid arthritis through the clinical, radiographic examination and laboratory finding. Temporoman dibular joint involvement was evaluated through the clinical, radiographic examination. The results were as follows; 1. TMJ was involved in 15 patients of 30 patients with rheumatoid arthritis. (50% involvement). 2. Duration of rheumatoid arthritis was more longer in patients with TMJ involvement than in patients without TMJ involvement. 3. Osseous changes in TMJ were in order of frequency erosion, flattening, osteophyte, sclerosis, deformity, and most common involved site was mandibular condyle. 4. Most common positional change of condyle was forward position in centric occlusion, and restricted movement of condyle in 1 inch mouth opening. 5. TMJ involvement of rheumatoid arthritis was almost bilateral. 6. Main symptoms of TMJ were pain, stiffness, tenderness, limitation of mouth opening, crepitation. 7. There was not the case of ankylosis. 8. There was statistically insignificant correlation between mandibular deviation and TMJ involvement, but some cases showed severe deviation on mouth opening.

    Temporo-mandibular joint (TMJ) dislocation is an unusual complication of transoesophageal echocardiography (TEE). We report a rare case of bilateral TMJ dislocation in an 84-year-old man prior to DC cardioversion (DCCV) for atrial flutter. Shortly after TEE and DCCV, the patient complained of bilateral facial pain. An orthopantomogram revealed bilateral TMJ dislocation. A closed reduction was performed by maxillo-facial surgeons under intravenous anaesthesia. Although very uncommon, the physician should be aware of the complication and its management.

    To determine the relationship between clinical symptoms and magnetic resonance (MR) images in patients presenting with temporomandibular joint (TMJ) disorders. This study was based on 172 joints in 86 patients presenting with TMJ disorders. Joint pain and sound during jaw opening and closing movements were recorded, and the possible relationship between disc positions and bony changes of the condylar head and the articular fossa in MR images in the oblique sagittal planes were examined. Data were analyzed by Chi-square test. There was no statistically significant relationship between clinical symptoms and MR images in the patients with TMJ disorders. In the patient with TMJ disorders, joint pain and sound could not be specific clinical symptoms that are related with MR image findings, and asymptomatic joint did not necessarily imply that the joints are normal according to MR image findings.

    The most significant otologic symptoms, consisting of ear pain, tinnitus, dizziness, hearing loss and auricolar "fullness", generally arise within the auditory system, often are associated with extra auricolar disorders, particularly disorder of the temporo-mandibular joint. In our study we examined a sample of 200 consecutive patients who had experienced severe disabling symptom. The patiens came to maxillofacial specialist assessment for temporomandibular disorder. Each patient was assessed by a detailed anamnestic and clinical temporomandibular joint examination and they are divided into five main groups according classification criteria established by Wilkes; tinnitus and subjective indicators of pain are evaluated. The results of this study provide a close correlation between the joint pathology and otologic symptoms, particularly regarding tinnitus and balance disorders, and that this relationship is greater the more advanced is the stage of joint pathology. Moreover, this study shows that TMD-related tinnitus principally affects a younger population (average fifth decade of life) and mainly women (more than 2/3 of the cases). Such evidence suggests the existence of a specific tinnitus subtype that may be defined as "TMD-related somatosensory tinnitus".

    2007-03-01

    Complex regional pain syndrome (CRPS) is a chronic condition characterized by intense pain, swelling, redness, hypersensitivity and additional sudomotor effects. In all 13 cases of CRPS in the head and neck region reported in the literature, nerve injury was identified as the etiology for pain initiation. In this article, we present the case of a 30-year-old female patient with sympathetically maintained pain without apparent nerve injury. Her main symptoms--left-side preauricular pain and inability to open her mouth wide--mimicked temporomandibular joint arthralgia and myofascial pain of the masticatory muscles. Later, symptoms of intermittent preauricular pain and swelling developed, along with hyposalivation, which mimicked parotitis. After an extensive diagnostic process, no definitive underlying pathology could be identified and a diagnosis of neuropathic pain with a prominent sympathetic component was made. Two years after the onset of symptoms and initiation of care, treatment with repeated stellate ganglion blocks and enteral clonidine pharmacotherapy provided adequate pain relief.

    Anterior disc displacement (ADD) of temporomandibular joint (TMJ) is regarded as one of the major findings in temporomandibular disorders (TMD). It is related to joint noise, pain, mandibular dysfunction, degenerative change and osteoarthritis. In the mean time, the pathological changes were found in synovial membrane and synovial fluid. Hyaluronic acid is a principal component of the synovial fluid which plays an important role in nutrition, lubrication, anti-inflammation and cartilage repair. The synthesis, molecule weight, and concentration of hyaluronic acid are decreased during TMD and cause TMJ degenerative changes. The clinical conditions, pathological changes, the mechanism of action for hyaluronic acid and the treatment of anterior disc displacement of TMJ are discussed in this article.

    Disc and condylar position were observed on MRIs of temporomandibular joint disorder patients and condylar position agreement between MRI and tranascranal radiography was evaluated. MRI and transcranial radiographs of both TM joints from 67 patients with temporomandibular disorder were used. On MRI, the position and shape of disc and condylar position as anterior, middle, posterior was evaluated at medial, center, and lateral views. On transcranial radiographs, condylar position was evaluated using the shortest distance from condyle to fossa in anterior, superior, and posterior directions. 1. On MRI, 96 joints (71.6%) of 134 had anterior disc dispalcement with reduction and 38 joints (28.4%) without reduction. 2. Fourteen (14.6%) of 96 reducible joints showed anterior condylar position. 19 (19.8%) showed central position, 63 joints (65.6%) showed posterior position. Two joints (5.3%) of 38 non-reducible joints showed anterior condylar position, while 9 (23.7%) showed central position, and 27 (71.1%)-posterior position. 3. In 85 joints (63.4%) of 134, the transcranial condylar position agreed with that of the central MRI view, 10 joints (7.5%) with that of medial, 16 joints (11.6%) with that of lateral, and 23 joints (17.2%) disagreed with that of MRI. On MRI, most of the reducible and non-reducible joints showed posterior condylar position. Transcranial radiographs taken with machine designed for TMJ had better agreement of condylar position with that of MRI. Extremely narrow joint spaces or very posterior condylar positions observed on transcranial radiographs had a little more than fifty percent agreement with those of MRIs.

    Full Text Available Complicated tooth extractions may lead to various post-extraction complications, including Temporomandibular Joint Disorders (TMD. Despite of the rare incidence, a delayed treatment of the TMD will cause more problems in the future as well as increased morbidity rate. The purpose of the current study was to elaborate the symptoms as well as the management of TMD as a post tooth extraction complication. The types of TMD as a post tooth extraction complication includes dislocated condyle, osteoarthritis, fracture condyle and disc displacement. These type of complications may resulted from an extensive opening of the mouth as well as an over pressure on the mandible during tooth extraction. In relation to this, some of the TMD symptoms that might cause a certain level of interference for patients may include pain, limited mouth opening and joint sounds, with pain and limited mouth opening as the initial symptoms. The first measure of the pain management would be warm light compress around the TMJ followed by a soft diet for food intake. A definitive treatment should then be based on the diagnosis of the TMD. It is concluded that TMD may occur as a complication of a tooth extraction that initiated by pain and limited mouth opening. Immediate treatment would be pain relieve and load reduction of the Temporomandibular Joint by employing soft diet and mandibular movement restriction.

    The prevalence of temporomandibular disorders in patients with chronic whiplash-associated disorder is a controversial issue that may be influenced by the widespread pain character and psychologic distress frequently observed in patients with chronic pain. The aim of this study was to determine the prevalence of temporomandibular disorder pain, widespread pain, and psychologic distress in persons with chronic whiplash-associated disorder pain, using a controlled, single blind study design. The prevalence of temporomandibular disorder pain in the chronic whiplash-associated disorder pain group was compared with 2 control groups: a chronic neck pain group and a no neck pain group. From 65 persons, a standardized oral history was taken, a physical examination of the neck and the masticatory system was performed, widespread pain was investigated by tender point palpation, and psychologic distress was measured with a questionnaire (SCL-90). Because the recognition of temporomandibular disorder pain and neck pain remains a matter of debate, 3 well-defined classification systems were used: one based on the oral history, a second on a combination of oral history and pain on active movements and palpation, and a third one based on a combination of oral history and function tests. Irrespective of the classification system used, the chronic whiplash-associated disorder pain group more often suffered from temporomandibular disorder pain (0.001neck pain group. Moreover, patients with whiplash-associated disorder showed more psychologic distress (0.000disorder suggests that the higher prevalence of temporomandibular disorder pain in these patients is part of a more widespread chronic pain disorder.

    A finite element model of the temporomandibular joint (TMJ) and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc. A quasilinear viscoelastic model was used to simulate the behaviour of the disc. The viscoelastic nature of this tissue is shown to be an important factor when sustained (awake bruxism) or cyclic loading (sleep bruxism) is simulated. From the comparison of the two types of bruxism, it was seen that s...

    The objective of this study was to evaluate the MRI findings of the temporomandibular joint (TMJ) in patients with rheumatic disease. The characteristic MRI findings of the TMJs in rheumatic patients were considered the obscurity of temporal posterior attachment (TPA) visualization and the presence of osseous changes of the condyle. As for the osseous changes, nearly 50% of the condyles had erosive changes and 20% showed severe bone destruction. (author)

    Full Text Available Long-standing temporomandibular joint (TMJ dislocations persist for more than a month are most challenging to treat. The management of such condition varies widely, from closed reduction to complicated surgical procedures. The choice of an appropriate methodology is questionable. At present, there are no standard rules or conventions for the ideal strategy in different circumstances. This paper attempts to present the experience of managing two cases of long-standing TMJ dislocations.

    The aim of this evaluation was to examine correlations between internal derangement of the temporomandibular joint (TMJ) and cervical spine disorder (CSD). A prospective controlled clinical study was carried out. Thirty patients with signs and symptoms of internal derangement but without any subjective neck problems and 30 age- and gender-matched control subjects without signs and symptoms of internal derangement were examined. The investigation of the temporomandibular system was carried out using a 'Craniomandibular Index'. Afterwards an examiner-blinded manual medical investigation of the craniocervical system was performed. This included muscle palpation of the cervical spine and shoulder girdle as well as passive movement tests of the cervical spine, to detect restrictions in the range of movement as well as segmental intervertebral dysfunction. The internal derangement of the TMJ was significantly associated with 'silent' CSD (t-test, P temporomandibular system exhibited significantly more often pain on pressure of the neck muscles than patients without muscle tenderness of the temporomandibular system (t-test, P < 0.05). As a result of the present study, for patients with internal derangement of the TMJ an additional examination of the craniocervical system should be recommended.

    To evaluate the effect of total joint replacement in treatment of temporomandibular joint(TMJ) osteoarthropathy with stock prostheses. Six female patients involving 10 joints (2 unilateral and 4 bilateral), with an average age of 59 years old, were involved in this study. Three patients (5 joints) were diagnosed as internal derangement in V stage depending on MRI, 3D-CT findings and clinical characteristics. The other 3 patients (5 joints) had histories of failed temporomandibular joint operation using costochondral graft or temporalis fascial flap. The maximal mouth opening was 1.9 cm on average (range, 1.0 to 2.9cm). All the joints were replaced with Biomet standard prosthesis under general anesthesia. The follow-up period was from 7 to 49 months (average, 17.5 months). All the operations were successfully performed. Heterotopic ossification happened in a bilateral case 1 year postoperatively. One patient with bilateral joint disease complained of severe uncomfortable feeling in the region of the ears and the temples, although there was no significant positive signs according to an ENT examination. Pain relief of the joint and mouth opening improvement were significant in 4 patients. No failure was noted secondary to infection or loosening of the prostheses. The occlusal relationship kept stable postoperatively in all cases. Total TMJ joint replacement with standard prosthesis is a good choice for TMJ reconstruction. It can significantly reduce joint pain and the mouth opening limitation resulted from osteoarthritis. Long-term result remains to be evaluated based on a long-term follow-up.

    Injuries of the temporomandibular joint are mostly due to injuries or fractures of the mandibular condyle. Fractures of the skull base involving the temporomandibular joint are rare. Classification of fractures refers to their anatomical positions and the presence or absence of a luxation. Further, it is important whether the fracture is intra- or extra-capsular. The primary imaging method should be orthopantomography. As for therapy planning, especially surgery, also evaluation of soft tissue is necessary, computed tomography is the imaging method of choice. For diagnosis of complications or internal derangement of the temporomandibular joint, magnetic resonance imaging is to be recommended. (orig.) [German] Die Verletzungen des Kiefergelenks gehen zumeist mit einer Verletzung oder Fraktur des Kieferkoepfchens bzw. des Kiefergelenkfortsatzes einher. Frakturen der Schaedelbasis unter Beteiligung der Kiefergelenkpfanne sind selten. Unterschieden werden die Frakturen des Gelenkfortsatzes nach anatomischer Lokalisation und danach, ob eine Luxation vorhanden ist oder nicht. Weiter ist von Bedeutung, ob der Frakturspalt intraoder extrakapsulaer verlaeuft. Die primaere Bildgebung sollte mittels Orthopantomographie erfolgen. Da fuer eine weitere operative Behandlung auch die etwaige Verletzung der Weichteile von Bedeutung ist, bietet sich die Computertomographie als bildgebende diagnostische Methode an. Zur Abklaerung von Komplikationen bzw. des so genannten ''internal derangement'' ist die Magnetresonanztomographie zu empfehlen. (orig.)

    The influence of circulating serotonin (5-HT) on the effects of intra-articular administration of granisetron on temporomandibular joint (TMJ) pain was investigated in 11 patients with chronic polyarthritides. An analgesic effect superior to placebo has been shown previously. The change in TMJ movement pain intensity was negatively correlated to circulating 5-HT; that is, the higher the 5-HT before injection, the greater the reduction of pain intensity. The resting pain intensity reduction was not related to 5-HT. In conclusion, this study indicates a stronger short-term analgesic effect on TMJ movement pain by intra-articular administration of the 5-HT3 receptor antagonist granisetron in patients with high levels of circulating 5-HT.

    The occurrence of temporo-mandibular joint (TMJ) disease in ankylosing spondylitis is not widely recognized and its incidence is disputed. Seventy-nine patients attending two routine rheumatology clinics were therefore examined by dental surgeon and nine (11-5 per cent) were considered to have specific TMJ involvement. These patients were older than the remainder, and had more extensive spinal and peripheral joint disease. Symptoms were mild and the predominant clinical feature was restricted mouth opening, which could present considerable difficulties during emergency anaesthesia. Bilateral condylectomy was undertaken in one patient with some benefit. Images PMID:1124959

    This paper determines the prevalence of internal derangement (ID) of the temporomandibular joint (TM) in a population of children prior to orthodontic therapy. Thirty-two children, aged 7-15 years, with a variety of orthodontic disorders underwent both MR imaging and physical examination to assess ID of the TMJ. With MR imaging, the disks were graded as normal, borderline anterior displaced, or anterior displaced. Fifty-nine TMJs in 32 patients were successfully imaged. Five TMJ MR examinations could not be interpreted because of patient motion. Fifty seven of the 59 joints (97%) were normal. One disk (1.7%) was anterior displaced, and one (1.7%) was considered borderline

    The three-dimensional (3D) temporomandibular joint (TMJ) model derives from a study of the cranium by 3D virtual reality and mandibular function animation. The starting point of the project is high-fidelity digital acquisition of a human dry skull. The cooperation between the maxillofacial surgeon and the cartoonist enables the reconstruction of the fibroconnective components of the TMJ that are the keystone for comprehension of the anatomic and functional features of the mandible. The skeletal model is customized with the apposition of the temporomandibular ligament, the articular disk, the retrodiskal tissue, and the medial and the lateral ligament of the disk. The simulation of TMJ movement is the result of the integration of up-to-date data on the biomechanical restrictions. The 3D TMJ model is an easy-to-use application that may be run on a personal computer for the study of the TMJ and its biomechanics.

    This book covers the biostatistical methods utilized to interpret and analyze dental research in the areas of orofacial pain and temporomandibular disorders. It will guide practitioners in these fields who would like to interpret research findings or find examples on the design of clinical investigations. After an introduction dealing with the basic issues, the central sections of the textbook are dedicated to the different types of investigations in sight of specific goals researchers may have. The final section contains more elaborate statistical concepts for expert professionals. The field of orofacial pain and temporomandibular disorders is emerging as one of the most critical areas of clinical research in dentistry. Due to the complexity of clinical pictures, the multifactorial etiology, and the importance of psychosocial factors in all aspects of the TMD practice, clinicians often find it hard to appraise their modus operandi, and researchers must constantly increase their knowledge in epidemiology and ...

  8. Comparison of MRI findings with clinical symptoms in temporomandibular joint internal derangement

    To determine the clinical correlation of magnetic resonance imaging (MRI) findings of temporomandibular joint internal derangements. The MR images of 150 TMJs in 75 patients were analyzed. The clinical symptoms were pain in the pre auricular area and masticatory muscles and TMJ sounds. There was a statistically significant relationship between the MRI diagnoses of different types of disc displacements and clinical findings of pain, clicking, and crepitus. The risk of TMJ pain was increased when the disc displacement without reduction occurred at the same time in combination with the osteoarthrosis and effusion. Regardless of the results, the data indicate that each of these MR imaging variables may not be regarded as the unique and dominant factor in defining TMJ pain occurrence.

    Crepitus is an important sign for diagnosis of arthrosis of the temporomandibular joint (TMJ). The presence of crepitus can be evaluated by the listening test previously proposed by our group. However, TMJ can be diagnosed by MR imaging showing the disc position and related findings including bony changes and joint effusion. This study investigated the relationship between the presence of crepitus and pathology of the joint. Fourteen joints with crepitus diagnosed by the listening test were examined in this study. TMJ was categorized into four types based on findings on double spin echo MR images. The results were as follows: Of fourteen joints with crepitus, five (36%) were showed as normal superior disc position. The remaining 9 joints (64%) were diagnosed with disc displacement, of which, 6 showed reduction, one was without reduction and 2 without reduction were associated with arthrosis. Statistical analysis using the data obtained here and other data showed that the joints with crepitus tended to show disk displacement. There was no significant difference between the degree of certainty about the presence of the crepitus and the distribution of joint pathology. Joint effusion was observed only in the joints with displacement. These results indicated that TMJ with crepitus is associated with varied joint pathology. (author)

    We investigated the temporal association between temporomandibular disorders (TMD)-related symptoms and headache during TMD treatment for patients who fulfilled the diagnostic criteria for headache attributed to TMD (HATMD) specified in the Diagnostic criteria for TMD (DC/TMD) and International classification of headache disorders (ICHD)-3 beta. The study enrolled 34 patients with HATMD induced by masticatory myofascial pain but not by temporomandibular arthralgia. Facial pain intensity, the pressure pain threshold of pericranial muscles, and maximum unassisted opening of the jaw were assessed at an initial examination and before and after physical therapy. The intensity and frequency of headache episodes and tooth contact ratio were also recorded before and after the intervention. Headache intensity and frequency significantly decreased, and these reductions were temporally related to improvements in facial pain intensity, maximum unassisted opening, and pressure pain threshold during TMD treatment. Linear regression analysis showed significant correlations between facial pain intensity and headache intensity and between tooth contact ratio and pressure pain threshold. Among patients who fulfilled the DC/TMD and ICHD-3 beta diagnostic criteria for HATMD, headache improved during TMD treatment, and the improvement was temporally related to amelioration of TMD symptoms. These findings suggest that sensitization in the central and peripheral nervous systems is responsible for HATMD. (J Oral Sci 58, 195-204, 2016).

    Acute dislocation of the temporomandibular joint is a situation that, although rare, may present to the dentist in practice at any time. A number of activities, such as removal of a tooth, may cause dislocation. The event is painful and distressing for the patient, their family and the dental team. Prompt management minimises discomfort, distress and long-term morbidity to the patient. We describe the aetiology of acute dislocation and outline a number of techniques that will aid the clinican in dealing with this event.

    Until recently, CT investigation of temporomandibular joint (TMJ) disorders has been regarded as a sophisticated procedure. A method of investigation was developed that allows easy evaluation of axial scans. The method was evaluated in a series of 65 joints with arthrographically diagnosed internal derangements. In anterior disk displacement CT findings led to an identical diagnosis in 56 of 65 joints (sensitivity, 86%). In clinically asymptomatic joints investigated for other reasons, only one of 12 showed signs of internal derangement on CT (specificity, 92%). This conservative approach to CT evaluation of internal derangement seems to be as accurate as more sophisticated methods. It is easy to perform, requires no additional manpower or computer time, and has a very good reproducibility

    There is no reliable predictor for therapeutic efficacy for temporomandibular joint (TMJ) disease. The aim of the present study was to evaluate the usefulness of Tc-99m HDP bone scan in the pre-therapeutic assessment of prognosis for TMJ disease. Between January 2005 and July 2007, 94 patients (M: F=18: 76; mean age, 33.4±14.0 y) with TMJ disease who underwent pre-therapeutic bone scan were enrolled. Planar bone scan images were obtained at right and left lateral skull areas 3 hours post Tc-99m HDP injection (dose=1295 MBq). TMJ uptake of Tc-99m HDP was quantitated using 13X13 pixel-square region-of-interest over TMJ and parietal skull area as background. TMJ uptake ratio was calculated as; (TMJ background) / background. Asymmetric indices for involved TMJ uptake (Al invovle ) were defined as; TMJ uptake ratio of involved/non-involved joint. Asymmetric indices for greater TMJ uptake regardless of disease involvement (AI greater ) were defined as; TMJ uptake ratio of greater/smaller TMJ uptake. Splint therapy was applied to all patients with mean duration of 7 months (range; 3-34 months). Therapeutic efficacy was dichotomised as improved or non-improved in consideration of mandibular movement, TMJ noise, pain, and tenderness. Seventy-six patients experienced improvement, whereas 18 patients non-improvement. There was no significant difference between improved versus non-improved patients regarding TMJ uptake ratio of involved joint (2.92±0.82 vs. 2.91±0.66), and AI invovle (1.16±0.22 vs. 1.10±0.12) (p>0.05, t-test). However, AI greater was significantly higher in improved patients than non-improved patients (1.20±0.19 vs. 1.13±0.09, p<0.05, t-test). Regardless of disease involvement of TMJ disease, asymmetricities of Tc-99m HDP uptake were more frequently found in improved group after splint therapy. Tc-99m HDP bone scan can predict the efficacy of splint therapy in TMJ disease

    We conducted a genetic analysis of the developing temporo-mandibular or temporomandi-bular joint (TMJ), a highly specialized synovial joint that permits movement and function of the mammalian jaw. First, we used laser capture microdissection to perform a genome-wide expression analysis of each of its developing components. The expression patterns of genes identified in this screen were examined in the TMJ and compared with those of other synovial joints, including the shoulder and the hip joints. Striking differences were noted, indicating that the TMJ forms via a distinct molecular program. Several components of the hedgehog (Hh) signaling pathway are among the genes identified in the screen, including Gli2, which is expressed specifically in the condyle and in the disk of the developing TMJ. We found that mice deficient in Gli2 display aberrant TMJ development such that the condyle loses its growth-plate-like cellular organization and no disk is formed. In addition, we used a conditional strategy to remove Smo, a positive effector of the Hh signaling pathway, from chondrocyte progenitors. This cell autonomous loss of Hh signaling allows for disk formation, but the resulting structure fails to separate from the condyle. Thus, these experiments establish that Hh signaling acts at two distinct steps in disk morphogenesis, condyle initiation, and disk-condyle separation and provide a molecular framework for future studies of the TMJ.

    Necrotising otitis externa is associated with high morbidity and mortality rates. This study investigated whether temporomandibular joint involvement had any prognostic effect on the course of necrotising otitis externa in patients who had undergone hyperbaric oxygen therapy after failed medical and sometimes surgical therapy. A retrospective case series was conducted of patients in whom antibiotic treatment and surgery had failed, who had been hospitalised for further treatment and hyperbaric oxygen therapy. Twenty-three patients with necrotising otitis externa were identified. The temporomandibular joint was involved in four patients (17 per cent); these patients showed a constant gradual improvement in C-reactive protein and were eventually discharged free of disease, except one patient who was lost to follow up. Four patients (16 per cent) without temporomandibular joint involvement died within 90 days of discharge, while all patients with temporomandibular joint involvement were alive. Three patients (13 per cent) without temporomandibular joint involvement needed recurrent hospitalisation including further hyperbaric oxygen therapy; no patients with temporomandibular joint involvement required such treatment. Patients with temporomandibular joint involvement had lower rates of recurrent disease and no mortality. Therefore, we suggest considering temporomandibular joint involvement as a positive prognostic factor in necrotising otitis externa management.

    Accurate diagnosis of chronic pain disorders of the mouth, jaws, and face is frequently complex. It is common for patients with chronic orofacial pain to consult multiple clinicians and receive ineffective treatment before a correct diagnosis is reached. This problem is a significant public health concern. Clinicians can minimize error by starting the diagnostic procedure with a careful, accurate history and thorough head and neck examination followed by a thoughtfully constructed differential diagnosis. The possibility that the patient has symptoms of a life-threatening underlying disease rather than a more common dental, sinus, or temporomandibular disorder must always be considered.

    A finite element model of the temporomandibular joint (TMJ) and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc. A quasilinear viscoelastic model was used to simulate the behaviour of the disc. The viscoelastic nature of this tissue is shown to be an important factor when sustained (awake bruxism) or cyclic loading (sleep bruxism) is simulated. From the comparison of the two types of bruxism, it was seen that sustained clenching is the most detrimental activity for the TMJ disc, producing an overload that could lead to severe damage of this tissue.

    Full Text Available The present cross-sectional study was designed to investigate the association between sleep bruxism (SB, tinnitus and temporomandibular disorders (TMD. The sample consisted of 261 women (mean age of 37.0 years. The Research Diagnostic Criteria for Temporomandibular Disorders were used to classify TMD and self-reported tinnitus. SB was diagnosed by clinical criteria proposed by the American Academy of Sleep Medicine. The results showed an association between painful TMD and tinnitus (OR = 7.3; 95%CI = 3.50-15.39; p < 0.001. With regard to SB, the association was of lower magnitude (OR = 1.9; 95%CI = 1.16-3.26; p < 0.0163. When the sample was stratified by the presence of SB and painful TMD, only SB showed no association with tinnitus. The presence of painful TMD without SB was significantly associated with tinnitus (OR = 6.7; 95%CI = 2.64-17.22; p < 0.0001. The concomitant presence of painful TMD and SB was associated with a higher degree of tinnitus severity (OR = 7.0; 95%CI = 3.00-15.89; p < 0.0001. It may be concluded that there is an association between SB, painful TMD and self-reported tinnitus; however, no relationship of a causal nature could be established.

    We have presented two clinical case reports of patients with TMJ dysfunction syndrome as an example of coordinated treatments between dentists and physical therapists. The clinical profiles of these patients with craniocervical pain were compiled from comprehensive physical therapy and dental-orthopedic evaluations. The significance of the relationship between the rest position of the mandible and forward head posture has been shown by the changes observed after correction of the postural deviations and vertical resting dimensions by dental treatments and physical therapy. Additional research is necessary to determine long-term effects of this combined approach in TMJ dysfunction syndrome.

Methods: A cross-sectional study carried with 21 patients receiving physiotherapy care during the year of 2007 at the Center for Integrated Medical Care (Núcleo de Atenção Médica Integrada - NAMI, in Fortaleza-CE, Brazil. Those were submitted to anamnesis (age, presence of pain, affected sites and parafunctional habits and functional assessment (presence of trigger points, movement amplitude and postural evaluation. Results: The age varied from 16 to 56 years, with an average of 31.3 ± 14.85 and female gender was the most affected with 17 (81.0% patients. Of the assessed patients, 13 (61.9% presented pain of moderate intensity, with an average of 5.4 ± 0.50. The most common sites of pain were the temporomandibular joint (TMJ, reported by 15 (71.4%,and cervical region, reported by 13 (61.9% patients. We found that 13 (61.9% assessed patients reported clenching as parafunctional habit. Significant limitation of mouth opening and movements of the cervical region were observed when compared to normal values (p <0.05. The most painful muscles on palpation were upper trapezius (n=19, medial pterygoid (n=15 and the masseter (n=15. The TMJ presented strong pain (degree 3 on palpation in 3 (14.3% patients. In postural assessment, 10 (47.6% had cervical hyperlordosis, 7 (33% had forward head posture and 7 (33% had raised shoulders. Conclusion: Patients with TMJD receiving physical therapy present limitations in TMJ and cervical movement, pain, presence of trigger points and postural changes at a more compromised and symptomatic stage of this dysfunction. In view of this, it becomes necessary to provide early evaluation and treatment with physical therapy.

    Pain related to temporomandibular disorders (TMD) is a common problem in modern societies. The aim of the article is to present the concepts of TMD pain clinical management. A survey was performed using the PubMed, SCOPUS and CINAHL databases for documents published between 1994 and 2014. The following search keywords were selected using MeSH terms of the National Library of Medicine in combination: TMD pain, TMD, TMJ, TMJ disorders, occlusal splint, TMD physiotherapy, TMJ rheumatoid disorders and TMJ surgery. Original articles and review papers which presented the clinical relevance and practical validity regarding the possibility of application in TMD management have been included. Authors have excluded articles without outstanding practical aspect and evidence-based background. A first selection was carried out by reviewing titles and abstracts of all articles found according to the criteria. After that the full texts of potentially suitable articles were assessed. In line with these criteria, among 11467 results the writers have included 66 papers. The most commonly reported conservative treatments are massage therapy and individually fabricated occlusal splints. In addition to massage, other popular methods include manual therapy and taping, warming/cooling of aching joints, and light and laser therapy. Drugs are also commonly used. In the most severe cases of the temporomandibular joint degeneration, surgical restoration of the joint is sometimes applied. The authors concluded that conservative treatment including counselling, exercises, occlusal splint therapy, massage, manual therapy and others should be considered as a first choice therapy for TMD pain because of their low risk of side effects. In the case of severe acute pain or chronic pain resulting from serious disorders, inflammation and/or degeneration pharmacotherapy, minimally invasive and invasive procedures should be considered.

    To find out the best imaging parameters for the diagnosis of disc in MRI imaging. Compare the diagnostic quality of the disc among the T1, PD and T2 images of same patients (12 joints, 223 images) by visual (I-IV grades) and gray level measurement (pre- and infra-discal area) method. PD images showed best results with 43.7% of the images belonging to grade III (good) and with statistically significant higher difference of the gray levels at pre- and infra-discal areas. But there were no grade IV (excellent) images. PD images are best method among T1, PD and T2 images in diagnosing the disc but since there were no excellent images further imaging parameters should be studied for better images.

    Temporomandibular joint disorder (TMD) is a broad pain disorder that refers to several conditions affecting the temporomandibular joint of the jaw and the muscles of mastication. As with most pain disorders, a high prevalence of depression and anxiety is associated with TMD. Research has shown that selective serotonin reuptake inhibitors (SSRIs), the first-line drug therapy for major depressive disorder, may not be suitable for TMD patients because SSRIs can induce teeth-grinding, otherwise known as bruxism. This is problematic because bruxism is believed to further exacerbate TMD. Therefore, the purpose of this literature review is to better understand the mechanism of SSRI-induced bruxism, as well as discuss alternative antidepressant options for treating depression and anxiety in patients with bruxism and TMD. Alternative classes of antidepressants reviewed include serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, atypical antidepressants, and monoamine oxidase inhibitors. Findings indicate that dopamine agonists and buspirone are currently the most effective medications to treat the side effects of SSRI-induced bruxism, but results regarding the effectiveness of specific antidepressants that avoid bruxism altogether remain inconclusive.

    Full Text Available Congenital temporomandibular joint (TMJ ankylosis is an uncommon condition that presents itself at or soon after birth in the absence of acquired factors that could have contributed to the ankylosis such as infection and trauma. The experience of managing one such case is reported in light of a review of the literature on this condition. Key management principles include adequate removal of the ankylotic mass, costochondral grafting, and post-op physiotherapy. Most patients reported in the literature with the condition experienced relapse. This echoes our own experience where there was recurrence of the ankylosis. However, after removal of the ankylotic mass, the patient maintains a satisfactory maximal incisal opening (MIO till the present day. The additional challenges faced in the congenital form in addition to the already complex management of acquired paediatric temporomandibular joint ankylosis are (1 much earlier insult to the TMJ, (2 reduced opportunity for neuromuscular development of the muscles of mastication, and (3 reduced compliance with postoperative physiotherapy programmes due to the younger age of these patients.

We are reporting two cases of TMJ dislocation resulted from acute severe intoxication with pure propranolol (PPL for the first time. Bilateral TMJ dislocation happened in two patients who were admitted to intensive care unit with diagnosis of severe acute PPL toxicity. Clinical diagnosis of TMJ dislocation was obtained by physical examination. Successful reduction was performed for both patients without subsequent recurrence in two weeks following hospital discharge. Both of our subjects had no previous history of lower jaw dislocation. There was not any risk factor for dislocation such as convulsion during admission period, recent face trauma, or oral manipulation by the medical team. This study showed that TMJ dislocation may occur after severe acute PPL toxicity probably due to spastic contraction of the lateral pterygoid muscle. This is against previously mentioned hypothesis that stated masseteric muscles contraction as the main cause of a bilateral dislocated TMJ.Keywords: propranolol, toxicity, temporomandibular joint dislocation

    To investigate the relationship between omentin-1 levels and painful temporomandibular disorders (TMD). In a case-control design, chronic painful TMD cases (n = 90) and TMD-free controls (n = 54) were selected from participants in the multisite OPPERA study (Orofacial Pain: Prospective Evaluation and Risk Assessment). Painful TMD case status was determined by examination using established Research Diagnostic Criteria for TMD (RDC/TMD). Levels of omentin-1 in stored blood plasma samples were measured by using an enzyme linked immunosorbent assay. Binary logistic regression was used to calculate the odds ratios (ORs) and 95% confidence limits (CLs) for the association between omentin-1 and painful TMD. Models were adjusted for study site, age, sex, and body mass index. The unadjusted association between omentin-1 and chronic painful TMD was statistically nonsignificant (P = .072). Following adjustment for covariates, odds of TMD pain decreased 36% per standard deviation increase in circulating omentin-1 (adjusted OR = 0.64; 95% CL: 0.43, 0.96; P = .031). Circulating levels of omentin-1 were significantly lower in painful TMD cases than controls, suggesting that TMD pain is mediated by inflammatory pathways.

    Twenty-five postmeniscoplasty temporomandibular joints (TMJs) were studied in 20 patients. In all patients, preoperative MR images showed anteriorly dislocated disks. The patients underwent a similar postoperative MR examination 4-12 months after surgery. Surgical results were classified clinically as either poor, fair, good, or excellent at the time of the follow-up MR imaging. Forty percent of patients had good or excellent clinical results, and 60% had poor or fair results. The good/excellent group all had disks that appeared to be in normal or near normal position. Almost all disks were fixed in position. The degree of condylar translation was variable. The poor/fair group all had postoperative joints with anteriorly dislocated disks that were fixed in place. Recapture of the disk was variable, as was the degree of condylar translation

    To construct self-assembly fibrocartilage model of goat temporomandibular joint disc and observe the biological characteristics of the self-assembled fibrocartilage constructs, further to provide a basis for tissue engineering of the temporomandibular joint disc and other fibrocartilage. Cells from temporomandibular joint discs of goats were harvested and cultured. 5.5 x 10(6) cells were seeded in each agarose well with diameter 5 mm x depth 10 mm, daily replace of medium, cultured for 2 weeks. One day after seeding, goat temporomandibular joint disc cells in agarose wells were gathered and began to self-assemble into a disc-shaped base, then gradually turned into a round shape. When cultured for 2 weeks, hematoxylin-eosin staining was conducted and observed that cells were round and wrapped around by the matrix. Positive Safranin-O/fast green staining for glycosaminoglycans was observed throughout the entire constructs, and picro-sirius red staining was examined and distribution of numerous type I collagen was found. Immunohistochemistry staining demonstrated brown yellow particles in cytoplasm and around extracellular matrix, which showed self-assembly construct can produce type I collagen as native temporomandibular joint disc tissue. Production of extracellular matrix in self-assembly construct as native temporomandibular joint disc tissue indicates that the use of agarose wells to construct engineered temporomandibular joint disc will be possible and practicable.

    The temporomandibular joint(TMJ) is really a complex of two synovial space separated by fibrocartilaginous disc. Single inferior joint space arthrography is commonly performed for evaluation of TMJ disorders, which is known to be superior in demonstrating joint dynamics. But it reveals only the inferior surface of the disc. Therefore, dual space arthrography is superior to demonstrate the soft tissue anatomic feature of the joint such as disc position and shape. Authors performed 83 TMJ arthrograms in TMJ problems. Initially, the inferior joint space was done and then the superior space was sequentially contrasted. The follow results were noted: 1. In all cases, dual space arthrography revealed accurate disc shape and positions. 2. Concordant findings between the two techniques: 68 cases (82%). Discordance between the two techniques: 15 cases (18%) 3. Possible causes of discordance between inferior and dual space arthrography. a) Normal varians of anterior recess: 3 cases b) Posterior disc displacement: 4 cases c) Influence of the patient's head position change :4 cases d) False perforation: 2 cases e) Reduction change: 2 cases 4. In 5 cases with anterior displacement, dual space arthrography gave additional findings such as adhesion within the superior space, which could not be evaluated by single inferior space.

    The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint. Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created. After elaboration of the data through post-processing, the arterial supply of the temporomandibular joint was studied. The analysis revealed the superficial temporal artery, the anterior tympanic artery, the deep temporal artery, the auricular posterior artery, the transverse facial artery, the middle meningeal artery, and the maxillary artery with their branches as the main arterial sources for the lateral and medial temporomandibular joint. The direct volume rendering technique was found to be successful in the assessment of the arterial supply to the temporomandibular joint. The superficial temporal artery and maxillary artery ran along the lateral and medial sides of the condylar neck, suggesting that these arteries are at increased risk during soft-tissue procedures such as an elective arthroplasty of the temporomandibular joint.

    The sensory innervation of the temporomandibular joints (TMJs) of 8 STR/IN mice was investigated by means of light and electron microscopy. Through the cutting of complete semithin sections in series it was possible to investigate the joints thoroughly. Additionally, one joint with its nerve supply was reconstructed three-dimensionally with a computerized three-dimensional programme. The reconstruction was based on one complete semithin section series. The joint's nerve supply originates from the nervus auriculotemporalis and additionally from motor branches of the n. mandibularis: n. massetericus, n. pterygoideus lateralis and the nn. temporales posteriores. The greatest number of nerve fibres and endings is located in the dorsolateral part of the joint capsule. They lie only in the stratum fibrosum and subsynovially. Neither the stratum synoviale nor the discus articularis contain any nerve fibres or endings, whereas the peri-articular loose connective tissue is richly innervated. The only type of nerve ending observed within the joint was the free nerve ending, which is assumed to serve not only as a nociceptor but also as a polymodal mechanoreceptor. Merely within the insertion of the musculus pterygoideus lateralis at the collum mandibulae single stretch receptors of the Ruffini type were observed. Ultrastructurally, they correspond to those described in the cat's knee joint. Neither lamellated nor nerve endings of the Golgi or Pacini type were observed in the joint or in the peri-articular connective tissue. The unexpected paucity of nerve fibres and endings in the TMJ itself of the mouse suggests that the afferent information from the joint is less important for position sense and movement than the afferent information from muscles, tendons and periodontal ligaments.

    The purpose of this study was to determine the diagnostic value of high-resolution ultrasonography (US) in temporomandibular joint (TMJ) disc displacements. A number of 74 patients (148 TMJs) with signs and symptoms of TMJ disorders, according to the Research Diagnostic Criteria for Temporomandibular Disorders, were included in this study. All patients received US and magnetic resonance imaging (MRI) of both TMJs 1 to 5 days after the clinical examination. MRI examinations were performed using 1.5 T MRI equipment (Siemens Avanto, Siemens, Erlangen). Ultrasonographic examination was performed on a Hitachi EUB 8500 (Hitachi Medical Corp., Tokyo, Japan) scanner with L 54 M6.5-13 MHz linear transducer. MRI depicted 68 (45.95%) normal joints, 47 (31.76%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 34 (22.97%) with degenerative changes. US detected 78 (52.7%) normal joints, 37 (25%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 21 (14.19%) with degenerative changes. Compared to MRI, US showed a sensitivity of 93.1%, specificity of 87.88%, accuracy of 90.32%, a positive predictive value of 87.1% and a negative predictive value of 93.55% for overall diagnosis of disc displacement. The Youden index was 0.81. Based on our results, high-resolution ultrasonography showed high sensitivity, specificity and accuracy in the diagnosis of TMJ disc displacement. It could be a valuable imaging technique in assessing TMJ disc position. The diagnostic value of high-resolution ultrasonography depends strictly on the examiner's skills and on the equipment used.

    Since its introduction in the 1980s, magnetic resonance imaging has become the preferred method for diagnosing soft tissue abnormalities of temporomandibular joint (TMJ). MR imaging is non-invasive and more accurate than arthorography. In addition, it requires less operator skill and is well tolerated by patients. We are usually taking MR images of the TMJ with the fast spin echo technique that can simultaneously obtain both T2-weighted and proton density images. The purpose of this study was to determine the utility of T2-weighed and proton density images for diagnosing the disk status in TMJ, comparing the results with those obtained by T1-weighted images. We studied 104 TMJs in 52 patients with both T2-weighted and proton density images, and 80 TMJs in 40 patients with only T1-weighted images. The joints were evaluated by two oral radiologists who looked at three aspects of the joints-disk displacement, disk reduction and disk shape - giving ratings of good'' or ''fair'' in each category. Ratings of ''good'' were significant higher in all three categories in T2-weighted and proton density images than in T1-weighted images (p<0.01). Based on these results, we conclude that T2-weighted and proton density images taken with the fast spin echo technique are useful for diagnosing the disk status of the TMJ. (author)

    The Temporo-Mandibular Disorders (TMD) are a set of dysfunctional patterns concerning the temporo-mandibular joints (TMJ) and the masticatory muscles; its main symptom is pain, probably caused by inflammatory changes in the synovial membrane, alterations in the bone marrow of the mandibular condyle and impingement and compression. The aim of this preliminary study was to investigate the effectiveness in the TMD pain reduction of a new laser device recently proposed by the commerce that, due to its reduced dimensions and to be a class I laser according the ANSI classification, may be used at home by the patient himself. Twenty-four patients with TMD were randomly selected: the inclusion criteria for the sample was the diagnosis of mono- or bi-lateral TMD, with acute pain restricted to the joint area, associated with the absence of any muscle tenderness during palpation. The patients were randomly assigned to two groups: Group 1 (12 patients): patients receiving real LLLT (experimental group). Group 2 (12 patients): patients receiving inactive laser (placebo group). The treatment was performed once a day for two weeks with an 808 nm diode laser by the patient himself with irradiation of the cutaneous zone corresponding to the TMJ for 15 minutes each side. Each patient was instructed to express its pain in a visual analogue scale (VAS) making a perpendicular line between the two extremes representing the felt pain level.

    Although temporo-mandibular joint (TMJ) ankylosis is one of the most common pathologies afflicting the facial skeleton, it is also the most overlooked and under-managed problem in children. The TMJ forms the very cornerstone of cranio-facial integrity and hence its ankylosis in growing children adversely affects the growth and development of the jaws and occlusion. Impairment of speech, difficulty in mastication, poor oral hygiene, rampant caries and acute compromise of the airway pose a severe psychologic burden on the tender minds of children. The aim of this article is to present an overview of efficient management strategies, based on a case report, so as to increase its awareness among all dental surgeons involved in the treatment of children.

    Chronic dislocation of the temporo-mandibular joint (TMJ) is rare. It occurs when an acute dislocation is left untreated, in certain situations, including severe illness, neurologic or psychiatric diseases or prolonged oral intubation. A 79 years old woman, with Meige syndrome, suffered from bilateral dislocation of the TMJ for over 1 year. Surgical repositioning of the mandibular condyles and temporal bone eminectomy were performed. At the 18 postoperative months control, no recurrence has been noted. Treatment of chronic TMJ dislocations often requires a surgical procedure. Manual reduction, even under general anaesthesia, often fails because of severe muscular spasm and periarticular fibrotic changes. The management of this disorder is still controversial. We review available surgical procedures. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    A standardized CT procedure for examination of the temporomandibular joint (TMJ) with axial and coronal scanning as well as reformatted coronal and sagittal sections, was performed on 32 adults. These included subjects with normal TMJ and patients suffering from muscular dysfunction/disc displacement, arthrosis or rheumatoid arthritis. Some normal CT appearances simulating disease were presented. Axial CT scanning appeared to be the most useful method for demonstrating osseous abnormalities of the TMJ. The diagnostic information was occasionally supplemented by the coronal scanning, which may be difficult to perform on patients with neck stiffness. Reformatted coronal or sagittal sections mostly confirmed TMJ abnormality and supplemented the findings at axial scans in about one third of the patients. (orig.)

    Full Text Available Background: Ankylosis of the temporomandibular joint (TMJ is an intracapsular union of the disc-condyle complex to the temporal articular surface that restricts mandibular movements, including the fibrous adhesions or bony fusion between condyle, disc, glenoid fossa, and eminence. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and hygiene. Case Report: This report describes a case of a 12-year-old girl with inability to open her mouth, diagnosed with unilateral right bony TMJ ankylosis. The surgical approach consisted of gap arthroplasty with interpositional temporalis muscle flap followed by vigorous physiotherapy. Conclusion: The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence. Its treatment includes the orthodontist, oral and maxillofacial surgeon, pediatric dentist, and psychologist and physical therapist as part of the healthcare team.

    Disc displacement of the temporomandibular joint has been defined as an abnormal relationship between the articular disc and the mandibular condyle, fossa and articular eminence. Disc displacements may occur without immediate interference in the function of the joint. Magnetic resonance imaging shows high diagnostic accuracy in the determination of articular disc position and has been indicated as the diagnostic method of choice for soft tissue abnormalities of the temporomandibular joint. The aim of this study is to review the literature including the normal features and different types of disc displacement of the temporomandibular joint as well as the imaging findings, emphasizing the role of magnetic resonance imaging.

    This study reviewed the dental literature in order to determine the association of bone marrow edema with osteoarthritis and temporomandibular joint (TMJ) internal derangement disorders. A literature search was performed using electronic databases PubMed/Medline (National Library of Medicine, Bethesda, Maryland) and Cochrane for articles published during the last 15 years (January 2000-December 2014). A predetermined inclusion and exclusion criteria were used for filtering the scientific papers. Research articles fulfilling the basic inclusion criteria were included in the review. The reviewed studies showed that bone marrow edema is found in painful joints with osteoarthritis in a majority of cases. A few cases with no pain or significant degenerative changes are reported to have a bone marrow edema pattern as well. Bone marrow edema, increased fluid level, and pain are associated with osteoarthritis in the majority of patients reporting TMJ arthritis. Degenerative and disc displacement conditions are multifactorial and require further investigations. Magnetic resonance imaging can be employed to detect bone marrow edema even in the absence of pain and clinical symptoms in the patients of internal derangements.

    The author obtained the oblique lateral transcranial radiograms from 376 patients (114 of male, and 262 of female) with temporomandibular joint arthrosis. After tracing each film, the author analyzed the dimensional changes of the condylar heads with pain, clicking, mouth opening limitation, and masticatory difficulty respectively, which were the chief complaints of the TMJ arthrosis and compared these data with control group. The results were as follows; 1. There was a great predilection for occurrence of the TMJ arthrosis in female (262 cases) over male (114 cases). But there was no significant difference in ratio between the sexes on each symptom. In male, 60 patients (52.6%) had pain, 28 patients (24.6%) had clicking, 21 patients (18.4%) had mouth opening limitation, and 5 patients (4.4%) had masticatory difficulty. In female, 148 patients (56.5%) had pain, 57 patients (21.8%) had clicking, 47 patients (17.9%) had mouth opening limitation, and 10 patients (3.8%) had masticatory difficulty. 2.

    Full Text Available Background: The literature on total alloplastic temporomandibular joint (TMJ reconstructions is encouraging, and studies on total alloplastic TMJ replacements outcomes showed acceptable improvements in terms of both pain levels and jaw function. Nevertheless, some adverse events, such as heterotopic bone formation around the implanted prosthesis, may occur. In consideration of that, the present manuscript describes a case of heterotopic bone formation around a total temporomandibular joint prosthesis, which occurred several years after the implant. Methods: The present manuscript describes a case of heterotopic bone formation around a total TMJ prosthesis, which occurred several years after the implant in patients, who previously underwent multiple failed TMJ surgeries. Results: Ten years after the surgical TMJ replacement to solve an ankylotic bone block, the patient came to our attention again referring a progressive limitation in mouth opening. A computerized tomography showed evidence of marked heterotopic bone formation in the medial aspects of the joint, where a new-born ankylotic block occupied most part of the gap created by resecting the coronoid process at the time of the TMJ prosthesis insertion. Conclusions: Despite this adverse event has been sometimes described in the literature, this is the first case in which its occurrence happened several years after the temporomandibular joint replacement. It can be suggested that an accurate assessment of pre-operative risk factors for re-ankylosis (e.g., patients with multiple failed temporomandibular joint surgeries and within-intervention prevention (e.g., strategies to keep the bone interfaces around the implant separated should be better standardized and define in future studies.

    Full Text Available Abstract Background Glial cells have been shown to directly participate to the genesis and maintenance of chronic pain in both the sensory ganglia and the central nervous system (CNS. Indeed, glial cell activation has been reported in both the dorsal root ganglia and the spinal cord following injury or inflammation of the sciatic nerve, but no data are currently available in animal models of trigeminal sensitization. Therefore, in the present study, we evaluated glial cell activation in the trigeminal-spinal system following injection of the Complete Freund's Adjuvant (CFA into the temporomandibular joint, which generates inflammatory pain and trigeminal hypersensitivity. Results CFA-injected animals showed ipsilateral mechanical allodynia and temporomandibular joint edema, accompanied in the trigeminal ganglion by a strong increase in the number of GFAP-positive satellite glial cells encircling neurons and by the activation of resident macrophages. Seventy-two hours after CFA injection, activated microglial cells were observed in the ipsilateral trigeminal subnucleus caudalis and in the cervical dorsal horn, with a significant up-regulation of Iba1 immunoreactivity, but no signs of reactive astrogliosis were detected in the same areas. Since the purinergic system has been implicated in the activation of microglial cells during neuropathic pain, we have also evaluated the expression of the microglial-specific P2Y12 receptor subtype. No upregulation of this receptor was detected following induction of TMJ inflammation, suggesting that any possible role of P2Y12 in this paradigm of inflammatory pain does not involve changes in receptor expression. Conclusions Our data indicate that specific glial cell populations become activated in both the trigeminal ganglia and the CNS following induction of temporomandibular joint inflammation, and suggest that they might represent innovative targets for controlling pain during trigeminal nerve sensitization.

    Full Text Available Background. Temporomandibular joint (TMJ ankylosis is a union of the articular surface of the temporal bone to the disc-condyle complex that restricts mandibular movements due to either a fibrous or bony union between the head of the condyle and the glenoid fossa. Common etiological factors are trauma, infection, and pathology in the joint or systemic diseases. The diagnosis of TMJ ankylosis is established through physical and clinical evaluation, and imaging examination. Currently, the surgical techniques used to treat TMJ ankylosis are gap arthroplasty, interpositional arthroplasty, joint reconstruction, and distraction osteogenesis. Purpose. To provide overview about management of temporomandibular joint ankylosis with gap arthroplasty combined with physiotherapy post surgery. Case. A 12-year-old female patient came to Department of Oral and Maxillofacial Surgery with complaint of opening mouth restriction, which occured since one year prior to admission. After complete physical and radiographic examination, patient then was diagnosed with TMJ ankylosis due to neglected odontogenic infection. The treatment was performed with gap arthroplasty under general anesthesia. Patient then underwent physiotherapy after the surgery, including application of heat on the affected region and exercises to open and close mouth. Discussion. Ankylosis of TMJ is an uncommon case that results in chronic and severe limited mouth opening. The critical factor of successful treatment of TMJ ankylosis is early detection, correct surgery approach, implementation of an intensive physiotherapy program, and a good post-operative conduct. Therefore on this patient, gap arthroplasty was the chosen surgery approach followed by intensive physiotherapy. Conclusion.Management goal in TMJ ankylosis is  to increase the patient’s mandibular function, correct associated facial deformity, decrease pain, and prevent reankylosis. Careful surgical technique and subsequent atten

    The association between temporomandibular disorders (TMDs) and headaches, cervical spine dysfunction, and fibromyalgia is not artefactual. The aim of this review is to describe the comorbid relationship between TMD and these three major painful conditions and to discuss the clinical implications and the underlying pain mechanisms involved in these relationships. Common neuronal pathways and central sensitization processes are acknowledged as the main factors for the association between TMD and primary headaches, although the establishment of cause-effect mechanisms requires further clarification and characterization. The biomechanical aspects are not the main factors involved in the comorbid relationship between TMD and cervical spine dysfunction, which can be better explained by the neuronal convergence of the trigeminal and cervical spine sensory pathways as well as by central sensitization processes. The association between TMD and fibromyalgia also has supporting evidence in the literature, and the proposed main mechanism underlying this relationship is the impairment of the descending pain inhibitory system. In this particular scenario, a cause-effect relationship is more likely to occur in one direction, that is, fibromyalgia as a risk factor for TMD. Therefore, clinical awareness of the association between TMD and painful comorbidities and the support of multidisciplinary approaches are required to recognize these related conditions.

    TMJ osteoarthrosis and internal derangements are in close connection, representing a substantial portion of temporomandibular disorders. The authors wish to underline the role of surgery in the treatment of this degenerative disease to improve function and to alleviate pain. A 63 year-old woman suffering from closed-lock with reduced opening movements was accepted in our Department in March, 1995. Clinical and radiological evaluations showed bilateral closed lock and severe TMJ osteoarthrosis. Occlusal, pharmacological and physical therapy were performed for one year, without results. Bilateral condylectomy and diskectomy with arthroplasty were carried out. Immediate muscular rehabilitation after surgery was performed by the patient. Follow-up 3, 6, 12 months after surgery were carried out. Full opening movements and reduction of pain were obtained 20 days after surgery. The patient, followed-up one year after surgery, presented effective mandibular movements and adequate amelioration of clinical picture. TMJ surgery in association with physical therapy represents in selected cases an adequate procedure for the treatment of TMJ degenerative disease.

    Findings in 31 pediatric patients with pain and dysfunction of the temporomandibular joint (TMJ) are reported. The average age was 14 years and the average duration of symptoms was 21.4 months. Internal derangements were found in 29 patients (94%) and degenerative arthritis in 13 (42%). In 12 patients (39%), the problem could be traced to an injury to the jaw. Secondary condylar hypoplasia was associated with the meniscal abnormality in 3 patients (10%). Further awareness of internal derangements of the TMJ in the pediatric population should permit greater recognition of their etiology. It is important that threatment be initiated as soon as possible, not only to minimize the development of osseous disease in young adults but also to prevent facial growth deformities

    Bony fusion between the mandibular condyle and skull base involves temporomandibular joint (TMJ) bony ankylosis. This condition might originate from trauma, infection, or systemic disease. TMJ adhesion can develop after synovial damage. Both TMJ ankylosis and adhesion lead to functional impairment and pain. Here, we present a case of a 50-year-old female who had bony ankylosis of the right TMJ and adhesion of the left TMJ. She had otitis media in the right ear. A large mass in the right TMJ was observed on computed tomograph. Magnetic resonance image showed a large fused bone mass with normal bone marrow in the right TMJ and flattening of the condyle with a thin disk in the left TMJ. Gap arthroplasty with temporal fascia was performed on the right TMJ, and discectomy, high condylectomy, and coronoidectomy were performed on the left TMJ. During a 2-year follow-up after surgery, the patient had no recurrence

    Temporomandibular joint (TMJ) arthroscopy is a minimally invasive surgical approach for intra-articular TMJ diseases. Office-based arthroscopy using the smallest TMJ scope allows for good visualization, as well as the ability to lavage the joint in an office setting. This study aimed to assess the efficacy of an office-based TMJ arthroscopic technique. A retrospective evaluation of 363 patients with a TMJ disorder was performed. These patients underwent office-based arthroscopy using the OnPoint 1.2mm Scope System (Biomet Microfixation, Jacksonville, FL, USA) in Florida, USA, from July 2007. The following outcomes of the procedure were assessed: improvement in painless range of mandibular motion, pain on loading, and functional jaw pain; these were evaluated using a visual analog scale (VAS) over an average follow-up period of 263.81±142.1 days. The statistical analysis was performed using IBM SPSS Statistics version 20. Statistically significant improvements in TMJ pain and function, and other variables (P=0.001) were shown following TMJ arthroscopic lysis and lavage. Office-based arthroscopy using the OnPoint System was demonstrated to be a safe and efficient procedure for the treatment of patients with TMJ disorders as the first level of the algorithm of care.

    The aim of this study was to compare and evaluate the efficacy of different concentrations of dextrose prolotherapy for the treatment of temporomandibular joint (TMJ) hypermobility. A prospective, randomized clinical trial including patients with subluxation or dislocation was performed. The study comprised 40 patients. Patients were randomly divided into 4 groups: control group, 10% dextrose, 20% dextrose, and 30% dextrose group. Patients in all groups received injections into 4 different areas of each TMJ in 4 sessions at monthly intervals. Visual analog scale of TMJ pain intensity, maximum mouth opening (MMO), joint sounds, and frequency of luxations were recorded preoperatively and postoperatively after 1 month of last injection. The collected data were then statistically analyzed. Each group showed postoperatively significant improvement in TMJ pain, significant decrease in both MMO and joint sound. Besides that, TMJ locking was not observed in any patient during the follow-up period. There were no statistically significant differences throughout the study intervals between the groups. It was concluded that there was no significant difference between control group and dextrose groups and there is no superiority of any concentration of dextrose over the others in TMJ prolotherapy, and all treatment procedures were efficient in improvement of clinical symptoms related to TMJ hypermobility. If dextrose is used as a proliferant, it can be said that 10% dextrose can be sufficient in TMJ hypermobility treatment.

    To evaluate the clinical effect of joint reconstruction by using autogenous coronoid process graft to treat temporomandibular joint(TMJ) ankylosis. Nine cases of TMJ ankylosis from September 2008 to September 2010 were surgically treated by joint reconstruction with autogenous coronoid process graft, using autogenous articular disc or prosthodontic membrane as interpositional material. Mouth opening, occlusion and cone beam CT(CBCT) were used for evaluation before and after surgery. Satisfactory mouth opening was achieved in all patients and no one got occlusal changes or reankylosis during follow-up. CBCT showed that coronoid process graft reached bone union with the ramus and turned to be round. It is effective to cure TMJ ankylosis through joint reconstruction with autogenous coronoid process graft.

    Full Text Available Background and aims. Trauma is one of the major factors associated with temporomandibular joint disorders (TMD. These disorders result from macro-trauma or micro-trauma. Macro-trauma might be iatrogenic; for example, from intubation procedures, third molar extraction procedures, and lengthy dental appointments. The aim of this study was to evaluate the effect of lengthy root canal therapy (more than 2 hours on TMJ and its supporting structures. Materials and methods. Eighty patients whose root canal therapy session lasted more than 2 hours were examined for the status of TMJ and masticatory muscles. After one week the second part of the examination was carried out for TMJ problems and pain and tenderness levels of masticatory muscles. Data was analyzed using Wilcoxon statistical test. Results. Women showed more pain compared to men. There was a significant increase in pain in the external acoustic meatus examination one week after root canal therapy. Patients who were treated for their posterior teeth suffered more pain than those who were treated for the anteriors and premolars. Other aspects of the examination were not affected significantly by lengthy root canal therapy. Conclusion. Lengthy dental treatments can harm TMJ and masticatory muscles and wide opening of the mouth during such appointments can worsen the situation. Therefore, it is wise to break the appointment into shorter intervals and let the patients rest during treatment to close their mouth to prevent iatrogenic damage to TMJ.

Los queratoquistes odontógenos que se agrupan para su estudio dentro de los quistes odontogénicos del desarrollo, representan cerca del 7 al 10 por ciento de todos los quistes maxilo-mandibulares. Se dice que tienen dos picos de incidencia entre la segunda y tercera década de vida y entre los 50 y 60 años de edad, con una ligera predilección por el sexo masculino. Aparece más frecuentemente en la región del tercer molar de la mandíbula con extensión a la rama ascendente El presente trabajo tuvo como objetivo mostrar el caso de un paciente masculino de 57 años de edad en el que fue necesario el reemplazo articular temporomandibular debido a un queratoquiste odontogénico que involucraba la totalidad de la rama mandibular derecha, incluyendo el proceso condíleo y coronoideo, así como el ángulo hasta el tercio posterior del cuerpo mandibular.

Among the most frequent are ankylosis, osteoarthrosis, advanced stages of the temporomandibular dysfunction syndrome, post-traumatic joint damage, and neoplastic or tumoral processes. Odontogenic keratocysts, which are classified as developmental odontogenic cysts for study purposes, constitute 7-10 per cent of all maxillomandibular cysts. Two peaks have been identified in their incidence: between the second and third decades of life, and between 50 and 60 years of age, with a slight predominance of the male sex. They are most common in the third molar area of the mandibule, with expansion to the ascending branch. A case is

    Aim and objectives. The morphology and position of the temporo-mandibular disc are key issues in the diagnosis and treatment of arthrogenous temporo-mandibular disorders. Magnetic resonance imaging and arthroscopy are used today to identify: flattening of the pars posterior of the disc, perforation and/or adhesions in the pars intermedia of the disc and disc displacements. The present study proposes the investigation of the temporo-mandibular joint disc by optical coherence tomography (OCT). Material and methods. 8 human temporo-mandibular joint discs were harvested from dead subjects, under 40 year of age, and conserved in formalin. They had a normal morphology, with a thicker pars posterior (2,6 mm on the average) and a thinner pars intermedia (1mm on the average). We investigated the disc samples using two different OCT systems: an en-face OCT (time domain (TD)-OCT) system, working at 1300 nm (C-scan and B-scan mode) and a spectral OCT system (a Fourier domain (FD)-OCT) system , working at 840 nm (B-scan mode). Results. The OCT investigation of the temporo-mandibular joint discs revealed a homogeneous microstructure. The longer wavelength of the TD-OCT offers a higher penetration depth (2,5 mm in air), which is important for the analysis of the pars posterior, while the FD-OCT is much faster. Conclusions: OCT is a promising imaging method for the microstructural characterization of the temporo-mandibular disc.

    Laterality of function in the orofacial musculature suggests there may be side-to-side asymmetry of proprioceptive acuity in lip movement compared to the temporomandibular joint (TMJ). In the present work, 14 young adults were tested for acuity of lip and TMJ closure movements onto plugs varying from 5 to 8mm without visual feedback. Testing was conducted on both left and right sides, using the same psychophysical task and stimuli. Results showed superior proprioceptive acuity at the lips, with no significant side effect. However, there was side-to-side asymmetry in the correlations between proprioceptive performance for the two anatomical structures, with performance on the right side strongly correlated but not on the left. This is consistent with the need for coordination between structures during chewing. When acuity at different points in the stimulus range was examined, the right side lips were better with small stimuli. Overall, results support enhanced use-specific proprioception.

    2015-06-01

    This article reviews the pathophysiology of scleroderma (systemic sclerosis [SSc]) and its destructive effects on the mandible in general and the temporomandibular joint (TMJ) in particular. It discusses the considerations of operating on patients with devastating chronic disease and presents 2 cases of TMJ reconstruction in patients with the diagnosis. Two patients with different degrees of SSc involvement underwent TMJ reconstruction with costochondral grafts. The patients represent the surgical considerations pertinent to this disease and different outcomes as determined by the variance in severity of their afflictions. The 2 patients tolerated the surgeries well and exhibited improvement in function in the long-term. One patient thrives and continues to do well despite her SSc approximately 10 years postoperatively; the second patient died of her disease approximately 9 years after her initial surgical care. The experience with these 2 cases showed that patients with SSc can safely undergo TMJ reconstruction with anticipated good results, but that the overall severity of the disease remains paramount in determining the feasibility of corrective surgery under this diagnosis.

    To analyze the possible association between magnetic resonance imaging signal intensity of temporomandibular joint disk and posterior attachment, and the type and extent of disk displacement, disk donfiguration, effusion and clinical signs in patients with internal derangement. Magnetic resonance images of the 132 temporomandibular joints of 66 patients with temporomandibular joint displacement were analyzed. The clinical findings were obtained by retrospective review of the patients' records. The type and extent of disk displacement, disk configuration and effusion were evaluated on the proton density MR images. The signal intensity from the anterior band, posterior band and posterior attachment were measured on MR images. The associations between the type and extent of disk displacement, disk configuration, effusion and clinical signs and the MR signal intensity of disk and posterior attachment were statistically analyzed by student's t-test. Of 132 joints, 87 (65.9%) showed anterior disk displacement with reduction (ADR) and 45 (34.1%) showed anterior disk displacement without reduction (ADnR). This signals from posterior attachments were lower in joints with ADnR than those of ADR (p<0.05). The results showed statistically significant (p<0.05) association between the type and extent of disk displacement and disk configuration, and decreased signal intensity of posterior attachment. There were no statistical associations between pain, noise and limited mouth opening, and signal intensity of disk and posterior attachment. The average signal from posterior attachment was lower in joints with ADnR than that of ADR. The type and extent of disk displacement and disk configuration appeared to be correlated with the signal intensity from posterior attachment

    Objective: : The purpose of this study is to determine the prevalence of radiographic presence of otomastoiditis while examining temporomandibular joint (TMJ) disorders in magnetic resonance images (MRI) in a series of 2270 temporomandibular joint magnetic resonance images and to examine the relationship between otomastoiditis and TMJ disorders. Materials and methods: : 2270 temporomandibular joint magnetic resonance images and patients' data were retrospectively investigated. Magnetic resonance images were obtained from the patients who referred to Osaka University Dental Hospital Outpatient Clinic with TMJ complaints for the last four years (from January 1998 to January 2003). The patients, who were diagnosed as otomastoiditis based on their temporomandibular joint magnetic resonance images, were sent to Osaka University Hospital Department of Otolaryngology for a medical consultation in order to have their pathologies certified following their MR process. Age and sex were recorded for all patients and for otomastoiditis cases; location of the disease, symptoms of patients and TMJ findings were noted as well. Results: : Seven patients were diagnosed as acute otomastoiditis and one patient diagnosed as chronic active otitis media with cholesteatoma in the series of 2270 MR, which were representing a prevalence of 0.39%. Neurilemoma diagnosed in left mastoid process in one patient. The final diagnoses of all patients were made after medical consultation. Conclusion: : While examining temporomandibular joint magnetic resonance images; it is not only important to examine just the TMJ structures, but also to look at the nearby anatomical features to check evidence for inflammatory disease.

    Objective: : The purpose of this study is to determine the prevalence of radiographic presence of otomastoiditis while examining temporomandibular joint (TMJ) disorders in magnetic resonance images (MRI) in a series of 2270 temporomandibular joint magnetic resonance images and to examine the relationship between otomastoiditis and TMJ disorders. Materials and methods: : 2270 temporomandibular joint magnetic resonance images and patients' data were retrospectively investigated. Magnetic resonance images were obtained from the patients who referred to Osaka University Dental Hospital Outpatient Clinic with TMJ complaints for the last four years (from January 1998 to January 2003). The patients, who were diagnosed as otomastoiditis based on their temporomandibular joint magnetic resonance images, were sent to Osaka University Hospital Department of Otolaryngology for a medical consultation in order to have their pathologies certified following their MR process. Age and sex were recorded for all patients and for otomastoiditis cases; location of the disease, symptoms of patients and TMJ findings were noted as well. Results: : Seven patients were diagnosed as acute otomastoiditis and one patient diagnosed as chronic active otitis media with cholesteatoma in the series of 2270 MR, which were representing a prevalence of 0.39%. Neurilemoma diagnosed in left mastoid process in one patient. The final diagnoses of all patients were made after medical consultation. Conclusion: : While examining temporomandibular joint magnetic resonance images; it is not only important to examine just the TMJ structures, but also to look at the nearby anatomical features to check evidence for inflammatory disease

    Full Text Available Ear acupuncture works by reducing painful sensations with analgesic effect through microsystem therapy and has been demonstrated to be as effective as conventional therapies in the control of facial pain. This clinical trial aimed to evaluate the adjuvant action of auricular acupuncture through an observation of the evolution of temporomandibular and masticatory myofascial symptoms in two groups defined by the therapies elected: auricular acupuncture associated with occlusal splint (study and the use of the occlusal splint plate alone (control. We have selected 20 patients, who were randomly allocated into two groups of ten individuals. Symptoms were evaluated in five different moments, every seven days. We analyzed the orofacial muscle and joint palpation in order to measure the intensity of the experienced pain. Both groups showed a statistically significant decrease in muscle and joint symptoms (p<0.05. However, comparisons between the groups showed an expressive and significant reduction of symptomatology in the study group (p<0.05 already on the first week of therapy. According to the results, to the methodological criteria developed and statistical analysis applied, the conclusion is that auricular acupuncture therapy has synergistic action on conventional occlusal splint treatment. It was demonstrated to be effective in the reduction of symptoms in the short term.

    Full Text Available Purpose. We evaluated the efficacy of arthrocentesis in the treatment of temporomandibular joint (TMJ disorders. Material and Methods. In this prospective clinical case series, 30 consecutive patients with TMJ disorders underwent arthrocentesis using saline and sodium hyaluronate injections. Outcome measures were TMJ pain, maximum mouth opening (MMO, joint noises, and anatomical changes in the TMJ architecture. Patients were evaluated using cone-beam computed tomography (CBCT and magnetic resonance imaging (MRI at the beginning of treatment and 60 days after the last arthrocentesis. Pretreatment and posttreatment clinical parameters were compared using paired and unpaired t-tests, and McNemar’s test was used to evaluate CBCT and MRI changes (. Results. At 1-year follow-up examinations, visual analogue scale scores indicated that pain was reduced significantly and mean postoperative MMO was increased significantly. CBCT findings showed no significant change, and MRI showed only slight reductions in inflammatory signs. Conclusions. Within the limitations of this study, we can conclude that arthrocentesis is a simple, minimally invasive procedure with a relatively low risk of complications and significant clinical benefits in patients with TMJ disorders. This trial is registered with NCT01903512.

    Although an interaction of malocclusion, parafunction, and temporomandibular joint disorders (TMD) can be inferred from the experience of daily practice, scientific evidence to corroborate this hypothesis does not exist. However, there are indications that TMD and headaches may be intertwined. The purpose of this study was to identify the presence or absence of an association of occlusal interferences, parafunction, TMD, or physiologic, muscular, or prosthodontic factors with the occurrence of headache. In a private practice population of 1031 subjects (436 men and 595 women, mean age 49.6 years) the demographic parameters, headache and general pain history, habits and general personal information were recorded. Clinical examination for dental, muscular, and temporomandibular joint pathology was accomplished. Data were statistically analyzed using the Mann-Whitney U, Kruskal-Wallis, and Chi-Square tests (α = .05). A multinomial logistic regression analysis was performed with respect to confounding variables. Headache affliction was found to affect women more frequently than men (1.7:1). Students and non academics were more prone to suffer from headache. Parafunction (P=.001), TMD (P=.001) and gross differences between centric occlusion and maximum intercuspation of more than a 3 mm visible track marked with 8 μm articulation foil (P=.001) significantly influenced the presence of headache. Headache intensity and frequency decreased with age. While tension-type headache was most frequently diagnosed, the parameters studied were not significantly associated with one certain headache diagnosis more frequently than others. Stomatognathic factors of TMD, parafunction, and gross differences between centric occlusion and maximum intercuspation of more than 3 mm are associated with headache. These findings should be interpreted with caution due to the cross-sectional nature of this study. Copyright © 2011 The Editorial Council of the Journal of Prosthetic Dentistry

    Full Text Available Los pacientes con deformidades craneofaciales requieren generalmente multiples y, a veces, complejos procedimientos quirurgicos para reconstruir tejidos blandos y duros alterados. Un avance importante en cirugía reconstructiva es el alargamiento de la mandibula por distracción que tiene la ventaja de una cirugía menos agresiva que determinados tipos de osteotomías. Con esta técnica una osteotomía bicortical se hace en distintas zonas de la mandibula colocandose el distractor hasta alcanzar los efectos deseados. Aunque las fuerzas aplicadas se han mostrado eficaces para alargar la mandíbula, sus efectos en segmentos proximales y distales, incluyendo la articulación temporomandibular no han sido analizados sistemáticamente. En este artículo se repasa trabajos experimentales y clínicos en los que se detalla la relación entre distracción mandibular y articulación temporomandibular.Abstract: Patients with severe craniofacial abnormalities often require multiple and complex surgical procedures to reconstruct maldeveloped hard and soft tissues of the maxillofacial complex. An important advance in reconstructive surgery is mandibular lengthening by gradual distraction, which takes advantage to be less agressive surgery than some osteotomies. With this technique, a bicortical osteotomy is made at the angle of the deficient mandible, and an expansion appliance is placed across the osteotomy line. Although the applied forces have been shown to lengthen the mandible effectively in the region of the application, their effects on the proximal and distal mandibular segments, including the temporomandibular joint region, have not been analyzed systematically. In this article, we study several experimental and clinical papers where it describes the relationship between mandibular distraction and temporomandibular joint.

    Evidence on cultural differences in prevalence and impact of common chronic pain conditions, comparing individuals with temporomandibular disorders (TMD) versus individuals without TMD, is limited. The aim was to assess cross-cultural comorbid pain conditions in women with chronic TMD pain. Consecutive women patients (n = 122) with the index condition of chronic TMD pain diagnosed per the research diagnostic criteria for TMD and TMD-free controls (n = 121) matched for age were recruited in Saudi Arabia, Italy and Sweden. Self-report questionnaires assessed back, chest, stomach and head pain for prevalence, pain intensity and interference with daily activities. Logistic regression was used for binary variables, and ancova was used for parametric data analysis, adjusting for age and education. Back pain was the only comorbid condition with a different prevalence across cultures; Swedes reported a lower prevalence compared to Saudis (P 50% due to back pain compared to Italians or Swedes (P cultures. The total number of comorbid conditions did not differ cross-culturally but were reported more by TMD-pain cases than TMD-free controls (P Culture influences the associated comorbidity of common pain conditions.

    The optimal reconstruction of the mandible and of the temporo-mandibular joint after mandibular hemi-resection with disarticulation is still controversial in literature. This paperwork presents our experience on four cases in the reconstruction of the mandible together with the inferior arthroplasty of the temporo-mandibular joint, after the resection of extended benign tumors of the mandible, based on fibular free vascularized grafts having attached a Stryker titanium condylar prosthesis reconstructing the inferior segment of the temporo-mandibular joint. Our results for the this technique were excellent, with a functional rehabilitation very close to normal. After reviewing the various techniques and their arguments in literature, with accent on the TMJ reconstruction, we consider this method to be optimal for the reconstruction of mandibular defects in patients with neoplastic conditions.

    2015-09-01

    Full Text Available The study describes a rare clinical case of synovial chondromatosis of the temporo-mandibular joint, in a 53 year-old patient. In the prehospital stage, the patient was examined by additional diagnostic methods – 3D CT and subsequent computer simulation, in view of subsequent surgery. In January 2015, partial synovektomy of the right temporo-mandibular joint with removal of cartilaginous impurities was performed under general anesthesia. After histopathological confirmation of the clinical diagnosis, the patient was discharged in satisfactory condition, with recommendations for further examination and radiological control. Synovial chondromatosis of the temporo-mandibular joint is a disease characterized by impaired formation of cartilage or of intraarticular, cartilaginous, and relatively rare bone impurities. An important role in the diagnosis of joints’ synovial chondromatosis is played by the instrumental research methods, especially X-ray. Surgical treatment is recommended as a function of the prevalence of lesions.

    In human medicine, magnetic resonance imaging (MRI) is considered the 'gold standard' imaging procedure to assess the temporomandibular joint (TMJ). However, there is no information regarding MRI evaluation of equine TMJ. To describe the normal sectional MRI anatomy of equine TMJ by using frozen and plastinated anatomical sections as reference; and determine the best imaging planes and sequences to visualise TMJ components. TMJs from 6 Spanish Purebred horse cadavers (4 immature and 2 mature) underwent MRI examination. Spin-echo T1-weighting (SE T1W), T2*W, fat-suppressed (FS) proton density-weighting (PDW) and fast spin-echo T2-weighting (FSE T2W) sequences were obtained in oblique sagittal, transverse and dorsal planes. Anatomical sections were procured on the same planes for a thorough interpretation. The oblique sagittal and transverse planes were the most informative anatomical planes. SE T1W images showed excellent spatial resolution and resulted in superior anatomic detail when comparing to other sequences. FSE T2W sequence provided an acceptable anatomical depiction but T2*W and fat-suppressed PDW demonstrated higher contrast in visualisation of the disc, synovial fluid, synovial pouches and articular cartilage. The SE T1W sequence in oblique sagittal and transverse plane should be the baseline to identify anatomy. The T2*W and fat-suppressed PDW sequences enhance the study of the articular cartilage and synovial pouches better than FSE T2W. The information provided in this paper should aid clinicians in the interpretation of MRI images of equine TMJ and assist in the early diagnosis of those problems that could not be diagnosed by other means.

    Recurrent pains of the temporomandibular joint represent a frequent symptom with numerous different causes. CT and MRI can reliably show the cause of these disorders and therefore have substituted conventional X-ray imaging. Modern multi-slice-CT (MSCT) allows for examination of the skull base including the mandible in a very short time with thinnest slice collimation (0.75 mm). With 2D- and 3D- reformations reconstructed out of this volume data set in parasagittal, coronal or any other arbitrary slice orientation excellent imaging of fractures and bony changes of arthrosis as well as benign and malignant tumors of the temporomandibular joint can be performed. MRI offers very good soft tissue contrast in order to visualize the intra-articular disc, the ligaments and muscles, as well the possibility to acquire cross sectional images in any user-defined orientation. MRI is the method of choice to diagnose 'internal derangement', particularly displacement of the intra-articular disc and inflammatory disease of the temporomandibular joint. The present paper will provide diagnostic strategies for the use of MSCT or MRI imaging concerning the different causes of disorders to the temporomandibular joint. (orig.)

    One hundred temporo-mandibular joints were examined with a super-conducting nuclear resonance tomograph (1.0 Tesla) using various high resolution surface coils. The optimal method proved to be a spin echo sequence with a repetition time of 1,000 msec and an echo period of 28 msec with a 4 mm slice width. There were significant advantages from the non-invasive MRT diagnosis of the temporo-mandibular joints when compared with CT and with arthrography in recognising abnormal discs, changes in the tissues and for post-operative control.

    The Acromegaly is an endocrinological disease determined by the hypersecretion of STH in a certain period of the body evolution and it causes the hypertrophy of bones in general and of mandible and cranio-facial bones, determining a disorder due to this development of bones, associated with troubles in the activity of muscles and of the phospho-calcium metabolism. This study was made on a group of 33 acromegaly patients. Their temporo-mandibular joint was investigated by ortopantomography, tomography, computer tomography and scintigraphy. All of these exams shows the changes in temporo-mandibular joint due to the cells hyperactivity determined by the hypersecretion of STH.

    This report is a retrospective study of fluid extravasation as a complication of temporomandibular joint pumping and perfusion. Contrast-enhanced 3D-CT of the upper joint compartment was performed for presurgical diagnosis before temporomandibular joint arthroscopic surgery in our hospital from 1996 to 2000. From these cases, 43 joints and 38 patients were selected because they had not improved under conservative treatment during the previous six months. Fluid extravasation of the articular capsule was recognized in 9 joints (20.9%) in 9 patients, 3 males and 6 females. Two of the nine patients had undergone arthroscopic observation before surgery. This test had revealed only thin articular capsule, not a perforation, in any of these cases. The data indicate only extremely tiny perforations or infiltration leakage due to the fluid pressure in the upper joint compartment during pumping or perfusion. Oral and maxillofacial surgeons should be aware of this complication. (author)

    Headache is a common symptom, that can be extremely disabling, affecting 26 million of patients only in Italy. ICHD-II has reported two categories: "primary headaches" and "secondary headaches". Temporomandibular joint disorders can lead to a secondary headaches. We want to evaluate the prevalence and clinical features of headache among a series of patients having temporomandibular joint disorders and we illustrate the evolution of headache following medical treatament of temporomandibular joint (TMJ) disorders. This is a retrospective study carried out on chart review of 426 consecutive patients with various degrees of temporomandibular disorders and treated with medical devices from 2007 to 2011. Headache was reported by 73 patients (17.14%). Headache was observed in 36 of 51 patients with lock and in 32 out of 130 patients with mandibular deflections (Table I). The remaining 5 patients with headache had articular noise. Headache is not a rare finding in a population with temporomandibular dysfunctions and is more often a tension-type rather than trigeminal headache.

    The aim of this study was to investigate dentist's approaches to the use of splint therapy for myofascial pain, bruxism, and temporomandibular joint (TMJ) disorders and to assessment of treatment modalities. A 12-item questionnaire was developed to determine dentists' knowledge of TMJ disorders and approaches for occlusal splint treatments. The researchers spoke with each dentist included in the study at his/her clinic or by telephone to assess their immediate knowledge and approach to the TMJ disorders. Chi-squared test was performed to analyze the values. The confidence interval was set as 95%. A total of 370 dentists working in Turkey were participated in this study. The most common splint application reason for occlusal splint treatment was bruxism (77.8%) while TMJ pain was very rare (%1.4). The use of hard splint ratios for 0-5 years of professional experience was 57.0%, 42.4.0%, and 26.8% for the experience of 5-15 years and over 15 years groups, respectively (P < 0.001). While the dentists' with sufficient knowledge soft splint application rates were 11.6%, hard splint application rates were 43.4% for the dentists with sufficient knowledge. Occlusion adjustment rate of dentists who practice in all three groups was under 16.0%. The knowledge of the dentists about TMJ disorders and occlusal splint therapy were found to be insufficient. Their knowledge decreased with increasing experience.

    Full Text Available Temporomandibular disorders (TMD are clinical conditions characterized by pain and sounds of the temporomandibular joint (TMJ. This study was designed to assess the effect of low-level laser therapy (LLLT on healing of osteoarthritis in rats with TMD.Thirty-two male Wistar rats (250-200 g were housed in standard plastic cages. After injection of Complete Freund's adjuvant into the TMJ, rats were randomly divided into two groups of 16 (case and control and anesthetized; then osteoarthritis was induced via intraarticular injection of 50 µl of Complete Freund's adjuvant; into the bilateral TMJs. In the case group, LLLT was done transcutaneously for 10 minutes daily, starting the day after the confirmation of osteoarthritis. Exposure was performed for 10 minutes at the right side of the TMJ with 880 nm low-level laser with 100 mW power and a probe diameter of 0.8 mm. Control rats were not treated with laser.After three days of treatment the grade of cartilage defects, number of inflammatory cells, angiogenesis, number of cell layers and arthritis in rats in the case group were not significantly different compared with controls (P>0.05. After seven days, the grade of cartilage defects, number of inflammatory cells, number of cell layers, and arthritis in the case group improved compared to controls (P<0.05; angiogenesis in both groups was similar.Treatment of TMD with LLLT after 7 days of irradiation with a wavelength of 880 nm was associated with a greater improvement compared to the control group.

    Full Text Available Osteoarthrosis (OA of temporomandibular joint (TMJ is a progressive degenerative disease, gradually affecting cartilage, synovial membrane and bone structures. OA of TMJ clinically manifests with joint noises, pain and restricted mouth opening. In late stages, it results in severe damage of TMJ structures and development of ankylosis. Osteoarthrosis is a multifactorial disease; the occurrence is associated with TMJ overloading. The cohort included 619 patients [538 women (87% and 81 men (13%, with average age 40.6 years (age range 8–89 years] with TMJ disorder, who were examined in the year 2014 in Department of Dental Medicine, First Faculty of Medicine, Charles University and General University Hospital in Prague, Czech Republic. The aim of this retrospective study was to analyse, if the lack of posterior teeth (supporting teeth zones is the main etiologic factor of osteoarthrosis of TMJ. Diagnosis of OA was established on the clinical signs and the panoramic X-ray signs. Simultaneously other etiologic factors of OA were assessed. The presence of OA changes on X-ray had 171 patients (i.e. 27.6% of the total number of 619. 17.5% from these patients with OA had defect in posterior dentition. Other aetiological factors (stress, skeletal or vertebrogenous disorders showed higher incidence of OA changes on X-ray. Defect of posterior dentition is not negligible, but it is not the main aetiological factor for osteoarthrosis of TMJ.

    Since publication of the UK guidelines on total replacement of the temporomandibular joint (TMJ) in 2008 by the British Association of Oral and Maxillofacial Surgeons (BAOMS), pain scores, mouth opening, and diet have been used as markers of success. We have looked at quality of life (QoL) as another. We analysed the data from a single surgeon on patients who had had joints replaced and devised a questionnaire to find out about the subjective, functional, psychological, and social aspects of TMJ disease. A total of 18 patients who had the same operation were included (mean (range) age 50 (33 - 73) years, mean (range) follow up 30 (18 - 48) months). Jaw function and facial aesthetics had improved, and patients needed less analgesia. Overall, they reported a better QoL with improvements in mood and social interaction, and the activities of daily life were easier. The NHS uses QoL questionnaires to measure success in fields such as orthopaedic surgery, but currently we know of no nationally accepted questionnaire that measures success after total replacement of the TMJ.

    2005-01-01

    This study was designed to evaluate the suggestion that the clinical findings and MR image findings of anterior disc displacement with reduction cases could not reduce the disc displacement within the follow-up period. We selected 26 joints without remarkable bone changes in the condylar head or glenoid fossa in which reduction disappeared during follow-up. Clinical evaluation focused on temporomandibular pain, trismus, and joint sound. MR imaging was targeted for configuration of articular disc, degree of disc displacement, and condylar head position. Clinical signs observed with progression of the condition were disappearance of joint sound in 12/26 joints (46.1%), temporomandibular pain in 15/26 joints (57.6%), and decreased distance of opening mouth in 19/26 joints (73%). MR image findings were disc configuration changes in 12/26 joints (46.1%), increased degree of anterior displacement of disc in 20/26 joints (76.9%), and condylar head position changes in 9/26 joints (34.6%). It is suggested that the advanced stage of internal derangement is closely associated with the degree of disc displacement. (author)

    Full Text Available Pathological changes that develop in the hip joints (HJ have different origins and mechanisms of development, but their main manifestation is pain. The nature of this pain cannot be well established on frequent occasions. The English-language medical literature currently classifies such disorders as greater trochanter pain syndrome (GTPS. Its major signs are chronic pain and local palpatory tenderness in the outer part of HJ. The development of GTPS may be associated with inflammation of the synovial bursae situated in the greater tronchanter, as well as with tendinitis, myorrhexis, iliotibial band syndrome, and other local changes in the adjacent tissues or with systemic diseases. So GTPS may be characterized as regional pain syndrome that frequently mimics pain induced by different diseases, including myofascial pain syndrome, osteoarthrosis, spinal diseases, etc.

    To validate the Pain Resilience Scale (PRS) for use in Chinese patients with temporomandibular disorders (TMD) pain. According to international guidelines, the original PRS was first translated and cross-culturally adapted to formulate the Chinese version of PRS (PRS-C). A total of 152 patients with TMD pain were recruited to complete series of questionnaires. Reliability of the PRS-C was investigated using internal consistency and test-retest reliability. Validity of the PRS-C was calculated using cross-cultural validity and convergent validity. Cross-cultural validity was evaluated by examining the confirmatory factor analysis (CFA). And convergent validity was examined through correlating the PRS-C scores with scores of 2 commonly used pain-related measures (the Connor-Davidson Resilience Scale [CD-RISC] and the Tampa Scale for Kinesiophobia for Temporomandibular Disorders [TSK-TMD]). The PRS-C had a high internal consistency (Cronbach's alpha = 0.92) and good test-retest reliability (intra-class correlation coefficient [ICC] = 0.81). The CFA supported a 2-factor model for the PRS-C with acceptable fit to the data. The fit indices were chi-square/DF = 2.21, GFI = 0.91, TLI = 0.97, CFI = 0.98 and RMSEA = 0.08. As regards convergent validity, the PRS-C evidenced moderate-to-good relationships with the CD-RISC and the TSK-TMD. The PRS-C shows good psychometric properties and could be considered as a reliable and valid measure to evaluate pain-related resilience in patients with TMD pain. © 2017 John Wiley & Sons Ltd.

    The classical technique for temporomandibular joint (TMJ) arthrocentesis provides a double access to the joint space, which may lead to patient's postoperatory discomfort. For this reason, a less invasive, single-needle approach has been recently described, and the present investigation reports findings on a case series of patients with TMJ osteoarthritis treated with hyaluronic acid injections following a single needle arthrocentesis. METHODS. Fourteen consecutive patients with a diagnosis of TMJ osteoarthritis according to the Research Diagnostic Criteria for Temporo-mandibular Disorders were treated with a cycle of five weekly injections of hyaluronic acid after arthrocentesis. A number of subjective (pain at rest and mastication, masticatory efficiency, functional limitation, subjective efficacy of treatment, tolerability of treatment) and objective (maximum assisted and unassited mouth opening, protrusive and laterotrusive movements) outcome variables were assessed before and after the treatment period. At the end of the five-injection protocol, significant improvements were showed in almost all the subjective outcome variables. Tolerability of the treatment was good on a four-point ordinal scale since the time of the first injection. The present investigation suggested that the single needle technique for TMJ hyaluronic injection following arthrocentesis in osteoarthritic joints may have promising applications in the clinical setting, which have to be confirmed with future studies.

    Fifty-three closed lock cases of internal derangement of the temporomandibular joint (TMJ) were studied on the correlation between disk configuration at MR imaging and nine clinical parameters composed of opening degree, age, clicking and locking duration, visual analogue scale of pain (VAS), pain score, jaw dysfunction score, life activity limited score, and TMJ X-ray photo findings. Disk configuration and degree of anterior disk displacement were assessed on MR imaging in closed mouth position: the antero-posterior length of disk and the distance from condyle to anterior and posterior portion of disk were measured, respectively. Duration of clicking and locking were not correlated with MR index except that there was a strong correlation between clicking duration and the distance from condyle to anterior portion of the disk at MR imaging. Opening degree was related to the disk deformity and the access of posterior portion of the disk to condyle. Disk configuration and degree of anterior disk displacement were not correlated with TMJ pain, but jaw dysfunction was related to the disk deformity and the distance from posterior portion of the disk to condyle. TMJ X-ray photo findings were not correlated with clicking duration (below 3 years), locking duration (below 30 weeks), opening degree and disk configuration at MR imaging. In evaluation of factors related to opening degree in 53 patients with closed lock by means of multiple regression analysis, age, locking and clicking duration, TMJ pain, life activity limited score were more strongly correlated to opening degree than the others.

    Full Text Available Temporomandibular joint (TMJ involvement occurs in patients with different rheumatic diseases (RDs. Pain, limitation of mouth opening can lead to significant problems in both oral hygiene and when eating. Conservative treatments for TMJ lesions are not always effective. Objective: to evaluate the efficiency of minimally invasive surgical interventions (TMJ arthrocentesis and arthroscopy in patients with RDs. Patients and methods. The investigation enrolled 64 patients with different RDs (43 with rheumatoid arthritis, 11 with psoriatic arthritis, 8 with systemic lupus erythematosus, and 2 with ankylosing spondylitis who were divided into three groups in relation to the severity of TMJ involvement in accordance with the Wilkes classification. All the patients underwent TMJ magnetic resonance imaging at baseline and 6 months after treatment. Also at baseline, 14 days, and 1, 6, and 12 months after surgery, the investigators assessed TMJ pain intensity by visual analogue scale and the parameters of mandibular movements. Patients with Wilkes stages IV and V TMJ involvement underwent arthroscopic intervention into the TMJ and those with III stage received TMJ arthrocentesis with arthrolavage. Results and discussion. After surgical treatment, all the groups were noted to have a significant decrease in TMJ pain intensity compared with the baseline level; moreover, the severity of TMJ pain most significantly decreased on day 7 after surgery. Later on, positive changes remained within subsequent follow-up months. There were data similar in the higher degree of mouth opening. The results of surgical treatment in patients with Wilkes stage V TMJ involvement were worse than in those with stages III and IV. Conclusion. Minimally invasive TMJ surgery in patients with RDs is effective and associated with the low frequency of postoperative complications and exacerbations of RDs. The efficiency of minimally invasive TMJ surgery is higher in patients with the

    We retrospectively reviewed the MRI findings of 100 temporomandibular joints in 78 patients who had complained temporomandibular joint dysfunction. MRI findings were classified according to Wilke's staging criteria. And these findings were compared with arthographic findings in 22 joint and surgical findings in 44 joints. According to Wilke's staging, they were classified into 6 stages of abnormality: stage 0 (33 cases), stage I (19 cases), stage II (10 cases), stage III (18 cases), stage IV (6 cases), stage V (14 cases). Among the 22 cases in which arthography and MRI were done, both studies were well correlated in 10 joints. In 7 joints, MRI was superior to arthography, which correctly demonstrated the meniscal displacement in 2 joints and meniscal deformity in 5 joints. In 5 joints, arthography was superior to MR, which demonstrated the perforation (1 joint), adhesion (2 joints) and recapture of meniscus (2 joints). Compared with surgical findings, MRI correctly demonstrated the displacement of meniscus in all 44 joints. However, in case of the 10 meniscal perforation, MRI demonstrated the meniscal discontinuity in only 4 joints. Retrospective MR findings in 10 proven cases were the defect in posterior attachment in 4, far anterior meniscal displacement without recapture in 8, condylar spur in 4, and close bone to bone contact in 1. In conclusion, MRI as a primary diagnostic modality of temporomandibular joint derangement, is superior for the grading of displacement and deformity of meniscus but inferior for the evaluation of perforation, adhesion and recapture of meniscus to conventional arthrography. In case of the suspected meniscal perforation, arthrographic correlation is recommended preoperatively

    Dislocation of temporo-mandibular joint (TMJ) is an infrequent disease but still spectacular. This disease consists of a permanent, to some extent complete disruption of the temporo-mandibular joint. These dislocations often occur in a context of yawning, and less frequently after a burst of laughing or relatively mild facial trauma (slap, punch on the chin). We report a case of TMJ occurring in an uncommon circumstance: vaginal delivery. A woman aged 24-years with no special past medical history; primipara was admitted in the Department of Maternity of the University Hospital Hassan II of Fez for an imminent delivery of a twin pregnancy. Ten minutes after admission, the patient delivered vaginally with episiotomy. She gave birth to twins weighing 2800 g and 2400 g. During labour, and due to efforts of crying, the patient developed a sudden and immediate loss of function of the temporo-mandibular joint, with difficulty of speaking, the mouth permanently opened and with the chin lowered and thrown forward. The examination found an empty glenoid fossa of the temporo-mandibular joint in both sides. The diagnosis of dislocation of the TMJ was established. A CT scan of facial bones was done, objectifying a bilateral dislocation of TMJ. The reduction of this dislocation was performed in the operating room under sedation.

    A 64-year-old woman with diabetes mellitus was admitted to our hospital with left hemiparesis of sudden onset. A brain MRI demonstrated a cerebral infarction in the ventral part of the right lower pons. When left hemiparesis worsened, she had dislocation of the temporo-mandibular joints repeatedly. Then, her lower jaw deviated to the right when she opened her mouth. Also, there was decreased contraction of the right masseter when she clenched her teeth. These findings suggest that there was trigeminal motor paralysis on the right side resulting from involvement of the intrapontine trigeminal motor nerve. She has no history of dislocation of the temporo-mandibular joints. An X-ray film showed that the temporo-mandibular joints were intact. Thus, it is possible that deviation of the lower jaw was the cause of this dislocation. We suspect that dislocation of the temporo-mandibular joints may occur as a complication of unilateral trigeminal motor paralysis. This has not been reported to our knowledge.

    2008-07-01

    Rear-end impacts account for more than one-third of vehicle accidents, and nearly 40% of these accidents produce whiplash injuries. Whiplash injury to the neck has often been considered a significant risk factor for the development of temporomandibular disorders (TMD). The objective of this study was to simulate the dynamic response of the temporomandibular joint during two types of impacts: a rear end and a frontal impact. To understand the dynamic forces acting on the joint, we extended a previous human temporomandibular joint model and analyzed the stress distributions in the soft elements of the joint. In the rear-end impact, it could be appreciated that the inertia of the mandible caused it to move posteriorly slower than the head, and this resulted in downward and forward displacements of the disc-condyle complex relative to the cranial base. Consequently, a rapid and big mouth opening occurs. In contrast, during the frontal impact, the mouth hardly opened, because the superior maxilla pushed the mandible to move together. There was not differential movement between bony components of the joint and therefore the soft tissues of the joint were not subjected to high loads. From these results, and despite the limitations of the simulations performed, we could conclude that neither a rear-end impact at low-velocity nor a frontal impact would produce damage to the soft tissues of the joint.

    The radiographic anatomy of the normal temporomandibular joint in newborns and children up to 4 years of age was investigated, partly on specimens, obtained at autopsy, with methods corresponding to clinical procedures, and partly on patients. A rather flat mandibular fossa and immature mandibular head were found at birth, whereas a well-developed articular tubercle and an adult-like radiographic appearance of the joint were found at about one year of age. No evident changes of the radiographic anatomy seemed to occur from one to 4 years of age. A striking similarity was observed between the dystrophic temporomandibular joint in patients with juvenile rheumatoid arthritis and micrognathia and the normal radiographic appearance in the first months of life, indicating an early involvement of this joint in patients developing micrognathia.

    A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries. This study was performed for the purpose of early detection and investigation of organic pathological changes in the cartilaginous and osseous tissues of the temporomandibular joint caused by traumatic fractures of the mandibular condyle. Twenty patients underwent a general clinical examination, magnetic resonance imaging (MRI), and immune-enzyme testing for biochemical markers of connective tissue injury (pyridinoline and deoxypyridinoline) in urine. Disk dislocation, deformation, adhesion, perforation or squeeze, tension or disruption of ligaments, and injury of articular surfaces are among complications of mandibular fractures that can be revealed on MRI. As regards biochemical findings, we revealed a sharp rise in the levels of pyridinoline and deoxypyridinoline before treatment and a lack of stabilization within 21 days of treatment.

    To report the temporo-mandibular joint (TMJ) kinetics and masticatory function in healthy children. Temporo-mandibular joint palpation and electrognathographic registrations of chewing cycles were repeated for 3 years in order to evaluate changes. Healthy children without systemic pathologies, decayed cavities and previous dental treatment. Electrognathographic (EGN) registration of masticatory cycles and TMJ palpation were carried out on 52 patients (mean age: 5 years 8 months, range: 5 years 1 month, 6 years 8 months), by two university researchers, once a year for 3 consecutive years. TMJ palpation, differentiated TMJ synchronism (simultaneous bilateral opening movement) and TMJ asynchronism (not simultaneous bilateral opening movement), TMJ subluxation and click were observed. Electrognathographic registrations differentiated normal and abnormal jaw chewing cycles, and narrow and large cycles. Temporo-mandibular joint asynchronism was evident in 34 of 52 patients in the primary dentition, in 42 of 52 patients after the eruption of the first permanent molar, and in 31 of 52 patients after the eruption of the permanent incisors. TMJ subluxation increased during the full period of observation. Three temporomandibular clicks appeared after the eruption of the permanent incisors. Altered mastication was not always associated with TMJ disorders. In children, normal chewing cycles can coexist with occlusal discrepancies, cranio-facial growth and TMJ alterations.

    According to American Academy of Orofacial Pain, 75% of the U.S. population experiences painful symptoms of temporo-mandibular joint and muscle disorder (TMJMD) during their lifetime. Thus, objective assessment of pain is crucial for efficient pain management. We used near infrared spectroscopy (NIRS) as a tool to explore hemodynamic responses in the frontal cortex to noxious thermal stimulation of temporomadibular joint (TMJ). NIRS experiments were performed on 9 healthy volunteers under both low pain stimulation (LPS) and high pain stimulation (HPS), using a temperature-controlled thermal stimulator. To induce thermal pain, a 16X16 mm2 thermode was strapped onto the right TMJ of each subject. Initially, subjects were asked to rate perceived pain on a scale of 0 to 10 for the temperatures from 41°C to 47°C. For the NIRS measurement, two magnitudes of temperatures, one rated as 3 and another rated as 7, were chosen as LPS and HPS, respectively. By analyzing the temporal profiles of changes in oxy-hemoglobin concentration (HbO) using cluster-based statistical tests, we were able to identify several regions of interest (ROI), (e.g., secondary somatosensory cortex and prefrontal cortex), where significant differences (ppain, a neural-network-based classification algorithm was used. With leave-one-out cross validation from 9 subjects, the two levels of pain were identified with 100% mean sensitivity, 98% mean specificity and 99% mean accuracy to high pain. From the receiver operating characteristics curve, 0.99 mean area under curve was observed.

    Objective: To analyze related factors on the number of mesenchymal stem cells in the synovial fluid of the temporomandibular joint (TMJ) and provide an research basis for understanding of the source and biological role of mesenchymal stem cells derived from synovial fluid in TMJ. Methods: One hundred and twenty-two synovial fluid samples from 91 temporomandibular disorders (TMD) patients who visited in Department of TMJ Center, Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University from March 2013 to December 2013 were collected in this study, and 6 TMJ synovial fluid samples from 6 normal volunteers who were studying in the North Campus of Sun Yat-sen University were also collected, so did their clinical information. Then the relation between the number of mesenchymal stem cells derived from synovial fluid and the health status of the joints, age of donor, disc perforation, condylar bony destruction, blood containing and visual analogue scale score of pain were investigated using Mann-Whitney U test and Spearman rank correlation test. Results: The number of mesenchymal stem cells derived from synovial fluid had no significant relation with visual analogue scale score of pain ( r= 0.041, P= 0.672), blood containing ( P= 0.063), condylar bony destruction ( P= 0.371). Linear correlation between the number of mesenchymal stem cells derived from synovial fluid and age of donor was very week ( r= 0.186, P= 0.043). The number of mesenchymal stem cells up-regulated when the joint was in a disease state ( P= 0.001). The disc perforation group had more mesenchymal stem cells in synovial fluid than without disc perforation group ( P= 0.042). Conclusions: The number of mesenchymal stem cells derived from synovial fluid in TMJ has no correlation with peripheral blood circulation and condylar bony destruction, while has close relation with soft tissue structure damage of the joint.

    This article describes the results of treating temporomandibular joint (TMJ) articular disc perforation and advanced chondromalacia arthroscopically by the use of discoplasty and abrasion arthroplasty. Forty-four joints were treated in 25 patients (23 females and 2 males). Twenty-nine disc perforations were present, 24 joints had grade III chondromalacia (fibrillated cartilage), and 14 joints had grade IV chondromalacia (exposed bone). Surgical procedures included 14 abrasion arthroplasties and 24 motorized shavings or holmium laser vaporizations. Holmium laser discoplasty with mobilization was used in 29 joints. Patients were followed-up for an average of 40.8 months (11 to 74 months). Preoperative pain on the visual analog scale (VAS) (1 to 10 cm) ranged from 5 to 10 cm, with an average of 7.4 cm. Postoperatively, nine patients had no pain and 16 patients had an average VAS of 2.7 cm (range, 1 to 5 cm). Preoperatively, 30 joints had clicking, and 14 joints had crepitation. Postoperatively, 25 joints had no noise, 12 joints had slight intermittent clicking, and seven joints had crepitation. The preoperative range of motion averaged 29.7 mm. Postoperatively, the range of motion averaged 37.7 mm (range, 33 to 42 mm). All patients could masticate a regular diet except hard food after an average of 40.8 months (11 to 74 months). These findings seem to justify the arthroscopic surgical procedures of discoplasty for disc perforations, motorized shaving, or holmium laser vaporization of grade III chondromalacia, and abrasion arthroplasty for bone exposure. The results also question the need for discectomy in the treatment of disc perforation.

    Background: disorders (TMDs) such as pain, joint sounds, and impaired movement are common, and magnetic resonance imaging (MRI) is now the method of choice for diagnostic assessment. Purpose: To describe MR criteria chosen and the amount of temporomandibular joint (TMJ) pathology registered when examining MR images from patients referred to a university hospital for imaging of their TMJs. Material and Methods: The TMJs of 152 consecutive patients, 102 women and 40 men, referred for MRI during an 18 month period were imaged with a 1.5 T imaging system. Twelve asymptomatic students, seven women and five men, gave informed consent and acted as a control group. Results: Moderate to extensive disk displacement was registered in 53% of the patients' TMJs, and 38% of the disks were deformed. Degenerative changes registered were flattening of the condyle heads in 50% of the TMJs and erosion of their cortical surfaces in 30%. Osteophytes were present in 31% of the condyles and bone marrow edema in 30%. Marked to extensive effusion in synovial compartments was registered in 39% of the studied TMJs. In the control group, none of the TMJs showed anterior disk displacement, deformed disks or degenerative changes, but 8 of the 24 joints showed marked effusion. A tendency for a higher amount of disk displacement and deformation was seen among young age groups and more degenerative changes in older age groups, but differences among groups were not significant when tested with chi-square analysis. Conclusion: Defined MR criteria that allow for comparative assessment are presented. According to these criteria, a large proportion of the patients referred for MR examination showed morphologic changes indicating TMJ pathology. Keywords Disk displacement, arthrosis

    The aims of this study was to compare the diagnostic accuracy of Conventional Radiography (CR). Radionuclide Angiography (RNA). Planar Scintigraphy (PS) and Single Photon Emission Computed Tomography (SPECT) for the evaluation of temporomandibular joint (TMJ) disorder; and to show whether technetium-99m-MDP uptake on quantitative SPECT correlated with the symptom and/or signs. Three Phase Bone Scintigraphy (TPBS) and SPECT of both TMJ were performed in 51 patients (M : F = 10 : 41 mean age= 30.4 :28.6, respectively) with unilateral TMJ disorder after an intravenous injection of 25 mCi (925 MBq) of 99mTc-MDP. Data were analyzed by creating three regions of interest (ROIs) over designated areas both on the PS and SPECT: Lesion (L). Non-lesion(NL) which is contralateral to L and Background (BG). L/ NL and L/BG (=[(L-BG)/500,000] x 100 (%)] ratios were calculated for each patients. L/NL ratios on SPECT were compared according to the symptom/signs or not. There was a fair correlation of L/N values between three slice-and seven slice-added SPECT images (r=0.5124, p=0.006, y=0.5588 + 0.5414X). The percentages of symptoms or signs were: pain (76.5%), mouth opening limitation (49.0%), joint sound (39.2%), discomfort (43.1%), headache(27.5%), neck stiffness (21.6%), closed lock (5.9%) / tenderness (47.1%), joint click (54.9%) and limitation of maximum mouth opening (45.1%). The Sensitive of SPECT(86.3%) was better than PS(66.7%), RNA(27.5%), and CR(26.3%). According to the presence of symptom/sign or not, comparative analysis of L/NL ratios on SPECT showed a fair correlation in pain (1.16 : 1.11) mouth opening limitation (1.21 : 1.09), joint sound (1.19 : 1.08), discomfort (1.22 : 1.09), headache (1.19: 1.13), tenderness (1.16 : 1.14) and limitation of maximum mouth opening (1.16 : 1.13), but little correlation in neck stiffness (1.12 : 1.15), closed lock (1.06 : 1.15), dislocation (1.08 : 1.15) joint click (1.12 : 1.18). In conclusion, quantitative SPECT is the noninvasive

    Chondrosarcoma is a malignant mesenchymal tumour of cartilaginous origin. It represents 11% of all malignant primary bone tumours, and the pelvis, ribs, femur and humerus are most frequently involved. Chondrosarcoma of the head and neck region is a rare disease, and represents approximately 0.1% of all head and neck neoplasms. This report describes a rare localisation of chondrosarcoma in a 56-year-old man who presented with swelling in the right preauricular area and mild limitation and pain in the mouth opening. Since 1959, just a few cases of temporomandibular joint (TMJ) chondrosarcoma have been described. Computed tomography revealed a large mass (39 x 46 x 40 mm) in the right preauricular and parotid region with morpho-structural alterations of the condyle and an intense periostotic reaction. The tumour was treated by total parotidectomy and condylotomy. The VII cranial nerve was preserved. Histopathologic examination revealed a low grade chondrosarcoma with a 50% proliferation index. At present, the patient is still receiving routine follow-up after radiotherapy and physiotherapy.

    Full Text Available Introduction and purpose: About 65% of children suffering from juvenile idiopathic arthritis (JIA shows a more or less marked involvement of temporo-mandibular joint (TMJ with altered mandibular growth, resorption of the condyles, occlusary instability, reduced chewing ability and facial dysmorphia. The purpose of our study is to prevent and to treat the progressive evolution of JIA on craniofacial growth and morphology with a functional appliance; surgery should be considered only in so far as the adequacy of TMJ movement is concemed. Methods: From 1992 until now 72 children with proved JIA and TMJ involvement have been treated (50 females, 22 males, aged 6 to 16 years old. TMJ involvement was bilateral in 61% and unilateral in 39% of patients. A diagnostic workup was carried out involving tomograms of TMJ and cephalometric radiograph and analysis. The authors used a bimaxillary activator in the attempt to modify the unfavourable growth pattern and provide a gradual ante-rotation of the jaw. Results: Almost all JIA patients showed satisfactory long term results, easing of pain, reduced skeletal discrepancy, increased function and good facial profile. Conclusions: The long term results of this study indicate that orthopaedic therapy might control the vicious circle of the malocclusion in children with JIA, preventing exacerbation of mandibular clockwise rotation. Surgical intervention for the improvement of TMJ function should be considered only if a severe restricted state is imminent.

    Full Text Available Introduction. Ankylosing spondylitis (AS/Morbus Bechterew is a chronic inflammatory rheumatoid disease. The temporomandibular joint (TMJ dysfunction is involved in 4–35% of AS cases, and is correlated to the severity and extension of AS. Even though AS-caused TMJ ankylosis is exceptional, one should have high index of suspicion of TMJ ankylosis in AS for an early detection, because it is an extremely serious and disabling condition that causes problems with mastication, swallowing, digestion, speech, appearance and poor oral hygiene with heavy caries. Case report. A 54-year-old male patient sought medical attention at the Department of Periodontology and Oral Medicine, Clinic for Dentistry at the Military Medical Academy, Belgrade, Serbia, with the chief complaint of pain in the area of the upper left canine in the presence of limited mouth opening. The treatment plan consisted of upper left canine management and rehabilitation of the remaining teeth in the frontal and the premolar region in both, the upper and lower jaw. Even though molar region needed to be treated, unfortunately it was not in the treatment plan because ankylosis of TMJ made the treatment impossible. Conclusions. The patients with AS-caused TMJ ankylosis are considered a diagnostic challenge to routine dentistry. Accent should be given to early diagnosis and multidisciplinary approach in the treatment of the AS patients towards the favorable disease course and outcome.

    Objective To describe CT findings in dogs and cats with temporomandibular joint (TMJ) disorders. Design Retrospective case-series. Animals 41 dogs and 17 cats. Procedures Medical records and CT images of the skull were reviewed for dogs and cats that were examined at a dentistry and oral surgery specialty practice between 2006 and 2011. Results Of 142 dogs and 42 cats evaluated, 41 dogs and 17 cats had CT findings consistent with a TMJ disorder. In dogs, the most common TMJ disorder was osteoarthritis; however, in most cases, there were other TMJ disorders present in addition to osteoarthritis. Osteoarthritis was more frequently identified at the medial aspect rather than the lateral aspect of the TMJ, whereas the frequency of osteoarthritic involvement of the dorsal and ventral compartments did not differ significantly. In cats, fractures were the most common TMJ disorder, followed by osteoarthritis. Clinical signs were observed in all dogs and cats with TMJ fractures, dysplasia, ankylosis, luxation, and tumors; however, only 4 of 15 dogs and 2 of 4 cats with osteoarthritis alone had clinical signs. Conclusions and Clinical Relevance Results indicated that TMJ disorders are frequently present in combination. Osteoarthritis was the most common TMJ disorder in dogs and the second most common TMJ disorder in cats. Computed tomography should be considered as a tool for the diagnosis of TMJ disorders in dogs and cats with suspected orofacial disorders and pain. PMID:23234284

    The purpose of this study is to describe the methodological innovations of a web-based system for storage, integration and computation of biomedical data, using a training imaging dataset to remotely compute a deep neural network classifier of temporomandibular joint osteoarthritis (TMJOA). This study imaging dataset consisted of three-dimensional (3D) surface meshes of mandibular condyles constructed from cone beam computed tomography (CBCT) scans. The training dataset consisted of 259 condyles, 105 from control subjects and 154 from patients with diagnosis of TMJ OA. For the image analysis classification, 34 right and left condyles from 17 patients (39.9 ± 11.7 years), who experienced signs and symptoms of the disease for less than 5 years, were included as the testing dataset. For the integrative statistical model of clinical, biological and imaging markers, the sample consisted of the same 17 test OA subjects and 17 age and sex matched control subjects (39.4 ± 15.4 years), who did not show any sign or symptom of OA. For these 34 subjects, a standardized clinical questionnaire, blood and saliva samples were also collected. The technological methodologies in this study include a deep neural network classifier of 3D condylar morphology (ShapeVariationAnalyzer, SVA), and a flexible web-based system for data storage, computation and integration (DSCI) of high dimensional imaging, clinical, and biological data. The DSCI system trained and tested the neural network, indicating 5 stages of structural degenerative changes in condylar morphology in the TMJ with 91% close agreement between the clinician consensus and the SVA classifier. The DSCI remotely ran with a novel application of a statistical analysis, the Multivariate Functional Shape Data Analysis, that computed high dimensional correlations between shape 3D coordinates, clinical pain levels and levels of biological markers, and then graphically displayed the computation results.

    The term "juvenile idiopathic arthritis" (JIA) encompasses a group of arthritis of unknown cause with onset before the age of 16 years that last for at least 6 weeks. The prevalence of temporomandibular joint involvement in published series ranges from 17% to 87%. Temporomandibular joint involvement is difficult to detect clinically, so imaging plays a key role in diagnosis and monitoring treatment. MRI is the technique of choice for the study of arthritis of the temporomandibular joint because it is the most sensitive technique for detecting acute synovitis and bone edema. Power Doppler ultrasonography can also detect active synovitis by showing the hypervascularization of the inflamed synovial membrane, but it cannot identify bone edema. This article describes the MRI technique for evaluating the temporomandibular joint in patients with juvenile idiopathic arthritis, defines the parameters to look for, and illustrates the main findings.

    Background The evaluation of possible differences in the distribution or characteristics of palpation-induced pain in the masticatory muscles could be valuable in terms of diagnostic assessment. The aim of this study was to evaluate the impact of different combinations of anterior temporalis (AT) and masseter palpation-induced pain in the diagnostic of temporomandibular disorder (TMD), primary headaches and bruxism. Material and Methods A total of 1200 dental records of orofacial pain adult patients were analyzed. The outcomes were dichotomously classified (presence/absence) as following: a) AT and/or masseter palpation-induced pain; b) myogenous TMD; c) temporomandibular joint (TMJ) arthralgia (arthrogenous TMD); d) migraine; e) tension-type headache (TTH); f) self-reported bruxism. Binomial logistic regression model (α = 5%) was applied to the data considering the palpation-induced muscle pain as the dependent variable. Results Mean age (SD) were 35.7 years (13.4) for 635 included dental records (83% females). Myogenous and arthrogenous TMD, migraine, TTH and bruxism were mainly associated with, respectively, masseter palpation-induced pain (ppain (ppain (ppain (p=0.009 - OR=1.62, 95%CI 1.12-2.33) and bilateral masseter palpation-induced pain (p=0.01 - OR=1.74, 95%CI 1.13-2.69). Conclusions Palpation-induced pain in the masticatory muscles may play a role in the differential diagnosis among painful TMD, primary headaches and bruxism.

    In a blind study, 243 arthrograms were interpreted as showing normal disk position, anterior disk displacement with reduction, or anterior disk displacement without reduction. The presence or absence of a perforation of the posterior attachment or disk was recorded. Later, tomograms of the same patient were interpreted. The presence or absence of evidence of temporomandibular degenerative joint disease (TMDJD) was recorded. The condyle-to-fossa relationship was characterized as retropositioned or not retropositioned. O the 106 cases with tomographic evidence of TMDJD, 100 (94%) had arthrographic evidence of internal derangement (p less than 0.0001), whereas 47% of the cases with internal derangement (211) had evidence of TMDJD. Perforations were seen in 29 (27%) of the cases with degenerative joint disease and in none (0%) of the cases without TMDJD (p less than 0.001). In cases without TMDJD, 90% of the cases with internal derangement revealed condylar retropositioning (p less than 0.0001). With tomographic evidence of TMDJD present, the relationship between condylar position and disk position was not significant.

    Full Text Available Abstract Background Relations between maxillo-mandibular deformities and TMJ disorders have been the object of different studies in medical literature and there are various opinions concerning the alteration of TMJ dysfunction after orthognathic surgery. The purpose of the present study was to evaluate TMJ disorders changes before and after orthognathic surgery, and to assess the risk of creating new TMJ symptoms on asymptomatic patients. Methods A questionnaire was sent to 176 patients operated at the Maxillo-Facial Service of the Lille's 2 Universitary Hospital Center (Chairman Pr Joël Ferri from 01.01.2006 to 01.01.2008. 57 patients (35 females and 22 males, age range from 16 to 65 years old, filled the questionnaire. The prevalence and the results on pain, sounds, clicking, joint locking, limited mouth opening, and tenseness were evaluated comparing different subgroups of patients. Results TMJ symptoms were significantly reduced after treatment for patients with pre-operative symptoms. The overall subjective treatment outcome was: improvement for 80.0% of patients, no change for 16.4% of patients, and an increase of symptoms for 3.6% of them. Thus, most patients were very satisfied with the results. However the appearance of new onset of TMJ symptoms is common. There was no statistical difference in the prevalence of preoperative TMJ symptoms and on postoperative results in class II compared to class III patients. Conclusions These observations demonstrate that: there is a high prevalence of TMJ disorders in dysgnathic patients; most of patients with preoperative TMJ signs and symptoms can improve TMJ dysfunction and pain levels can be reduced by orthognathic treatment; a percentage of dysgnathic patients who were preoperatively asymptomatic can develop TMJ disorders after surgery but this risk is low.

    This study was performed to determine the prevalence of bifid mandibular condyles (BMCs) in asymptomatic and symptomatic temporomandibular joint (TMJ) subjects with no traumatic history, and to assess their impact on clinical and radiographic manifestations of TMJ. A total of 3,046 asymptomatic and 4,378 symptomatic patients were included in the study. Cone-beam computed tomography (CBCT) images were reviewed for bifid condyles. T-tests were used to compare the frequency of BMCs when stratified by symptom, gender, and side. In BMC patients, the clinical features of pain and noise, osseous changes, and parasagittal positioning of the condyles were compared between the normally shaped condyle side and the BMC side using chi-squared tests. Fifteen (0.49%) asymptomatic and 22 (0.50%) symptomatic patients were found to have BMCs. Among the bilateral cases, the number of condyles were 19 (0.31%) and 25 (0.29%), respectively. No statistically significant differences were found between asymptomatic and symptomatic patients, between female and male patients, or between the right and left sides (p>0.05). Compared with the normally shaped condyle side, the BMC side showed no statistically significant differences in the distribution of pain and noise, parasagittal condylar position, or condylar osseous changes, with the exception of osteophytes. In the symptomatic group, osteophytes were found more frequently on the normally shaped condyle side than the BMC side (p<0.05). BMCs tended to be identified as an incidental finding. The presence of BMC would not lead to any TMJ symptoms or cause osseous changes.

    Tinnitus is frequently associated with temporomandibular joint (TMJ) dysfunction. However, the nature of the relationship is not fully understood. Here the authors compared 30 patients with a confirmed diagnosis of temporomandibular joint dysfunction and tinnitus to a group of 61 patients with tinnitus but without any subjective complaints of TMJ dysfunction with respect to clinical and demographic characteristics. Case-control study. Tertiary referral center. Tinnitus patients with and without TMJ dysfunction presenting at the Department of Prosthetic Dentistry and th: Tinnitus Clinic at the University of Regensburg. Tinnitus patients with TMJ disorder had better hearing function (P neck movements (P = .001). Classical risk factors for tinnitus (age, male gender, hearing loss) are less relevant in tinnitus patients with TMJ disorder, suggesting a causal role of TMJ pathology in the generation and maintenance of tinnitus. Based on this finding, treatment of TMJ disorder may represent a causally oriented treatment strategy for tinnitus.

    Osteohistometric studies were performed in 15 female and 15 male cadavers aged 18-25. Condyloid process and right and left acetabulum of the temporo-mandibular joint have been studied. Density has been investigated using monitor screen linked with microscope (magnification 80x). Density in the spongy part of the condyloid process was 26.67-26.77%; in the subchondrial layer--72.13-72.72%, and in the acetabular wall 75.03-75.91%. Microscopic structure of the bones of the temporo-mandibular joint revealed no differences when compared with images of compact and cancellous bone shown in the histology textbooks. Sex and the side of the body had no influence on microscopic image and proportional bone density. Isles of chondrocytes in the trabeculae of the spongy structure of the condyloid process were found in 4 cases and isles of the condensed bone resembling the compact pattern in 7 cases.

    The ectodermal dysplasias are a heterogenous group of diseases, which have one or more anomalies of the hair, teeth, nails, and sweat glands. Hypohidrotic ectodermal dysplasia (HED) is the most common type and is usually transmitted as an X-linked recessive trait. It is characterized by classical triad of hypotrichosis, anhidrosis/hypohidrosis, and hypodontia/anodontia. Here, we describe an Indian boy affected with HED and rare features including ankylosis of temporomandibular joint and cleft palate. PMID:25684924

    Pure trigeminal motor neuropathy (PTMN) is a rarely described condition. We report the case of a 41-year-old woman infected with the human immunodeficiency virus (HIV1) and hepatitis C virus who presented with weakness of left temporalis and masseter muscles and painful left temporomandibular joint dysfunction (TMD) a few months after cerebral toxoplasmosis revealing acquired immunodeficiency syndrome (AIDS). Magnetic resonance imaging revealed severe wasting and fat replacement of the left temporalis, pterygoid and masseter muscles and showed neither abnormalities in the left motor nucleus of the trigeminal nerve nor compression of the left trigeminal nerve. Electromyographic examination gave evidence of denervation in the left temporalis, masseter and pterygoid muscles and blink reflex studies were normal, confirming the diagnosis of PTMN which was probably secondary to HIV and HCV co-infection.

    The purpose of this study was to clarify the spatial relationship of temporomandibular joint and to an aid in the diagnosis of temporomandibular disorder. For this study, three-dimensional images of normal temporomandibular joint were reconstructed by computer image analysis system and three-dimensional reconstructive program integrated in computed tomography. The obtained results were as follows : 1. Two-dimensional computed tomograms had the better resolution than three dimensional computed tomograms in the evaluation of bone structure and the disk of TMJ. 2. Direct sagittal computed tomograms and coronal computed tomograms had the better resolution in the evaluation of the disk of TMJ. 3. The positional relationship of the disk could be visualized, but the configuration of the disk could not be clearly visualized on three-dimensional reconstructive CT images. 4. Three-dimensional reconstructive CT images had the smoother margin than three-dimensional images reconstructed by computer image analysis system, but the images of the latter had the better perspective. 5. Three-dimensional reconstructive images had the better spatial relationship of the TMJ articulation, and the joint space were more clearly visualized on dissection images.

    The present study was designed to verify the correlation between tinnitus and temporomandibular joint dysfunction.86 consecutive patients were enrolled in the study, all affected by subjective tinnitus without hearing impairment, from both genders, age between 18 and 60 years old. The final number of patients included in the study was 55. All patients received a temporo-mandibular joint examination. All the patients were asked to rate the severity of their symptoms before and after treatment using a VAS scale and the Tinnitus Handicap Inventory (THI) and they followed a standardized protocol for the investigation of tinnitus. All the subjects were monitored by the same researcher and they underwent the same splint treatment. The comparison between pre- and posttreatment phase scores showed in patients with predisposition of TMD and with TMD a statistically significant decrease of THI and VAS values. The characteristics of tinnitus and the degree of response to treatment confirmed the relationship between tinnitus and TMD. The authors believe that, when the most common causes of tinnitus, such as otologic disorders and neurological diseases are excluded, it is correct to evaluate the functionality of the temporo-mandibular joint and eventually treat its pathology to obtain tinnitus improvement or even resolution.

    Full Text Available BackgroundThis study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty.MethodsA prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation.ResultsA significant increase in interincisal distance of 32 mm was seen in 12 (92.31% patients in the T-plate interposition group, in 2 (25% cases of the temporalis muscle flap interposition group, and in 1 case (14.28% of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69% of the T-plate interposition group, while as it was observed in 4 (50% cases in the temporalis muscle flap interposition group and 4 (57.14% cases in the condylectomy group, and these differences were statistically significant.ConclusionsOur clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

  15. Pain acceptance, psychological functioning, and self-regulatory fatigue in temporomandibular disorder.

    2013-12-01

    A growing body of evidence suggests that chronic pain patients suffer from chronic self-regulatory fatigue: difficulty controlling thoughts, emotions, and behavior. Pain acceptance, which involves responding to pain and related experiences without attempts to control or avoid them (pain willingness), and pursuit of valued life activities regardless of pain (activity engagement) has been associated with various favorable outcomes in chronic pain patients, including better psychological functioning. The study presented here tested the hypotheses that pain acceptance is associated with less psychological distress, higher psychological well-being, and reduced self-regulatory fatigue in temporomandibular disorder (TMD) patients, particularly for those with longer pain duration. Cross-sectional data were provided by 135 TMD patients during an initial evaluation at a university-based tertiary orofacial pain clinic. Results of hierarchical linear regression models indicated that, controlling for pain severity, pain willingness is associated with less psychological distress and lower self-regulatory fatigue, and activity engagement is associated with greater psychological well-being. Furthermore, the effect of pain willingness on psychological distress was moderated by pain duration such that pain willingness was more strongly associated with less psychological distress in patients with longer pain duration; this moderating effect was fully mediated by self-regulatory fatigue. These findings suggest pain willingness may buffer against self-regulatory fatigue in those with longer pain duration, and such conservation of self-regulatory resources may protect against psychological symptoms.

    13 patients who sustained mandibular trauma were investigated with radiographs and scintiscans. The scintiscans showed abnormal uptake of radiopharmaceutical in the temporomandibular joint (TMJ). In patients with a long history of traumatic arthrosis, there was more positive correlation between the scintiscans, and clinical symptoms and histology than between radiographs, and symptoms and histology. In patients with mandibular body fractures and no TMJ symptoms, the scans showed abnormal uptake in the TMJ in 7/8 joints, in the absence of radiographic abnormality. The significance of the abnormal uptake and the value of scintigraphy is discussed.

    Comparison between orthopantomography, conventional radiography and lateral tomography for diagnosing arthritic lesions in the temporomandibular joints of 42 children with juvenile rheumatoid arthritis showed that each method seems to have diagnostic limitations. Concordance values of about 70 per cent were obtained. Most often destructive lesions of both the mandibular head and the fossa were observed at tomography. Secondary arthrosis, particularly sclerosis of the fossa, was most often diagnosed at conventional radiography. A combination of radiographic techniques seems to be most reliable for diagnosing arthritic joint abnormalities in children. (Auth.)

    A new technique of manufacturing dual-colour stereolithographic models of hard and soft tissues of the temporomandibular joint (TMJ) is presented. Sagittal T1/PD weighted magnetic resonance (MR) images of joints with and without disc displacement were obtained in the closed and open mouth positions. Individual interactive contour identification of bony structures and the articular disc followed by binary interpolation provided the data for the generation of acrylic TMJ models. Three dimensional in vivo visualization of the articular disc in relation to bony structures in the closed and open mouth positions allows a new perception of normal and pathological TMJ anatomy.

    The aim of this study is to present the preliminary clinical data on the OMX Temporomandibular Joint (TMJ) Prosthetic total joint replacement system. A prospective, cohort, clinical study was undertaken of consecutive adult patients with Category 5 end-stage joint disease who were implanted with the OMX TMJ prosthesis between May 2015 and April 2017. A total of 50 devices were implanted in 38 patients, with 12 patients receiving bilateral prosthetic joints. There were 31 females and 7 males in this cohort, who ranged in age from 20 to 66 years, with a mean of 43.8 years (±14.0 years). Ten of the 50 prosthetic joints (20%) were fully customized, while the remaining were patient matched using virtual planning software. Based on a mean follow-up period of 15.3 months (range 12-24 months) following the TMJ total joint replacement, preliminary results suggest the OMX TMJ prosthesis has made a positive impact on clinical outcomes, with a mean 74.4% reduction in joint pain levels and significant improvements (p < 0.05) in jaw function as measured by the visual analogue scales for mouth opening (30.8%), diet (77.1%), and function (59.2%). No device failures were reported during the study period. This study suggests that the print-on-demand OMX TMJ prosthesis, designed for rapid delivery of both patient-matched and fully customize devices, represents a safe, reliable and versatile implantable joint replacement system for the treatment of category 5 end-stage TMJ disease.

    To examine the possible relationship between condylar position and disk displacement in the temporomandibular joint. 79 temporomandibular joints in 40 patients having temporomandibular disorders were classified into three categories: no disk displacement (NDD), disk displacement with reduction (DDWR), and disk displacement without reduction (DDWOR). Disk positions were assessed from clinical and MRI findings. The relationship between the three categories and condylar positions was evaluated using lateral individualized corrected tomography. Clinical findings regarding the relationship between condyle and disk positions having anterior, centric, and posterior positions were 27%, 27%, and 46%, respectively, in NDD, 43%, 17%, and 40%, respectively, in DDWR, and 44%, 22%, and 34%, respectively, in DDWOR. There were no significant differences in condylar positions between each of the groups (P>0.05). In the relationship between condyle and disk positions with MRI findings, anterior, centric, and posterior positions were 38%, 38%, and 24%, respectively, in NDD, 29%, 21%, and 50%, respectively, in DDWR, and 44%, 9%, and 47% respectively, in DDWOR. There were significant differences in the condylar positions when MRI was utilized (P<0.05). There was a significant correlation between the condyle and disk positions with MRI findings on lateral individualized corrected tomography.

    The purpose of the present review is to systematically and critically analyze the available literature regarding the importance, applicability, and practicality of (MRI), computerized tomography (CT) or cone-beam CT (CBCT) image registration for TMJ anatomy and assessment. A systematic search of 4 databases; MEDLINE, EMBASE, EBM reviews and Scopus, was conducted by 2 reviewers. An additional manual search of the bibliography was performed. All articles discussing the magnetic resonance imaging MRI and CT or CBCT image registration for temporomandibular joint (TMJ) visualization or assessment were included. Only 3 articles satisfied the inclusion criteria. All included articles were published within the last 7 years. Two articles described MRI to CT multimodality image registration as a complementary tool to visualize TMJ. Both articles used images of one patient only to introduce the complementary concept of MRI-CT fused image. One article assessed the reliability of using MRI-CBCT registration to evaluate the TMJ disc position and osseous pathology for 10 temporomandibular disorder (TMD) patients. There are very limited studies of MRI-CT/CBCT registration to reach a conclusion regarding its accuracy or clinical use in the temporomandibular joints.

    Temporomandibular dysfunctions (TMD) comprise a great number of disruptions that may affect the temporomandibular joint (TMJ), the masticatory muscles, or both. TMJ internal derangement is a specific type of TMD, of which the etiology and physiopathology are broadly unknown, but have been suggested to be linked to head, neck, and body posture factors. This study aimed at verifying possible relationships between body posture and TMJ internal derangements (TMJ-id), by comparing 30 subjects presenting typical TMJ-id signs to 20 healthy subjects. Subjects' clinical evaluations included anamnesis, stomatognatic system evaluation, and plotting analysis on body posture photographs. No statistically significant differences were found between the groups. Results do not support the assertion that body posture plays a role in causing or enhancing TMD; however, these results should be cautiously considered because of the small number of subjects evaluated and the many posture variables submitted to statistical procedures that lead to high standard deviations.

    Full Text Available Drug induced dystonic reactions are among common presentations of patients in emergency departments, and typically occur with antidopaminergic agents as their extra-pyramidal side effects. Dystonic reactions usually occur within the first few hours or days after commencing a drug or dose increase. Unlike other extra-pyramidal side effects, a patient may experience acute dystonic reactions (ADRs with the administration of just a single dose. Oromandibular dystonia is a subtype of dystonia which can present with perioral manifestations. In extreme cases, it can lead to temporomandibular dislocation. Haloperidol, as a high potent typical antipsychotic drug, can induce dystonia with blocking D2 dopamine receptors. The present paper reports a case of bilateral dislocation of temporomandibular joint following ingestion of haloperidol in a suicidal attempt in a 17 years old girl.

    Full Text Available Internal derangements of the temporomandibular joint are conditions in which the articular disc has become displaced from its original position the condylar head. Relevant anatomic structures and their functional relationships are briefly discussed. The displacement of the disc can result in numerous presentations, with the most common being disc displacement with reduction (with or without intermittent locking, and disc displacement without reduction (with or without limited opening. These are described in this article according to the standardized Diagnostic Criteria for Temporomandibular Disorders, as well as the less common posterior disc displacement. Appropriate management usually ranges from patient education and monitoring to splints, physical therapy, and medications. In rare and select cases, surgery may be necessary. However, in for the majority of internal derangements, the prognosis is good, particularly with conservative care.

    A growing body of evidence suggests that bruxism exists in two separate manifestations. However, little is known about the association between specific manifestations of bruxism and temporomandibular disorder (TMD) pain. The aim of our study was to analyze the association between TMD pain and specific diagnoses of bruxism (sleep, awake, and mixed diagnosis of sleep and awake bruxism). 508 adult patients (296 women and 212 men), aged between 18 and 64 years (mean age 34±12 years), attending to a clinic for general dental treatment. Patients were asked to fill an anonymous questionnaire, consisting of three questions, verifying the presence of TMD pain and two forms of bruxism. All questions were based on the Polish version of the Research Diagnostic Criteria for Temporomandibular Disorders patient history questionnaire. Cross tabulation was done, and χ 2 was used as a test of significance to find the association between the variables. Awake bruxism was associated with TMD pain only in men (χ 2 =7.746, pbruxism was associated with TMD pain in both women (χ 2 =10.486, pbruxism and TMD pain. Gender-related differences in the presence of all bruxism diagnoses were also statistically insignificant. Interaction between sleep and awake bruxism may increase the risk for TMD pain. We suggest considering concomitance as a confounder, when studying sleep or awake bruxism. Copyright © 2016 Polish Neurological Society. Published by Elsevier Urban & Partner Sp. z o.o.

    Surgical trauma at the temporalis muscle is a potential cause of post-craniotomy headache and temporomandibular disorders (TMD). The aim of this study was to evaluate the prevalence of pain, masticatory dysfunction and trigeminal somatosensory abnormalities in patients who acquired aneurysms following pterional craniotomy. Fifteen patients were evaluated before and after the surgical procedure by a trained dentist. The evaluation consisted of the (1) research diagnostic criteria for TMD, (2) a standardized orofacial pain questionnaire and (3) a systematic protocol for quantitative sensory testing (QST) for the trigeminal nerve. After pterional craniotomy, 80% of the subjects, 12 patients, developed orofacial pain triggered by mandibular function. The pain intensity was measured by using the visual analog scale (VAS), and the mean pain intensity was 3.7. The prevalence of masticatory dysfunction was 86.7%, and there was a significant reduction of the maximum mouth opening. The sensory evaluation showed tactile and thermal hypoesthesia in the area of pterional access in all patients. There was a high frequency of temporomandibular dysfunction, postoperative orofacial pain and trigeminal sensory abnormalities. These findings can help to understand several abnormalities that can contribute to postoperative headache or orofacial pain complaints after pterional surgeries.

    79 patients aged 6 to 66 years (9 men and 70 women) with abnormalities of the TMJs were examined by magnetic resonance tomography (132 joints) and the results were compared with CT (16 joints) and resonance tomography showed forward luxation of the meniscus in 82 joints (62%). In 34 joints (26%) the meniscus spontaneously resumed normal position when the mouth was open, but in 48 joints (36%) the displacement was permanent. The accuracy of resonance tomography was equal to that of arthrography and superior to CT. It was particularly suitable for follow-up examination after surgery (23 cases) when invasive arthrography would be contraindicated or difficult. Because of the high resolution of the soft tissue components in the TMJ, resonance tomography should be able to diagnose inflammatory and degenerative changes in the meniscus and ligaments. (orig.)

    Arthrocentesis and prolotherapy are nonsurgical treatments for temporomandibular joint (TMJ) diseases. This study aimed to evaluate the treatment of hypermobility, pain, and displacement of the TMJ by consecutively performing arthrocentesis and prolotherapy in the same session. In this study, 10 adults with disc displacement and painful, hypermobile TMJ were selected. Arthrocentesis and prolotherapy were consecutively performed using a 30% dextrose solution that was simultaneously injected into five areas: posterior disc attachment, superior joint space, superior and inferior capsular attachments, and stylomandibular ligament. Paired t-test, McNemar test, and chi-square test were used to assess the maximum mouth opening, clicking sounds, pain, and subluxation of the TMJ. Patients with rheumatoid arthritis and parafunctional habits such as teeth clenching and grinding and biting of the cheeks or any other objects and those who had undergone surgery were excluded from this study. A total of 10 participants (36.20 ± 7.06 years old, 7 women and 3 men) received a single treatment session of combined arthrocentesis and prolotherapy at the same office visit. Subluxation frequency and pain significantly decreased after the first week of treatment (p < 0.05). Subluxation also decreased at the 3-month follow-up (p < 0.05). Clicking sound values did not significantly change at any of the follow-up time points. Maximum mouth opening values decreased at all follow-up time points compared to baseline (p < 0.05). A single session of combined arthrocentesis and prolotherapy to treat symptomatic TMJ safely and significantly improved the subluxation and pain after 1 week and subluxation after 3 months compared to baseline status. The maximum mouth opening significantly decreased at all follow-up time points. Future studies assessing multiple treatment sessions are warranted.

    Full Text Available Arthroscopic lavage and arthrocentesis, performed with different inner-diameter lavage needles, are the current minimally invasive techniques used in temporomandibular joint disc displacement (TMJ-DD for pain reduction and functional improvement. In the current study, we aimed to explore the biomechanical influence and explain the diverse clinical outcomes of these two approaches with computational fluid dynamics. Data was retrospectively analyzed from 78 cases that had undergone arthroscopic lavage or arthrocentesis for TMJ-DD from 2002 to 2010. Four types of finite volume models, featuring irrigation needles of different diameters, were constructed based on computed tomography images. We investigated the flow pattern and pressure distribution of lavage fluid secondary to caliber-varying needles. Our results demonstrated that the size of outflow portal was the critical factor in determining irrigated flow rate, with a larger inflow portal and a smaller outflow portal leading to higher intra-articular pressure. This was consistent with clinical data suggesting that increasing the mouth opening and maximal contra-lateral movement led to better outcomes following arthroscopic lavage. The findings of this study could be useful for choosing the lavage apparatus according to the main complaint of pain, or limited mouth opening, and examination of joint movements.

    The evaluation of possible differences in the distribution or characteristics of palpation-induced pain in the masticatory muscles could be valuable in terms of diagnostic assessment. The aim of this study was to evaluate the impact of different combinations of anterior temporalis (AT) and masseter palpation-induced pain in the diagnostic of temporomandibular disorder (TMD), primary headaches and bruxism. A total of 1200 dental records of orofacial pain adult patients were analyzed. The outcomes were dichotomously classified (presence/absence) as following: a) AT and/or masseter palpation-induced pain; b) myogenous TMD; c) temporomandibular joint (TMJ) arthralgia (arthrogenous TMD); d) migraine; e) tension-type headache (TTH); f) self-reported bruxism. Binomial logistic regression model (α = 5%) was applied to the data considering the palpation-induced muscle pain as the dependent variable. Mean age (SD) were 35.7 years (13.4) for 635 included dental records (83% females). Myogenous and arthrogenous TMD, migraine, TTH and bruxism were mainly associated with, respectively, masseter palpation-induced pain (pbruxism.

    The aim of this study was to explore the association between the presence of comorbidities and the pain experience in individual patients with temporomandibular disorder (TMD). This clinical trial comprised 112 patients with TMD pain. For all participants the presence of the following comorbid factors was assessed: pain in the neck; somatization; impaired sleep; and depression. Pain experience was evaluated using the McGill Pain Questionnaire (MPQ). For each subject the TMD-pain experience was assessed for three dimensions - sensory, affective, and evaluative - as specified in the MPQ. The association between comorbid factors and these three dimensions of TMD-pain experience was then evaluated using linear regression models. Univariable regression analyses showed that all comorbid factors, except for one factor, were positively associated with the level of pain, as rated by the sensory description of pain, the affective component of pain, and the evaluative experience of pain. The multivariable regression analyses showed that for all MPQ dimensions, depression showed the strongest associations with pain experience. It was found that in the presence of comorbid disorders, patients with TMD experience elevated levels of TMD pain. This information should be taken into consideration in the diagnostic process, as well as in the choice of treatment. © 2016 Eur J Oral Sci.

    Full Text Available Abstract Background The aim of this study was to test whether a reciprocal dose-response relation exists between frequency/severity of spinal pain and temporomandibular disorders (TMD. Methods A total of 616 subjects with varying severity of spinal pain or no spinal pain completed a questionnaire focusing on symptoms in the jaw, head and spinal region. A subset of the population (n = 266 were sampled regardless of presence or absence of spinal pain. We used two different designs, one with frequency/severity of spinal pain, and the other, with frequency/severity of TMD symptoms as independent variable. All 616 participants were allocated to four groups, one control group without spinal pain and three spinal pain groups. The subjects in the subset were allocated to one control group without TMD symptoms and three TMD groups. Odds ratios (ORs were calculated for presence of frequent TMD symptoms in the separate spinal pain groups as well as for frequent spinal pain in the separate TMD groups. Results The analysis showed increasing ORs for TMD with increasing frequency/severity of spinal pain. We also found increasing ORs for spinal pain with increasing frequency/severity of TMD symptoms. Conclusion This study shows a reciprocal dose-response-like relationship between spinal pain and TMD. The results indicate that these two conditions may share common risk factors or that they may influence each other. Studies on the temporal sequence between spinal pain and TMD are warranted.

    Synovial chondromatosis (SC) is an uncommon disease characterized by a benign nodular cartilaginous proliferation arising from the joint synovium, bursae, or tendon sheaths. Although the temporomandibular joint is rarely affected by neoplastic lesions, SC is the most common neoplastic lesion of this joint. The treatment of this disease consists in the extraoral surgery with a wide removal of the lesion; in this study, the authors described a more conservative intraoral surgical approach. Patient with SC of temporomandibular joint typically refer a limitation in the mouth opening, together with a persistent not physiological mandibular protrusion and an appearance of a neoformation located at the right preauricular region: the authors reported 1 scholar patient. After biopsy of the neoformation, confirming the synovial chondromatosis, the patient underwent thus to the surgical excision of the tumor, via authors' conservative transoral approach, to facilitate the enucleation of the neoformation. The mass fully involved the pterygo-maxillary fossa with involvement of the parotid lodge and of the right TMJ: this multifocal extension suggested for a trans-oral surgical procedure, in the light of the suspicion of a possible malignant nature of the neoplasm. Our intraoral conservative approach to surgery is aimed to reduce the presence of unaesthetic scars in preauricular and facial regions, with surgical results undoubtedly comparable to the traditional surgical techniques much more aggressive. Our technique could be a valid, alternative, and safe approach to treat this rare and complex kind of oncological disease.

    Full Text Available Background: Fractures of the mandibular condyle may lead to complications such as disturbance of occlusal function, internal derangement of the joint, ankylosis and mandibular growth disturbance. When treating young patients with the history of mandible trauma, ankylosis of the temporomandibular joint and mandibular growth disturbance are two most important complications of condyle fracture that should be considered. Purpose: This case report attempts to emphasize the long term complication of neglected condylar fracture in children i.e. ankylosis of the temporomandibular joint and subsequently lead to mandibular growth disturbance. Case: A case of right temporo-mandibular joint ankylosis and mandibular growth disturbance in a 28 years old male patient is presented. He had a history of trauma to the mandible after a traffic accident when he was 8 years old. Since then, he experienced difficulty in mouth opening which eventually developed into severe trismus. Case management: The case was treated surgically with gap and interpositional arthroplasty using Mersilen mesh™. Conclusion: Mandibular fractures involving temporomandibular joint in young children should be examined thoroughly and treated adequately in order to prevent ankylosis of the TMJ and the subsequent mandibular growth disturbance.Latar belakang: Fraktur pada kondilus mandibula dapat menyebabkan beberapa komplikasi berupa: gangguan oklusi, internal derangement sendi, ankilosis serta gangguan pertumbuhan mandibula.

    Virtually all the articles in literature addressed only a specific type of dislocation. The aim of this review was to project a comprehensive understanding of the pathologic processes and management of all types of dislodgement of the head of the mandibular condyle from its normal position in the glenoid fossa. In addition, a new classification of temporomandibular joint dislocation was also proposed. A thorough computer literature search was done using the Medline, Cochrane library and Embase database. Key words like temporo-mandibular joint dislocation were used for the search. Additional manual search was done by going through published home-based and foreign articles. Case reports/series, and original articles that documented the type of dislocation, number of cases treated in the series and original articles. Treatment done and outcome of treatment were included in the study. A total of 128 articles were reviewed out which 79 were found relevant. Of these, 26 were case reports, 17 were case series and 36 were original articles. 79 cases were acute dislocations, 35 cases were chronic protracted TMJ dislocations and 311 cases were chronic recurrent TMJ dislocations. Etiology was predominantly trauma in 60% of cases and other causes contributed about 40%. Of all the cases reviewed, only 4 were unilateral dislocation. Various treatment modalities are outlined in this report as indicated for each type of dislocation. The more complex and invasive method of treatment may not necessarily offer the best option and outcome of treatment, therefore conservative approaches should be exhausted and utilized appropriately before adopting the more invasive surgical techniques.

The aim of this review is to evaluate the recent evidence, identify challenges, and propose solutions from a clinical point of view for patients with craniofacial pain and TMD. The treatment we propose is structured in a multimodal approach based on a biobehavioral approach that includes medical, physiotherapeutic, psychological, and dental treatments. We also propose a new biobehavioral model regarding pain perception and motor behavior for the diagnosis and treatment of patients with painful TMD.

    Background Petrotympanic fissure (PTF) is a fissure in the temporal bone that runs from the temporomandibular joint (TMJ) to the tympanic cavity (TC). In PTF, the discomallear ligament (DML) connects the malleus in the tympanic cavity and the articular disc and capsule of the temporomandibular joint. PTF with the DML is a possible cause of aural symptoms related to temporomandibular joint dysfunction (TMD). Purpose To investigate the prevalence of different types of PTF in TMD using dental volumetric tomography (DVT) and determine whether PTF type correlates with age. Material and Methods DVT scans in the sagittal planes of PTFs of 134 patients with TMD were examined for the types of PTF present. Three main PTF types were described: wide, tunnel-shaped structure (type 1); tunnel-shaped structure that is wide open in the PTF entrance to the mandibular fossa and gradually thins out in the tympanic cavity (type 2), tunnel-shaped structure that is wide open in the entrance of the mandibular fossa, with a middle region with a flat-shaped tunnel structure and a narrow exit in the tympanic cavity (type 3). Results In DVT scans, PTF types 1, 2 and 3 were seen in 67.2%, 1.5%, and 31.3% of cases, respectively. We found no significant relationship between age or gender and PTF type. Conclusion The low percentage of type 2 PTF and high percentage of type 1 PTF must be taken into consideration during pre-surgical planning related to TMD. However, future well-designed clinical studies involving larger numbers of subjects will be necessary to confirm the findings of this study

    Background Petrotympanic fissure (PTF) is a fissure in the temporal bone that runs from the temporomandibular joint (TMJ) to the tympanic cavity (TC). In PTF, the discomallear ligament (DML) connects the malleus in the tympanic cavity and the articular disc and capsule of the temporomandibular joint. PTF with the DML is a possible cause of aural symptoms related to temporomandibular joint dysfunction (TMD). Purpose To investigate the prevalence of different types of PTF in TMD using dental volumetric tomography (DVT) and determine whether PTF type correlates with age. Material and Methods DVT scans in the sagittal planes of PTFs of 134 patients with TMD were examined for the types of PTF present.

    Background The main objective of this paper is to analyze the prevalence of each of the different clinical subtypes of temporomandibular disorders (TMD) in a sample of patients with this pathology. In addition, a second objective was to analyze their distribution according to gender. Material and Methods To this end, the results of 1603 patients who went to the Unit of Temporomandibular Disorders in the Córdoba Healthcare District because they suffered from this pathology were analyzed. In order to diagnose them, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were applied, analyzing the different Axis I subtypes (myopathy, discopathy and arthropathy) and obtaining the combined Axis I for each patient and the relation of all these variables according to gender. The null-hypothesis test confirmed the lack of connection between the gender variable and the different subtypes in the clinical analysis, and between the former and the combined Axis I of the RDC/TMD. Results The prevalence was high for the muscle disorders subtype in general, showing an 88.7% prevalence, while the presence of discopathies or arthropathies was much lower. Among discopathies, the most frequent ones were disc displacements with reduction, with 39.7% and 42.8% for the left and right temporomandibular joints (TMJ), respectively, while the prevalence of arthropathies was 26.3% for the right TMJ and 32.9% for the left TMJ. The bivariate analysis on the connection with gender reveals a p≥ 0.05 value for the muscle and arthralgia subtypes. Conclusions The patients seen at the TMD Unit where mostly middle-aged women whose main clinical axis subtype was the muscle disorder subtype. For their part, both discopathies and arthropathies, although present, are much less prevalent. Key words:RDCTMD, axis I, orofacial pain, temporomandibular disorders, gender. PMID:26615508

    Microwave plasma chemical vapour deposition of nanostructured diamond films was carried out on curved surfaces of Ti-6Al-4V alloy machined to simulate the shape of a temporomandibular joint (TMJ) dental implant. Raman spectroscopy shows that the deposited films are uniform in chemical composition along the radius of curvature of the TMJ condyle. Thin film x-ray diffraction reveals an interfacial carbide layer and nanocrystalline diamond grains in this coating. Nanoindentation hardness measurements show an ultra-hard coating with a hardness value of 60{+-}5 GPa averaged over three samples. (rapid communication)

    Numerous procedures have been described for the treatment of chronic recurrent dislocation of the temporo-mandibular joint (TMJ), either in the form of enhancement or restriction of the condylar movement, with their obvious merits and demerits. We present a new technique of using U shaped iliac bone graft to restrict the condylar movement and its advantages over the conventional techniques.We have used this technique successfully in 8 cases where Dautrey's procedure had failed with follow up period of 2 years. No patient complained of recurrent dislocation postoperatively. This a very simple and effective technique where other procedures have failed.

    Full Text Available Intubating a patient with temporomandibular joint ankylosis is always a challenge particularly when fibreoptic laryngo-scope is not available. In a 20-year-old male patient we successfully carried out endotracheal intubation with 7 mm portex cuffed PVC tube with the help of two flexible J tipped guide wires. One guide wire was passed into the airway from cricothyroid puncture site and another from subcricoid site. Both were brought out through the nose. The first guide wire was used for retracting the epiglottis and the second as a guide for passing the endotracheal tube.

    We report a case of a 66-year-old white woman with calcium pyrophosphate dihydrate (CPPD) crystal deposition disease. The patient related a 2-month history of swelling with tenderness over the left pre-auricular region. A CT scan suggested a synovial chondromatosis. Surgical removal was done and histologic study showed CPPD crystals. This disease rarely involves the temporomandibular joint (TMJ) and is not usually considered in the differential diagnosis. To our knowledge, only 14 cases have been reported in the literature. (orig.)

    One hundred and ten patients with psoriatic arthritis (PA) and 100 matched control patients were examined by using orthopantomography to discover radiographic changes in the condyle of the temporomandibular joint (TMJ). 31% of the PA patients and 13% of the control patients had radiographic changes in the condyle of the TMJ. The most common radiographic finding in PA patients was unilateral erosion of the condyle. Of the radiographic changes in the PA group, cortical erosions correlated negatively with age, whereas osteophytes correlated positively with the duration of PA. (orig.)

    To conduct a systematic review of papers reporting the reliability and diagnostic validity of the joint vibration analysis (JVA) for diagnosis of temporomandibular disorders (TMD). A search of Pubmed identified English-language publications of the reliability and diagnostic validity of the JVA. Guidelines were adapted from applied STAndards for the Reporting of Diagnostic accuracy studies (STARD) to evaluate the publications. Fifteen publications were included in this review, each of which presented methodological limitations. This literature is unable to provide evidence to support the reliability and diagnostic validity of the JVA for diagnosis of TMD.

    The Carey-Finema-Ziter syndrome (CFZS, MIM 254940) is an apparently autosomal recessively inherited disorder consisting of the combination of non-progressive congenital myopathy with Moebius and Pierre Robin sequence, facial anomalies and growth delay. Mental development has been described as normal or delayed. Temporomandibular joint (TMJ) ankylosis is the immobility of the joint caused by ankylotic fusion of the mandible to the cranial base or zygoma. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and oral hygiene. Most often is a true ankylosis of the TMJ but other pathological mechanisms are described (i.e., the fusion of the coronoid process to temporal bone or with the zygoma, or a variety of soft tissues disorders like Fibrodysplasia Ossificans Progressiva). Here we report a 2-year-old girl fitting with a clinical diagnosis of CFZS associated with a limited mouth opening in which temporomandibular joint ankylosis was suspected. Because it has been postulated that many clinical features in CFZS may only be secondary effects of brainstem anomalies and muscle weakness during development, the limited opening of the mouth observed in our patient could represent a rare clinical feature of CFZS itself. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    2015-12-01

    Full Text Available Tophaceous pseudogout, a variant of calcium pyrophosphate dihydrate deposition, is a relatively rare juxta-articular disease. It is a metabolic condition, in which patients develop pseudo-tumoral calcifications associated with peri-articular structures secondary to calcium pyrophosphate deposition into joints with fibrocartilage rather than hyaline cartilage. These lesions are reported in the knee, wrist, pubis, shoulder, and temporomandibular joint (TMJ and induce a histocytic foreign body giant cell reaction. We report a case of tophaceous pseudogout affecting the left TMJ with destruction of the condyle and glenoid and middle cranial fossa that was reconstructed with a TMJ Concepts (Ventura, CA custom-fitted prosthesis in a 2-staged surgical approach using a silicone spacer. The surgical management using a patient-specific TMJ is a viable option when the fossa or condylar component has been compromised due to breakdown of bone secondary to a pathologic process. Our case describes and identifies the lesion and its rare occurrence in the region of the temporomandibular region. The successful management of tophaceous pseudogout of the TMJ must include a thorough patient workup including the involvement of other joints as well as the modification of bone of the glenoid fossa and condylar relationship of the TMJ.

    .PURPOSE: to submit an oral miofunctional therapeutic proposal, the procedures used in cases of bilateral ankylosis of the temporomandibular and the results, joint standing out the importance of interdisciplinary work and the oral miofunctional therapy contribution to rehabilitation of the stomatognatic system in these cases. METHODS: this case report is about an adult, male, referred to evaluation and specific procedures three months after the joint surgery. Core complaint was great restriction of mouth opening range. The oral miofuncional exam assessment has shown: mouth opening of 25 mm, lack of laterality and protrusion movements, previous open bite of 8 mm, difficulty in chewing, swallowing, speech articulation and pain in temporal muscles. The therapeutical objectives were: stimulate and allow the execution of mandible movements, preventing restrictive cicatricial tissue and functional rehabilitation. Procedures related to increasing the amplitude through looseness, stretching, massages, and specific maneuvers as distraction and lever had been essential to stabilize the opening of the mouth, to liberate the mandible movements partially and to co-ordinate them as long as it improves the functionality of the stomatognatic system. RESULTS: after 24 sessions were: gain of 16 mm in the opening, passing to 41 mm with stability according to annual control; reduction of the previous bite open for 4 mm; improvement in the hygienic cleaning, in the speech articulation, in the alimentary conditions with acquisition of chewing strength and reduction of the compensatory mechanisms; elimination of pain in the region of the temporal muscles in addition to improvement in the facial esthetics. CONCLUSION: the oral miofunctional therapeutic reveals itself efficient in adult with bilateral ankylosis of the temporomandibular joint, after surgical procedure, with stability of results maintained according to annual control.

    To evaluate the risk of self-reported temporomandibular disorder (TMD) pain among adolescents in relation to previous head and/or neck injury. 3,101 enrollees (11 to 17 years of age) of a nonprofit integrated health-care system were interviewed by telephone. Two hundred four cases with self-reported TMD pain and 194 controls without self-reported TMD pain frequency-matched to the cases by age and gender completed standardized in-person interviews and physical examinations in which reports of previous head/neck injuries were recorded. Odds ratio (OR) estimates and 95% confidence intervals (CIs) of the relative risks of TMD pain associated with prior head and/or neck injuries were calculated using logistic regression. A greater proportion of subjects reporting TMD pain (36%) than controls (25%) had a history of head and/or neck injuries (OR = 1.8, 95% CI, 1.1-2.8). In a separate analysis, the presence of TMD based upon the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was assessed in relation to prior head and/or neck injury. Cases reporting TMD pain and meeting the RDC/TMD criteria for myofascial pain and/or arthralgia or arthritis were 2.0 (CI, 1.0-3.8) times more likely to have had a prior head injury than were controls with neither self-reported nor RDC/TMD pain diagnoses. The results suggest a modest association of prior head injuries with both self-reported and clinically diagnosed TMD pain in adolescents.

    Jaw movement is analyzed as an action between two rigid components jointed together in a particular way, the movable mandible against the stabilized cranium. Opening and closing movements are symmetrical; that is, both sides of the cranio-mandibular articulation are making the same movements. Protrusive and retrusive movements may also be symmetrical. The mandibular muscles determine all the complicated postures and-movements of the jaw. Their behavior can be greatly clarified by restating certain fundamentals crucial to purposive muscular activity. The joint derives its arterial supply from the superficial temporal artery and the maxillary artery. Branches of the auriculo-temporal and masseteric nerves and postganglionic sympathetic nerves supply the tissues associated with the capsular ligament and the looser posterior bilaminar extension of the disc.

    The purpose of the present study was to explore the potential use of platelet-rich-plasma (PRP) in the treatment of temporomandibular joint osteoarthritis (TMJ-OA). Surgical defects were created bilaterally on the condylar fibrocartilage, hyaline cartilage, and bone to induce an osteoarthritic TMJ in rabbits. PRP was applied to the right joints of the rabbits (PRP group), and the left joints received physiologic saline (control group). After 4 weeks, the rabbits were sacrificed for histologic and scanning electron microscopy (SEM) examinations. The data were analyzed statistically. The new bone regeneration was significantly greater in the PRP group (P fibrocartilage and hyaline cartilage was greater in the PRP group, no statistically significant difference was found between the 2 groups. SEM showed better ultrastructural architecture of the collagen fibrils in the PRP group. PRP might enhance the regeneration of bone in TMJ-OA.

    1985-01-01

    A prospective study to determine the accuracy of computed tomography (CT) for the diagnosis of dislocation of the temporomandibular joint (TMJ) meniscus was made by performing both CT and contrast arthrography on 18 joints suspected of meniscus dislocation. Arthography rather than surgery was chosen as the quality standard for comparing CT findings, as not all patients undergoing the studies underwent surgery. The results of each test were reported independently by the radiologist who obtained either all of the arthograms or all of the CT scans. For dislocation of the meniscus, there were excellent agreement between the two methods. CT seems to be nearly as accurate as arthrography for showing meniscus dislocation, is performed with lower x-ray exposure, and is noninvasive. Arthrograpy discloses more detailed information about the joint meniscus, such as perforation and maceration, and should continue to be used when this kind of information is clinically important

    The use of artificial joint implants has risen greatly over the past years. However, few investigations of the cancer risk associated with implants have been performed. We investigated cancer risk in patients with finger and hand joint and temporo-mandibular (TMJ) joint implants. A nationwide cohort in Denmark of patients with finger and hand joint prostheses (n = 858) or TMJ implants (n = 389) was followed from January 1, 1977, to December 31, 1995, to evaluate any potential cancer risks subsequent to receiving these implants. Standardized incidence ratios (SIRs) for all cancers were 1.0 (95% CI = 0.8-1.2) for the finger and hand joint cohort and 1.1 (95% CI = 0.8-1.7) for the TMJ cohort. A significant risk for non-Hodgkin's lymphoma was found in the finger and hand joint cohort (SIR = 3.8, 95% CI = 1.5-7.8). When the finger and hand joint cohort was stratified by diagnosis of rheumatoid arthritis, the excess risk was seen only in the group with rheumatoid arthritis. This is consistent with past studies, which have found an association between rheumatoid arthritis and non-Hodgkin's lymphoma. Our results provide evidence that the cancer risk for patients with finger and hand joint prostheses and TMJ implants is similar to that for the general population.

    Articular dysfunction of the TMJ with anterior displacement of the disc ("internal derangement") is an entity which has been separated from other types of the "myofascial pain syndromes" and which can be treated conservatively or by surgery. Arthrography of the TMJ has contributed greatly to an understanding of normal and abnormal function and, in many cases, it can provide a diagnosis. On the basis of our experience with 80 investigations we discuss technical problems and the clinical indications. The indications for arthrography are in the pre-operative diagnosis, when clinical findings are uncertain, in order to demonstrate perforation, in order to confirm a suspected diagnosis and to assist in prosthetic treatment.

    Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels conduct an inward cation current (Ih ) that contributes to the maintenance of neuronal membrane potential and have been implicated in a number of animal models of neuropathic and inflammatory pain. In the current study, we investigated HCN channel involvement in inflammatory pain of the temporomandibular joint (TMJ). The contribution of HCN channels to inflammation (complete Freund's adjuvant; CFA)-induced mechanical hypersensitivity of the rat TMJ was tested with injections of the HCN channel blocker ZD7288. Retrograde labelling and immunohistochemistry was used to explore HCN channel expression in sensory neurons that innervate the TMJ. Injection of CFA into the TMJ (n = 7) resulted in a significantly increased mechanical sensitivity relative to vehicle injection (n = 7) (p blocked by co-injection of ZD7288 with the CFA (n = 7). Retrograde labelling and immunohistochemistry experiments revealed expression predominantly of HCN1 and HCN2 channel subunits in trigeminal ganglion neurons that innervate the TMJ (n = 3). No change in the proportion or intensity of HCN channel expression was found in inflamed (n = 6) versus control (n = 5) animals at the time point tested. Our findings suggest a role for peripheral HCN channels in inflammation-induced pain of the TMJ. Peripheral application of a HCN channel blocker could provide therapeutic benefit for inflammatory TMJ pain and avoid side effects associated with activation of HCN channels in the central nervous system. © 2012 European Federation of International Association for the Study of Pain Chapters.

    According to the International Association for the Study of Pain (IASP), the term temporomandibular disorder (TMD) regards a subgroup of orofacial pain, the symptoms of which include pain or discomfort in the temporomandibular joint, ears, masticatory muscles and neck on one or both sides, as well as joint sounds, limited mandibular movements or mandibular deviation and difficulties chewing. Phototherapy, such as low-level laser therapy (LLLT) and light-emitting diode (LED) therapy, is one of the resources used to treatment muscle pain. Thus, there is a need to investigate therapeutic resources that combine different wavelengths as well as different light sources (LLLT and LED) in the same apparatus. The aim of the proposed study is to evaluate the effects of four different doses of phototherapy on pain, activity of the masticatory muscles (masseter and bilateral anterior temporal) and joint mobility in individuals with temporomandibular disorder. A further aim is to determine the cumulative effect 24 and 48 hours after a single session. A placebo-controlled, double-blind, randomized, clinical trial will be carried out involving 72 women between 18 and 40 years of age with a diagnosis of myogenous TMD. The participants will then be randomly allocated to four groups totaling 18 individuals per group. Three groups will be submitted to a single session of phototherapy with different light sources, and one group will receive placebo therapy: Group A (2.62 Joules); Group B (5.24 Joules); Group C (7.86 Joules); and Group D (0 Joules). The following assessment tools will be administered on four separate occasions (baseline and immediately after, 24 h after and 48 h after phototherapy). Pain intensity will be assessed using the visual analog scale for pain, while pain thresholds will be determined using algometer, and electromyographic (EMG) analysis on the masseter and anterior temporal muscles. The study will contribute to the practice of the evidence-based use of

    Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is a relatively common benign tumor of the skeleton, occurring most often in the metaphyseal region of long bone. However, it is rare in the facial bones. Reported foci in the mandible were the condyle, coronoid process, and symphysis region. Synovial chondromatosis is an uncommon benign condition of unknown etiology which affects the articular joints. Foci of cartilage develop through metaplasia in the underlying connective tissue of the synovial membrane. These cartilagenous foci and fragments may undergo calcification and ossification. We experienced 4 patients with abnormal appearance of mandibular condyle. This report describes 3 cases of osteocondroma and 1 case of synovial chondromatosis of the mandibular condyle with review of the literature

    Full Text Available OBJECTIVE: To evaluate perceived coercion (PC of noninstitutionalized elderly patients undergoing research for the diagnosis of temporomandibular joint dysfunction. METHOD: A cross-sectional study conducted with 1,112 elderly individuals aged 60 or older, enrolled in the Family Health Programme of the municipality of Areia, State of Paraíba, Brazil, from January to June 2013. The data collection tool was the Perceived Cohesion Scale (PSC. RESULTS: The participants were predominantly women (62.5% in the 60 to 69 age group (45.9%, illiterate (57.9% percent, married or in a common law marriage (54.1%, retired (83.6%, and receiving a monthly income under the minimum wage (72.0%. The average overall PC was 1.25+ 1.15 and Trend 1 (41,4%. There was a difference between the group of individuals who were literate, married and in a common law marriage and the members of the other groups. CONCLUSION: Results showed that the elderly patients were minimally coerced when deciding whether to participate in research for diagnosing temporomandibular joint dysfunction. They also revealed a significant association of PC with literacy and marital status.

    This systematic review provides an overview of the historical evolution of the prosthetic temporomandibular joint and addresses the challenges and complications faced by engineers and surgeons, in an effort to shed light on why only a few systems remain available. A better understanding of the history of temporomandibular joint prostheses might also provide insights into the origin of the negative public opinion of the prosthesis, which is based on outdated information. A computerized search using the PubMed Central, ScienceDirect, Wiley Online, Ovid, and Cochrane Library databases was performed following the PRISMA guidelines. Out of 7122 articles identified, 41 met the inclusion criteria for this systematic review. Although several historical reviews have been published previously, none has covered such an extensive time period or has described all designs. Furthermore, besides providing a historical overview, this review discusses the rationale behind the evolution in design and biomaterials, which have largely contributed to the outcomes of the prosthetic systems.

    Full Text Available Background : Fiberoptic intubation is the gold standard technique for difficult airway management in patients of temporomandibular joint. This study was aimed to evaluate the clinical efficacy and safety of dexmedetomidine as premedication with propofol infusion for fiberoptic intubation. Methods: Consent was obtained from 46 adult patients of temporomandibular joint ankylosis, scheduled for gap arthroplasty. They were enrolled for thisdouble-blind, randomized, prospective clinical trial with two treatment groups - Group D and Group P, of 23 patients each. Group D patients had received premedication of dexmedetomidine 1 μg/kg infused over 10 min followed by sedative propofol infusion and the control Group P patients were given only propofol infusion to achieve sedation. Condition achieved at endoscopy, intubating conditions, hemodynamic changes and postoperative events were evaluated as primary outcome. Results : The fiberoptic intubation was successful with satisfactory endoscopic and intubating condition in all patients. Dexmedetomidine premedication has provided satisfactory conditions for fiberoptic intubation and attenuated the hemodynamic response of fiberoptic intubation than the propofol group. Conclusion : Fiberoptic intubation was found to be easier with dexmedetomidine premedication along with sedative infusion of propofol with complete amnesia of the procedure, hemodynamic stability and preservation of patent airway.

    Pathologies currently defined as temporomandibular disorders may be different in nature. Temporomandibular joint (TMJ) disorders and craniofacial and cervical myogenous pain (MP) are distinct pathologies but may be superimposed and share some etiologic factors. Tension-type headache (TTH) may often be associated with craniofacial and cervical pain, and the same pharmacologic and nonpharmacologic treatment may be efficacious for both. Psychiatric comorbidity (depression and/or anxiety disorder) is less frequent in sheer TMJ disorders, compared with MP and TTH. A screening for the presence of an underlying psychiatric disorder should be part of the clinical evaluation in patients suffering from headache and facial pain.

    .Recent studies have shown consistent results using the physical therapy in cases of pain and limitation of movement from temporomandibular dysfunction. Thus, our objective was to assess the effect of ten sessions of physical therapy and laser therapy in treatment of muscular pain and arthralgias in a woman with temporomandibular dysfunction. The painful symptoms relief achieved by session was over 20 %, up to zero at the end of treatment. Results demonstrated that the treatment protocol used was effective to reduce the temporomandibular joint and the masseter muscle tension and a decreased of drugs by patient. However, more studies are needed to define with more accuracy the effect of other physiotherapy programs and its interaction with other treatment modalities.

    Pain of the tempro-mandibular joint (TMJ) has a direct bearing to missing teeth and excessive physical activity. Consumption of qat requires chewing on the leaves to extract their juice for long hours. A 65-year-old male Yemeni patient, a Qat chewer, reported to the university dental hospital at King Khalid University complaining of pain in left temporomandibular joint with missing mandibular anterior teeth. A multidisciplinary approach for the overall treatment of the patient was decided. Initial treatment was the relief of patient's pain with the help of a night guard. This was followed by a fabrication of anterior FPD. The case was under maintenance and follow-up protocol for a period of 8 months with no complaint of pain discomfort.

    1990-01-01

    Fifty-three randomly selected subjects with psoriatic arthritis (PA) were examined radiographically by means of orthopantomography, transcranial radiography, and transmaxillary radiography. Two examiners graded the radiographic signs of flattening, osteophytes, erosion, and sclerosis. The findings obtained were then compared to determine the best technique for screening of temporomandibular joint (TMJ) bone changes. Together the techniques showed definite (24%) and possible (6%) changes, suggesting TMJ involvement in 31 of 106 joints. In all projections, radiographic signs suggesting TMJ involvement were most frequent in the condyle. Erosion in the condyle was the most frequent finding. Agreement with regard to definite changes in the condyle was found in only one-third to half of the cases. It is concluded that in radiography of the TMJ in subjects with PA, a combination of radiographic techniques should be used to obtain maximum information. However, orthopantomography is well suited for screening of TMJ involvement in subjects with PA. 30 refs., 2 figs., 3 tabs

    Using an autoradiographic method, the temporomandibular joint (TMJ) complex of five aged female baboons was studied for the presence of receptors for estradiol-17 beta. The study was performed in an effort to learn more of the pathophysiology of this joint and in an attempt to provide a scientific basis to explain the reported preponderance of women who seek and undergo treatment for signs and symptoms referable to the TMJ. This experiment revealed that the TMJ complex contains numerous cells with receptors for estrogen, particularly the articular surface of the condyle, articular disk, and capsule. Muscles of mastication contained relatively fewer receptors. As a result, one may postulate a role for the sex steroid hormones in the maintenance, repair, and/or pathogenesis of the TMJ. Additional studies are necessary to fully determine the significance of hormone receptors in this site and any correlation between diseases of the TMJ and the endocrine status of affected patients.

    To evaluate displacement and morphologic changes of the temporomandibular joint (TMJ) disc in patient with internal derangement using magnetic resonance imaging (MRI). One hundred and forty five MR images of TMJs in 73 patients were evaluated. Positional and morphologic changes of the TMJ disc were assessed. Lateral or medial disc displacement was also evaluated on cornal images. Among 63 discs with anterior disc displacement, 37 discs were assessed as a biconcave disc and 21 as a deformed disc. Rotational disc displacement was observed in 35 disc. Anteromedial disc displacement was observed in 29 discs, and anterolateral direction in 6 discs. Among 35 rotational displacement, 5 biconcave discs and 21 deformed discs were observed. Rotational and sideways displacement of TMJ discs were found to be common and an important aspect of internal derangement. This study also suggests that sagittal and coronal images of the TMJ have complementary abilities for an assessment of joint abnormality

    Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder of the synovial membrane. PVNS generally affects large joints but occasionally involves the temporomandibular joint (TMJ), with occasional extension into the middle cranial fossa. The purpose of this study was to report our experience with PVNS along with a focused literature review. Patients with PVNS of the TMJ treated at the University of California - San Francisco from 2007 to 2013 were reviewed. A PubMed search was performed to identify additional cases. Five patients underwent surgical resection, with 1 recurrence at 61 months. A literature review identified 58 patients, 19 of which had intracranial involvement. Interestingly, intracranial extension was more common in men. Intracranial extension was not associated with an increased rate of recurrence. PVNS of the TMJ is a rare entity associated with excellent outcomes, even with intracranial extension. Management should consist of maximal resection, with radiotherapy reserved for extensive or recurrent lesions. © 2014 Wiley Periodicals, Inc.

    OBJECTIVES: The temporomandibular joints (TMJs) are frequently affected in children with juvenile idiopathic arthritis (JIA). Early detection is challenging, as major variation is present in scoring TMJ pathology on Magnetic Resonance Imaging (MRI). Consensus-driven development and validation...... of a MRI scoring system for TMJs has important clinical utility in timely improvement of diagnosis, and serving as an outcome measure. We report on a multi-institutional collaboration towards developing a TMJ MRI scoring system for JIA. METHODS: Seven readers independently assessed MRI scans from 21...... preferable for assessing minor joint changes over time. Eight items were considered sufficiently reliable and/or important for integration into the consensus scoring system: bone marrow edema and enhancement (avICC=0.57-0.61; %SDD=±45-63% prior to re-defining), condylar flattening (0.95-0.96; ±23...

    2013-12-01

    Clinicians who address temporomandibular joint (TMJ) pathology and dentofacial deformities surgically can perform the surgery in 1 stage or 2 separate stages. The 2-stage approach requires the patient to undergo 2 separate operations and anesthesia, significantly prolonging the overall treatment. However, performing concomitant TMJ and orthognathic surgery (CTOS) in these cases requires careful treatment planning and surgical proficiency in the 2 surgical areas. This article presents a new treatment protocol for the application of computer-assisted surgical simulation in CTOS cases requiring reconstruction with patient-fitted total joint prostheses. The traditional and new CTOS protocols are described and compared. The new CTOS protocol helps decrease the preoperative workup time and increase the accuracy of model surgery.

    1988-01-01

    Triple correlation of MR imaging with arthrography, arthroscopy, and open surgery was performed in 24 patients (34 temporomandibular joints) with ages ranging from 17 to 66 years. MR imaging showed disk position and morphologic features accurately in 30 joints (88%). It was false negative in one joint and false positive in three joints (9%). Degenerative changes were accurately detected with MR imaging, arthrography, and arthroscopy. Adhesions were diagnosed with arthrography in eight joints, arthroscopy in 14, and MR imaging in none. Disk perforations seen at open surgery were not detected with MR imaging. In conclusion, there is an overlap of information presented by various modalities. MR imaging is better than arthrography detecting disk morphologic features and displacement. Arthrography may add information by showing meniscal dynamics. Arthroscopy entails direct observation of superior joint space only and can detect adhesions and perforations better, but it may alter disk position and dynamics. In the more difficult cases, triple correlation may be needed, as modalities can be complementary

    Full Text Available The aim of this study was to compare treatment outcomes following intramuscular injection of botulinum neurotoxin (BoNT in patients with recurrent temporomandibular joint dislocation, with and without muscle hyperactivity due to neurological diseases. Thirty-two patients (19 women and 13 men, mean age: 62.3 years with recurrent temporomandibular joint dislocation were divided into two groups: neurogenic (8 women and 12 men and habitual (11 women and 1 man. The neurogenic group included patients having neurological disorders, such as Parkinson’s disease or oromandibular dystonia, that are accompanied by muscle hyperactivity. BoNT was administered via intraoral injection to the inferior head of the lateral pterygoid muscle. In total, BoNT injection was administered 102 times (mean 3.2 times/patient. The mean follow-up duration was 29.5 months. The neurogenic group was significantly (p < 0.001 younger (47.3 years than the habitual group (84.8 years and required significantly (p < 0.01 more injections (4.1 versus 1.7 times to achieve a positive outcome. No significant immediate or delayed complications occurred. Thus, intramuscular injection of BoNT into the lateral pterygoid muscle is an effective and safe treatment for habitual temporomandibular joint dislocation. More injections are required in cases of neurogenic temporomandibular joint dislocation than in those of habitual dislocation without muscle hyperactivity.

    MRI manifestation of temporomandibular joint arthritis is frequently reported in children with juvenile idiopathic arthritis. However, little attention has been paid to temporomandibular joint disk abnormalities. To assess combinations of MRI findings in the symptomatic temporomandibular joint in children with juvenile idiopathic arthritis with focus on disk abnormalities. This was a retrospective study of 46 patients with juvenile idiopathic arthritis, mean age 12 years (range: 5-17 years). Mean disease duration was 70 months (standard deviation: 61 months). MR images of 92 temporomandibular joints were scored for thickness of abnormally enhancing synovium (synovitis), joint effusion, bone marrow oedema, abnormal bone shape, bone erosion and disk abnormalities. The 92 temporomandibular joints were categorized as A: No synovitis and normal bone shape (30/92; 33%), B: Synovitis and normal bone shape (14/92: 15%), C: Synovitis and abnormal bone shape (38/92; 41%) and D: No synovitis but abnormal bone shape (10/92; 11%). Thirty-six of the 46 patients (78%) had synovitis and 33/46 (72%) had abnormal bone shape, most frequently in combination (30/46; 65%). Disk abnormalities (flat disk, fragmented disk, adherent disk and displaced disk) were found in 29/46 patients (63%). Disk abnormalities were found in all categories of juvenile idiopathic arthritis involved temporomandibular joints (B: 8/14 [57%]; C: 25/38 [66%] and D: 7/10 [70%]). Disk displacement was found in half of the joints (7/14) in category B. Synovitis was most pronounced in this category. Disk abnormalities were frequent. Disk displacement also occurred in joints with early temporomandibular joint arthritis, i.e., with normal bone shape. Other disk abnormalities were found in joints with bone abnormalities. Attention should be paid to disk abnormalities both in early and long-standing temporomandibular joint arthritis in children with juvenile idiopathic arthritis. (orig.)

    MRI manifestation of temporomandibular joint arthritis is frequently reported in children with juvenile idiopathic arthritis. However, little attention has been paid to temporomandibular joint disk abnormalities. To assess combinations of MRI findings in the symptomatic temporomandibular joint in children with juvenile idiopathic arthritis with focus on disk abnormalities. This was a retrospective study of 46 patients with juvenile idiopathic arthritis, mean age 12 years (range: 5-17 years). Mean disease duration was 70 months (standard deviation: 61 months). MR images of 92 temporomandibular joints were scored for thickness of abnormally enhancing synovium (synovitis), joint effusion, bone marrow oedema, abnormal bone shape, bone erosion and disk abnormalities. The 92 temporomandibular joints were categorized as A: No synovitis and normal bone shape (30/92; 33%), B: Synovitis and normal bone shape (14/92: 15%), C: Synovitis and abnormal bone shape (38/92; 41%) and D: No synovitis but abnormal bone shape (10/92; 11%). Thirty-six of the 46 patients (78%) had synovitis and 33/46 (72%) had abnormal bone shape, most frequently in combination (30/46; 65%). Disk abnormalities (flat disk, fragmented disk, adherent disk and displaced disk) were found in 29/46 patients (63%). Disk abnormalities were found in all categories of juvenile idiopathic arthritis involved temporomandibular joints (B: 8/14 [57%]; C: 25/38 [66%] and D: 7/10 [70%]). Disk displacement was found in half of the joints (7/14) in category B. Synovitis was most pronounced in this category. Disk abnormalities were frequent. Disk displacement also occurred in joints with early temporomandibular joint arthritis, i.e., with normal bone shape. Other disk abnormalities were found in joints with bone abnormalities. Attention should be paid to disk abnormalities both in early and long-standing temporomandibular joint arthritis in children with juvenile idiopathic arthritis. (orig.)

    Headache and temporomandibular disorders should be treated together but separately. If there is marked limitation of opening, imaging of the joint may be necessary. The treatment should then include education regarding limiting jaw function, appliance therapy, instruction in jaw posture, and stretching exercises, as well as medications to reduce inflammation and relax the muscles. The use of physical therapies, such as spray and stretch and trigger point injections, is helpful if there is myofascial pain. Tricyclic antidepressants and the new-generation antiepileptic drugs are effective in muscle pain conditions. Arthrocentesis and/or arthroscopy may help to restore range of motion.

    Aim: To compare clinical feasibility of static two-dimensional (2D) to three-dimensional (3D) sonography of the temporomandibular joint (TMJ) in assessment of disk dislocation and joint degeneration compared to magnetic resonance imaging (MRI). Method: Thirty-three patients, 66 TMJ were prospectively sonographed 2D and 3D (8-12.5 MHz step motor scan), in occlusion and maximum opening with a probe position parallel inferior to the zygomatic arch. Axial 2D images were judged independent from the 3D scans; 3D volumes were cut axial, sagittal, frontal and rotated in real-time. Disk position and joint degeneration were assessed and compared to a subsequent MRI examination. Results: The specific appearance of the disk was hypoechogenic overlying a hyperechogenic condyle in axial (2D) or sagittal and frontal (3D) viewing. Specificity of 2D sonography for disk dislocation was 63%, sensitivity 58%, accuracy 64%, positive predictive value 46%, negative predictive value 73%; for joint degeneration synonymously 59/68/61/38/83%. 3D sonography for disk displacement reached synonymously 68/60/69/51/76%, for joint degeneration 75/65/73/48/86%. 2D sonographic diagnoses of disk dislocation in the closed mouth position and of joint degeneration showed significantly different results from the expected values (MRI) in {chi} {sup 2} testing; 3D diagnoses of disk dislocation in closed mouth position, of joint degeneration, 2D and 3D diagnoses in open mouth position were nonsignificant. Conclusions: Acceptable was the overall negative predictive value, as specificity and accuracy for joint degeneration in 3D. 3D appears superior diagnosing disk dislocation in closed mouth position as for overall joint degeneration. Sensitivity, accuracy and positive predictive value will have to ameliorate with future equipment of higher resolution in real-time 2D and 3D, if sonographic screening shall be clinically applied prior to MRI.

    To evaluate the diagnostic accuracy of transcranial radiographs and magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) in the assessment of osseous changes of the condylar head and articular eminence. Osseous changes of the TMJ were evaluated in forty-three patients. Osseous changes of the condylar head and articular eminence were observed in 41 joints and 64 joints, respectively on transcranial radiographs, and 48 joints and 59 joints, respectively on MRI. The flattening, sclerosis, erosion, and osteophyte formation of the condylar heads were observed in 36.6%, 43.9%, 12.2%, and 7.3%, respectively on transcranial radiographs compared with 35.4%, 20.8%, 37.5%, and 6.3%, respectively on MRI. While, the flattening, sclerosis, and erosion of the articular eminences were observed in 26.6%, 67.2%, and 6.2%, respectively on transcranial radiographs compared with 32.2%, 59.3%, and 8.5%, respectively on MRI. There were no statistical differences between transcranial radiographs and MRI scans in the detection of osseous changes of the TMJ. However, MRI scans were superior to the transcranial radiographs in the detection of erosion of the condylar head (p<0.01).

    To explore the selection of temporomandibular joint (TMJ) disc reduction and fixation methods in condylar sagittal fracture surgery. A total of 36 patients with condylar fractures were chosen. The follow-up period was more 6 months. All 36 cases of condylar sagittal fracture were fixed with long screw. In the operation, the displaced joint disc was repositioned and fixed. The fixed method included direct suture (22 cases) and anchorage (14 cases). Clinical followups were performed before surgery and 1 month, 3 months, 6 months and 1 year after surgery. Clinicians recorded data related to the Fricton craniomandibular index (CMI) and evaluated the postoperative joint function during followup before surgery and 6 months after surgery. In both groups, function of TMJ significantly improved after surgery. The CMI decreased from 0.213±0.162 and 0.273±0.154 to 0.059±0.072 and 0.064±0.068 (P0.05) before or after surgery. Both methods could effectively improve the dysfunction of the TMJ caused by trauma. The selection of joint disc reduction and fixation methods is based on the displacement and damage degree of the joint disc.

    This is a histological study of the human temporo-mandibular joint and its surrounding muscles. Using a microscopic study of serial sections from anatomical specimens from six subjects, the detailed anatomy of the joint is presented with particular regard to the histology. This study has allowed, in particular, the description of the ligaments and capsule as well as the insertions of the masticatory muscles (temporalis, masseter, lateral pterygoid) on this joint. These observations are then compared with the anatomical and histological data already reported on this subject. This study shows that the bulk of the muscular fibres of the lateral pterygoid passes under the foot of the disc is attached over the whole height of the condylar, unite and extend as far as the medial pole of the joint under the insertion of the articular disc. An insertion of the temporo-masseter musculo-tendinous complex on the anterior and lateral capsulo-discal structures was observed. The lateral pterygoid is composed of a succession of tendinous and fleshy fibres. This study confirms the thickening of the lateral capsule that corresponds to a lateral collateral ligament, and the absence of a medial collateral ligament. Medial stability is conferred by the lateral ligament of the contralateral joint.

    To assess dental students' achieved competencies and perceived satisfaction with their temporomandibular disorders (TMD) and orofacial pain education and to compare these with the results of their final examination in TMD and orofacial pain. Dental students from two consecutive classes (2011/2012 and 2012/2013) at the Department of Orofacial Pain and Jaw Function at the dental school in Malmö, Sweden completed two self-evaluations, one at the beginning of semester seven and one at the end of semester eight. The questionnaire that they were given concerned achieved competencies and satisfaction with education in TMD and orofacial pain. Items focused on anatomy, physiology, and clinical training. Students estimated their competence and satisfaction on a numeric rating scale and described their idea of treating TMD and orofacial pain patients on a verbal rating scale. Outcome variables were tested with paired samples t test for differences over time and independent samples t test for between-class comparisons; both were adjusted for multiple testing with Bonferroni correction. Significant improvement in all items was observed for achieved competencies and satisfaction in both classes between semester seven and semester eight (P .05). This study has shown that expansion in undergraduate TMD and orofacial pain education at the dental school in Malmö has allowed all students to develop the same level of competence, independent of prior experience. The study also pointed out that continuous evaluation and enhancement of TMD and orofacial pain education in undergraduate dental education is beneficial.

    Total prosthetic replacement of the temporo-mandibular joint (TMJ) has become a common procedure, but it is usually limited to the TMJ itself. We report about one case of complex prosthetic joint reconstruction extending to the neighbouring bony structures. A 57-year-old patient, operated several times for a cranio-facial fibrous dysplasia, presented with a recurring TMJ ankylosis and a complexe latero-facial bone loss on the right side. We performed a reconstruction procedure including the TMJ, the zygomatic arch and the malar bone by mean of custom made composite prosthesis (chrome-cobalt-molybdenum-titanium and polyethylene). Five years postoperatively, mouth opening, nutrition, pain and oral hygiene were significantly improved. Nowadays technical possibilities allow for complex facial alloplastic reconstructions with good medium term results. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    The purpose of this study was to assess the tissue alterations in the temporomandibular joint (TMJ) of the New Zealand White rabbit (Oryctolagus cuniculus L.), after a unilateral occlusal interference insertion on the animal's right side back teeth. A total of 36 animals were used, thirty of which belonged to the experimental group and six to the control group. We established three experimental periods: 24 hours, three days and seven days. The control group animals were divided two by two; each pair followed the same experimental periods of the former one. The experimental group animals were submitted to the use of a 0.3 mm thick metallic cap with a visor. All animals were euthanized, and the TMJs were removed. Using a microscope for examination we observed, in all experimental periods, the presence of intra-articular hemorrhage in the supra- and infra-disk compartments as well as in the retro-disk zone. There were no inflammatory cells detected. The thickness of the condylar fibrocartilage presented significant alterations among the animals of the three experimental groups. In the left TMJs no inflammatory cells were detected. The results suggest that the insertion of a unilateral occlusal interference in rabbit back teeth does not cause any inflammatory intra-articular process within seven days; however, it does cause bilateral intra-articular hemorrhage and a larger compression of the condylar fibrocartilage in the joint opposite the side where the interference is placed. We also concluded that, in order to do research on the temporomandibular joint using animals, it is necessary have an independent (or separate) group of animals as controls.

    The objective of this systematic review was to examine the effect of orthognathic surgery (OS) on the temporomandibular joint and oral function. Electronic databases were systematically searched for studies published until October 2015. Articles were assessed against predefined inclusion criteria. The included papers were divided into four groups based on the type of OS performed. The following items were recorded: quality of evidence using the Oxford Centre for Evidence-Based medicine (CEBM) criteria, number of patients, presence/absence of controls, mean age at treatment, follow-up time, clinical examination findings, bite force, use of the Helkimo Index and Research Diagnostic Criteria for Temporomandibular Disorders, imaging findings, and patient questionnaire results. A total of 4669 articles were identified; 76 relevant articles were included in the review. These studies assessed a total 3399 patients and 380 controls, with a mean age of 25.4 years. The great variety of OS techniques, examination techniques, diagnostic criteria, and imaging techniques used in the articles studied, as well as the quality of the study designs, made it difficult to compare studies and to draw conclusions. However, looking at the different aspects studied in general, it can be stated that OS seems to have little or no harmful effect on the TMJ and oral function (level of evidence: levels II, III, and IV).

    The aim of the present study was to assess the relationship between temporomandibular joint disorder (TMJD) and headache in children and adolescents. A prospective cross-sectional cohort study was carried out involving 93 children and adolescents (6 to 14 years of age) at the outpatient service of a dental school. All participants underwent a clinical examination involving Axis 1 of the Research Diagnostic Criteria for Temporomandibular Disorders, along with a characterization of headache and an anthropometric evaluation. Statistical analysis involved the chi-squared test for quantitative variables and the Student's t-test, ANOVA and Tukey's test for quantitative data. An adjusted logistic regression model was used to determine significant associations among gender, age, TMJD and headache. Mild TMJD was identified in 35.8% of the sample and was not associated the presence of headache. Moderate TMJD was found in 25.8% of patients and severe TMJD was found in 11.8%; both forms of TMJD were associated with headache. A significant correlation was found between the intensity of TMJD and the risk of headache. The present findings demonstrate a positive correlation between TMJD and headache in children and adolescents, independently of gender and age.

    The most common temporomandibular joint (TMJ) internal derangement is an abnormal relationship of the disc with respect to the mandibular condyle, articular eminence and glenoid fossa-disc displacement. The aim of our study was to analyse the correlation between partial/complete disc displacement in the intercuspal position (IP) and its reduction in the open-mouth position (OMP) in both oblique sagittal and coronal planes on magnetic resonance imaging (MRI) in patients with temporomandibular disorders. Multisection MRI analysis of 382 TMJs was conducted in 191 patients with disc displacement according to the RDC/TMD criteria (148 women, 43 men; aged 14-60 years). The disc position was evaluated on all oblique sagittal and coronal images in the IP and the OMP. Univariate logistic regression analysis showed that the severity of disc displacement in the sagittal plane is a statistically significant predictor of reduction ability during mouth opening (B = 3.118; P displacement in both planes is also a significant predictor of disc reduction in OMP (B = 2.200; P displacement in IP, in both sagittal and coronal planes. Multisection analysis of all MR images allows distinguishing the correct disc position from disc displacement and can improve the ability to distinguish between various stages of TMJ internal derangement. © 2017 John Wiley & Sons Ltd.

    The purpose of this study was to evaluate and review the diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of imaging diagnosis for temporomandibular disorders. The role of diagnostic imaging is to detect and document specific anatomic abnormalities associated with the signs and symptoms in the temporomandibular joint. Magnetic resonance imaging (MR imaging) can accurately depict disc displacement and disc deformity. MR imaging is our first choice among the various imaging modalities for the patients with clinical signs and symptoms. However, it has been shown that intra-capsular adhesions and perforations of the disc and retrodiscal tissue are sometimes not detected by MR imaging. To improve the diagnostic technique for adhesions and perforations, double-contrast arthrotomography with fluoroscopy should be employed. The irregular surface of the eminences and the glenoid fossae shown by MR imaging and tomography are correlated with subchondral bone exposure by arthroscopy. Erosion of the condyles detected by MR imaging, tomography and rotational panoramic radiography is correlated with subchondral bone exposure detected by arthroscopy. (author). 69 refs

Es una enfermedad de etiología desconocida y poco frecuente. Puede definirse como un proceso benigno sinovial caracterizado por la formación de nódulos cartilaginosos (cuerpos libres. La CS afecta principalmente a grandes articulaciones sinoviales siendo poco común su aparición en la articulación temporomandibular. La sintomatología predominante es dolor, inflamación, limitación de los movimientos mandibulares, crepitación y laterodesviación mandibular. El diagnóstico se realiza mediante el estudio radiológico y artroscópico de la articulación. El tratamiento adecuado englobaría la extirpación completa de los cuerpos libres y de la sinovial afecta, bien mediante artroscopia o mediante cirugía abierta. Cuando está afectada la articulación temporomandibular las lesiones suelen estar localizadas en la cavidad articular, siendo rara su extensión extraarticular.

    Arthroscopic lysis and lavage surgery (AS) is an effective modality that can decrease pain and increase maximum interincisal opening (MIO) in patients with internal derangement (ID) of the temporomandibular joint (TMJ). However, some patients remain in pain or have limited mandibular range of motion despite AS. The purpose of this study was to determine the effectiveness, prevalence of adverse effects, and predictors of response to TMJ AS in patients with TMJ arthralgia and ID. A retrospective cohort study was conducted using data of patients who had undergone AS by a single surgeon (D.A.K.) from September 2010 to April 2015 in the Department of Oral and Maxillofacial Surgery at Massachusetts General Hospital (Boston, MA). Variables, including demographic data, medical history, and clinical presentation, were extracted and analyzed. Criteria for surgical success were defined as a postoperative MIO of at least 35 mm and a postoperative pain level no higher than 3 on an 11-point Likert-type numeric verbal pain rating scale. Appropriate descriptive and analytic statistics were computed and significance was set at a P value less than .05. Of the 247 participants, 226 (91.5%) were women. The mean age of the sample was 38 ± 15.4 years. Successful surgical outcome was achieved in 62.3% of patients. Based on logistic regression analysis, higher initial mean pain score and concurrent use of benzodiazepines were the only variables that predicted an unsuccessful surgical outcome (P < .001; P = .005). Adverse effects were reported by 13.4% of patients, the most common being postoperative increase in pain (13.4%), temporary malocclusion (1.2%), and temporary paresthesia in the preauricular region (0.4%). The results from this study indicate that in patients with ID of the TMJ unresponsive to noninvasive treatments, high initial pain scores and concurrent use of benzodiazepines are correlated with an unsuccessful outcome after AS.

    To determine whether shared genetic influences are responsible for the association between pain from temporomandibular disorders (TMD) and migraine headache. Data were obtained from 1,236 monozygotic and 570 dizygotic female twin pairs from the University of Washington Twin Registry. TMD pain was assessed with a question about persistent or recurrent pain in the jaw, temple, in front of the ear, or in the ear. The presence of migraine headache was determined by self-report of doctor-diagnosed migraine. Univariate and bivariate structural equation models estimated the components of variance attributable to genetic and environmental influences. The best fitting univariate models indicated that additive genetic effects contributed 27% of the variance in TMD pain (95% confidence interval = 15% to 38%) and 49% of the variance in migraine headache (95% confidence interval = 40% to 57%). The best-fitting bivariate model revealed that 12% of the genetic component of TMD pain is shared with migraine headache. These preliminary findings suggest that the association between TMD pain and migraine headache in women may be partially due to a modest shared genetic risk for both conditions. Future studies can focus on replicating these findings with symptom- and diagnosis-based instruments.

    Temporomandibular disorders are a form of musculoskeletal disorders, which reduce the function of stomatognathic system and they are related to some other diseases causing painful conditions and disorders of oral function. The aim of this paper is to describe a one year follow up clinical case of a female patient with comorbid multiple sclerosis and a relatively rare form of articular disc disorder. Primary clinical diagnostics encompassed manual methods of TMJ examination. Definite diagnosis included radiologic examination. Clinical hyperextensive condyle position was palpated bilaterally and subsequently confirmed by a functional panoramic radiograph of TMJ. The anterior displacement of disc with reduction was diagnosed by magnetic resonance and in the right joint there was a disc displacement upon excursive movement. From relevant literature, the relationship of a number of diseases that can be related to functional disorder of the orofacial system, such as multiple sclerosis, has been described from many aspects. Also, apart from the standard classification of one form of anterior displacement of the disc, made primarily by magnetic resonance, cases of disc displacement upon excursive mandibular movement can rarely be found in literature.

    Ten temporomandibular joints (TMJs) of 5 healthy volunteers and 19 TMJs of internal derangements in 16 patients with splint therapy were examined with MR imaging. T1-weighted images were obtained only in the closed mouth position, and gradient recalled acquisition in steady state (GRASS) images were obtained in active opening and closing phases, allowing a pseudodynamic display of TMJ movement. All patients received protrusive splint treatment. The usefulness of MR imaging to assess the efficacy of splint therapy was evaluated. Corrected disk position with the splint in place was clearly demonstrated in 9 TMJs, corresponding with elimination of reciprocal clicking. Ten other TMJs of anterior disk displacement without reduction showed uncorrected disk position by the splint. This information could confirm the therapeutic efficacy, or suggest other treatment alternatives. GRASS MR imaging can provide accurate and physiologic information about disk function in initial and follow-up assessment of protrusive splint therapy. (orig.).

    Full Text Available Occlusal splints are a standard method to treat disc displacement with reduction of the temporomandibular joint (TMJ. They can be classified into three major groups on the basis of function: stabilization splints, distraction splints (pivot, and anterior repositioning splints. The aim of this paper is to introduce a modified mandibular splint, the Kaohsuing Medical University splint, and its associated treatment regimen for management of disc displacement with reduction of the TMJ. The key points for fabrication of the KMU splint include the occlusal surface of the mandibular splint must be indented and average bite elevation 1.5 mm vertically. The patient should wear it 24 hours a day for the first 4 weeks, then wear it while eating and sleeping for the next 2 weeks, and wear it only while sleeping for the last 2 weeks. Patients must understand that the success of treatment depends on their compliance with the regimen.

    Full Text Available Temporomandibular joint (TMJ ankylosis as a complication of neonatal septic arthritis is rarely reported in the literature. We report two clinical cases of unilateral TMJ ankylosis occurring in paediatric patients subsequent to neonatal septic arthritis. The first case was a 15-month-old male infant who presented to the Sultan Qaboos University Hospital, Muscat, Oman, in May 2010. According to the published English scientific literature, he is the youngest person yet to be diagnosed with this condition. The second case was a five-year-old female who presented to the Al-Nahda Hospital, Muscat, Oman, in October 2011. Both cases presented with facial asymmetry and trismus. They subsequently underwent gap arthroplasty and interpositional temporalis muscle and fascia grafts which resulted in an immediate improvement in mouth opening. Postoperatively, the patients underwent active jaw physiotherapy which was initially successful. Both patients were followed up for a minimum of two years following their surgeries.

    Chondrosarcoma is the second most common sarcoma arising in the bone, but it rarely involves the temporomandibular joint (TMJ). To date, 30 cases of TMJ chondrosarcoma have been reported in the English literature, and the authors report an additional case arising from a cystic lesion in a 60-year-old female patient. The clinical and radiological diagnosis of the lesion was initially synovial cyst, and periodic check-ups were done after aspiration of the lesion. After three years, the patient perceived swelling of the lesion, and surgical excision was performed. The final diagnosis was grade I chondrosarcoma. When clinicians detect a cystic lesion in the radiographic imaging of the TMJ, chondrosarcoma should be included in the differential diagnosis. In addition, computed tomography (CT) as well as magnetic resonance imaging (MRI) is recommended for the accurate diagnosis and proper preoperative planning in TMJ chondrosarcoma.

    We examined the frequency of incidentally found or unexpected tumors discovered at the time of magnetic resonance imaging (MRI) examinations in the temporomandibular joint (TMJ) region for patients with suspicion of TMJ arthrosis. Five MR images (T1-weighted transverse scout image and proton density and T2-weighted oblique sagittal images at the open and closed mouth) were acquired. In 2776 MRI examinations of TMJ arthrosis, two tumors were discovered. They consisted of an adenoid cystic carcinoma in the deep portion of the parotid gland, and a malignant tumor extending from the infratemporal fossa to the parapharyngeal space. The rate of incidentally founded or unexpected tumors in TMJ examinations was low (0.072%), but the two tumors found were malignant tumors, and therefore, scout image should be carefully examined, not only used for positing the slice.

    The aim of this study was to investigate the effect of the autologous blood injection (ABI) for chronic recurrent temporomandibular joint (TMJ) dislocation using magnetic resonance imaging (MRI). ABI was applied to 14 patients who had chronic recurrent TMJ dislocation. MRIs of the patients were taken and compared before and one month after the injection. All of the patients had no dislocations of their TMJs on clinical examination one month after the injection. In the pre-injection, unilateral or bilateral TMJ dislocations were observed on MRIs in all patients. One month after the injection, TMJ dislocations were not observed in MRI evaluation of any patients. A significant structural change that caused by ABI was not observed. The procedure was easy to perform and it caused no foreign body reaction. However, it was unclear how the procedure prevented the dislocation.

    To evaluate the relationship between internal derangement and osteoarthrosis in the temporomandibular joint (TMJ) using magnetic resonance imaging (MRI). One hundred and six MR images of TMJs in 53 patients were evaluated. Disc displacements and osseous changes of the TMJs were assessed. Lateral and rotational disc displacements were also evaluated on coronal images. No significant differences in the frequency of osseous changes of the TMJs between disc displacement with reduction and disc displacement without reduction groups were found. The erosion of the condylar head and the sclerosis of the articular eminence were more frequent in the internal derangement group than in the no disc displacement group. The flattening was the most frequently observed osseous change of both the condylar head and articular eminence. The relationship between internal derangement and osteoarthrosis is obscure, but it is thought that both disorders adversely affect each other.

    Full Text Available Computed tomography (CT and magnetic resonance (MR image features of the temporomandibular joint (TMJ and associated structures in two mature dromedary camels were obtained with a third-generation equipment CT and a superconducting magnet RM at 1.5 Tesla. Images were acquired in sagittal and transverse planes. Medical imaging processing with imaging software was applied to obtain postprocessing CT and MR images. Relevant anatomic structures were identified and labelled. The resulting images provided excellent anatomic detail of the TMJ and associated structures. Annotated CT and MR images from this study are intended as an anatomical reference useful in the interpretation for clinical CT and MR imaging studies of the TMJ of the dromedary camels.

    To report the number and frequency of incidental findings (IFs) detected during magnetic resonance (MR) imaging screening of the temporomandibular joint (TMJ) and to define related diseases. Bilateral TMJ MR images in the sagittal and coronal sections, from 518 patients with TMJ symptoms were evaluated retrospectively. Patients who were diagnosed with IFs were sent for consultation and clarification of the findings. Patient age, gender, IFs, locations, and diseases were classified and noted.  Results: Seventy-eight (15%) patients were diagnosed with 117 IFs. Of them, 43 were diagnosed with a single IF, and 35 were diagnosed with more than one IF. The most frequent locations were paranasal sinuses and mastoid air cells. The most frequent diseases were inflammatory and cystic lesions.  Discussion: While examining TMJ MR images, it is important to check for evidence of IFs or pathologies that may have mimicked signs and symptoms of TMJ disorders.

    Congenital deformities of the mandibular ramus and of the temporo-mandibular joint are treated by surgery since the early 20th century. However, morphological and functional results are often disappointing, accounting for iterative operations. Today, a clear consensus concerning the type of intervention to be proposed, and at what age it should be carried out does not yet exist. For mild cases, "conventional" orthognathic or osteogenic distraction procedures seem to work well, especially if they are carried out at the end of growth. In severe cases, it is often necessary to proceed in several surgical steps, usually starting with a chondrocostal graft, especially when interceptive surgery, performed before the end of growth, is preferred in order to improve the patient's quality of life.

    Full Text Available We present a case involving a late diagnosis of chondroblastoma of the temporal skull base involving the temporomandibular joint (TMJ. Following an initial misdiagnosis and unsuccessful treatment over a period of 5 years, the patient was referred to our department for further evaluation and possible surgical intervention for occlusal abnormalities, trismus, clicking of the TMJ, and hearing impairment. Based on preoperative immunochemical studies showing positive reaction of multinucleated giant cells for S-100 protein, the final diagnosis was chondroblastoma. The surgical approach – postauricular incision and total parotidectomy, with complete removal of the temporal bone, including the TMJ via the extended middle fossa – was successful in preserving facial nerves and diminishing clinical manifestations. This study highlights a misdiagnosed case in an effort to underline the importance of medical examinations and accurate differential diagnosis in cases involving any tumor mass in the temporal bone.

    Radiographic findings of the upper and lower jaw bone of 20 adult patients with micrognathia, bird face, and juvenile rheumatoid arthritis are reported. In all patients a symmetrically underdeveloped mandible with the chin posteriorly positioned was found at cephalometry. Arthritic lesion of the temporomandibular joint, mostly symmetric, with limitation of movement and secondary arthrosis, was observed in all patients. Complete absence of the mandibular head was frequent (75%). The fossa was generally flat, probably due to growth disturbance of the tubercle. Abnormal anterior position of the mandibular head occurred in almost half of the patients. The degree of mandibular growth disturbance seemed to be correlated to the severity of the arthritis, indicating the arthritis to be a causal mechanism of micrognathia.

    Purpose. To evaluate the effectiveness of diagnostic and interventional radiological techniques for neoplastic lesions of the temporomandibular joint (TMJ). Material and methods. Modern diagnosis of the TMJ is based on the clinical use of conventional X-ray techniques, computed tomography (CT), magnetic resonance imaging (MRI) and interventional techniques like biopsies, vascular occlusion and ablation. Results. Conventional X-ray still forms the basic diagnostic procedure applied in open and closed mouth position. CT improves the diagnostic information and serves as the standard diagnostical instrument for cartaliganeous or osseous neoplastic lesions. MRI evaluates soft tissue infiltration in multiplanar techniques and high spatial resolution. Interventional vascular and ablative techniques improve the treatment of neoplastic disorders. (orig.)

    Thirty-nine temporomandibular joints (TMJ) from 20 patients with suspected internal derangements were imaged by a 1.5 T MR imager. The on-resonance binomial magnetization transfer contrast (MTC) pulse was applied to gradient echo images with a dual receiver coil (9 s/section). With the use of an opening device, a series of sequential images were obtained at increments of mouth opening and closing. The tissue signal intensities with (Ms) and without (Mo) MTC were measured and subjective image analysis was performed. Compared with the standard images, MTC technique provided selective signal suppression of disks. The average of Ms/Mo ratio of the disks (0.56) was lower than that of the retrodiskal pad (0.79) and of the effusion (0.89). With MTC technique, fluid conspicuity was superior to standard image. However, no significant superiority was found in disk definition subjectively. (orig.)

    Full Text Available The articular disc of the temporomandibular joint (TMJ is composed of fibrocartilage, and the extracellular matrix of this disc is composed mainly of collagen, glycosaminoglycan and proteoglycans. Research on the changes that occur in the composition of the articular disc of the TMJ is necessary for understanding the basis of the pathological process of internal derangement (ID, and a number of reports have been published in recent years on the application of refined histochemical techniques to investigate the structure and function of the TMJ. The direction of future TMJ disc studies should be towards obtaining more evidence to support previous results, and should hopefully be of practical use in terms of prevention and cure of ID.

    Many factors have been implicated in the development of bony ankylosis following trauma to the temporomandibular joint (TMJ) or ankylosis that recurs after surgical treatment for the condition. Although many reports have been published, to our knowledge very little has been written about the pathogenesis of the process and there are few scientific studies. Over the last 70 years various treatments have been described. Different methods have been used with perceived favourable outcomes although recurrence remains a problem in many cases, and ankylosis presents a major therapeutic challenge. We present a critical review of published papers and discuss the various hypotheses regarding the pathogenesis of the condition.

    We compared the diagnostic reliability of 3.0-T magnetic resonance imaging (MRI) for detection of osseous abnormalities of the temporomandibular joint (TMJ) with that of the gold standard, cone-beam computed tomography (CBCT). Fifty-six TMJs were imaged with CBCT and MRI, and images of condyles and fossae were independently assessed for the presence of osseous abnormalities. The accuracy, sensitivity, and specificity of 3.0-T MRI were 0.88, 1.0, and 0.73, respectively, in condyle evaluation and 0.91, 0.75, and 0.95 in fossa evaluation. The McNemar test showed no significant difference (P > 0.05) between MRI and CBCT in the evaluation of osseous abnormalities in condyles and fossae. The present results indicate that 3.0-T MRI is equal to CBCT in the diagnostic evaluation of osseous abnormalities of the mandibular condyle.

    The morphological changes of the mandibular condyle in patients with temporomandibular joint disorder were studied. The subjects were 420 patients (103 males and 317 females, 8 to 80 years of age, mean age 39.8 years) who were clinically diagnosed as temporomandibular joint disorder. MR imaging was performed with a GE-Signa 1.5 Tesla MR imaging system using the body coil as a transmitter and 3-inch bilateral surface coils. The patients were examined by a multiplanar gradient echo technique in a closed-loop cine fashion on both sagittal and coronal planes. The results obtained were as follows: 1) Morphological changes of the mandibular condyle were detected in 47.0% of the patients. The predominant morphological changes were then formation of osteophyte and marginal proliferation (65.8%). 2) The incidence of morphological changes in the mandubular condyle did not show any significant difference between male and female, and tended to be higher in patients over 40 years of age, and the incidence in patients under 20 years of age was lower, compared to that in patients from 20 to 39 years of age. 3) The incidence of morphological changes in patients with anterior disk displacement without reduction was higher than in those with anterior disk displacement with reduction (P<0.001). The incidence of morphological changes in patients with rotational disk displacement was higher than in those with medial disk displacement (P<0.001). 4) The anterior translation of mandibular condyle was influenced more by anterior disk displacement rather than by morphological changes. From these results. it is suggested that simultaneous bilateral condyle pseudodynamic MR imaging was useful in the diagnosis of internal derangement, evaluation of morphological changes and assessment of motional abnormality of the condyle.

    To investigate the histopathological changes in the temporomandibular joint in streptozotocin-induced diabetic rat following irradiation. Sprague-Dawley rats weighing about 250 gm were divided into three groups: control, diabetic, and diabetic-irradiated groups. Diabetes mellitus was induced in the rats by injecting streptozotocin. Rats in the control group were injected with citrate buffer only. After 5 days, the head and neck region of the rats in diabetic-irradiated group were irradiated with single absorbed dose of 10 Gy. The rats were killed at 1, 3, 7, 14, 21, and 28 days after irradiation. The specimen including the temporomandibular joint were sectioned and observed using a histopathological method. In the diabetic group, severe bone resorption in the mandibular condyle was observed throughout the period of experiment. Necrosis of bone marrow and trabeculae was observed at 28 days after diabetic state. Atrophy and fibrosis in the retrodiscal tissue was gradually progressed during the time of the experiment. In the diabetic-irradiated group, severe bone resorption in the mandibular condyle was observed during the early experimental phases, but regeneration of bone marrow was initiated at 14 days after diabetic state and irradiation. Also, calcification of abnormal trabeculae was observed at 28 days after diabetic state and irradiation. The retrodiscal tissue was degenerated in the early experimental phases, but it had been gradually regenerated during the experimental time. This experiment suggests that bone resorption and degeneration in the mandibular condyle are caused by the induction of diabetes, and abnormal bone formation is induced after irradiation in diabetic state.

    Full Text Available Abstract Background Temporomandibular disorders (TMDs are characterized by persistent orofacial pain and have diverse etiologic factors that are not well understood. It is thought that central sensitization leads to neuronal hyperexcitability and contributes to hyperalgesia and spontaneous pain. Nonsteroidal anti-inflammatory drugs (NSAIDs are currently the first choice of drug to relieve TMD pain. NSAIDS were shown to exhibit anticonvulsant properties and suppress cortical neuron activities by enhancing neuronal voltage-gated potassium KCNQ/Kv7 channels (M-current, suggesting that specific activation of M-current might be beneficial for TMD pain. Results In this study, we selected a new anticonvulsant drug retigabine that specifically activates M-current, and investigated the effect of retigabine on inflammation of the temporomandibular joint (TMJ induced by complete Freund's adjuvant (CFA in rats. The results show that the head withdrawal threshold for escape from mechanical stimulation applied to facial skin over the TMJ in inflamed rats was significantly lower than that in control rats. Administration of centrally acting M-channel opener retigabine (2.5 and 7.5 mg/kg can dose-dependently raise the head withdrawal threshold of mechanical allodynia, and this analgesic effect can be reversed by the specific KCNQ channel blocker XE991 (3 mg/kg. Food intake is known to be negatively associated with TMJ inflammation. Food intake was increased significantly by the administration of retigabine (2.5 and 7.5 mg/kg, and this effect was reversed by XE991 (3 mg/kg. Furthermore, intracerebralventricular injection of retigabine further confirmed the analgesic effect of central retigabine on inflammatory TMJ. Conclusions Our findings indicate that central sensitization is involved in inflammatory TMJ pain and pharmacological intervention for controlling central hyperexcitability by activation of neuronal KCNQ/M-channels may have therapeutic potential for

    Full Text Available Abstract This cross-sectional study was designed to evaluate the effect of sleep bruxism, awake bruxism and parafunctional habits, both separately and cumulatively, on the likelihood of adolescents to present painful TMD. The study was conducted on a sample of 1,094 adolescents (aged 12-14. The presence of painful TMD was assessed using the Research Diagnostic Criteria for Temporomandibular Disorders, Axis I. Data on sleep bruxism, awake bruxism and parafunctional habits (nail/pen/pencil/lip/cheek biting, resting one’s head on one’s hand, and gum chewing were researched by self-report. After adjusting for potential demographic confounders using logistic regression, each of the predictor variables (sleep bruxism, awake bruxism and parafunctional habits was significantly associated with painful TMD. In addition, the odds for painful TMD were higher in the concomitant presence of two (OR=4.6, [95%CI=2.06, 10.37] or three predictor (OR=13.7, [95%CI=5.72, 32.96] variables. These findings indicate that the presence of concomitant muscle activities during sleep and awake bruxism and parafunctional habits increases the likelihood almost linearly of adolescents to present painful TMD.

Two questionnaires were applied to them: the Fonseca clinical questionnaire and one on headache. Data were statistically analysed and significance level set at p<0.05. Results showed a higher prevalence of TMD among female individuals with headache, but a direct relationship between headache and degree of temporomandibular joint dysfunction could not be found.

    The objective of this study was to describe the arthroscopic findings of chondromalacia and its relation with the internal derangement of the temporomandibular joint (TMJ). A total of 161 patients (299 TMJs) who underwent arthroscopy were included in the study. The TMJs were evaluated objectively under arthroscopic vision, and 4 groups of patients were established according to the degree of involvement, degree I, II, III and IV. Statistical analyses were conducted using logistic regression models (P chondromalacia and 66 (41%) in 88 joints exhibited some degree of chondromalacia (44 patients unilaterally and 22 bilaterally). Of the 88 joints with chondromalacia, 14 (15.9%) had chondromalacia degree I, 12 (13.6%) chondromalacia degree II, 20 (22.7%) chondromalacia degree III and 42 (47.7%) chondromalacia degree IV. The chondromalacia was more significantly found in patients with ADDwR and discal perforation (P Chondromalacia degree IV was a significant finding in cases of ADDwoR (P = 0.000619). Chondromalacia of the TMJ is a common finding in patients with internal derangement even at the early stages. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery.

    Full Text Available Synovial inflammation (synovitis frequently accompanies intracapsular pathologic conditions of the temporomandibular joint (TMJ such as internal derangement (ID and/or osteoarthritis (OA, and is suggested to be associated with symptom severity. To identify the putative factors associated with synovitis, we investigated interleukin (IL-1β- and/or tumor necrosis factor (TNF-α-responsive genes of fibroblast-like synoviocytes (FLS from patients with ID and/or OA of TMJ using microarray analysis. In this review, we first summarize the FLS of TMJ and the signaling pathways of IL-1β and TNF-α. Next, we show the up-regulated genes in FLS after stimulation with IL-1β or TNF-α, and summarize the gene functions based on recent studies. Among the top 10 up-regulated factors, molecules such as IL-6 and cycrooxygense-2 have been well characterized and investigated in the inflammatory responses and tissue destruction associated with joint diseases such as RA and OA, but the roles of some molecules remain unclear. The FLS reaction can lead to the synthesis and release of a wide variety of inflammatory mediators. Some of these mediators are detected in joint tissues and synovial fluids under intracapsular pathologic conditions, and may represent potential targets for therapeutic interventions in ID and/or OA of TMJ.

  7. BMPRIA mediated signaling is essential for temporomandibular joint development in mice.

    Full Text Available The central importance of BMP signaling in the development and homeostasis of synovial joint of appendicular skeleton has been well documented, but its role in the development of temporomandibular joint (TMJ, also classified as a synovial joint, remains completely unknown. In this study, we investigated the function of BMPRIA mediated signaling in TMJ development in mice by transgenic loss-of- and gain-of-function approaches. We found that BMPRIA is expressed in the cranial neural crest (CNC-derived developing condyle and glenoid fossa, major components of TMJ, as well as the interzone mesenchymal cells. Wnt1-Cre mediated tissue specific inactivation of BmprIa in CNC lineage led to defective TMJ development, including failure of articular disc separation from a hypoplastic condyle, persistence of interzone cells, and failed formation of a functional fibrocartilage layer on the articular surface of the glenoid fossa and condyle, which could be at least partially attributed to the down-regulation of Ihh in the developing condyle and inhibition of apoptosis in the interzone. On the other hand, augmented BMPRIA signaling by Wnt1-Cre driven expression of a constitutively active form of BmprIa (caBmprIa inhibited osteogenesis of the glenoid fossa and converted the condylar primordium from secondary cartilage to primary cartilage associated with ectopic activation of Smad-dependent pathway but inhibition of JNK pathway, leading to TMJ agenesis. Our results present unambiguous evidence for an essential role of finely tuned BMPRIA mediated signaling in TMJ development.

    To determine abnormalities of the temporomandibular joint (TMJ) associated with cervical extension-flexion injury (whiplash) with use of MR imaging. Sixteen patients (32 joints) with TMJ syndrome-related symptoms after whiplash injuries from automobile accidents were evaluated by MR imaging. None of the patients had direct trauma to the jaw, mouth, or face. T1-weighted closed- and opened-mouth views were obtained in the sagittal plane, and closed-mouth views were obtained in the coronal plane. T2-weighted closed-mouth views obtained in the sagittal plane were also obtained to optimize identification of fluid/edema. Fourteen (87%) of 16 patients had one or more of the following TMJ abnormalities: 11 (34%) had anterior displacement of the disk with reduction and 2 (6%) had anterior displacement of the disk without reduction. On T2-weighted images, 17 TMJs (53%) had joint fluid and 5 (16%) had fluid localized to the capsule and/or pterygoid muscle. These data demonstrated a high incidence of TMJ abnormalities related to whiplash injury. The predominant finding was associated fluid/edema, suggesting that T2-weighted images are particularly useful for the evaluation of patients who present with whiplash injury

    The temporomandibular joint and its associated musculature are described in a neonate gray whale (Eschrichtius robustus) and serve as the basis for direct anatomical comparisons with the temporomandibular region in other clades of baleen whales (Mysticeti). Members of the right whale/bowhead whale clade (Balaenidae) are known to possess a synovial lower jaw joint, while members of the rorqual clade (Balaenopteridae) have a nonsynovial temporomandibular joint characterized by a highly flexible fibrocartilaginous pad and no joint capsule. In contrast, the gray whale possesses a modified temporomandibular joint (intermediate condition), with a vestigial joint cavity lacking a fibrous capsule, synovial membrane, and articular disk. In addition, the presence of a rudimentary fibrocartilaginous pad appears to be homologous to that seen in balaenopterid mysticetes. The intrinsic temporomandibular musculature in the gray whale was found to include a multibellied superficial masseter and a single-bellied deep masseter. The digastric and internal pterygoid muscles in E. robustus are enlarged relative to the condition documented in species of Balaenoptera. A relatively complex insertion of the temporalis muscle on the dentary is documented in the gray whale and the low, knob-like process on the gray whale dentary is determined to be homologous with the prominent coronoid process of rorquals. Comparison with the anatomy of the temporomandibular musculature in rorquals reveals an increased importance of alpha rotation of the dentary in the gray whale. This difference in muscular morphology and lines of muscle action is interpreted as representing adaptations for suction feeding. © 2015 Wiley Periodicals, Inc.

    Full Text Available Aim. To estimate the prevalence of painful temporomandibular disorders (TMD-P among adolescents and to investigate correlations with health, environment, and lifestyle factors. Methods. For this cross-sectional case-control study, 562 patients were consecutively recruited at their yearly revision control from four dental clinics in Rogaland County, Norway. Patients completed a questionnaire on general health, socioeconomics, demographics, and lifestyle factors. Responses to two screening questions identified patients with TMD-P, who then underwent clinical examination to verify the TMD diagnosis. Pain intensity was assessed on a visual analogue scale. Patients without TMD-P constituted the control group and were not clinically examined. Results. 7% experienced TMD-P. The female-to-male ratio is 3:1; median age is 17 years. Patients at urban clinics had higher prevalence compared with those at rural clinics. TMD-P patients had headache and severe menstrual pain compared to controls. They were more likely to live with divorced/single parents and less likely to have regular physical activity. Myalgia was present in 21 patients with TMD-P, arthralgia in nine, and myalgia and arthralgia in nine. Females had higher pain intensity than males. Conclusions. A low prevalence of TMD-P was shown but was comparable to other studies. Sex, health, lifestyle, and environment factors were associated with TMD-P.

    2018-03-12

    The aim of this study was to assess the influence of protraction facemask (PFM) on temporomandibular joint (TMJ) of skeletal Class III malocclusion patients. Literature searches were carried out electronically in five English and three Chinese databases (Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, PubMed, Embase, MEDLINE (via Ovid), Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and VIP Database). The date of the most recent search was 22 March 2017. Randomized controlled trials, controlled clinical trials, cohort studies, and before-after studies comparing the effect of PFM and other treatments on TMJ were included. The data were collected and extracted by three authors. The risk of bias in the RCTs was assessed in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. For the nonrandomized studies, the risk of bias was judged with Newcastle-Ottawa Scale. For the 261 articles identified, 13 studies with 522 participants were included for the final qualitative analysis. Three studies were graded as high value of evidence, while seven studies and the other three studies were graded as moderate value and low value respectively. According to the available evidence, PFM contributed to the significant increase of CondAx-SBL and the significant decrease of CondAx-ML. Thin-plate spline (TPS) analysis showed a horizontal compression in condyles. Condyles tended to move superiorly and posteriorly. Concerning the occurrence of temporomandibular disorders (TMD), PFM was not involved in aggravating TMJ symptoms and signs. Clinical evidence suggests that PFM might contribute to the morphologic adaptation of TMJs and displacement of condyles, and PFM may well be not a risk factor for the development of TMD.

    The aim was to investigate the association between temporomandibular disorders (TMD) and overall muscle tenderness, depressive symptoms, sleep difficulties, headache frequency and related symptoms in children with primary headache in comparison with controls. Based on an unselected population sample of 1135 Finnish schoolchildren classified according to the type of headache at age 12, altogether 297 children aged 13-14 from different headache groups and healthy controls were randomly selected for an interview and clinical examinations. Children with migraine had more TMD signs than children with nonmigrainous headaches or healthy controls. High TMD total scores were associated with palpation tenderness in other parts of the body and with frequent headache attacks. We conclude that children with overall headache, migraine in particular, and high total TMD scores showed an increased overall tenderness to muscle palpation and multiply manifested hypersensitivity pain.

    (1) To examine the heritability of TMD pain and of neck pain; and (2) to estimate the potential overlap in genetic and environmental factors influencing TMD pain and neck pain. Data from 2,238 adult female twins who completed a survey on TMD pain and neck pain were analyzed. The total variance of TMD pain and neck pain was decomposed into variance attributable to additive genetic effects and nonshared environmental effects. Bivariate structural equation modeling was applied to estimate trait-specific and genetic effects shared between traits. The prevalence of TMD pain and neck pain was 8.6% and 46.8%, respectively, while 6.7% of the twins reported both TMD pain and neck pain. The phenotypic correlation between TMD pain and neck pain, based on a liability threshold model, was 0.43 (95% confidence interval [CI] 0.34 to 0.51). The heritability for TMD was 0.35 (0.17 to 0.51), and for neck pain was 0.33 (0.23 to 0.43). The genetic correlation between TMD pain and neck pain was 0.64 (0.35 to 1.00), and the environmental correlation was 0.32 (0.14 to 0.48). This study shows that variation in TMD pain and neck pain can in part be attributed to genes. The comorbidity between them is partly explained by genes that influence both traits and partly by the same environmental factors.

  15. Maresin 1 Inhibits TRPV1 in Temporomandibular Joint-Related Trigeminal Nociceptive Neurons and TMJ Inflammation-Induced Synaptic Plasticity in the Trigeminal Nucleus

    Full Text Available In the trigeminal system, disruption of acute resolution processing may lead to uncontrolled inflammation and chronic pain associated with the temporomandibular joint (TMJ. Currently, there are no effective treatments for TMJ pain. Recently, it has been recognized that maresin 1, a newly identified macrophage-derived mediator of inflammation resolution, is a potent analgesic for somatic inflammatory pain without noticeable side effects in mice and a potent endogenous inhibitor of transient receptor potential vanilloid 1 (TRPV1 in the somatic system. However, the molecular mechanisms underlying the analgesic actions of maresin 1 on TMJ pain are unclear in the trigeminal system. Here, by performing TMJ injection of a retrograde labeling tracer DiI (a fluorescent dye, I showed that maresin 1 potently inhibits capsaicin-induced TRPV1 currents and neuronal activity via Gαi-coupled G-protein coupled receptors in DiI-labeled trigeminal nociceptive neurons. Further, maresin 1 blocked TRPV1 agonist-evoked increases in spontaneous excitatory postsynaptic current frequency and abolished TMJ inflammation-induced synaptic plasticity in the trigeminal nucleus. These results demonstrate the potent actions of maresin 1 in regulating TRPV1 in the trigeminal system. Thus, maresin 1 may serve as a novel endogenous inhibitor for treating TMJ-inflammatory pain in the orofacial region.

    Modern health care in the field of Medicine, Dentistry and Nursing is grounded in fundamental philosophy and epistemology of translational science. Recently in the U.S major national initiatives have been implemented in the hope of closing the gaps that sometimes exist between the two fundamental components of translational science, the translational research and translational effectiveness. Subsequent to these initiatives, many improvements have been made; however, important bioethical issues and limitations do still exist that need to be addressed. One such issue is the stakeholder engagement and its assessment and validation. Federal, state and local organizations such as PCORI and AHRQ concur that the key to a better understanding of the relationship between translational research and translational effectiveness is the assessment of the extent to which stakeholders are actively engaged in the translational process of healthcare. The stakeholder engagement analysis identifies who the stakeholders are, maps their contribution and involvement, evaluates their priorities and opinions, and accesses their current knowledge base. This analysis however requires conceptualization and validation from the bioethics standpoint. Here, we examine the bioethical dilemma of stakeholder engagement analysis in the context of the person-environment fit (PE-fit) theoretical model. This model is an approach to quantifying stakeholder engagement analysis for the design of patient-targeted interventions. In our previous studies of Alzheimer patients, we have developed, validated and used a simple instrument based on the PE-fit model that can be adapted and utilized in a much less studied pathology as a clinical model that has a wide range of symptoms and manifestations, the temporomandibular joint disorders (TMD). The temporomandibular joint (TMJ) is the jaw joint endowed with sensory and motor innervations that project from within the central nervous system and its dysfunction can

    Temporomandibular Joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of re-ankylosis. Interpositional gap arthroplasty is one of the modalities for its management. A range of inter-positional materials have been used to avert recurrence after gap arthroplasty in TMJ anky...

    The aim of the present study was to assess the associations between different types of perceived stress, pain and work performance among non-patients with clinical signs of muscle pain in the head/neck region. One-fifth (n = 241) of the 1339 media employees who had participated in a previous survey (Ahlberg J. et al., J Psychosom Res 2002; 53: 1077-1081) were randomly selected for standardized clinical examinations. Altogether 49% (n = 118) of these subjects had clinical signs of temporomandibular and/or neck muscle pain and were enrolled in the present study. The mean age of the study sample was 46.9 years (s.d. 6.6) and the female to male distribution 2:1. Of the 118 employees 46.5% reported that the pain problem interfered with their ability to work. Perceived ability to work was not significantly associated with age, gender or work positions. According to logistic regression, reduced work performance was significantly positively associated with continuous pain [odds ratio (OR) 4.38; 95% CI 1.21-15.7], level of perceived pain severity (OR 1.30; 95% CI 1.04-1.63), and health stress (OR 2.08; 95% CI 1.22-3.54). The results of this study indicated an association between specific self-reported stress regarding health and work issues, pain and work performance. From a preventive perspective this indicates a need for increased awareness about these associations on not only individual level but also at the organizational level and in health care.

    Objective of the study was to evaluate the clinical status of the masticatory system in young adults with full permanent dentition and no stomatognathic system complaints. The study involved 186 randomly selected people with full dental arches with normal occlusal conditions corresponding to Angle's Class I aged 18 - 21 years with an average age of 19 years. Subjects were clinically examined and temporomandibular joint (TMJ) vibrations were recorded during open-wide and close movements using BioJVA. Then, patients were categorized into groups according to Piper's classification system. The TMJs of the subjects were categorized according to the values of the vibration energy and the Piper protocol. This detected 33.4% of the joints with loosened ligaments, subluxation in 8.28%, initial signs of disc dysfunction in 5.08% and disc displacement without locking in 1.6 %. Median frequency differed significantly (p vibrations. However, a subset of people manifested higher vibrations that may indicate an early stage of TMJ dysfunction. Median Frequency was an important parameter for detecting initial symptoms of TMJ dysfunction. Peak Frequency was an important characteristic parameter for detecting TMJ subluxation.

    In the field of orthopedics, CT arthrography has been utilized for the shoulder and the knee joints diagnosis. In this study, CT arthrography was applied to the temporomandibular joint (TMJ) and the usefulness of this method was evaluated experimentally and clinically. In the experimental study, CT, CT arthrography and arthrotomogtaphy were compared each other with serial section from human autopsy specimen. It was confirmed that arthrography was indispensable for diagnosis of the location and configuration of the articular disk. In the sagittal section, CT arthrography was almost equal to arthrotomography. But in the coronal section, CT arthrography proved to be advantageous to arthrotomography, because there were various blur images on the arthrotomographic images from the complex bony structures of the skull. In the clinical study, coronal CT arthrography was applied for the patients with internal derangements of the TMJ. The mesio-lateral displacement of the disk (62%), perforation of the attachment (23%), and the intra-articular adhesion (70%) could be diagnosed. BY CT arthrography, the mesio-lateral displacement of the disk was more clearly diagnosed and the intra-articular adhesions were proved with higher rate than by the arthrotomography. From this study, it was concluded that CT arthrography has an important role in diagnosis of the TMJ soft tissue. (author) 51 refs.

    Published descriptions of nonseptic arthritis of the equine temporomandibular joint (TMJ) are rare and large studies investigating variations in the TMJ for asymptomatic horses are lacking. The objectives of this cross-sectional, retrospective, multi-institutional study were to describe anatomical variations in the TMJ detected using computed tomography (CT) in an equid population asymptomatic for TMJ disease and determine whether these variations were associated with patient signalment, reason for CT examination, or CT slice width. Medical records at eight hospitals were searched for horses that had head/neck CT scans and no clinical signs of TMJ disease. Age, breed, sex, clinical presentation, and CT slice width data were recorded. Alterations in CT contour and density of the mandibular condyles, mandibular fossae, and TMJ intra-articular discs were described for each horse. Generalized logistic regression was used to test associations between anatomical variations and horse age. A total of 1018 horses were sampled. Anatomical variations were found in TMJ CT images for 40% of horses and 29% of joints. These were dichotomous with regard to age. Horses horses commonly had spherical hypodensities within the mandibular condyles consistent with bone cysts; and hyperdense regions of the intra-articular disc consistent with dystrophic mineralization. Findings indicated that TMJ anatomic variations were common in CT images of younger and older horses asymptomatic for TMJ disease. Future studies are needed to more definitively characterize these CT variations using gross pathology and histopathology. © 2016 American College of Veterinary Radiology.

    This study determines the value of three-dimensional (3-D) sonography for the assessment of disk dislocation of the temporomandibular joint (TMJ). Sixty-eight patients (i.e.,136 TMJ) with clinical dysfunction were examined by 272 sonographic 3-D scans. An 8- to 12.5-MHz transducer, angulated by step-motor, was used after picking a volume box on 2-D scan; magnetic resonance imaging followed immediately. Every TMJ was scrutinized in closed- and open-mouth position for normal or dislocated disk position. Fifty-three patients had complete data sets, i.e., 106 TMJ, 212 examinations. Sonographic examination took 5 min, with 74% specificity (62% closed-mouth; 85% open-mouth); sensitivity 53% (62/43%); accuracy 70% (62/77%); positive predictive value 49% (57/41%); and negative predictive value 77% (67/86%). This study encourages more research on the diagnostic capacity of 3-D TMJ sonography, with the advantage of multidimensional joint visualization. Although fair in specificity and negative predictive value, sensitivity and accuracy may ameliorate with future higher-sound frequency, real-time 3-D viewing and automated image analysis.

    Magnetic Resonance Images (MRI) of the temporomandibular joint (TMJ) are usually performed to study the opening/closing movements of the mandible and have up to now been pseudodynamic step-by-step images simulating condylar motion by post-processing reconstruction. The aim of this study was: 1. to optimize a TMJ cine-imaging method to give a better clinical result than the step-by-step methods; 2. to develop an ultra-fast MRI Gradient Echo (GE) sequence for this purpose; and 3. to analyze condylar movements in the sagittal, coronal and para-axial planes during border mandibular displacements and chewing. Both TM joints were studied in six asymptomatic volunteers. The method involved a compromise between in-plane resolution, slice thickness, signal-to-noise ratio and time resolution. Routine clinical use was found to be a GE pulse sequence providing three images per second with an isometric voxel resolution of approximately two millimeters in ridge. This did not allow visualization of the disk. Using this sequence enabled real and simultaneous condylar displacement observation in the three planes of space and therefore contributed to a better functional diagnosis of pathologic TMJ motions.

    To investigate whether pain-related temporomandibular disorders (TMD) are the product of an interaction between psychological factors and self-reported bruxism activities. Patients referred to a specialized clinic for complaints of orofacial pain and dysfunction completed a digital questionnaire prior to the first clinical visit. The patient sample was then split into a case group consisting of 268 patients diagnosed with TMD pain according to the Diagnostic Criteria for Temporomandibular Disorders (85.8% women; mean ± standard deviation [SD] age = 40.1 ± 14.5 years) and a control group consisting of 254 patients without any pain in the orofacial area (50.8% women; 46.9 ± 13.6 years). The possible moderating roles of six psychological factors (depression, somatic symptoms, anxiety, stress, optimism, and prior psychological treatment) on the relationship between self-reported bruxism and the clinical presence of TMD pain were examined. Patients with TMD pain reported significantly more bruxism than patients without any report of orofacial pain. Furthermore, bruxism intensity was associated with a variety of psychological factors; however, there were no significant interactions between any of the psychological factors and bruxism with respect to the clinical presence of TMD pain. These findings do not support the view that the effect of bruxism on TMD pain is stronger in patients who experience higher levels of psychological distress compared to those with lower levels of distress.

    Parafunctional habits such as clenching or grinding (bruxism) during daytime and at night are considered to have a great impact on the etiopathogenesis of temporomandibular disorders (TMD). However, the size of the effect and how daytime activities interact with nocturnal activities is not yet clear. The aim of this study was to assess the association of TMD pain with both awake and sleep bruxism in adults. In this case-control study, data of a consecutive sample of 733 TMD patients (cases; mean age ± SD: 41.4 ± 16.3 years; 82% women) with at least one pain-related TMD diagnosis according to the German version of the Research Diagnostic Criteria for TMD (RDC/TMD) and of a community-based probability sample of 890 subjects (controls; mean age ± SD: 40.4 ± 11.8 years; 57% female) without TMD were evaluated. Clenching or grinding while awake and/or asleep was assessed with self-reports. Association of TMD pain with awake and sleep bruxism was analyzed using multiple logistic regression analyses and controlled for potential confounders. Odds ratios (OR) with corresponding 95% confidence intervals (CI) were calculated. While 11.2% of the controls reported clenching or grinding while awake, this proportion was significantly higher in TMD patients (33.9%; p bruxism (OR 1.8; CI 1.4-2.4). However, risk for TMD pain substantially increased in cases of simultaneous presence of awake and sleep bruxism (OR 7.7; CI 5.4-11.1). When occurring separately, awake and sleep bruxism are significant risk factors for TMD pain. In case of simultaneous presence, the risk for TMD pain is even higher.

    Full Text Available Hypermobility is defined as an abnormally increased range of motion of a joint resulting from the excessive laxity of the soft tissues. This paper is focused on this commonly forgotten cause of several morbidities. The etiology of hypermobility is not very well known. One decade ago, joint hypermobility syndrome was considered as a benign condition, but now it is recognized as a significant contributor to chronic musculoskeletal pain, besides impacting on other organs. Patients with joint hypermobility syndrome often have diffuse, chronic complaints that are inconsistent with the musculoskeletal system. Chronic pain may cause loss of proprioception and so increased sensitivity to microtrauma, premature osteoarthritis de- velopment, soft tissue problems, psychosocial disorders, and neurophysiological deficiencies. Osteoarthritis, pes planus, mechanical low back pain, and soft tissue rheumatisms are frequent musculoskeletal findings as well as subluxations, thoracic outlet syndrome, rectal and uterine prolapses, hernias, and stress incontinence. Joint hypermobility syndrome's treatment is not easy, and nonsteroidal anti-inflammatory drugs are not usually effective or adequate. Proprioceptive and strengthening exercises have been reported to have supportive and therapeutic effects, but we have limited data on this issue. Joint hypermobility syndrome must be accepted as a multisystem connective tissue disorder rather than just joint laxities. As a result; clinicians must be aware of complexities of connective tissue disorders and comorbidities. [Arch Clin Exp Surg 2016; 5(2.000: 105-112

    Full Text Available Abstract Background Temporomandibular joint disorders (TMJD are multifactor, complex clinical problems affecting approximately 60–70% of the general population, with considerable controversy about the most effective treatment. For example, reports claim success rates of 70% and 83% for non-surgical and surgical treatment, whereas other reports claim success rates of 40% to 70% for self-improvement without treatment. Therefore, the purpose of this study was to (1 identify systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment, (2 evaluate their methodological quality, and (3 evaluate the evidence grade within the systematic reviews. Methods A search strategy was developed and implemented for MEDLINE, Cochrane Library, LILACS, and Brazilian Dentistry Bibliography databases. Inclusion criteria were: systematic reviews (± meta-analysis comparing surgical and non-surgical TMJD treatment, published in English, Spanish, Portuguese, Italian, or German between the years 1966 and 2007(up to July. Exclusion criteria were: in vitro or animal studies; narrative reviews or editorials or editorial letters; and articles published in other languages. Two investigators independently selected and evaluated systematic reviews. Three different instruments (AMSTAR, OQAQ and CASP were used to evaluate methodological quality, and the results averaged. The GRADE instrument was used to evaluate the evidence grade within the reviews. Results The search strategy identified 211 reports; of which 2 were systematic reviews meeting inclusion criteria. The first review met 23.5 ± 6.0% and the second met 77.5 ± 12.8% of the methodological quality criteria (mean ± sd. In these systematic reviews between 9 and 15% of the trials were graded as high quality, and 2 and 8% of the total number of patients were involved in these studies. Conclusion The results indicate that in spite of the widespread impact of TMJD, and the multitude of

    Background: Temporomandibular joints (TMJ) are frequently involved in children with juvenile idiopathic arthritis (JIA), and gadolinium-enhanced magnetic resonance imaging (MRI) is the only modality for an early diagnosis. However, only very few data exist on the appearance of contrast-enhanced MRI of normal juvenile TMJ. Purpose: To define the spectrum of normal MRI findings of juvenile TMJ, and to assess a possible overlap with findings typical for active synovitis in JIA. Material and Methods: 96 children (192 TMJ), 51 boys and 45 girls with a median age of 7.8 years (range 3-13 years), underwent a head MRI. The presence of autoimmune disease, including JIA, was excluded via chart history, available laboratory findings, and the absence of known typical pathological MRI changes (degree of synovial enhancement, hyperintense signal on T2-weighted images in the synovia or bone marrow, and morphologic changes of the mandibular condyle) of the TMJ affected by JIA. Results: In 90 (94%) children, the TMJ showed no MRI abnormalities compatible with arthritis. In three children (3%), the only abnormal MRI finding was a small bilateral joint effusion. A further three children (3%) had a mild synovial enhancement seen on both axial and coronal MR planes in one child and only in the axial plane in the other two children. Signal hyperintensity on T2-weighted images and other corresponding characteristics of TMJ inflammation were lacking in all these six patients. Conclusion: The vast majority of juvenile TMJ in non-rheumatic children shows no MRI abnormalities. Exceptions, including a discrete enhancement of the synovial membrane (3%) or small joint effusions (3%), can occur in a minority of patients, but none of them are accompanied by other signs of inflammation or morphological changes of the TMJ

    Personalized prosthetic joint replacements have important applications in cases of complex bone and joint conditions where the shape and size of off-the-shelf components may not be adequate. The objective of this study was to design, test and fabricate a personalized 3D-printed prosthesis for a patient requiring total joint replacement surgery of the temporomandibular joint (TMJ). The new 'Melbourne' prosthetic TMJ design featured a condylar component sized specifically to the patient and fixation screw positions that avoid potential intra-operative damage to the mandibular nerve. The Melbourne prosthetic TMJ was developed for a 58-year-old female recipient with end-stage osteoarthritis of the TMJ. The load response of the prosthesis during chewing and a maximum-force bite was quantified using a personalized musculoskeletal model of the patient's masticatory system developed using medical images. The simulations were then repeated after implantation of the Biomet Microfixation prosthetic TMJ, an established stock device. The maximum condylar stresses, screw stress and mandibular stress at the screw-bone interface were lower in the Melbourne prosthetic TMJ (259.6MPa, 312.9MPa and 198.4MPa, respectively) than those in the Biomet Microfixation device (284.0MPa, 416.0MPa and 262.2MPa, respectively) during the maximum-force bite, with similar trends also observed during the chewing bite. After trialing surgical placement and evaluating prosthetic TMJ stability using cadaveric specimens, the prosthesis was fabricated using 3D printing, sterilized, and implanted into the female recipient. Six months post-operatively, the prosthesis recipient had a normal jaw opening distance (40.0 mm), with no complications identified. The new design features and immediate load response of the Melbourne prosthetic TMJ suggests that it may provide improved clinical and biomechanical joint function compared to a commonly used stock device, and reduce risk of intra-operative nerve damage

    To examine the occurrence of intermittent lock, we investigated the correlation between the frequency of intermittent lock of the temporomandibular joint and magnetic resonance imaging (MRI) findings. The subjects consisted of 25 patients (25 joints) with unilateral intermittent lock who were treated from April 1994 through March 2000 at our department. MRI examination of the joint was performed on the affected side. We divided the patients into two groups: a high-frequency group consisting of 15 patients who had symptoms of intermittent lock every day and a low-frequency group consisting of 10 patients who did not have symptoms every day. The results showed no statistical difference between the two groups in clinical findings such as age, sex, clicking side of the joint, duration of intermittent lock, method of unlocking, muscle pain on palpation, degree of maximal mouth opening, distance between the maxillary and mandibular tooth midline, or the degree of overbite and overjet. However, the two groups differed significantly in the degree of anterior disc displacement as assessed by MRI. (author)

  12. RADIOGRAPHIC EXAMINATION OF TEMPOROMANDIBULAR DISORDERS IN CHILDREN

    Full Text Available The temporomandibular joint has a very important role in the stomatognathic system. Its main function is for the opening and closing movement, mastication, and speech. It is located anterior to the ear. The temporomandibular joint connects maxilla and mandible through the articular fossa, hence the slightest change that happens would cause serious matters such as pain, exiting, speech disorder, difficulty in opening and closing movement, headache, and even trismus. In a child or an adolescent, the symptoms are often vague; everything is interpreted as “pain”. This is probably why temporomandibular disorder are often undetected by dentists. Therefore, patience and accuracy is needed to determine the actual disorder through means of clinical and radiographic examination. The radiographic examination suitable for child is the transcranial projection. This projection is believed to be more accurate amongst other projection for child patients.

    A descriptive, comparative and prospective study of 132 patients with disorders of the temporomandibular joint, classified according to the degree of severity, who attended the specialized department of the Provincial Teaching Dental Clinic from Santiago de Cuba was carried out from March, 2009 to September, 2010, in order to determine the benefits obtained with the ultrasonic therapy in the sick persons. In the series, the most affected were: the female sex, the age group 40-49, and the severe cases were few in number, while the mild and moderate disorders had similar proportions. When applying the ultrasonic and conventional therapies, the group that received treatment with the first one was that with a satisfactory clinical course.

    A penetrating injury by a foreign body is comparatively common in the oral and maxillofacial region. On the other hand, injury to the temporomandibular joint (TMJ) by a foreign object is very rare. The TMJ is an anatomically narrow space surrounded by hard bony processes. An unusual case of trauma with severe trismus caused by a foreign body that impaled the TMJ is reported. A 55-year-old man presented with a 5 × 1-cm laceration to the right cheek caused by a flying object propelled during the use of a lawn mower. The edge of the foreign body had a metallic wire, which became imbedded in the wound. His jaw opening was severely limited. Computed tomography revealed that the foreign body was 3 mm in diameter and was impaled on the articular capsule. The object was successfully removed, and the wound and interior of the TMJ were irrigated. Rehabilitation of mouth opening was started on postoperative day 3. On day 9, mouth opening had improved to 35 mm, and he was discharged. After 1 year, mouth opening was 45 mm with no sign of any TMJ disorders. © 2016 John Wiley & Sons A/S.

    Full Text Available Eminectomy which is one of the popular and most effective treatments for habitual temporomandibular joint luxation was first described by Myrhaug in 1951. There are few reports which described eminectomy being performed under local anesthesia and conscious sedation. We present a case series of habitual luxation of the TMJ treated by eminectomy performed under local anesthesia and conscious sedation and general anesthesia. Five patients were examined and found to have recurrent luxation of the TMJ. The age of patients ranged from 18 to 93 years. Bilateral eminectomy of the TMJ was performed for two patients, and unilateral eminectomy was
