RESUMO
BACKGROUND: Temporomandibular disorder (TMD) is a condition encompassing clinical symptoms of the temporomandibular joint, masseter muscle, and surrounding structures. Hominis placental pharmacopuncture (HPP), consisting of human placental extract, has been reported as effective for treating chronic musculoskeletal disorders, but a lack of well-designed randomised controlled trial s (RCTs) mean there is insufficient evidence to prove the efficacy of HPP. METHODS: This study is a two-arm parallel, assessor-blinded, multi-centre, randomised controlled trial. We will enrol 82 chronic TMD patients from rwo Korean Medicine hospitals in Axis 1, Group I according to RDC/TMD diagnostic criteria, and randomly allocate 41 patients each to an HPP group and a physical therapy (PT) group. Treatment will be administered in 10 rounds, after which there will be four follow-up visits 6, 9, 13, and 25 weeks from baseline. The primary end point is 6 weeks after baseline, and the primary outcome is the difference in Visual Analogue Scale (VAS) score for temporomandibular pain between baseline and week 6. Secondary outcomes will be Numeric Rating Scale (NRS) scores for temporomandibular pain and discomfort, temporomandibular joint range of motion, the Korean version of Beck's Depression Index-II (K-BDI-II), Jaw Functional Limitation Scale (JFLS), Patient Global Impression of Change (PGIC) scores, and quality of life. Using data on adverse events and cost-effectiveness in the two groups, we will perform a safety assessment and a cost-effectiveness analysis (economic assessment). DISCUSSION: This study will assess the efficacy and safety of HPP for chronic TMD compared with PT. This RCT will provide evidence for the efficacy, safety, and economics of HPP. TRIAL REGISTRATION: clinicaTrials.gov (NCT04087005) / Clinical Research Information Service (CRIS) (KCT0004437) / IRB (JASENG 2017-09-002-002, KHNMCOH 2019-08-002) / Ministry of Food and Drug Safety (No. 31886).

PURPOSE: Dynamic stability of the temporomandibular joint (TMJ) is the characteristic of the joint to achieve normal function by harmonious, balanced, synchronized interactions of the various functional subunits of the stomatognathic system. The aim of this study was to evaluate changes in the mechanics and dynamics of the TMJ during recovery from surgical treatment of an isolated condylar fracture. PATIENTS AND METHODS: This is a prospective cohort study involving 30 patients who underwent open reduction and internal fixation for an isolated unilateral condylar fracture and were clinically asymptomatic at 6 months after surgery. The dynamics of the TMJ were assessed by bite-force analysis, both static and dynamic, to assess masticatory efficiency. Surface electromyography was recorded to assess changes in muscle dynamics. Joint vibration analysis was performed to evaluate the internal functioning of the TMJ. All the assessments were carried out bilaterally to allow comparison of the injured and uninjured joints, and the data were analyzed with the paired t test and independent-samples t test. Statistical significance was considered at P < .05. RESULTS: The study included 18 male and 12 female patients aged between 20 and 40 years. Bite-force analyses showed significantly higher bite forces on the uninjured side at 6 months after surgery. Similarly, surface electromyography analysis showed increased muscle activity on the affected side pointing toward some compensatory hyperactivity in the masticatory muscles. Joint vibration analysis showed that there was increased friction during function in both the injured and uninjured joints. CONCLUSIONS: The observations in this study suggest that residual imbalances are present in the TMJ at 6 months after open reduction and internal fixation of condylar fractures. Therefore, long-term studies are required to establish a complete timeline of adaptive changes occurring in the TMJ after condylar fractures, especially in comparison with other treatment modalities.

AIMS: To investigate the test-retest reliability of mechanical sensitivity mapping in the masseter and temporomandibular joint (TMJ) regions between sessions, days, and examiners with a fixed and standardized pressure stimulus, as well as to compare mechanical sensitivity between sides and sites. METHODS: A total of 20 healthy young volunteers participated. Pressure stimulation was applied to 15 sites in the masseter region with a Palpeter device of 1.0-kg force and to 9 sites in the TMJ region with a Palpeter of 0.5-kg force. All participants were tested twice in two separate sessions on the same day by Examiner 1 with an interval of 3 hours between tests. After 1 week, the protocol was repeated in the same manner in two separate sessions by Examiner 1 and Examiner 2 (one session each). RESULTS: Analysis of variance (ANOVA) of numeric rating scale (NRS) scores and center of gravity (COG) values in both regions showed no significant main effects of examiner, day, or session (P ≥ .167). The test-retest reliability of data implied excellent agreement (intra-class correlation coefficients all > 0.75) between different examiners, days, and sessions. In addition, the ANOVA of the mean NRS scores in both regions showed significant main effects of site (P = .001). CONCLUSION: This feasible and reliable technique may provide a new tool for comprehensive evaluation of mechanical allodynia and hyperalgesia in the orofacial region, which are common features related to temporomandibular disorders and other chronic craniofacial pain conditions.

OBJECTIVES: The aim of this study was to investigate whether the presence of a natural mediotrusive contact influences electromyographic (EMG) pattern activity in patients with temporomandibular disorders (TMDs). METHOD: Bilateral surface EMG activity of the anterior temporalis (AT), masseter (MM), and sternocleidomastoid (SCM) muscles was recorded in 43 subjects during unilateral chewing and tooth grinding. Thirteen patients had TMD and a natural mediotrusive contact (Group 1), 15 had TMD without a natural mediotrusive contact (Group 2), and 15 were healthy subjects without mediotrusive contacts (Group 3). All subjects were examined according to the Research Diagnostic Criteria for TMD (RDC/TMD). All EMG values were standardized as the percentage of EMG activity recorded during maximum isometric contraction on cotton rolls. RESULTS: EMG activity from all muscles measured showed no significant differences between groups during chewing and grinding. Overall, in all groups, the EMG activity during chewing was higher in the working side than the non-working side in AT and MM muscles. During grinding, these differences were only found in masseter muscles (mainly in eccentric grinding). SCM EMG activity did not show significant differences during chewing and grinding tasks. Symmetry, muscular balance, and absence of lateral jaw displacement were common findings in all groups. DISCUSSION: EMG results suggest that the contribution of a natural mediotrusive occlusal contact to EMG patterns in TMD patients is minor. Therefore, the elimination of this occlusal feature for therapeutic purposes could be not indicated.

Assessing the reliability of medical measurements is a crucial step towards the elaboration of an applicable clinical instrument. There are few studies that evaluate the reliability of somatosensory assessment and pain modulation of masticatory structures. This study estimated the test-retest reliability, that is over time, of the mechanical somatosensory assessment of anterior temporalis, masseter and temporomandibular joint (TMJ) and the conditioned pain modulation (CPM) using the anterior temporalis as the test site. Twenty healthy women were evaluated in two sessions (1 week apart) by the same examiner. Mechanical detection threshold (MDT), mechanical pain threshold (MPT), wind-up ratio (WUR) and pressure pain threshold (PPT) were assessed on the skin overlying the anterior temporalis, masseter and TMJ of the dominant side. CPM was tested by comparing PPT before and during the hand immersion in a hot water bath. anova and intra-class correlation coefficients (ICCs) were applied to the data (α = 5%). The overall ICCs showed acceptable values for the test-retest reliability of mechanical somatosensory assessment of masticatory structures. The ICC values of 75% of all quantitative sensory measurements were considered fair to excellent (fair = 8·4%, good = 33·3% and excellent = 33·3%). However, the CPM paradigm presented poor reliability (ICC = 0·25). The mechanical somatosensory assessment of the masticatory structures, but not the proposed CPM protocol, can be considered sufficiently reliable over time to evaluate the trigeminal sensory function.

Temporomandibular joint disorders (TMJDs) are a complex group of disorders that comprise dysfunctions of the temporomandibular joint (TMJ). In this study, we analyzed the objective and subjective findings of the TMJD patients by using Helkimo anamnesis (Ai) and clinical dysfunction (Di) indices, and tried to document a relation between these findings and magnetic resonance imaging (MRI) results.Ninety-eight patients who were admitted to our clinic were included in the study. The clinical evaluation was performed by using Ai, an 8-question-survey based on the objective symptoms of patients; Di, concluded as the score of 5 objective measurements of physical examination. The morphology of the TMJ was evaluated by MRI, and the findings were analyzed and statistically compared with respect to the Di.The most commonly seen symptoms were noise during mandibular movement (58%), pain around the joint (42.5%), and pain with mandibular movements (40%). Seventeen patients (17.3%) were Di0, 47 (48%) were DiI, 24 (24.5%) were DiII, and 10 (10.2%) were DiIII. Thirty-seven patients (37.8%) had abnormal MRI findings, whereas 61 patients (62.2%) had normal MRI. The most commonly encountered pathology was anterior disc displacement with reduction, which was reported in 15 patients. Increased TMJ Di, which points a more progressed TMJD, was found to be significantly related with the pathological MRI findings (Pâ<â0.05).MRI is especially effective in particularly those with high Di; therefore, the results of the study may give a prospect in which types of patients does MRI give a valuable data toward diagnosis, in which stages of the TMJD should we expect pathological findings, and thereby preventing unnecessary use of MRI in patients with symptoms of TMJD.

This retrospective clinical study was performed to evaluate whether a visual or quantitative method is more valuable for assessing painful temporomandibular disorder (TMD) using bone scintigraphy results.In total, 230 patients (172 women and 58 men) with TMD were enrolled. All patients were questioned about their temporomandibular joint (TMJ) pain. Bone scintigraphic data were acquired in all patients, and images were analyzed by visual and quantitative methods using the TMJ-to-skull uptake ratio. The diagnostic performances of both bone scintigraphic assessment methods for painful TMD were compared.In total, 241 of 460 TMJs (52.4%) were finally diagnosed with painful TMD. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the visual analysis for diagnosing painful TMD were 62.8%, 59.6%, 58.6%, 63.8%, and 61.1%, respectively. The quantitative assessment showed the ability to diagnose painful TMD with a sensitivity of 58.8% and specificity of 69.3%. The diagnostic ability of the visual analysis for diagnosing painful TMD was not significantly different from that of the quantitative analysis.Visual bone scintigraphic analysis showed a diagnostic utility similar to that of quantitative assessment for the diagnosis of painful TMD.

The pathophysiology and underlying pain mechanisms of temporomandibular disorders (TMD) are poorly understood. The aims were to assess somatosensory function at the temporomandibular joints (TMJs) and to examine whether conditioned pain modulation (CPM) differs between TMD pain patients (n = 34) and healthy controls (n = 34). Quantitative sensory testing was used to assess the somatosensory function. Z-scores were calculated for patients based on reference data. Conditioned pain modulation was tested by comparing pressure pain thresholds (PPTs) before, during, and after the application of painful and nonpainful cold stimuli. Pressure pain thresholds were measured at the most painful TMJ and thenar muscle (control). Data were analyzed with analyses of variance. Most (85.3%) of the patients exhibited at least 1 or more somatosensory abnormalities at the most painful TMJ with somatosensory gain with regard to PPT and punctate mechanical pain stimuli, and somatosensory loss with regard to mechanical detection and vibration detection stimuli as the most frequent abnormalities. There was a significant CPM effect (increased PPT) at both test sites during painful cold application in healthy controls and patients (P < 0.001). There was no significant difference in the relative CPM effect during painful cold application between groups (P = 0.227). In conclusion, somatosensory abnormalities were commonly detected in TMD pain patients and CPM effects were similar in TMD pain patients and healthy controls.

Altogether 4606 volunteers (2923 vomen, 1683 men) participated in the representative national epidemiological study to screen the alterations of temporomandibular joint (TMJ). The characteristic clinical signs and subjective complaints according to TMJ were evaluated by medical history taking and physical examination. Regarding the orthodontic anomalies, the vertical abnormalities (deep bite and open bite) were specifically noted. Clinical signs showing functional problems of TMJ were found in 45.19% of the screened population, mainly in the group of 35-44 year olds. The frequency of clicking and crepitation of TMJ was significantly higher in women compared to men (p < 0.05). The highest rate of clinical signs of TMJ disorders was found in the South-Transdanubian region, the lowest rate in the Middle-Transdanubian region, between these regions it was a significant difference regarding the frequency of deviation/deflexion (p < 0.05). Of the vertical abnormalities, deep bite occured most frequently in the 35-44 ys old age group. The prevalence of deep bite was higher among males than females in the whole screened population, but the difference was not statistically significant. Significant relationship was detected between deep bite and TMJ pain, deep bite and noises in the joint in the majority of the population. The most frequent anomaly in the South-Transdanubian region was deep bite, while the open bite occured most frequently in south middle part of Hungary. Conclusion: the Hungarian population needs well organized specific programs to improve the oral health including TMJ and orthodontic aspects.

THE PURPOSE OF THE PAPER: Qualitative and quantitative analysis of selected parameters of mandible movements, electronically registered in patients with temporomandibular joint dysfunction and healthy ones. MATERIAL: Function test of the mandible movements was conducted in 175 patients. Gender distribution was 143 women and 32 men, aged 9 to 84. METHODS: The studied population, after accurate clinical examination, was divided into age groups with the range of five years. All the patients had Zebris JMA computerized facebow examination done, according to the generally accepted principles and procedures. RESULTS: Mean values of mouth opening calculated to 45.6 mm in healthy group and 37.6 mm in TMJ dysfunction group. Mean length of condylar path amounted to 39 ± 7% of the maximum value of mouth opening in the group of healthy people, 44 ± 11% in the case of muscle-based disorders, and 35 ± 11% with joint-based. The mean value of the condylar path inclination oscillated in the range of 25° to 45°. CONCLUSIONS: The ratio of length of the condylar path to the size of mouth opening may be a significant value characterising the type and degree of intensification of the TMJ dysfunctions.

The aim of this study was to axiographically analyse the mobility of the condyles of the temporomandibular joints in patients with partial edentulism in lateral sections and try to specify whether the partial edentulism has an impact on the severity of temporomandibular disorders. 60 subjects with partial edentulism (different range groups) and 20 subjects in the control group (full dental arches) were examined. Every patient underwent a thorough clinical examination, including axiography conducted by means of Cadiax Compact II® system. The results show some correlation between the advancement of temporomandibular joint disorder, the range of partial edentulism and the abrasion of the residual teeth. In the study, a significant intensification of dysfunction symptoms and restricted condylar path was observed in patients with the largest partial edentulism and significant level of tooth wear of the residual teeth. A significantly higher percentage of asymptomatic subjects or those with minor dysfunction was also found among the patients with lowest-range partial edentulism in lateral sections.

The diagnosis of temporomandibular joint (TMJ) disorders consists of clinical (Reaserch Diagnostic Criteria for Temporomandibular Disorders, RDC/TMD) and additional (computer tomography, CT or magnetic resonance imaging, and MRI) examinations. Due to the growing knowledge of pathologic changes within the TMJ, the researches become more aware of the difficulty in detection the early symptoms of disorders using conventional examination. Therefore, it is now expected that the collected samples of synovial fluid, serum, or urine samples could enable easier identification of inflammatory process course, and degenerative cartilage changes state.

Mandibular fractures are among the most common trauma injuries of the craniomaxillofacial region. This study evaluated the late results of mandibles fractures treated with arch bar. Forty-nine patients were examined clinically and by questionnaires for late results of arch bar treatment. Demographic data (age, sex, etc), trigeminal nerve sensation (Weber test), temporomandibular joint evaluation, masticatory muscle function, and occlusion were recorded. The data were analyzed by χ test using Sigma Stat 2.0 software. Fifty-one percent of the patients with angular fractures complained of sensory disturbances. Condylar and angular fractures demonstrated higher levels of pain. According to Pearson χ test, a statistically significant relation between angular fracture and tenderness of the internal pterygoid muscles (P = 0.047), angular fracture and cross-bite (P = 0.021), parasymphysial fracture and pain upon wind blowing (P = 0.026), and body fracture and mastication discomfort (P = 0.038) was found. In closed reduction therapy, fracture location of the mandible seems to be more likely correlated in producing particular long-term complications. Regular follow-ups for functional treatments and physiotherapy of chewing muscles and temporomandibular joint, along with removal of occlusal abnormalities, should be considered following arch bar reduction of mandibular fractures.

Patients who fail to respond to routine conservative measures to treat pain, restriction, and locking in the temporomandibular joint (TMJ) may have therapeutic arthroscopy or arthrocentesis, both of which are associated with symptomatic improvement in 86% of patients. To our knowledge there are no current data on improvements in mouth opening and lateral deviations after these procedures. This prospective audit includes 244 patients treated between 2005 and 2010 from one surgeon's practice, who were followed up at least once at 6 weeks after arthroscopy or arthrocentesis. They had various conditions but all had tender joints. Measurements of interincisal opening, left and right lateral excursions, and protrusion were taken before and during operation with callipers (mm). Opening and pain scores were also recorded on 10 cm analogue scales before operation and at 6 weeks. Pain scores improved with intervention from a mean score of 37.1-16.1 (range 0-100). The improvement in mouth opening ranged from 0 to 78% (as some patients had locking or pain with normal opening before operation), and 86% had improved enough to be discharged at 6 weeks. Temporary forehead weakness in two patients resolved within the timescale of the study. The study shows improvements in mouth opening, and confirms that pain scores can be improved after arthroscopy or arthrocentesis when conservative approaches have failed. In the hands of a skilled practitioner, arthroscopy can be a useful diagnostic and therapeutic adjunct, which can be used repeatedly with low morbidity.

The research analyzes diagnostic TMJ's disease's identification work of stomalogists owned to different types of day care properties (municipal, departmental, private). This research based on examination of primary medical records of 1906 patients aged 61 to 89 years, including 2978 prescribing lists made by stomatologists - orthopedists to dental outpatient's card. This research shows that in case of outpatient conditions in the primary examination of patients of elderly and senile age stomatologists pay attention to joint pathology in the presence of acute patients' complaints, caused by TMJ's displacement, arthritis, painful TMJ's dysfunction or pronounced sound phenomena of TMJ. Stomatologists examine TMJ's pathology more particularly. The TMJ's pathology complicates the tooth replacement made to patients contrary to absence of indications of disease presence in primary medical records. The prepared conclusion and recommendations allow improving the outpatient diagnosis of TMJ's pathology.

OBJECTIVE: The aim of the present study was to evaluate the symptoms of temporomandibular dysfunction (TMD) in patients with obstructive sleep apnea treated with long-term use of an oral appliance (OA) using a questionnaire based on the Helkimo Anamnestic Dysfunction Index. A further aim of the study was to evaluate the presence of daytime sleepiness using the Epworth Sleep Scale (ESS) and otologic symptoms. MATERIALS AND METHODS: Polysomnograms of 34 patients were performed at baseline and after 6 months of OA use. As follow-up, the patients were contacted by telephone interview to answer the same questionnaires after 36.0 +/- 17.0 months. RESULTS AND DISCUSSION: The intensity of TMD symptoms decreased significantly throughout treatment (p < 0.01). ESS values improved from 12.2 +/- 5.0 to 6.9 +/- 2.6 (p < or = 0.05). Tinnitus was present in nine patients at baseline and decreased in intensity in seven patients by the final assessment while remaining at the same level in two patients. CONCLUSIONS: We conclude that long-term usage of an OA does not cause impairment to the temporomandibular joint. The Helkimo and otologic indexes are simple and useful in long-term patient follow-up. There was a long-term improvement in the ESS values over the years analyzed. A follow-up program could increase compliance by motivating patients to use the device regularly.

PURPOSE: This observational study was done to identify the signs and symptoms of temporomandibular joint (TMJ) involvement in patients with rheumatoid arthritis (RA) and to assess the association between these and quantitative measurements for the evaluation of rheumatologic disease. PATIENTS AND METHODS: The sample comprised 61 patients suffering from RA whose signs and symptoms of TMJ were recorded by means of a questionnaire (scale of limited mandibular function) and clinical measurements (pain during jaw movement, limitation of maximal mouth opening, joint sounds, tenderness on TMJ palpation, tenderness on masticatory muscle palpation). These findings were correlated with the quantitative measurements for evaluating RA: duration of the disease, positivity for rheumatoid factor, Health Assessment Questionnaire (HAQ) score, number of edematous and painful joints, and overall assessment of functional status. RESULTS: In terms of overall figures, 70.5% of the patients presented with at least 1 sign or symptom, 49.2% had at least 1 symptom, and 54.1% had at least 1 sign. The variable pain on movement was associated with the number of painful joints and the overall assessment findings (P < .05). Sound on movement was positively associated with the number of edematous joints (P = .0291). The scale of limited mandibular function was statistically significantly correlated with 4 quantitative measurements (P = .0283 to .0448). The variable pain on palpation of the masticatory muscles was associated with the number of painful joints (P = .0023). Pain on palpation of the TMJ was statistically significantly associated with the HAQ score (P = .0344) and with the number of painful joints (P = .0006). CONCLUSION: A significant percentage of the patients with RA have signs and symptoms of TMJ involvement, and the scale of limited mandibular function proved to be an important measurement tool.

PURPOSE: This study compared the functional kinematic outcome of the temporomandibular joint (TMJ) in patients with end-stage TMJ osteoarthritis before and after TMJ hemijoint replacement surgery. MATERIALS AND METHODS: Fourteen patients (15 joints), with a mean age of 46.1 years, undergoing metal fossa eminence hemijoint replacement surgery, participated in this study. Each patient's jaw motion was recorded using an electromagnetic tracking device and patient-specific computed tomography images. A visual analog scale patient response questionnaire was used before and after the operation to assess the subjective outcome of the surgery. RESULTS: The mean linear distance (LD) traveled by the incisors increased significantly due to the surgical intervention, from 30.4 +/- 6.9 mm preoperatively to 35.5 +/- 5.3 mm postoperatively (P = .02). The LD of the operated condyle decreased from 14.1 +/- 5.7 mm to 11.4 +/- 6.2 mm, but this was not significant. The mean LD for the unoperated condyle remained similar (preoperative, 13.2 +/- 5.9 mm; postoperative, 13.3 +/- 6.5 mm). The total mandibular rotation increased significantly, from 19.3 +/- 4.9 degrees preoperatively to 24.8 +/- 3.9 postoperatively (P < .01). CONCLUSIONS: Kinematic data support the functional efficiency of hemijoint replacement surgery, with benefits of increased maximal mouth opening, preservation of operated and unoperated condyle translation motion, and increased mandibular rotation.

PURPOSE: The purpose of this study was to evaluate the differences in the recovery of maximum mandibular opening (MMO), and the relationship between MMO and the maxillomandibular fixation (MMF) period after sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy (IVRO), with and without Le Fort I osteotomy. PATIENTS AND METHODS: Sixty-eight patients with diagnosed mandibular prognathism with or without asymmetry were divided into 4 groups (SSRO, IVRO, SSRO with Le Fort I osteotomy, and IVRO with Le Fort I osteotomy). MMO and the MMF period were measured preoperatively and at 1, 3, 6, 12, and 18 months after surgery. The differences among surgical procedures and the relationship between MMO and the MMF period were examined statistically. RESULTS: In relation to time-dependent changes in MMO, there were no significant differences among the groups. There were significant positive correlations between MMO and the MMF period from 1 month to 6 months after surgery. However, there were no significant correlations at 12 and 18 months after surgery. CONCLUSION: This study suggests that there were no significant differences between single-jaw surgery and double-jaw surgery in terms of postoperative time-dependent changes in the recovery of MMO. However, the MMF period was associated with the recovery of MMO.
