Purpose : Authors attempted to evaluate the effect on explanation of pathogenesis and stress management as the initial care of temporomandibular disorders. Materials and methods : The materials were 634 patients with temporomandibular disorder, who had been referred to our Department of Dentistry, Wonju Christian Hospital during recent 5 years. We examined about clinical aspects of temporomandibular disorders, such as, major signs of temporomandibular joint disorder, life environment and habits, radiological findings of temporomandibular joint and electromyography of masseter muscle. The patients were treated by explanation of TMJ pathogenesis and stress management. After that, the patient were evaluated about the effect in third week. Results : The result was more favorable (96.5% success rate) without intolerable signs of temporomandibular joint disorder. Conclusion : The explanation of TMJ pathogenesis and stress management were thought as the very effective care in management of patients with temporomandibular disorder.
Temporomandibular disorders(TMD) have been defined as a collective term embracing a number of clinical problems that involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. James Costen has mentioned about the relationship between TMD and posterior bite collapse, there have been many controversies about the etiology and comorbidities of TMD. The purpose of this study was to investigate the relationship between TMD and hearing acuity in 158 volunteers with or without TMD symptoms. The subjects were examined clinically about TMJ sound, missing teeth, tinnitus, TMJ pain and masticatory muscle pain and the hearing acuity were measured by Audiometer(ITO AE-1000, Japan). The result of this study indicated that there was no significant differences between TMD symptoms and hearing acuity relatively.

This study was designed to evaluate the diagnostic effect of the simulatneous multifilm individualized lateral tomography in the diagnosis of the temporomandibular disorders. The subjects consisted of 29 patients with symptoms of the temporomandibular disorders. The panoramic view, oblique lateral transcranial radiograph (OLTC) (Hirozontal angulation 0°, Vertical angulation 29°), submentovertex view, and simultaneous multifilm individualized lateral tomographs (SMFI) in centric occlusion (2.5㎜ thickness difference, 5 layers) were taken for the patients. This study compared the findings from each radiographs in the determining of mandibular condylar position with dual linear measurement of the subjective closest posterior and subjective closest anterior interarticular space and in the determining of bony changes on the studied 30 temporomandibular joints (TMJ) with symptoms of the temporomandibular disorders. The results were as follows: 1. The distribution of condylar position of OLTC and 5 layers of SMFI depended on the radiographs (p<0.05). The condylar position and the distribution of condylar position of OLTC were more similar to lateral sections of the SMFI than mesial sections, and in the distribution of the condylar position of SMFI, the more lateral sections of SMFI, the more concentric 2. positions. There were 10 cases in which all layers showed the same condylar position as that of OLTC. There were 3 cases in which no layers showed the same condylar position as that of OLTC. 3. In the SMFI of 30 Temporomandibular joints studied, there is 13 cases in which all five layers represented the same condylar position in the same TMJ and 11 cases in which 4 layers represented the same condylar position in the same TMJ and 6 cases in which 3 layers represented the same condylar position in the same TMJ. So at least 3 layers of SMFI represented same condylar position in the same TMJ. 4. The bony changes were not detected in conventional radiographs on the temporomandibular joint and the bony changes were not detected in simultaneous multifilm individualized lateral tomographs. The bony changes were detected in conventional radiographs on the temporomandibular joint and the bony changes were detected in simultaneous multifilm individualized lateral tomographs. SMFI provided a meams for a three dimensional visualization of the shape, the position and the extent of bony changes of TMJ.

Purpose: This study aimed to investigate the characteristics of the symptoms of temporomandibular disorders (TMD) in Korean children and adolescents using representative samples and questionnaires. Methods: A survey involving the interview of 10-, 12-, and 15-year-old children and adolescents regarding the symptoms of TMD was conducted as a part of the 2010 National Oral Health Surveys. The study population included 18,112 subjects (male, 9,734; female, 8,378). The interview involved three questions related to the symptoms of TMD. The prevalence of symptoms of TMD, correlation of the symptoms with sex and age, and the difference in the number of symptoms according to sex and age were analyzed. Results: Among the symptoms of TMD in children and adolescents, the prevalence of temporomandibular joint (TMJ) sounds during mouth opening was 13.0%, while those of TMJ pain and limitation were 3.1% and 4.3%, respectively. While the prevalence of TMJ sounds during mouth opening did not show any statistically significant difference between the sexes, the rates of prevalence of TMJ pain and limitation of mouth opening in were higher in the female subjects than the male (p<0.05). It was also observed that the older the subjects, the higher the prevalence of TMJ sounds, TMJ pain, and limitation of mouth opening (p<0.05). The number of symptoms of TMD was found to be increased among female subjects as well as the older ones (p<0.05). Conclusions: There are variations in the prevalence of symptoms of TMD among Korean children and adolescents according to sex and age, which is consistent with the results of previous studies. It is necessary to conduct a national cohort study to evaluate the risk factors for TMD in children and adolescents.
Purpose: Temporomandibular disorder (TMD) is one of the most common diseases causing chronic orofacial pain. Prolotherapy is called 'regenerative injection therapy' or 'growth factor stimulation injection', and it induces the functional reactivation of tissues such as ligaments and tendons. The aim of this study is to evaluate the efficacy of ultrasound-guided prolotherapy with platelet-rich plasma (PRP) for the patients who had the TMD symptoms, especially in temporomandibular joint (TMJ) pain, restricted mouth opening, and TMJ sound. Methods: Twenty-seven patients visited Chosun University Dental Hospital with the symptoms of pain, restricted mouth opening, and TMJ sound were included in this study. When the patients visited the hospital, we measured; the degree of pain, range of mouth opening (ROM), and TMJ sound, and grouped them according to their chief complaints. TMJ pain and ROM were measured both at the first visit and the fourth week after the PRP injection, and also evaluated the impact of the treatment on their daily activities. Results: After the treatment, the patients in the TMJ pain group showed some improvement (visual analogue scale [VAS] 5.6 to 3.6), and the patients in the restricted mouth opening group exhibited increased ROM (26 mm to 32 mm; p<0.05). On the other hand, the patients in the TMJ sound group had no improvement. Conclusions: PRP prolotherapy could be effective for the treatment of TMJ pain and restricted mouth opening. However, further studies are still necessary in terms of TMJ sound and longterm effect of PRP prolotherapy.

The purpose of this study is that evaluate the distribution and biological roles of TNF-a, interleukin-1${\beta}$(IL-1${\beta}$), interleukin-6(IL-6) and tissue inhibitors of metalloproteinase-1(TIMP-1) in the synovial fliud of patients with non-inflammatory chronic temporomandibular joint(TMJ) disorders in relation to pain during joint movements and magnetic resonance imaging(MRI) findings. TMJ synovial fluids aspirates were obtained from 36 patients (36 joints) with chronic TMJ disorders and from 8 controls(8 joints). Patients were divided to four groups. The control group was from healthy volunteers(8 joints), group I(18 joints) was patients with anterior disc displacement with reduction, group II(5 joints) was patients with disc displacement without reduction and group III (5 joints) was osteoarthritis. The TNF-${\alpha}$, IL-1${\beta}$ and IL-6 levels in the aspirates were determined by using an enzyme-linked immunosorbent assay and the TIMP-1 level was measured by an enzyme immunoassay. Following examinations for pain during joint movements and MRI observations, these cytokines' level and frequencies of detection were compared. The level of IL-1${\beta}$was not significant different in all groups. but the level of TNF-${\alpha}$, IL-6 and TIMP-1 were significant different among groups. The level of IL-6 and TIMP-1 were correlated to pain during movement(p<0.01) and the level of TNF-a(p<0.05). Also, the level of IL-6 was correlated to the level of TIMP-1(p<0.01). Especially, The level of the TIMP-1 level was significantly correlated to the pain during movement and showed very high levle of Pearson's correlation coefficient (r=0.833)(p<0.001). The results indicated that the TNF-${\alpha}$, IL-6 and TIMP-1 levels in the TMJ aspirates of patients with chronic TMJ disorders have been raised. Especially, IL-6 and TIMP-1 were very high levels in the patients who were degraded in the TMJ. Also, TNF-${\alpha}$, IL-6 and TIMP-1 showed the significant correlation in the chronic temporomandibular joint disorders. Therefore I suggest that these cytokines were also correlated to the pain during movement in the chronic temporomandibular joint disorders.
Temporomandibular joint(TMJ) disorders have characteristic clinical findings such as pain, joint sound, and abnormal jaw function. With the rapid progress in TMJ imaging techniques, magnetic resonance imaging(MRI) especially provides the clinician and researcher with the ability to evaluate TMJ disorders(effusion, anterior disk displacement) and the hard and soft tissue of the TMJ. In order to manage the internal derangement of TMJ such as anterior disk displacement, the so-called appliance therapy is commonly used. This technique became the treatment of choice before surgical intervention by many practitioners. The purpose of the present study was to evaluate and determine the efficacy of anterior repositioning splint by means of the change of the position of the disk through pre- and post-treatment MRI. MRI and clinical symptom were carefully recorded in TMJ disorder patients. The relationship between TMJ symptoms such as pain, clicking sound, and disk displacement and effusion in MRI were analyzed. Then, splint therapy was applied for 3 months according to our protocol; at day 1, patients should wear 24 hours, in order to accomodate the splint and then, wearing time is reduced to 12 hours per day for one month. During next 2 months, it is tapered to 8 hours per day according to the evaluation of the clinical symptoms. Post-treatment MRI was obtained after 3 month protocol. This treatment strategy improved the clinical symptoms of TMJ disorder, and effusion and articular disk position showed a significant change. In conclusion, a treatment modality using an anterior repositioning splint therapy is an appropriate method for temporomandibular disorder patients.
Introduction : Patients with temporomandibular disorder may have various ear-related symptoms. If an excessive load is applied to the ear area due to the skeletal shape of the mandibular condyle or malposition of the disc, an auditory problems may occur. Case report : The patient was referred to our clinic due to the suspicion of temporomandibular disorder from the local otorhinolaryngology clinic. A few days ago, his right ear could not be heard. MRI showed that the left TMJ disc was anterior displacement with reduction, the right TMJ disc was anteromedial displacement without reduction. Also Right mandibular condyle showed sclerotic bone change, subchondral cyst and was compressing the frontal wall of the ear on MRI view. Right TMJ arthroplasty was done under the diagnosis of right TMJ osteoarthritis and osteochondroma. Postoperative intermaxillary fixation was done with SAS screw and elastics for 2 weeks. One month after the operation, hearing and TMJ discomfort were recovered without any complications. Conclusions As seen in this case, hearing loss due to benign tumor-like lesions of the temporomandibular joint should be treated surgically to restore the TMJ function and hearing.

Purpose: This study investigated the prevalence of temporomandibular joint osteoarthritis (TMJ-OA) using the Research Diagnostic Criteria for Temporomandibular Disorders image analysis criteria, assessed the severity of incidental osteoarthritic changes affecting the TMJ, and evaluated the correlations of sex and age with the prevalence and severity of TMJ-OA. Materials and Methods: This retrospective study assessed 145 randomly selected cone-beam computed tomography scans (261 TMJs) from the authors' institutional maxillofacial radiology archive following the application of inclusion and exclusion criteria. The criteria described by Ahmad et al. were used to determine whether each TMJ was affected by OA, and the severity of the osteoarthritic changes was scored for each joint based on the method described by Alexiou et al. The chi-square, McNemar, Bhapkar chi-square, and Stuart-Maxwell chi-square tests were applied to evaluate the significance of the relationships between variables(age and sex). Results: Sixteen TMJs (6.1%) had no OA, 74 (28.6%) were indeterminate for OA, and 171 (65.5%) had OA. Flattening and sclerosis were observed in 86.6% and 12.3% of cases, respectively, while resorption was observed in 7.3% of the joints. Only 21 (8.1%) of the examined TMJs had subchondral cysts. Erosion of the articular eminence was observed in 58 (22.1%) cases, while sclerosis and resorption were found in 68 (25.9%) and 16 (6.1%) TMJs, respectively. Conclusion: Female patients had a higher prevalence and severity of TMJ-OA than male patients. The prevalence and severity of TMJ-OA increased with age, with peaks in the fifth and seventh decades of life.
