Parkinson's disease (PD) is a chronic degenerative disorder of the central nervous system. It has no cure, but current treatments can relieve symptoms and maintain quality of life. As PD progresses, controlling its symptoms becomes difficult. Here, we present the treatment of two patients with idiopathic PD using traditional Korean medicine (TKM) and temporomandibular joint balancing therapy (TBT). We measured the progress of the two patients using the unified PD rating scale (UPDRS) and the Hoehn and Yahr (HY) scale. Combined treatment of TKM and TBT decreased the total UPDRS score from 52 to 26 after 21 days in case 1, while it decreased the total UPDRS score from 91 to 65 after 20 days in case 2. In both patients, the HY scale score was maintained at 3, and no adverse events were observed. Thus, the combined treatment of TKM and TBT can produce a treatment response in PD patients.

Disc displacement, deformation, perforation or osteoarthritis may induce the joint space narrowing. This study was designed to get the normal joint space width which could be used as a standard comparing with damaged joints. Twenty asymptomatic volunteers' MR images were evaluated and coronal images of thirty joints having normal disc position in sagittal and coronal views, were selected. The joint spaces were measured at center, medial and lateral side on the coronal views. In normal joints, the mean joint space was $3.57{\pm}0.63mm$ at center, $2.77{\pm}0.51mm$ at medial and $2.41{\pm}0.41mm$ at lateral side of mandibular condyle. The mean of joint space of male was wider than that of female at center, but not significantly different at medial and lateral side of the condyle.

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.

Arthrocentesis is a simple, less invasive, inexpensive, and highly efficient procedure for closed lock of the temporomandibular joint with regard to the lack of recurrence of symptoms during extended periods of follow-up and significiant improvement in pain and jaw function. It can be performed under local anesthesia. Arthrocentesis closed lock provide sustained normal joint function and marked pain relief. This study is the clinical outcome of arthrocentesis for closed lock of the temporomandibular joint. 160 patients(169 joints) who had experienced sudden-onset, persistent limited mouth opening were the subjects of this study. Arthrocentesis of the upper compartment of the affected TMJ was performed using normal saline. As results, at 3-60 months postarthrocentesis maximum mouth opening(MMO) had increased from mean of 27.7mm to 43.5mm, contralateral movements(CLM) from mean 5.74mm to 9.55mm, midline deviation during mouth opening from mean 3.04mm to 0.69mm. In 130 cases there was a history of joint noises, in 52 cases all noise had ceased after procedures.

A 31-year-old male with the complaint of severe limitation of mouth opening was referred to our department of Chonbuk National University Hospital. The physical status of the patient was hyposthenic. Extraoral examination showed no condylar movement of the both temporomandibular joints, no pain, no facial swelling or paresthesia. Intraoral examination showed several cervical caries on the upper anterior teeth, and gingival swelling on the whole dentition. Transcranial view showed no condylar movement, and narrowing of joint spaces. Chest P-A view showed straightening of thoracic, lumbar spine, and squaring of vertebrae of the same spines. Conventional lateral radiograph of cervical spine showed calcification of the intervertebral ligament. Computed tomograph showed extensive bone formation between temporal bone and the condylar head at both sides. Laboratory findings showed positive reaction on HLA-B27 histocompatibility antigen and increased level of IgA, IgG, ESR. Based on the clinical, radiographic, and the laboratary findings, final diagnosis was made as bony ankylosis of the both temporomandibular joints secondary to ankylosing spondylitis.

Purpose: The purpose of this study is to induce artificial arthritis on rabbit TMJ by injecting collagenase. Materials and Methods: An experimental animal model of arthritis induced by surgical method or intraarticular injection of chemical agent like LDH, papain, ketorolac. Surgical method is complex and needs a long time in inducing arthritis. Intra-articular injection of chemical agent like LDH, papain, ketorolac is simple. But chemical agent like LDH, papain, ketololac needs multiple injections to induce arthritis and mechanism inducing arthritis was known. Collagenase destroys helical domain of type II collagen in extracellular matrix produced by chondrocyte and then induces arthritis. We injected collagenase (0.5, 1.0, 2.0 mg) into the temporomandibular joint of rabbit. In the control group saline was intra-articularly injected. The condylar cartilage, disk and synovia were histologically examined at 1, 2, 4, 6 weeks after the initiation of collagenase injections. Results: Four weeks after injection of 2.0 mg collagenase, we could see histologic change like arthritis. In other groups, we couldn't see arthritis-like change. Conclusion: In our study, we produce arthritis on temporomandibular joint of rabbit by using injection of collagenase in temporomandibular joint of rabbit. And this experimental osteoarthritis is a useful animal model.

The purpose of this study is to investigate the cephalometric characteristics of the open-bite patients with DJD of TMJ. The DJD open-bite cases were compared with normal samples and Class II open-bite cases with normal TMJ respectively. Twenty three open-bite patients with bilateral DJD of TMJ($13.9\~35.3$ yens old, Group I) were selected from the Department of Orthodontics, SNUDH. Group ll consisted of thirteen Class II open-bite cases($13.2\~27.4$ years old) with no TMD signs/symtoms and good condylar shapes. Group III samples were the forty eight healthy dental students who have Class I molar relationships with no history of orthodontic treatment, good facial balance and no TMD symptoms($20.0\~26.8$ years old). First, sixty measurements in the lateral cephalometric radiographs and analysis of variance(P<0.05, Scheffe) were used to compare these three groups. The seven measurements showed significant difference(p<0.05) between Group I and Group II. After analysis of variance, six of them were used for the discriminant analysis(Wilks' stepwise analysis) and the discrminant function for Group I/Group II was obtained. The results and conclusions were as follows : In most of the measurments, Group I and Group II showed the same skeletal and dental characteristics. But seven of the sixty measurements(FH-PP angle, SNB, FH-ArGo angle, articulare angle, genial angle, upper gonial angle and Ar-Go length) were significantly different(p<0.05) between Group I and Group II. These differences may be explained by the fact that in DJD cases the mandible rotated backward due to the shortening of the ramus following the degenerative destruction of condylar head and its surrounding structures. The resulting discriminant function was : $D={-0.120X}_1+{0.066X}_2+{0.144X}_3-{0.058X}_4+2000,\;where\;X_1=ArGo\;length(mm),\;X_2=SArGo\;angle(degree),\;X_3=FH-PP\;angle(degree),\;X_4=Gonial\;angle(degree)$. Mean of the group centroids was -0.555 and percent of the 'grouped' cases correctly classified was $88.89\%$.

Purpose : Disc and condylar position were observed on MRIs of temporomandibular joint disorder patients and condylar position agreement between MRI and tranascranal radiography was evaluated. Materials and Methods MRI and transcranial radiographs of both TM joints from 67 patients with temporemandibular 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. Results. 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 (11.9%) with that of lateral, and 23 joints (17.2%) disagreed with that of MRI. Conclusion : On MRT, most oi 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.

Tempormandibular Joint pain and dysfunction is a common and important clinical problem. With the recent advances in imaging technology, radiologists have made major contribution to the understanding of TMJ disease. The MRI has several advantages over the conventional imaging methods. It is possible to obtain surprisingly precise images of internal hard and soft tissues with MRI. It is not invasive without ionizing radiation. The abnormal disk position has been thought as the cause of TMJ internal derangement. But there are few methods to relate disk position to TMJ internal derangement quantatively. The object of our study is to determine the amount of anterior displacement fo articular disk in symptomatic patients related each symptoms. Using the method of Dr. Drace, we studied the 38 joints of 22 persons with susceptable TMJ internal derangement. 1. In determining the anterior displacement of TMJ articular disk, the junction between the posterior band and bilaminar zone was useful. 2. The mean anterior displacement of disk in reduction group and without reduction group were $51.0^{\circ}C$ and $81.1^{\circ}C$ respectively. The difference was significant. 3. In the mean anterior displacement of disk, the pain without clicking group showed $84.8^{\circ}C$ and the clicking and pain group $70.8^{\circ}C$, the clicking group respectively.

The purpose of this study was to assess the pain-relieving effect of iontophoretically applied prednisolone on the patients with temporomandibular joint (TMJ) pain. 30 TMJ pain patients participated in this study. Inclusion criteria for subject selection were 1) tenderness of TMJ on palpation and 2) visual analog scales (VAS) of above 20 mm. The patients with polyarthralgia, rheumatic arthralgia, and systemic diseases were excluded for this experiment. The patients were randomly assigned to one of three groups; (1) Group 1 for administration of 2% prednisolone, (2) Group 2 for administration of 1% prednisolone, and (3) Group 3 for administration of saline. Phoresor PM600(Motion Control Utah, U.S.A) was used for administration of drugs by iontophoresis. Baseline and post-medication pain levels were recorded by VAS, pressure pain threshold (PPT), and palpation index (PI). Post-medication data were compared with baseline data for each group. The results were as follows : 1. All the groups showed significant decrease of VAS scores after treatment. 2. PPT was significantly increase only in Group 1 and 2 not in Group 3. 3. PI was significantly decreased only in Group 1 and 2 not in group 3.
