Results : Assessment was made by self assessment of subjective symptoms and clinical observacon. The patient reported over-90% remission and returned to ordinary daily life after 20months of therapy, which effect was reported to maintain for 9 months. Conclusions : An impressive effect was observed and further clinical and biological research on FCST is expected.
The causes of tongue pain and discomfort include systemic disease, malnutrition, mental illness, fungal infection, and neuropathy. Three postmenopausal women reported burning sensations and stiffness of the tongue for various periods, from one month to four years. There were no objective etiological factors to cause the tongue pain and discomfort. Muscular tenderness upon palpation of masticatory muscles, sternocleidomastoid, trapezius, and tongue were observed. Physical therapy approaches such as moist hot pack, ultrasound, and myomonitor were performed on three patients with tongue pain, just as for temporomandibular joint disease. Additional botulinum toxin injection therapy was applied to one patient who displayed a clenching habit. All three patients showed a marked improvement in their tongue symptoms after the muscle relaxation and botulinum toxin injection therapy.
Temporomandibular disorder(TMD) is relatively prevalent disease, and quality of life may be impaired in TMD patients. Like general population, dental hospital workers are also exposed to the risk of TMD. But, many of them tend to overlook or tolerate their symptoms for lack of time and interest. Therefore, problems may become more serious, causing interference of performing task and decrease of quality of life. The aim of this study were to obtain data for TMD prevalence in dental hospital workers and to evaluate quality of life according to TMD symptoms. Subjects were recruited from Wonkwang University Dental Hospital. After consent, subjects completed quality of life questionnaire and were evaluated for subjective and objective signs and symptoms of TMD. Subjects were classified into 4 groups : (1) normal group (2) joint disorder group, (3) local myalgia group, and (4) myofascial pain group. The result of the study indicated that TMD negatively influences the quality of life in dental hospital worker. TMD symptoms can deteriorate quality of life in dental hospital worker. Future effort to make protocol for proper management is needed.
The purpose of this study was to investigate the relationship between stress and oral symptoms, and quality of life in university students. This survey was performed on 452 university students in the Daejeon area. The research was conducted during 2 weeks in June 2016 using a self-reported questionnaire. The data were analyzed by PASW Statistics ver. 18.0. According to the findings of the study, higher levels of stress were detected in girls than in boys (p<0.05). Stress had a significant impact on the symptoms of dry mouth, bad breath, and temporomandibular pain (p<0.05). The high-stress group experienced a negative impact on oral impacts on daily performance (OIDP) scores as compared to the group with lower stress. Stress had a significantly positive correlation with dry mouth, bad breath, temporomandibular joint (TMJ). OIDP was a significant positive correlation with dry mouth, bad breath, TMJ and stress. The findings of the study showed that stress exerted a significant influence on the oral symptoms and quality of life in university student.
This study tried to find the prevalence and distribution of temporo-mandibulr disorders(TMD) for workers (employee) in Seoul area to investigate the correlation between TMD and possible etiological factors such as general muscle and joint symptoms, headache, unilateral chewing and parafunction. This study was an epidemiological investigation of answers obtained from 282 persons by questionaire from Aug. 1995 to Nov. 1995. The major findings from the questionaire were as follows. (1) 43.26% of the subjects(282 persons) has TMD. (41.88% of man and 43.26% of women) (2) The more often people have general muscle and joint symptoms and headache, the more susceptible they are to TMD. Their correlation was very significant(p<0.001). (3) The more people have bad oral habits such as bruxism, clenching and biting habit, the more likely they have TMD. The more sensitive people are to stress, the more frequently they have bad oral habits such as bruxism, clenching and biting habit. (4) Unilateral chewing has higher TMD index than bilateral chewing. There is no relationship between ache areas and TMD index.
Aimed at office workers at their height of Temporomandibular joint disorder(TMD), organized self-filling questionnaires were distributed from January 7 to 26, 2008 to 216 workers in the fields of service, office work, and production in D metropolitan city, to get a proper recognition about prevention and treatment of TMD by observing how strongly occupational stress influence on them. The findings of the study were as follows: 1. For subjective symptoms of joint noise as TMD, occasional was 45.8% and often 12.0%, while for joint dislocation often was 12.0%. 41.2% said they feel pains while chewing, while 24.1% said they occasionally feel pains while not chewing. 2.8% said they often experience mouth-opening disorder. 2. For joint noise, answers were significantly different according to their ages, while 30's are at their height (P < 0.05). For joint dislocation, the shorter they worked the more they have it, so less than a year worker was 37.9%, while less than 3 years 31.0%, and less than 5 years 20.7%. For work type, daytime workers have more dislocation, 58.6%, than shift-workers 34.5% (P < 0.05, P < 0.01). For pains while chewing, the shorter they worked, the more they experienced, which is the same as mouth-opening disorder (P < 0.01). 3. Workers with mouth-opening disorder have much stress on occupational autonomy (P < 0.05) and workers with dislocation and pains while chewing have much stress on relation trouble (P < 0.05, P < 0.01). Workers with highly occupational insecurity has much trouble on dislocation and pains while chewing, while workers with dislocation have significantly much stress on unproper compensation (P < 0.05). 4. For who have joint dislocation, they have much stress on relation-trouble, occupational disorder, and un-proper compensation (P < 0.01, P < 0.05). Workers with pains while not chewing showed significant difference about occupational insecurity and relation troubles (P < 0.05, P < 0.01). Who have mouth-opening disorder showed significant difference about occupational autonomy (P < 0.05).

The authors analyzed the morphological change of bone structure from 3,140 radiographs (1570 joints) of 785 patients with temporomandibular joint arthrosis, which were obtained by the oblique lateral transcranial projection and orthopantomographs. The interrelation of bone change and clinical symptoms, duration of the diseases were examined. Also, the bone changes of articular eminence, condyle, articular fossa were examined according to positional change of the condyle in the mouth open and close state. The results were as follows. 1. In the 785 patients with TMJ arthrosis, 782 patients (99.62%) show the positional change of the condyle. Among them 691 patients (88.03%) show the bone change. 2. In TMJ arthrosis patients with bone changes 451 patients (65.27%) showed both the condylar positional changes and bone changes bilaterally. 198 patients (28.65%) show the condylar positional changes bilaterally and bone changes unilaterally. 3.

The authors examined the condylar position and shape of condylar process from the transcranial radiographs and polytomographs of the 130 temporomandibular joints of 65 patients who complained symptoms of temporomandibular disorder and the followings were obtained; 1. The age and sex distribution of the 65 patients showed peak incidence in 2nd decade (27.7%) followed by 3rd (18.5%) and 4th decade (18.5%) and female predominance (87.7%). 2. In polytomography 64 joints (49.2%) showed consistent condylar position from lateral to medial and 39 joints (30.0%) of them showed agreement with those of transcranial radiographs. Among the 66 joints (50.8%) which showed changes in condylar position. 48 joints (36.9%) showed agreement with lateral and central tomographic and transcranial radiographic position. 41 joints (31.5%) showed disagreement in condylar position between the polytomographic and transcranial radiographic images. 3. When the condylar position was classified as anterior, central and posterior. the posterior position was the most frequent position, that is . 42.3% of the transcranial radiography and 42.3%.49.2% and 38.5% of the lateral, central and medial polytomographic radiographs. 4. In polytomography 84 joints (64.6%) showed consistent condylar shape from lateral to medial and 74 joints (56.9%) of them showed agreement with those of transcranial radiographs. Among the 46 joints (35.4%) which showed changes in condylar shape. 40 joints (30.1%) showed agreement with lateral and central tomographic and transcranial radiographic shape. 41 joints (31.5%) showed disagreement in condylar shape between the polytomographic and transcranial radiographic images.
The purpose of this study was to analyze the mandibular asymmetry of the patients with the temporomandibular dysfunction. In this study, 20 dental students aged between 22 and 27 years, Chosun University, who did not possess any restoration and symptoms like the temporomandybular joint click, pain, and opening limitation of the mandible were selected as the normal group. And 80 patients who were analyzed into the patients with the temporomadibular dysfunction(TMD) were divided into group I as the internal derangement and group II as external derangement. Both the normal group and the TMD Group were faked submento-vertex cephalogram by routine methods after that the unilateral mandibular length(L) and the amount of mandibular asymmetry and deviation were measured and analyzed. The results were as follows : 1, Unilateral mandibular length(L) of the normal group and the TMD group were $112.7{\pm}10.20mm\;and\;102.65{\pm}8.10mm$ respectively (P<0.01). 2. The amount of mandibula asymmetry of the normal group and the TMD group were $5.95{\pm}4.63mm\;and\;5.68{\pm}4.35mm$ respectively (P<0.5). 3. The amount of mandibular deviation of the normal group and the TMD group were $6.00{\pm}4.07\;and\;4.67{\pm}3.40mm$ respectively (P<0.3). 4. In the TMD group, unilateral mandibular length(L) in the affected site and the non-affected site were $102.73{\pm}8.68mm\;and\;102.53{\pm}7.68mm$ respectively (P<0.5).
The aim of this study was to investigate the relationship between velocity and factors which could affect the velocity of mandibular movement. For this study, 30 dental students without any masticatory signs and symptoms and 90 patients with temporomandibular disorders(TMD) were selected as the control group and the patients group, respectively. After determining Angle's classification and lateral guidance pattern of occlusion, clinical examination for TMD was perfomed. Velocity and distance of mandibular movements were recorded with BioEGN, reproducibility index of lateral excursions was evaluated by Pantronic(PRI) and BioEGN (BERI) activity in masticatory and cervical muscles were measured with BioEMG, and occlusal contact time and cross-arch unbalance(Total left-right statistics, TLR) on clenching were recorded with T-scan, respectively. The results of this study were as follows : 1. Velocity in the patients was faster than that in the controls in most mandibular movements, but on wide opening and closing movement, result was reverse. 2. Velocity on closing movements were faster than that on opening movements in the control group and a similar tendency was also shown in the patients group. 3. Patients with muscle disorders showed a tendency to have the highest value of velocity of all diagnostic subgroups, while patients with degenerative joint diseases showed a tendency to have the lowest value. 4. Patients with canine guidance showed a tendency to have the highest value of velocity in three subgroups by lateral guidance pattern, while patients with group function showed a tendency to have the lowest value. 5. BERI had a positive correlation with opening velocity on lateral excursion, while TLR had a negative correlation with opening velocity on swallowing. 6. EMG activity on clenching in masticatory muscles had negative correlation with opening velocity on border movements, and on swollowing, while the activity in rest correlated positively with opening velocity on border movements. 7. There were positive correlation between the velocity and the distance in long components of mandibular trajectory.
