Interaction between pain and sleep has long been proved through many researches, and various studies are being conducted to identify its mechanism. However, these studies have targeted on patients with systemic disease, such as rheumatic disease and fibromyalgia. There are few researches on patients with orofacial pain including temporomandibular disorder(TMD). In this study, we studied interaction between pain aspect and sleep quality in 229 patients with TMD, who visited the TMJ and Orofacial pain clinic. Pittsburgh Sleep Quality Index(PSQI), Epworth sleepiness scale(ESS) questionnaire were surveyed and sleep-screening device was operated. PSQI showed that sleep quality in TMD patients with pain was poorer than that in TMD patients without pain. The ratio of poor sleeper was higher in TMD patients with pain. Especially, TMD patients with chronic pain showed obviously poorer sleep quality than TMD patients with acute pain. The result of ESS showed that patients with painful TMD showed more daytime sleepiness than painless TMD patients. The ratio of TMD patients with chronic pain who had daytime sleepiness was higher than TMD patients with acute pain, and the amount of daytime sleepiness was higher in the group of chronic pain. In TMD patients with chronic pain, only the poor sleeper(PSQI>5) presented mean ESS>10(diagnostic criteria of daytime sleepiness). There was no correlation between pain intensity and sleep quality or daytime sleepiness. The result of ApnealinkTM for screening of sleep related breathing disorder showed that only 1 patient presented AHI>5 among 19 participants. TMD patients with chronic pain presented poor sleep quality and excessive daytime sleepiness similar to other chronic pain patients. Evaluation of sleep state by questionnaire might be useful for diagnosis and management of TMD, because sleep disturbance decreases pain threshold and pain disturbs sleep. In addition, sleep-screening device would be useful for screening sleep related breathing disorder in dental clinic.

Poor posture of the neck and head has long been recognized as a factor contributing to the onset and perpetuation of pain in the head and neck region. This study were to evaluate the change of the neck pressure pain threshold in long term computer users. To elucidate change of the neck pressure pain threshold in long term computer users, the effect of computer using time(3, 6, 9, 12 and 15 hours) on neck pressure pain threshold were studied in 20 subjects. Neck pressure pain threshold were recorded 3, 6, 9, 12 and 15 hours group, and evaluated by pressure algometry to Trapezius muscle, Sternocleidomastoidius muscle, Suboccipitalis muscle and Temporalis muscle. Neck pressure pain threshold was significantly larger in 15 hours group(p<.05). But relation between neck pressure pain threshold in male group and female group were not significant differences(p>.05).

This study was undertaken to investigate the correlations bite force and the electromyographic activities of masticatory muscle in deepbite, using the T-Scan system and electromyograph. The subjects of this study consisted of two groups ; one of 20 individuals with normal occlusion, the other group of 30 with deepbite. The deepbite was composed of Class I deepbite(male 9, female 7) and Clas II div. 1 deepbite(male 8, female 6). The obtained results of this study were as follows : 1. The maximum bite force was 155.93 N in normal occlusion, 165.11 N in Class I deepbite group, 111.55 N in Class II div. 1 deepbite group. 2. The greater !he number of tooth contacts, the more the bite force increased in all groups. 3. During maximum clenching, masseter and ant. temporailsmuscle activity of normal and Class I deepbite group were significantly higher than that of Class II div. 1 deepbite group, and the activity of masseter muscle was higher than that of ant. temporalis muscle in all groups. 4. The greater the maximum bite force, the more the muscle activities increased in all groups.

악구강계의 질환을 진단하고 치료후의 예후를 판정하기 위하여 maximal clenching시에 측정된 tooth contacts의 수와 분포가 이용되어 왔다. 그러나 maximal clenching시 반복된 tooth contacts의 측정은 저작근 피로등 문제점을 가지고 있다. 본연구는 건강한 성인 15명을 대상으로 maximal clenching 및 habitual clenching시 T-Scan system을 이용하여 치아접촉 수와 접촉시간을 측정, 비교 검토하여 habitual clenching을 이용한 방법이 Tooth contacts의 연구에 이용될 수 있는지를 확인 하는데 목적이 있으며, 연구결과는 다음과 같다. 1. Habitual clenching시 upright, semisupine position에서의 전측두근의 근활성은 maximal clenching시의 64.5%, 61.9% 및 73.3%로 나타났다. 2. Maximal clenching시 치아접촉 수와 접촉시간은 16.82개 및 0.429초로 나타났으며 habitual clenching시에는 11.65개 및 0.177초로 나타났다. 3. 치아접촉수와 접촉시간은 체위에 따라 크게 변화되지 않았다. 4. 치아접촉수와 접촉시간의 측정시에 habitual clenching을 이용하는 방법이 maximal clenching을 이용하는 방법보다 재현성이 더 높은 것으로 나타났다. 5. Tooth contacts의 연구시 habitual clenching을 기준으로 사용할 수 있다.

Generally, the totally paralyzed face can never be made normal by any of the current methods of reconstruction. Careful selection of patients based on sound judgment of what can and cannot be achieved by the proposed surgical technique is paramount to a successful operation and a satisfied patient. The results are related to time of delayed between injury and repair ; the shorter the delay the better are the results. The objectives in correcting facial paralysis are to achieve normal appearance at rest ; symmetry with voluntary motion ; control of the ocular, oral, and nasal sphincter ; symmetry with involuntary emotion and controlled balance when expressing when expressing emotion ; and no significant functional deficit secondary to the reconstructive surgery. It must be employed a number of concepts, for treatment of the paralyzed face by surgeon, depending on the cause, time interval, and wound characteristics, as well as the availability of and necessity for neuromuscular substitution. Nerve grafts, crossovers, muscle transfers, free muscle and nerve-muscle grafts, micronuerovascular muscle transfers, and regional muscle transposition are the principal methods being developed. We applied the temporal musle transposition for reanimation of unilatrally paralyzed faces for long times on two patients. The results of muscle transposition can be enhanced by the patient's learning to activate the transposed muscle by voluntary effort, and are best in patients who are motivated to learn the necessary motor-sensory coordination techniques.

The purpose of this study was to standardize and classify the coordination pattern among the left and right masseter and anterior temporal muscles, in terms of integrated EMG values per stroke during gum chewing in normal subjects. In this study, 20 normal subjects were selected to chew a piece of gum and integrated EMG from middle portion of the masseter and anterior temporal muscles on both sides were recorded 20 times during each of the right and left chewing respectively. And the Bioelectric Processor Model EM2 (Myo-tronies Research, Inc., U.S.A.) with the surface electrodes was used to record the EMG activity during all experimental procedures. The results were as follows; 1. In all subjects, the chewing side masseter muscle was predominantly active among the four muscles examined. 2. The integrated EMG value of the middle of masseter muscle was significantly predominant than those of the anterior temporal muscle (p<0.0001) on the chewing side, but no significant predominant was observed on the nonchewing side (p<0.98). 3. In comparison with same muscles on the chewing and nonchewing side, low correlation coefficient was found between the middle of masseter muscles (R=0.317), but high correlation coefficient was found between the anterior temporal muscles (R=0.738). Between two muscles on the same side, there were significant correlation in the chewing (R=0.557) and nonchewing side (R=0.625). 4. In the coordination patterns among four muscles examined, distinct individual differences were found, but in an identical subject one fixed pattern appeared with significant reproducibility.

Snapping triceps syndrome is a rare disease in which medial head of triceps dislocates over the medial epicondyle during elbow flexion. It is difficult to diagnose the snapping triceps syndrome, because that this syndrome is frequently misdiagnosed as other elbow disease such as ulnarnerve dislocation. The dynamic ultrasonographic imaging allows continual visualization of the ulnar nerve and triceps muscle throughout active elbow flexion and extension. We report two patients of snapping triceps syndrome who were diagnosed with the use of dynamic ultrasonography and treated with ulnar nerve anterior transposition and repositioning or resectioning of medial head of triceps.

Objective: To compare the electromyographic activity of masseter and temporal muscles between bruxers and nonbruxers in adult and adolescent patients. Material and Methods: The samples composed of the surface electromyography (EMG) recordings obtained from the orthodontic patients. Sixty-eight patients who had bruxsim habit (43 female and 25 male) were divided into four groups according to their age and gender. Control groups consisted of 79 patients who had not bruxism habit. EMG of the masseter muscle and anterior temporal muscle were recorded before treatment in clenching at maximum intercuspation. The ratio of temporal and masseter muscle activity (T/M ratio) was compared between bruxers and nonbruxers in adult and adolescent patients. Results: EMG of masseter muscle and temporal muscle were significantly higher in adult male bruxism group than control. T/M ratio in adult male bruxism group was significantly lower than in adult male nonbruxism group. However, there was no significant difference in T/M ratio between adolescent bruxism group and adolescent nonbruxism group. Conclusions: The balance in the activity of the masseter and temporal muscles may not differ between bruxers and nonbruxers during adolescent periods. However, in adult period, the masseter muscle activity against temporal muscle is greater in males with bruxism habit compared to non-bruxer.
