This study is designed to compare the effect of a needle with the magnet on body. We took the skin temperature of the belly with digital infrared thermographic imaging while we sticked needle and apply magnets on L14. We made experiments on 40 healthy male volunteers for one month. We classified control group not acupuncture or magnet adhering(CON). acupuncture group on left and right L14(LA). and the permanent magnet group adhering to left and right(LM). And LM is divided into S-polar permanent magnet group(LMS) and N-polar permanent magnet group adhering to left and right L14(LMN). When we observed that temperature changed with time, the skin temperature of th belly in CON descended significantly but LM, LMS and LMN is not changed significantly. As mentioned above. we observed that the needles on L14 affected the change of temperature on the belly, and conjectured that the appliance of magnets had the same results. If the mechanism depends on the meridian of body and energy. we suppose that the appliance of magnets and needles has same effects.

Objectives : The purpose of this study was to examine whether or not Postural Yinyang Correction of TMJ(Temporomandibular joint) using Standard intraoral appliance could decrease chronic low back pain. Methods : We reviewed the medical records of 40 patients with TMJ disorder aged from 30 to 70 years from 124 patients who were treated in chronic low back pain at Department of Acupuncture & Moxibustion of Korean Medicine Hospital of Dong-Eui University from November $1^{st}$, 2015 to June $5^{th}$, 2016. The patients were divided into 2 groups: Group A and Group B. In Group A, we treated the patients with acupuncture, sweet bee venom treatment and FCST(Functional Cerebrospinal Therapy) through Standard intraoral appliance from ABA(Accurate Balancing Appliance), Full body exercise therapy, and Upper cervical alignment balance therapy. In Group B, we treated the patients with acupuncture and sweet bee venom treatment. To estimate the effectiveness in controlling pain, we analyzed the Visual analog scale(VAS). To evaluate functional change of patients, we analyzed the Oswestry low back disability questionnaire(ODI). Results : In both groups, VAS and ODI decreased significantly. In the VAS, the result of Group A is significantly more effective than that of Group B. In the ODI, the result of Group A is statistically less effective compared to that of Group B, but not significantly. Conclusions : According to the results, Postural Yinyang Correction of TMJ using Standard intraoral appliance may be effective treatment for low back pain, but the further researches are needed.

Ectopic eruption of the first permanent molar means the first permanent molar assumes an atypical path of eruption resulting in premature atypical resorption of the second primary molar. If the reversible eruption does not occur, early loss of the second primary molars results in space loss, mesial tipping of the first permanent molar, impaction of the second premolar, buccal segment crowding and overeruption of opposing tooth. The main objectives of treatment are (1) to prevent loss of the second deciduous molars so it can continue to serve as a space maintainer and (2) to regain lost arch length, allowing the second premolar to erupt into normal position. The optimal treatment approach depends on a number of factors including the clinical eruption status of /6/, the change in position of /6/, the amount of enamel ledge of /E/ entrapping /6/, the mobility of /E/, and the presence of pain or infection. Unilateral appliance to correct the mesial angulation of ectopic permanent first molars, as in the majority of the appliance designs, would produce a resultant force that would further enhance the space loss. A bilateral support similar to the holding arch design is recommended to maximize the anchorage. These case reports present the successful result of preserving space for the second premolar in treatment of ectopic eruption of the first permanent molar using Halterman appliance with bilateral anchorage on patients visiting department of pediatric dentistry in Samsung Medical Center.

Tolerances are defined as the allowable variations in the geometry and positioning of parts in a mechanical assembly for assuring its proper functionality. Tolerance analysis is the activity related to estimating the potential accumulated variation in assemblies. If the estimated variances go out of the specified ranges, it causes the quality problem. Thus, we should adjust the tolerances and this activity is called as tolerance design. In this paper, a case study on the accumulated tolerance analysis and design using Monte Carlo simulation is introduced, which is applied for developing a portable medical device. Using the simulation study, we can improve the assemblability and functionality of the product.

Objectives: The aim of our study was to report clinical improvement of a patient who suffered from Temporomandibular Disorder (TMD) being treated with Korean Medical treatments and Intraoral Balancing Appliance (IBA). Methods: During the admission period, the patient was treated with acupuncture, cupping, Korean Medicine, Chuna therapy and FCST (Functional Cerebrospinal Therapy) every day. And we observed patient's condition by Numeric Rating Scale (NRS), Pain Disability Index (PDI), EQ-5D-5L (Five-level EuroQol-5 dimensions), and assessment about range of motion(ROM) for temporomandibular joint and cervix. Results: After treated for 4 weeks, the patient's NRS, PDI, EQ-5D-5L and ROM were improved. Conclusions: Korean Medical treatments including FCST are estimated to be effective for patients with TMD. But the case was only one, so more cases and further research is needed to prove the effectiveness of the treatment.

The purposes of this study were to develop and introduce a novel intraoral appliance for bruxism composed of power switch and biofeedback device and further to examine inter- and intra-reliability of the appliance prior to clinical tests. The newly-developed appliance consisted of detection sensors, a central processing unit (CPU), a reactor and a storage unit and a displayer. Compact-sized, waterproof switches were selected as bruxism detection sensor and any sensor activation by clenching or grinding event was processed at the CPU and transmitted, by radio wave, to the reactor and storage unit and triggered auditory or vibratory signal, subsequently producing biofeedback to the patient with bruxism. The data on bruxing event in the storage unit can be displayed on the computer, making it possible analyzing frequency, duration and nature of bruxism. Cast models were obtained from ten volunteers with normal occlusion to evaluate reliability of the appliances. For inter-operator reliability on the intraoral appliances, each operator of the two fabricated the appliance for the same subject and compared the minimal contact forces provoking auditory biofeedback reaction in vertical, lateral and central directions. Intra-operator reliability was also investigated on the appliances made by a single operator at two separate times with an interval of two days. Conclusively, the newly-developed appliance is compact and safe to use in oral circumstance and easy to make. Furthermore, it had to be proven reliability excellent enough to apply in clinical settings. Thus, it is assumed that this appliance with the processor and the storage of data and auditory or vibratory biofeedback function is available and useful to analyze and control bruxism.

Objective: The purpose of this study was to clarify the effects of continuous force application for extrusive tipping movement and occlusal interference on periapical root resorption in the rat mandibular first molar. Methods: We constructed an appliance comprising a titanium screw implant with a cobalt-chromium post as the anchorage unit and a nickel-titanium closed coil spring (50 cN) as the active unit. Force was applied on the mandibular left first molar of rats for 8 (n = 10) and 15 days (n = 10; experimental groups), with the tooth in occlusion. Five rats were included as a non-treated control group to examine the body effect of the appliance. Active root resorption lacunae, identified using tartrate-resistant acid phosphatase, were evaluated in terms of the length, depth, and area. Results: The rat mandibular first molars were mesially tipped and extruded in the occlusal direction. This mesio-occlusal tipping movement and occlusion resulted in the formation of a compression zone and active root resorption lacunae in the distoapical third of the distal roots. However, there was no significant difference in the amount of root resorption between the two experimental groups. The control group did not exhibit any active root resorption lacunae. Conclusions: Periapical root resorption was induced by continuous extrusive tipping force and occlusal interference in rat mandibular molars. These data suggest that we orthodontists had better take care not to induce occlusal interference during our orthodontic treatment.
