This study is designed to evaluate the treatment outcome of occlusal stabilizing splint and to assess follow-up study of condylar bony changes using cone beam computed tomography(CBCT) in adolescents patients (12-19 years) with TMJ osteoarthritis(OA). 167 eroded condyles in 149 subjects were chosen among the patients who presented to the Department of Oral Medicine of Pasan National University Hospital, diagnosed as TMJ osteoarthritis by clinical exam, x-ray and CBCT from 2009 to 2012. They were treated conservatively with physical therapy, medication, behavioral therapy and occlusal stabilizing splint therapy. After average 9 months, CBCT was retaken and subjective symptoms and clinical findings were investigated. Condyle bony changes were classified by unchanged, less severe and more severe. The obtained results were as follow: 1. Pain, Noise, LOM(Limitation of motion) and MCO(Maximum comfortable opening) measurement of TMJ OA patients were markedly improved after conservative treatment. 2. In the occlusal stabilizing splint therapy group, Pain and LOM were statistically significant improved than non-occlusal stabilizing splint therapy group. 3. In the acute occlusal stabilizing splint therapy group, Pain and LOM were remarkably improved. 4. In comparison of CBCT1 and CBCT2 images, the transition of bone changes to lesser severe was most commonly in joint with erosive change. 5. In the non-occlusal stabilizing splint therapy group, the transition of condylar bone changes from erosion to more severe was many than occlusal stabilizing splint therapy group.

The aim of this study was to analyze physiological changes, clinical and subjective symptoms by different $N_2O$ concentrations and administration method. This study surveyed 65 men and women ages 19 to 35 and all subjects were healthy volunteers, with no contraindication for use of $N_2O$ sedation. The $N_2O$ sedation was carried out in a way that increases by 10 percent to one-minute interval or increases at once the desired level. Each method was required to reach 30 or 50 percent $N_2O$ concentration. The way to gradually raise the $N_2O$ concentration can reduce the risk by decreasing the pulse reduction rate at the same $N_2O$ concentration. $SpO_2$ has no statistical significance according to $N_2O$ concentration and method of administration. Pulse rate reduced significantly when 50% $N_2O$ increase at once during sedation and 100% $O_2$ after 5 minutes. The way to gradually raise the $N_2O$ concentration is safe for reducing pulse rate.

Choanal atresia may be membrane or bony, unilateral or bilateral. Approximately 90% of the choanal atresia are bony type. Unilateral choanal atresia often eludes the diagnosis because of the absence of subjective symptoms in the neonatal period. However, bilateral choanal atresia presents at birth with cyclic respiratory distress aggravated by feedings. So complete bilateral choanal atresia is considered as a neonatal emergency. Examinations for the diagnosis of chonal atresia include 1) attempt at passing a rubber catheter or probe through the patient s nose, 2) mirror examination of the nasopharynx, 3) digital examination of the nasopharynx, 4) X-ray examination after installation of radiopaque materal into the nasal cavity. But, computed tomography has become accepted method for evaluation of choanal atresia. Surgical repair of choanal atresia is accomplished via transnasal or transpalatal approach. Advantages of the transpalatal approach are improved exposure and the preservation of mucosal flap along the newly formed apertures. On the other hand, the transpalatal approach carries the risk of injury to the greater palatine neurovascular complex, and requires longer operative time. After careful physical and radiographic examinations, we accomplished the surgical repair of the complete bony bilateral choanal atresia via transpalatal approach without complications.

Hypophayngeal cancers are usually diagnosed in advanced stages and in many cases, they need total pharyngocervical esophagectomy and surgical reconstruction. Among many surgical reconstructive methods, jejunal free flap has anatomical and functional advantages such as tubed nature, peristaltic activity, excellent blood supply. In this study we analysed the surgical procedure and complications of jejunal free flap after total pharyngo-cervical esophagectomy. 20 cases performed jejunal free flap from 1995 to 2007 at Severance Hospital were reviewed. According to time of onset, early and late complications were reviewed. Surgical procedure was reviewed with operation record. Oral diet tolerance was reviewed on the basis of pharyngogram and subjective symptoms. The most common complication was stricture, and it occurred in 40% of cases and 63% of them were managed with conservative care. As early complication, fistula formation was all managed with conservative care. Oral feeding tolerance after jejunal free flap was 65% and 7 patients were tolerable to general diet. In our study, stricture was the most common complication and its management is important in post op oral diet tolerance.

Objectives: This study aimed to reveal the oral health conditions based on the dental health behaviors of a community-dwelling elderly. Methods: The subjects included 206 rural dwellers(100 men & 106 women) aged over 65 years old, who received dental health check-ups in the local public health center and its branches attached to 6 respective Myons of Chunchongnamdo Province, during the 2-month period from Jan. 1st to Feb. 28th, 2005. They were examined by dentists and given self-administered questionnaires asking about their dental heaith behaviors and subjective symptoms of gingival bleeding. Results: The oral health conditions based on dental health behavior showed that those who have not taken dental health service a year were found to have significantly greater number of missing teeth(p=0.002), DMFT(p=0.002) and CPITN(p=0.018), and those who have not observed intra-oral conditions a week to have significantly less number of filled teeth(p=0.002) and significantly greater number of missing teeth(p=0.000) and CPITN (p=0.000) than their respective counterparts. In terms of brushing, those who brushed their teeth below "3 times/day" were found to have significantly greater number of decayed teeth(p=0.000), missing teeth(p=0.000), DMFT(p=0.000) and CPITN(p=0.000) than their counterparts. In terms of time spent in brushing, those who spends "below 3 minutes" had significantly greater number of missing teeth(p=0.002) and DMFT(p=0.041), and significantly less number of filled teeth(p=0.036). According to the use of aid tools for cleaning teeth, the group who don't use them had significantly greater number of DMFT(p=0.041) and CPITN(p=0.018) than its counterpart. Classified by smoking habits, smoking groups had significantly greater number of decayed teeth(p=0.035) and CPITN(p=0.001) than non-smoking groups. Multiple regression analysis of the study data revealed that the significant factors influencing number of decayed teeth were number of brushing, sex and intra-oral observation (explanatory power of 14.2%). The significant factors for number of filled teeth were sex, intra-oral observation, use of aid tools, frequency of brushing, subjective health conditions and drinking of sweet beverages(explanatory power of 18.2%), those for number of missing teeth, number of brushing and age(explanatory power of 13.9%) those for DMFT, number of brushing, sex, use of dental service, age(explanatory power: 13.5%), and those for CPITN included smoking habits, use of dental service, use of aid tools (explanatory power: 10.8%). Conclusions: The study results revealed that the dental health behavior of the elderly population is in poor conditions and their consequent intra-oral health conditions are not good. To improve their oral conditions, public campaign and education will be needed to modify unhealthy dental health behaviors.

To evaluate the treatment outcome after conservative treatment in patients with TMJ disc displacement which is the most common temporomandibular joint arthropathy, the subjects were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Hospital, diagnosed as TMDs and treated with conservative methods from 1994 to 2006 for 13 years. 88 patients with diagnosis of DD/cR and 60 patients with diagnosis of DD/sR were selected as the experimental group and 74 patients with diagnosis of masticatory muscle disorder (MMD) were selected as the control group. Subjective symptoms and clinical findings were investigated to evaluate and compare the subjects' status at the first visit and the last visit. The results were as follows; 1. Pain, noise, LOM and MCO measurements of DD/cR, DD/sR and MMD groups were markedly improved after conservative treatments including behavior therapy, physical therapy, medication and splint therapy. 2. At the first visit, high score of pain in MMD group, high score of noise and large MCO measurement in DD/cR group and high LOM score in DD/sR group were observed. At the last visit, high score of noise and increased MCO measurement in DD/cR group and high score of pain and LOM in DD/sR group were observed. 3. Among the patients who complained joint sound at their first visit, about 60% showed complete loss of joint sound after conservative treatment 4. DD/cR and DD/sR groups showed satisfactory outcomes after conservative treatments such as behavior therapy, physical therapy, medication and splint therapy while MMD group showed similar treatment outcome irrespective of the treatment modality used. 5. There was no difference in treatment outcomes after conservative treatments when the subjects were classified and compared according to gender, age group and chronicity. 6. MMD showed satisfactory prognosis in 10 treatments in less than 6 months while DD showed favorable prognosis in 10-20 treatments for 6 months to 2 years.

The purpose of this study is to determine whether the clinical activity of patients with atopic dermatitis(AD) correlate with their serum cytokine levels. 86 patients with AD were treated with KHS, YMH and GHT. On each visit to the clinic, their skin status was evaluated using the SCORAD index and serum IL-4, $IFN-{\gamma}$, IL-12, IL-13, IL-2 and IL-10 were measured by ELISA. After oral administration of herbal medicine, patients' skin status and subjective parameters such as pruritus and sleeplessness were significantly improved according to regression analysis. In particular, patients aged 0-9 showed stronger responses to treatment, which implies that the younger patients aged, the easier the treatment by herbal formula became. In analysis of the type of chosen herbal medicines, YMH treated group showed a stronger response in reduction of affected lesion, intensity of a lesion and subjective symptoms, while KHS treated group showed the least reduction. The levels of serum IL-4, $IFN-{\gamma}$ and IL-2 correlated with disease activity. Moreover, in patients under 0-9, the IL-4 level had a corrleation with disease activity; patients under 10-19 showed a correlation between the levels of IL-4 and IL-2 and disease activity; patients under 20-29 showed a correlation between the levels of IL-2, IL-12 and $IFN-{\gamma}$ and disease activity. In comparison with chosen herbal medicines, the groups treated with YMH or GHT treated group showed a correlation between the levels of IL-4, IL-12 and IL-2 and disease activity while KHS treated group did not. Our data suggest that serum levels of IL-4 and IL-13 are good indicators of clinical improvement in treating AD.

This study examined the musculoskeletal symptom experience rate of some dental clinic workers and the factors influencing musculoskeletal symptoms according to their working environment and health habit. To that end, between March 9 and March 28, 2009, 200 workers at dental clinics in Chungcheong-do were surveyed using the self-administered questionnaire method. The data were analyzed using the SPSS WIN 12.0 program. The following conclusion was reached. 1. One-year musculoskeletal symptom experience rates of the subjects were categorized according to pans of the body: shoulders - 60.5%, lower limbs (legs, knees, and feet) - 57.0%, the lumbar region (back and waist) - 56.0%, the neck - 51.0% and the upper limbs (arms, wrists, and fingers) - 32.0%. 2. In general characteristics, a statistically significant difference was found according to gender, age, education, position, and oral health state. In working environments, a statistically significant difference was found according to work experience, the average daily number of patients handled, the average daily working hours, the posture for diagnosis, and satisfaction over work. In health habit, a statistically significant difference was found according to regular exercise, regular examination, and regular eating habit. 3. Factors influencing musculoskeletal symptoms were examined. As a result, influencing the musculoskeletal symptom experience were satisfaction over work among working environment characteristics, and regular exercise among health habit characteristics.

The mentophysical disease causes diseases in digestive, respiratory, circulating systems, including chronic pain, through combined reactions from different individual characteristics, mental stress and temperamental factors. The most common symptom related to orofacial area is pain and the contributive factors include biological, behavioral, environmental, social, emotional, recognitive factors. These factors affect the course of the symptom according to individual's character and human nature. In pain, sleep acts as a contributive factor, and pain could bring about sleep disturbance and vice versa. Deterioration of sleep quality would act as a factor that aggravates mental stress. Therefore, relatively accurate and simple mental examinations and sleep quality test should be carried out for the patients with symptoms related to orofacial area. This study evaluated the mental state in relation to the sleep quality which could affect orofacial pain. The number of poor sleeper was 18 in male subjects, and 1 in female subjects and PSQI global index was higher in male($6.11{\pm}2.38$) than female($4.67{\pm}2.18$). SCL-90-R index showed no sex difference. Poor sleeper showed significantly high value in SOM, O-C, I-S, ANX, PHOB, PSY, GSI, PST. When SCL-90-R T scores were compared according to sleep quality, higher the subjective sleep quality score, O-C and I-S showed significant increase. As sleep disturbances score increased, PAR, PSY, PST showed statistically significant increase. In comparison of SCL-90-R T score according to daytime dysfunction, statistically significant increase in DEP, ANX, HOS, PHOB, PAR, GSI was observed. Therefore, the quality of sleep and psychological status have a high correlation. This is likely to influence chronic pain in the orofacial field. As a result, clinicians treating orofacial pain should evaluate the sleep quality and psychological status of the patient. Further studies of larger sample sizes including various age, occupation, and pain groups are necessary in order to apply the results to clinical practice.
