An epidemiologic investigation was carried out to determine the prevalence of symptoms of temporomandibular disorders in college students that aged 19-31 years. 460 students were investigated with a questionnaire from September to December 2006. The obtained results were as follows : 1. The prevalence of symptoms of temporomandibular disorders was 80.6%. 2. The most frequently complained symptom was headache and joint sound was the next one without distinct difference between men and women. 3. While the rate of occurrence of symptom of acute malocclusion decreased with age in men, that of TMJ pain during chewing or speech increased with age in women. 4. Symptoms including TMJ pain during mouth opening, chewing or speech, TMJ fatigue and acute malocclusion occurred significantly more frequently in women than in men. Contributing factors including resting cheeks on hands, stressful state, gum chewing, insomnia and clenching occurred significantly more frequently in women than in men. 5. There was a highly significant relationship between symptoms and contributing factors including resting cheeks on hands, stressful state, unilateral chewing, insomnia and clenching. 6. There was a highly significant relationship between symptoms and general personality.
The purpose of this study was to assess the incidence of flare-ups among patients who received endodontic treatment and to examine the correlation with pre-operative and operative variables. Analysis was in two aspects (a) overall incidence of flare-ups as expressed by a percentage of all patients visits and (b) percentage of flare-ups that occurred as related to various factors suck as patient demo-graphics, diagnosis, and treatment procedures. 1. From the 840 teeth which were examined in this study, the total number of flare-ups was 13. 2. As to gender of patients, there was no significant difference in flare-ups. 3. As to tooth groups, there was no significant difference in flare-ups. 4. In the teeth with pre-operative symptom, there was a statistically significant higher incidence of flare-ups than the teeth without it. 5. In the teeth with apical periodontitis, there was a statistically significant higher incidence of flare-ups. 6. As to pulp and periapical status. non-vital teeth had a higher incidence as compared with vital teeth, irreversible pulpitis. 7. Multi-visit treatment resulted in the higher incidence of flare-ups than one visit treatment. 8. Re-treatment procedures had a statistically significant higher incidence of flare-ups than root canal treatment. In this study, overall percentages of flare-ups was $1.55\%$. It showed a statistically significant higher incidence related to pre-operative symptom, apical periodontitis, and re-treatment. There was no significant difference in flare-ups related to gender, tooth groups, and fistula.
The objective of this study was to investigate the relationship between health-risk factors and oral health in Korean adolescents. This cross-sectional study was based on the 9th Korea Youth Risk Behavior Web-Based Survey (2013). The final participation rate in the survey was 96.4%. of a Total of 72,435 adolescents (age, 12~18 years) who had participated in the survey, 66,951 adolescents (33,777 boys and 33,174 girls) were selected for analysis, after excluding those with missing data. The key variables were oral health factors (one or more of the six oral symptoms), general characteristics (five factors), and health-risk factors (five factors). After adjusting for the general characteristics, frequency analysis, ${\chi}^2-test$ using PASW Statistics ver. 18.0, and logistic regression analysis were performed to understand the effects of health risk-factors on the oral symptoms experienced by the study subjects. Subjects who answered 'Yes' for alcohol consumption had a 1.33 times higher risk of experiencing oral symptoms. Further, subjects who smoked were at a 1.2 times higher risk of experiencing oral symptoms. With regard to internet use, the risk of experiencing oral symptoms was 1.25 times higher for subjects who used the internet for 7 hours or more than for those who used it for less than 1 hour. Compared to those subjects who had not experienced violence in school, the odds ratio of subjects who had experienced it 3~4 times was 1.54-fold higher. The study found that health-risk factors were associated with oral symptom experience. Therefore, programs to understand health-risk factors and interventions should be developed for Korean adolescents and provided on a regular basis along with oral health education.

The circadian system represents a temporal order which is mediated by the mutual coupling of oscillators and by the synchronizing effects of zeitgebers. It is known that well-being of man depends partly on the maintenance of this order, and that repeated or long lasting disturbances to it such as shift work will Cause harmful effects. This study was a quasi-experimental study to test the effect of shift directions for the clinical nurses on the circadian rhythm. Fourteen nurses working at the general units of Y hospital were selected according to the established criteria. Fourteen subjects were assigned to a weekly shift but the directions of shift work were phase delay first and then phase advance or vice versa. Oral temperature, total sleeping time, frequency of sleep-wake cycle, fatigue, mental performance, and physical symptom were measured during these days except holidays. The data collection period was from April 26, 1993 to July 3, 1993. MANOVA and Wilcoxon signed rank test were used for statistical analysis. The results are summarized as follows. 1. Having worked on evening and night shifts in either phase delay or phase advance schedules, temperature rhythms of shift workers were gradually adapted to the new sleep-wake cycles. A complete adaptation to work on the night shift was achieved the sixth day of the night shift in the phase delay schedule compared to the partial adaptation to the work on the night shift in the phase advance schedule. Accordingly, by putting evening shift between day and night shifts, it will be possible for circadian rhythm to adapt easily to the night shift. 2. There were differences in the total sleeping time, frequency of steep-wake cycle, fatigue, and physical symptom except for mental performance between night shift and day, evening shift. This indicates further that shift workers working on the night shift have a hard time adapting to the shift work compared to the other shifts. 3. Evaluating all the acrophases of temperature rhythm either in phase delay or phase ad-vance schedules, it was shown that night to evening shift in the phase ad-vance schedule revealed the smallest phase move. Also phase advance schedule showed poorer adaptation to shift work than phase delay schedule in connection with total sleeping time, frequency of sleep-wake cycle, fatigue, mental performance, and physical symptom. It is suggested, taken together, these findings reflect that phase delay schedule facilitated the degree of adjustment to the shift work compared to the phase advance schedule.
Objectives : This studies were performed to investigate the correlation between the treatment effects and the changes of the thermal differences at the pre and post-treatment by using the digital infrared computer thermographic imaging (D.I.T.I) to the irritable colon syndrome 30 patients. Methods : The extracts of the gwakhyangjunggisan were administerd to the patients by oral method three times per day during four weeks. we selected the Chung-Wan($CV_{12}$), Chunchu($S_{25}$). Hapkok($LI_4$), Naegwan($P_6$), Yongdo($H_4$) acupoints and treated the patients two times per week during four weeks. One week later, we investigated the changes of the pressure pain around left side Pokkyol($SP_{14}$), the symptoms. and the skin temperature changes on Pokkyol($SP_{14}$) and Kimun($LR_{14}$) around, by using the D.I.T.I. Results : In the correlation between the severity of the pressure pain around left side Pokkyol($SP_{14}$) and the thermal differences on Pokkyol($SP_{14}$) and Kimun($LR_{14}$) around, before the treatment, the more the pain was severe, the more the skin temperature was differential significantly. In the correlation between the severity of the symptoms and the thermal differences on Pokkyol($SP_{14}$) and Kimun($LR_{14}$) around, before the treatment, the more the symptom was severe, the more the skin temperature was differential significantly. In the changes of the pressure pain around left side of Pokkyol($SP_{14}$), the improved were significantly higher than the unimproved. In the changes of the symptoms, the improved were significantly higher than the unimproved. In the correlation between the changes of the pressure pain around left side Pokkyol($SP_{14}$) and the changes of the thermal differences at the pre and post- treatment, the more the pain was improved, the more the thermal change was widened significantly. In the correlation between the changes of the symptoms and the changes of thermal differences at the pre and post-treatment, the more the symptom was improved. the more the thermal change was widened significantly. Conclusions : Above the results, the treatments was effective and the digital infrared computer thermographic imaging (D.I.T.I) was useful to prove the improvements of the pressure pain and the symptom with the irritable bowel syndrome patients.

Background: Locally advanced head and neck cancer is generally incurable and has a short survival rate. This study aimed to evaluate symptom relief, disease response, and acute toxicity after palliative hypo-fractionated radiotherapy and long-term survival in affected patients. Materials and Methods: Between January 2011 to December 2011, 80 patients who were histopathologically diagnosed as having stage III or stage IV head and neck squamous cell carcinoma based on Eastern Cooperative Oncology Group (ECOG) performance status 1-3, were offered palliative radiotherapy (20 Gy/5Fr/5 Days). Later these patients were evaluated on 30th day after completion of treatment for disease response based on World Health Organisation (WHO) criteria and palliation of symptoms using symptomatic response grading and acute toxicities by the Radiation Therapy Oncology Group (RTOG). Many patients were given post radiation therapy (RT) palliative chemotherapy for appropriate palliative care and a few patients were selected for further curative RT. The overall survival was also evaluated among this group of patients with last follow up date of 1st May, 2014. Results: The most common presenting complaint was pain followed by dysphagia. Most patients (60-70%) had appreciable relief in their presenting symptoms. A good response was observed in the majority following palliative RT; a few patients had progressive disease and some had stable and regressed disease. None of the patients experienced radiation toxicity that required hospital admission. Almost all showed grade one and two acute skin and mucosal toxicity one month after completion of treatment. The mean survival days for patients given only hypofractionated palliative RT was 307 days, those with post palliative RT and palliative chemotherapy was 390 days and patients who went on to receive further palliative RT and curative RT dose had significantly overall survival of 582 days. Conclusions: Advanced head and neck cancer should be identified for suitable palliative hypofractionated radiotherapy to achieve acceptable symptom relief in a great proportion of patients and should be followed by palliative chemotherapy or curative RT in suitable cases for long-term symptom-free survival.
Objectives : Aspergillosis of central nervous system(CNS) is a rare pathologic condition and it has been known to be difficult to diagnose and treat. We analyzed seven cases of central nervous system aspergillosis. The clinical characteristics, and the problems in diagnosis and treatment are discussed with review of previous literatures. Material and Methods : We reviewed the clinical records, radiological findings, and pathologic reports of 7 patients with aspergillosis which involved CNS. Results : Five patients were immunocompetent, and infection was related with previous operation in 4 of them. Two patients were immunocompromised and had no history of operation. Five patients had intracranial lesions and two had spinal lesions. Mean duration from the onset of initial symptom to pathologic diagnosis was 2.4 months. Mean duration from the previous operation to the onset of symptom was 9.3 months, and from the onset of symptom to diagnosis was 2.9 months in the patients who had histories of operation. All of them were treated with surgical procedures and intravenous and oral antifungal agents, resulting in cure in 6 cases. Mean duration of the treatment was 4.9 months. Conclusion : Because aspergillosis of CNS is a rare disease and is difficult to be differentiated from the pyogenic abscess or recurrent tumor, the pathologic diagnosis is very important for adequate treatment. Although the prognosis of aspergillosis of CNS has been known to be poor, adequate surgery for both diagnosis and treatment and antifungal chemotherapy resulted in good outcome.

Purpose: This study was performed to find out the effects of the Er:YAG laser (Key Laser) & Er,Cr:YSGG laser (Water Laser) on inflammatory tissues. Materials and Methods: It was performed on about 20 g, 6 weeks male ICR mouses. They were grouped into the control (negative), the inflammation induced 'control'(positive), Er,Cr:YSGG laser exposured group after inducing inflammation, Er:YAG lasere exposured group after inducing inflammation each 15 mouses. The mouses were applicated 0.5% DNFB 1 cc on ear skin twice a day for 4 days until symptom expression. After laser exposure, ear tissues were extracted and defined gene expression by RT-PCR. Then, tissue staining, lymphocytes observation, electromicroscophic laboratory were carried out. Results: Interleukin-$1{\beta}$ was expressed much less in the A-laser exposed group. Interleukin-$1{\beta}$ & Tumor Necrosis Factor-${\alpha}$ were expressed 7 times lesser in the A-laser exposed group. The number of Lymphocytes related to inflammation was decreased rapidly in the A-laser exposed group in vivo. he number of cavity recovered normal was a little bigger in the A-laser exposed group after 5 days Conclusion: The expression of IL-$1{\beta}$ & TNF-${\alpha}$, hitologic change, observation with electron microscope shows that Erbium laser exposure causes lesser inflammation with A-laser rather than B-laser.
Purpose : This study evaluated the impact of the presence and aspect of mandibular third molars to the mandible angle fracture or condyle fractures in Korean. Materials and Methods : A retrospective study was designed for patients attending the division of Oral and Maxillofacial Surgery, Kang-dong sacred heart hospital for treatment of mandibular fracture from January 2006 to September 2010. The primary variable was the presence of mandibular third molar and the secondary variable was the aspects of third molar impaction. Mandibular third molars were classified by the impaction depth and the available space as Pell & Gregory system. Outcome variables were the presence of mandibular angle fracture or condyle fracture. Also the source of trauma, age, sex were studied. Hospital charts, radiographs were used for study. Statistic analysis was done with descriptive statistics, the X2-test, linear-by-linear association. P value under 0.05 was considered significant statistically. Results : The number of involved patients was 86. The ratio of male to female patients was about 9:1 for angle fracture and 7:3 for condyle fracture. The most common source of trauma was assault for angle fracture and fall down for condyle fracture. The presence of mandibular third molar increased frequency of angle fracture and decreased condyle fracture with larger impaction depth. But available space of mandibular third molar did not show high association with angle or condyle fractures. Conclusion: Preventive extraction of mandibular third molar is recommended for patients with high risk of angle fracture. Male patients at their third decade or martial artists, police officer could be the case. But it is not recommended for patients with low risk of angle fracture and high risk of condyle fracture relatively. Elder female patients without any symptom on their third molar could be the case.

Purpose: We aimed to investigate the effect of oral Saccharomyces cerevisiae Hansen CBS 5926 therapy (Saccharomyces boulardii) on gastrointestinal symptoms and nutrition in gastrectomized patients. Materials and Methods: Ninety patients who underwent a gastrectomy due to early gastric cancer were randomly divided into case and control (placebo) groups and were given medicine or placebos for 12 weeks. The gastrointestinal symptom rating and the nutritional status were evaluated by using double blind methods at 4, 16, and 20 weeks after discharge. Results: The ratio of males to females was 2.3 : 1, and the mean age was $56.3{\pm}10.2$ years. The numbers of subtotal gastrectomies and total gastrectomies were 69 and 21, respectively. Fourteen (15.6%) patients dropped, of whom 5 belonged to the case group. Of the remaining 76 patients, those in the case group had higher levels of serum albumin (P=0.046). For patients who underwent subtotal gastrectomy (n=57), the case group had higher level of serum albumin (P=0.049). Conclusion: This double blind study showed that oral Saccharomyces boulardii therapy could improve the postoperative nutrition of gastrectomized patients because gastrectomized patients with oral Saccharomyces boulardii therapy had higher levels of serum albumin than the control group.
