The purpose of this study was to assess the level of awareness regarding the relationship between systemic diseases and oral health and the importance of education related to this association among dental patients, as well as to identify factors that affect the awareness of the relationship and the perceived need for education. This study was conducted from June 2016 to February 2017. Subjects of this study included outpatients (20-60 years old) from a dental clinic, and only patients who agreed to the survey were included. A total of 110 subjects were included, but the final analysis was based on 92 questionnaires, excluding questionnaires that were inaccurate. Survey questionnaires were completed by self-report and face-to-face interviews with a dental hygienist. The questionnaires covered basic information, awareness of the association between general and oral health, and experience with, and need for education related to, this association. Among the subjects, 48.9% were aware of the association between systemic diseases and oral health. A total of 39.1% of subjects had received education regarding the relationship between systemic diseases and oral health. Subjects who visited dental clinics regularly were 3.94 times (95% confidence intervals [CI]: 1.21-12.84) more likely to be aware of the association between oral health and disease compared with subjects who made only irregular visits to dental clinics. In addition, experience or education was significantly associated with awareness of the relationship between oral health and disease (odds ratio [OR]: 4.64, 95% CI: 1.54-13.93) and the need for education (OR: 3.98, 95% CI: 1.20-13.12). Thus, the dental professionals should provide education on the relationship between oral health and systemic disease in dental clinics to improve patients' awareness and oral health behaviors. These results can be used to strengthen education in the dental clinic.

To investigate the perception of the correlation between systemic diseases and oral health among some university students. The questionnaires were conducted on 485 students from 3 universities in Gwangju. As a result of the study, the female was higher than the male and was the highest in the fourth grade. Subjective health status, drinking status, smoking experience, and exercise were not significantly different in recognizing the association between systemic disease and oral health. The group with experience in oral health education recognized 3.18, and the group that practiced educational contents was highly recognized as 3.21. There was a significant difference between the two groups. Multiple regression analysis showed that major factor and grade factor influenced the perception of association between systemic disease and oral health. Therefore, it is necessary for university students to recognize the importance and necessity of periodical oral examinations. It is thought that the incidence of disease should be strengthened and enforced to recognize that there is a correlation with various diseases.

The purpose of this study was to evaluate the factors related to xerostomia in patients with systemic diseases, and the results were analyzed through t-test, ANOVA, and multiple linear regression analysis. There were 62 respondents (56.9%) who reported dry mouth and the season of the most severe dry mouth was reported to be the highest during winter. According to the analysis made in the relationship of xerostomia with the awareness of general health and health behavior, the group that understood their own health poorly, had more than two kinds of diseases, and had been administered more than two kinds of daily medication showed higher xerostomia. Also, those who experienced desperation, had high dryness in other parts of the body, and heavy snoring were more aware of xerostomia (p<0.05). According to the analysis made in the relationship between xerostomia and awareness of oral health state, the group that understood their oral health poorly and had pain in the oral mucous membrane and halitosis was more aware of xerostomia (p<0.05). According to the analysis made in the relationship between quality of life and xerostomia, the group that showed high level of problem in daily living and stress and were self-conscious and felt tense due to halitosis reported more xerostomia (p<0.05). Finally, xerostomia was most correlated with consciousness of the eyes of others due to halitosis followed by the number of transferred systemic diseases and stress level. Based on such results, xerostomia was understood to be an obstacle in maintaining favorable social life and health. Since xerostomia was shown to be related to the number of transferred systemic diseases, the dental professions are asked to further improve their understanding not only on oral health but also systemic diseases. Therefore, these efforts are expected to prevent xerostomia and reduce various complications caused by xerostomia.

당뇨병을 유발시키는 요인에는 여러 가지가 있다. 그 중에서 비만은 당뇨병 뿐 아니라 심혈관질환 등의 관련된 합병증의 주요 원인으로 악명이 높다. 실제로 2009년 대한 당뇨병학회지에 실린 논문에 의하면 제 2형 당뇨병환자의 80% 이상이 과체중 또는 비만으로 나타났다. 비만은 전신적인 지방의 총 양 이외에도 체내 지방의 분포에 따라서 그 위험도가 달라지는데, 특히 복부에 축적된 지방은 인슐린 저항성을 유발하여 심혈관질환의 위험을 더욱 증가시킨다.

배경: 심근 수축력과 더불어 전신저항은 개심술 후 적절한 심박출량을 유지하기 위한 매우 중요한 요인이다. 후부하의 변화를 비관혈적으로 평가할 수 있는지 알아 보고자 대동맥 혈류파형의 변화를 관찰하였다. 대상 및 방법: 개흉한 8마리의 잡견에서 연속파형 Doppler 심초음파를 이용하여 nitroprusside 단독 또는 epinephrine과의 병합투여 잔후로 상행 대동맥 혈류를 측정하였다. 결과: Nitroprusside의 투여로 동맥압과 전신저항은 약물의 투여량에 비례하여 감소함으로써(p<0.05 vs 기준치), 대동맥 혈류파형의 최고속도, 평균가속 및 분거리(속도시간적분$\times$심박동수)는 증가하였고, 가속시간은 짧아졌으며(p<0.05 vs 기준치), 가속시간/박출시간의 비는 변화가 없었다. Nitroprusside 투여로 인한 전신저항의 변화는 속도시간적분이나 Doppler 시간간격 지표보다는 최고속도(r=0.60, p=0.001)와 평균가속(r=0.52, p=0.003)과 상관관계가 있었다. Epinephrine과의 병합투여로 전신저항이 증가하지 않는 한 nitroprusside 단독투여에 비해서 최고속도, 평균가속 및 속도시간적분이 더 크게 증가했으나, 전신저항이 증가되면 이 Doppler 지표들은 감소하는 경향을 보였다. 결론: Doppler 심초음파를 이용하여 상행 대동맥 혈류파형의 최고속도와 평균가속을 연속적으로 측정함으로써 후부하의 변화를 비관혈적으로 평가할 수 있으리라 생각된다.

This study conducted a survey of 249 adults to determine the effect of oral health beliefs on total body health by mediating subjective oral health. The results showed that the subject's oral health belief averaged 3.75 points, the component of oral health belief was 3.41, the severity 3.73, the importance 4.22 and the benefit 4.19, and the subjective oral health was 3.77 points and the overall health was 3.06. Oral health belief and subjective oral health were found to have a correlation of wealth (r=-0.54, p<0.001), oral health belief and total body health also had a correlation of wealth(r=-0.30, p<0.001), subjective oral health and total body health had a relationship of justice(r=0.47, p<0.001). It was also found that oral health beliefs affect total body health by fully mediating subjective oral health. Based on these findings, it is thought that oral health education programs for adult oral health beliefs can be developed and utilized as basic data for comprehensive general health care, including oral health care, based on correct knowledge and attitudes.

Burning mouth syndrome (BMS) is defined as burning pain in the tongue or other oral mucous membrane associated with normal sign and laboratory findings at least 4 to 6 months. There are many factors that affect this condition and the pain characters are various among the sufferers, so it is difficult to diagnose exactly and treat properly. The cause of BMS is currently unknown. The etiology is presumed to be that it is related with local, systemic and psychogenic factor. The BMS is related with local factor such as allergic reaction, oral fungal infection(candidiasis), parafunctional oral habits and systemic factors such as diabetes mellitus, hypothyroidism, nutritional deficiencies(vitamin $B_{12}$, folic acid), hyposalivation and psychogenic factor such as depression, anxiety, cancerphobia. So clinicians must be aware of these factors and can give proper treatment options to patients. The management of BMS are pharmacologic management, cognitive behavioral therapy and psychotherapy treatment. Clonazepam, gabapentin, amitriptyline, alpha-lipoic acid and capsaicin are used to manage the BMS. Among these, topical clonazepam is reported that the effect is higher than systemic medication and the complications are rare. This case report is about some cases of the effect of topical clonazepam on BMS.

The purpose of this study was to investigate the effect of applying whole body vibration exercise at 30 Hz on the thickness and mechanical properties of the erector spinae. The study population included 24 adults (11 male and 13 female) in the N region. The subjects were divided into two groups, a 30Hz whole body vibration exercise(WG, n=12) and an LSG(12 subjects). Changes in the thickness and mechanical properties of the erector spinae were analyzed before the exercises and after four and eight weeks of exercises using a two-way repeated analysis of variance with a statistical significance level of α=0.05. When there was an interaction between the groups and measurement times, post hoc analyses were conducted at a statistical significance level of α=0.01. The thickness, frequency, stiffness and strain of the erector spinae muscles were significantly different in each time period and in the interaction between time period and the group (P<0.05), and recovery was significantly different only in each time period (P<0.05). Thus, 30Hz whole body vibration exercise had a positive effect on the thickness and mechanical properties of the erector spinae. The results of this preliminary study suggest that whole body vibration exercise may find a place as a lumbar stabilization exercise in clinical practice in the future.
