Objectives : This research was conducted to find the subjective symptoms of musculoskeletal system for main jobs and job posture. Methods : A survey was conducted from September 15, 2011 to October 7, 2011 and 357 dental hygienists were responded. The survey was consisted of the working environment and medical equipments, psycho-social characteristics, health habits and education, job posture, subjective symptoms of musculoskeletal system pain, and so on. Results : In the survey on the frequency of job posture of dental hygienists by jobs, said they cast down or tilt their head by 15 degrees or more or twist or bend their back. The result of the analysis on the subjective symptoms of musculoskeletal system by main job showed that they experienced a pain in neck, shoulder, and back, although the order differed. The order of subjective symptoms of musculoskeletal system for casting down or turning head by 15 degrees or more, twisting or bending back, having shoulders not parallel to the ground, sitting at the end of a chair, and supporting the whole body with one leg or pressing on a pedal for treatment was from the shoulders to the neck to the back. The order of subjective symptoms of musculoskeletal system for having arms too far from the body or hunching for treatment and bending wrists inward or outward for treatment was from the shoulders to the back to the neck. Conclusions : Due to the characteristics of the job which requires one to have a proper view of a patient's oral cavity, most of the postures included casting down of head or bending of back. Therefore a development of new postures is needed to replace the existing job postures which pressure the musculoskeletal system. And shift rotation can be used as a preventive measure.

Infant formula in nursing bottle, with inappropriate feeding habits, is major factor associated with the development of nursing caries. Although each infant formula has different carbohydrate and protein composition, studies comparing cariogenic potential of many Korean-branded infant formulas are deficient. In addition, it is on the point of being difficult to evaluate the cariogenecity of milk due to development of many infant formulas. In this study, to evaluate the cariogenic potential of many infant formulas, after oral rinse with six Korean-branded infant formulas(three milk based formulas, one soy based formula and two specific formulas for infants with allergy to milk protein and with lactose intolerance) for ten adult volunteers(eight males and two females), plaque pH change was measured with In vivo/In vitro combination technique and results were as follows. 1. All six different kinds of Korean-branded commercial infant formulas dropped the plaque pH significantly(p<0.05) and at an hour after rinse, plaque pH was not recovered in most of subjects. 2. Soy based infant formula and casein-hydrolyzated infant formula containing no casein dropped the plaque pH significantly more than milk based infant formula containing casein (p<0.05). 3. In the milk protein of infant formulas, casein had more effect on buffering the pH change of the infant formula than whey protein and casein-hydrolyzated infant formula had a reduced effect of casein. 4. In infant formulas with similar protein composition, infant formula containing sucrose dropped plaque pH more than infant formula containing lactose, but there was no significant difference (p>0.05).

Allergic inflammatory disease has been increased by abnormal lifestyle and food habits. Especially, prevalence of atopic dermatitis (AD) has been elevated and treatment of AD has not been unclear. Red sweet pepper (RSP), named as Capsicum annuum L, has been known as having pharmacological effects such as antioxidant, detoxification and antibacterial effects. However, the beneficial effect of ethanolic extract of RSP on AD has not been partly examined yet. Therefore, the aim of this study was to investigate anti-inflammatory effects of RSP on AD in vitro and in vivo models. The treatment of RSP inhibited the secretion of inflammatory cytokine such as interleukin (IL)-6 and IL-8 in tumor necrosis factor (TNF)-${\alpha}$ and interferon (IFN)-${\gamma}$-stimulated human keratinocyte (HaCaT cell). Also, RSP extract regulated 2,4-dinitroflorobenzene (DNFB)-induced AD-like skin lesions in BALB/c mice. Oral administration of RSP ameliorated DNFB-induced AD-like symptoms. In presented results indicated that RSP inhibited inflammatory cytokines in HaCaT cell and ameliorated AD-like skin lesion through suppression of symptom of DNFB-induced skin inflammation. Thus, RSP might be a potential therapeutic agent for AD.

Objectives : This study aims to report 3 cases of systemic atopic dermatitis improved by Korean medicine hospitalization care. Methods : Unlike outpatients, inpatients were supervised their lifestyle including dietary habits by physicians every morning and daily treated with acupuncture, herbal medicine including Bangpungtongseongsan-gagam, and Hwangryunhaedok-tang wet dressing therapy during all week. For dressing preparation, Hwangryunhaedok-tang was used to skin lesion except face. Mixed decoction of Lonicerae Flos and Forsythiae Fructus was used to facial lesion. Hwangryunhaedok-tang pharmacopuncture was injected to 2 patients. Western oral medicine and injection such as antihistamine or corticosteroids were prescribed by physician depending on each patient's condition. Symptoms were assessed with SCORAD index, IGA, and taking photos. Results : All patients showed the decrease in SCORAD index, IGA, skin lesion amelioration, and patient-subjective improvement. As time passes, dependence on western treatment also decreased and patients were able to endure pruritus without antihistamine injection during hospitalization. Conclusions : This study suggests that Korean medicine hospitalization care including acupuncture, herbal medicine, external therapy is effective for improving atopic dermatitis through decrease SCORAD index, IGA and ameliorating skin lesion.

Background: Obesity and dental caries have common risk factors such as food intake, eating habits, and lifestyle. Nevertheless, there has been no consensus on the significant association between obesity and dental caries, and additional studies are needed. We investigated the relationship between obesity and dental caries in some college students in this pilot study. Methods: Forty-two obese college students (body mass index [BMI]≥25) registered at a University Obesity Clinic and 19 normal students (18.5≤BMI<25) were recruited. Oral examinations were conducted, and anthropometric data and blood samples were collected. The blood concentrations of low-density lipoprotein (LDL), high-density lipoprotein, and triglyceride were also measured. After controlling for dental plaque index, a univariate analysis of dental caries indicators related to obesity was performed; partial correlation analysis was also conducted. A nonparametric test was used for the analysis of gender-related trends due to the limited number of participants. Results: The obese group had significantly fewer missing teeth (p=0.014), missing surfaces (p=0.035), filled surfaces (p=0.038), and decayed-missing-filled surfaces (p=0.020) than the normal group. There was no difference between the males in the normal and obese groups. The females in the obese group had significantly fewer missing teeth (p=0.003), missing surfaces (p=0.003), and decayed-missing-filled surfaces (p=0.046). Partial correlation analysis showed a weak negative correlation (r=-0.256) between the blood LDL concentration and decayed-missing-filled teeth. The other obesity and dental caries indicators were not correlated. Conclusion:The blood cholesterol concentration had a negative relationship with dental caries, and there were fewer cases of dental caries in the obese group in this study. However, it is important to clarify the relationship between obesity and dental caries through a dietary survey or additional investigations considering other confounding factors.

교정치료 중 구강 내 환경 변화를 파악하기 위하여 교정치료 시작 후 24개월까지의 임상적 구강위생지수 및 타액, 구강 내 미생물의 변화양상을 평가하였다. 30명의 환자를 대상으로 하여, 임상적 구강위생지수(DMFS [decayed, missing and filled surfaces], O'Leary's plaque index, plaque pH), 타액의 변화(비자극/자극시의 타액량, 완충능(buffer capacity), pH, 잠혈(occult blood)류량, 구강 내 미생물(Streptococcus mutans, Lactobacillus) 변화를 파악하였다. 추가적으로 설문지를 이용하여 구강위생관리 및 식습관을 평가하였다. 분산분석, 회귀분석 및 Spearman의 상관분석을 통해 데이터를 분석하였다. 교정치료 도중 DMFS 값은 유의성있게 증가한 반면, plaque index는 감소하였고, plaque pH는 산성을 나타내었다 (p = 0.23). 비자극 시 타액량은 치료 중 유의성있게 변화하였으며 (p = 0.13), 자극 시의 타액량은 여성에서 장치 부착 이후 증가하는 양상을 보였다. Buffer capacity는 남성에서 치료 도중 감소되었으며, 타액의 pH는 유지되었다. 구강 내 미생물 및 잠혈류량은 고위험 수준까지 증가하였으며 성별의 차이는 나타나지 않았다 (p > 0.05). 치료 전 plaque와 구강위생용품의 사용 (r = 0.429; p = 0.018), 최종 DMFS와 비자극 시의 타액량 (r = -0.372; p = 0.043) 간에 뚜렷한 상관관계가 확인되었다. 교정장치의 부착으로 인해 구강 내 미생물은 증가하고, plaque pH는 산성화되어 치주조직의 손상이 일어나게 되었다. 또한 Buffer capacity는 변하지만, 치료 기간중의 타액의 pH는 유지되었다.

This study was conducted to identify actual dental care status, levels of knowledge, attitudes, and behaviors about dental health, and dental health conditions in elementary students; and examine the relationships between the levels of knowledge, attitudes, behaviors, and dental health conditions for 427 students in their sixth grades from six elementary schools in Pusan area from November 1st to December 5th, 2002. The data was collected through a structured study questionnaire and through dental checkups by dentists and was analyzed into frequency, percentage, mean, standard deviation, t-test, one-way ANOVA and Pearson's correlation analysis using SPSS program. The main results of this study were summarized as follows： 1) The levels of knowledge, attitudes, behaviors about dental health was found to be high as mean score 18.75 points (64.7％) in knowledge, 17.86 points (59.5％) in attitudes, and 31.64 points (67.3％) in behaviors. Therefore they were found to care a lot about their dental health. The indices of dental health conditions were found to be low as mean score 0.87 pieces (3.1％) of treated teeth, 1.27 pieces (4.5％) of teeth to be treated, 7.64％ of the DMFT rate and 0.43 points (7.2％) of the simplified oral hygiene index. Therefore their condition of dental health was found to be very clean. 2) The relationships among the knowledge, attitudes, and behaviors about dental health showed a weak level of positive correlations. Among the conditions of dental health, treated teeth and the DMFT rate showed a moderate level of positive correlation； and treated teeth and the simplified oral hygiene index showed weak level of positive correlation. 3) The condition of dental health of the subjects of this study was found to be good and dental care was properly done when there was participation of parents and school health educators in dental care. It tells us that dental education is required not only for children but also for their parents. As there were significant correlations between knowledge, attitudes, and behaviors about children's dental heath, school health educators should encourage students to have continuous dental care habits for lifelong dental health with repetitive education, rather than to deliver simple knowledge to students during dental health education.

본 연구는 한국 성인 여성의 수면시간과 치주염과의 관련성을 확인하기 위해 국민건강영양조사 제 6기 2차년도(2014) 자료를 바탕으로, 만 19세 이상의 한국 성인 여성 총 3,292명을 대상으로 연구를 수행하였다. 대상자의 일반적 특성(연령, 교육수준, 소득수준, 당뇨, 고혈압, 비만)에 따라 치주염의 차이를 확인할 수 있었으며, 흡연과는 관련성이 없는 것으로 나타났다. 수면시간이 7시간 이상인 대상자에 비해 7시간 미만인 대상자의 치주염 위험도가 1.37배(crude OR, 1.37; 95% CI, 1.13~1.65) 높았다. 그러나 대상자의 일반적 특성(연령, 교육수준, 소득수준, 당뇨, 고혈압, 비만)을 보정한 후의 수면시간이 치주염에 미치는 영향력은 더 이상 유의하지 않았다. 따라서 후속연구에서는 두 요인의 직접적인 인과관계를 밝힐 수 있는 전향적 코호트 연구가 수행되어야 하며, 성인 여성의 적절한 수면습관을 도모하고 아울러 구강건강 증진을 위한 포괄적 건강증진 프로그램의 시행이 필요하다고 생각된다.
