본 연구는 칸디다 알비칸스(C. albicans)에 대한 프로폴리스의 억제효과를 확인하고자 수행되었다. 프로폴리스는 양봉 꿀벌에서 채취하여 C. albicans는 37℃에서 액체 배지에서 2시간 배양 하였다. 항균 활성검삼를 위해서 생리식염수 (PBS), 3% 차아염소산나트륨 (NaOCl에), 0.1% 클로로헥시딘 (CHX), 프로 폴리스 추출물 (5 μL/ ㎖, 10 μL/ ㎖)에서 평가하 였다. C. albicans는 3%의 NaOCl, 0.1% CHX, 프로 폴리스(5 μL/ ㎖, 10 ㎕/ ㎖)에서 15, 14.5, 16, 17mm의 억제구간을 확인하 였다. 항균활성을 확인하기 위하여 집락형성을 분석한 결과, 3%의 NaOCl, 0.1 % CHX, 5 μL/ ㎖와 10 μL/ ㎖의 프로 폴리스 가 7, 7, 5, 7 로그지수가 감소를 보였다. C. albicans서는 10 μL/ ㎖의 프로폴리스에서 유의하게 억제되는 결과를 보여주었다. 이러한 결과를 통하여 프로폴리스는 구강 점막 질환에서 새로운 향균 약제가 될수 있는 것으로 생각된다. Propolis is an extremely safe natural antimicrobial substance that has been reported to have powerful antibacterial efficacy. The aim of this study was to evaluate the inhibitory effects of propolis against Candida albicans (C. albicans). Propolis was collected from the honey bee Apis mellifera. The strain of C. albicans was cultivated overnight in liquid media incubated at 37℃. The antimicrobial activity was investigated using phosphate buffered saline (PBS), 3% sodium hypochlorite (NaOCl), 0.1% chorhexidine (CHX), and propolis extracts (5 μl/ ml, 10 μl/ ml). C. albicans were sensitive to 3% NaOCl, 0.1% CHX, and propolis (5 μl/ ml, 10 μl/ ml) with zones of inhibition of 15, 14.5, 16, and 17 mm, respectively. The CFU of PBS, 3% NaOCl, 0.1% CHX, 5 μl/ ml and 10 μl/ ml of propolis led a 1, 7, 7, 5 and 7-log reduction. Among the groups tested, C. albicans was most sensitive to 10 μl/ ml of propolis, which showed the largest inhibition zones. Therefore, propolis can be a new antimicrobial therapy for oral mucosa disease in traditional medicine.

Objectives: The quest for a happy life is accompanied by an increase in social activities, living standards, and socioeconomic development, with individuals showing increased interest in health and esthetics. In the field of dentistry, not only prevention and treatment but also esthetics is gaining popularity. The aim of this study was to identify tooth color reduction and consequent patient satisfaction over a period of 6 months after office and home bleaching. Methods: Thirty subjects were divided using the convenience sampling method into two groups based on the bleaching agent used: 10% carbamide peroxide (CP10; home bleach) and 15% hydrogen peroxide (office bleach). CP10 was used at home in a tray for 2 h/day over 14 days, while 15% hydrogen peroxide was light-activated for 15 min, three times/session (total, 45 min). A control set of teeth without any bleaching treatment was used as reference. Shade evaluation was conducted using the Shade Eye NCC at baseline, 1 week, and 1 and 6 months after bleaching. Data were analyzed using the Mann- Whitney U test and the nonparametric Friedman test. Results: There were significant differences in tooth color before and after bleaching in both the home and office bleach groups, although intergroup differences were not observed. Although b* values after bleaching were lower than the original values, only slight tooth color reduction was observed at 6 months. ΔE*, which represents the overall change in color, at 1 and 6 months after bleaching was significantly different from that at baseline in the home bleach group, while it showed no significant differences in the office bleach group. According to a patient satisfaction survey, patient satisfaction significantly increased over time in the home bleach group, although it did not differ significantly between groups. Conclusions: Tooth whitening was observed after bleaching in both groups. However, slight color reduction was observed at 6 months after bleaching, and complete restoration to the color before bleaching did not occur; therefore, long-term observation of color reduction is required.

This research was conducted in order to examine the effect of tooth brushing room M elementary school in Changwon-city and to provide foundation data for effective project operation afterwards. The subjects were 347 students at the M elementary school where the tooth brushing room was being taught. The control group is 289 students at J elementary school where the tooth brushing room was not being taught. Research and analysis were carried out with structured survey and examination of decayed, missing, filled teeth (DMFT) index, decayed, missing, filled tooth surface (DMFS) index and O`leary index. The data was analysed by IBM SPSS Statistics ver. 19.0 program and the result is as follows: Depends on the tooth brushing room there was difference in statistical significance in filling teeth, sealant tooth surface, filling tooth surface, missing tooth surface, DMFS, O`leary index between the subject and control group. The less the frequency of brushing, the higher the DMFT index. Negative correlation was statistically significant. With incorrect brushing method, the less the frequency, the higher the DMFS index, Negative correlation was statistically significant. When the tooth brushing room was being implemented, O`leary index became low, negative correlation was statistically significant. As a result, in order to continue the effective operation of tooth brushing room, constant supervision and monitoring on students should be acutely needed by a principal, a school nurse and teachers in charge. Also together with a systemized cooperation between a health center and a nearby university``s related majors departments, the research proposes to execute constant oral health education and to expand the implementation project of the tooth brushing room at nearby elementary schools.

Objectives. The purpose of this study was to estimate the prevalence of musculoskeletal symptoms and work-related factors of these symptoms in dental hygienists. Methods. This questionnaire survey was conducted during May to August 2010 with 269 dental hygienists recruited as study subjects. The presence of musculoskeletal symptoms was assessed using a questionnaire of musculoskeletal symptoms from the Korea Occupational Safety Health Agency and work-related factors, and consisted of 7 job environmental factors and 4 job positions. Data analysis was performed using the chi square test and multiple logistic regression analysis using the SAS (ver 9.1) software. Results. The overall prevalence of musculoskeletal symptoms was 86.30% (233/269). The specific prevalence of musculoskeletal symptoms for different regions of the body were as follows: 64.44% in shoulders, 51.48% in legs/feet, 48.15% in waist, 47.41% in neck, 43.33% in hands/wrists/fingers, and 17.78% in arms/elbows. The related factors of musculoskeletal symptoms in dental hygienists were type of work place (OR=2.86, 95% CI: 1.07∼7.65 in dental clinics; reference group-dental hospital), number of patients per day (OR=6.10, 95% CI: 1.06∼35.04 in 15∼19 patients per day; reference group-below 10 patients per day), subjective physical burden (OR=3.06, 95% CI: 1.18∼7.94 in presence of physical burden; reference group-absence of physical burden) and location of operation (OR=9.60, 95% CI: 1.80∼51.19 in back to side position; reference group front to side position). Conclusions. More than four-fifths of the dental hygienists experienced musculoskeletal symptoms. Improvements of working environments in dental clinics, reasonable number of patients for operation, methods for reducing physical burden, correct working positions and procedures are needed to prevent musculoskeletal disease development in dental hygienists.
