  • The purpose of this study is to provide the basic date which is increase the number of revisits for scaling after analyzing factors that influence trend of dental revisits for 7 years. Research data was about 1,471 patients who visited S dental clinic in Seoul at 2007 for scaling. Data from January 2007 to December 2013 was collected. The subjects were divided into 3 groups by their trend in number of dental revisits for scaling: once, 2 times, 3~7 times. The data were analyzed using the chi-squire, independent-samples t-test and one-way ANOVA, binary logistic regression analysis. As a result, the trend of dental revisit for scaling is significantly decreased from first time to second time, and after 3rd time dental revisits were steadily continued. Factors affecting dental revisits for scaling are distance, family hospital, systemic disease, presence or absence of periodontal therapy. According to the results of the study, providing dental service in accordance with the patients' characteristics and increasing the dental revisits for scaling could give a positive influence to improvement of oral health.

  • The prevalence of periodontal disease was steadily increased. The best prevention methods for periodontal disease are teeth brushing and scaling. The purpose of this study was to investigate the status of scaling experience and related factors among some workers. Total 455 workers in 5 manufacturing companies in Gwangju were selected using convenience sampling method. General characteristics, work-related characteristics, oral health-related characteristics and scaling experience were collected by self-reported questionnaires. Chi-square tests, t-tests and multiple logistic regression analysis were performed to investigate the factors influencing the scaling experience using SPSS software. Statistical significance was defined as a p-value<0.05. The proportion of scaling experience during the past year was 47.0%. In simple analysis, age, current working position, number of oral disease, interest in oral health, use of secondary oral products, oral health screening use, oral health education experience and awareness of scaling inclusion in the National Health Insurance (NHI) coverage were associated with scaling experience. Finally, the odds ratios (ORs) for scaling experience were significantly higher in younger subjects (adjusted OR [aOR], 3.09; 95% confidence internal [CI], 1.60~5.96), assistant manager (aOR, 2.68; 95% CI, 1.55~4.63), subjects with high interest in oral health (aOR, 2.15; 95% CI, 1.02~4.52), subjects with oral health screening use (aOR, 2.76; 95% CI, 1.50~5.11) and awareness of scaling inclusion in the NHI coverage (aOR; 2.91, 95% CI, 1.80~4.72) in multiple logistic regression analysis. Scaling experience was relatively low (47.0%). The related factors with scaling experience were age, working position, use of screening and awareness of scaling inclusion in the NHI coverage. Considering these factors will increase the utilization rate of scaling.

  • This study was to figure out the influence of oral health behavior and periodontal status on their OHIP-14. Explained to 255 people who visited the scaling center of Dental Hygienics of a college in Gyeongbuk from March 7th to June 13th 2014 and it was agreed to perform. Result of dental plaque and calculus rate of those with no TBI were high; the less frequent do they teeth brushing the higher were their rate of dental plaque, bleeding and calculus, while their OHIP-14 was low. The rate of calculus of whom with no education on dental floss use and who do not use dental flosswas high. The more powerful for those with higher rate of dental plaque; while the lower was the rate of calculus the higher was OHIP-14. Therefore, the more do they brush their teeth and the lower are the rate of their calculus, the more positively has it been figured out to influence on the quality of their life of oral health. Consequently, public health program should be developed to educate them on the necessity of scaing on a regular basis and the cause calculus of occurrence, as well as a media through which they can easily participate in the program.

  • This article intended to examine the anti-plaque activity of 4 essential oils of Lavender, Tea tree, Eucalyptus, Lemongrass against Streptococcus mutans. In the results of measuring the anti-plaque effect against Streptococcus mutans, Minimum anti-adhesive concentration of Lavender oil was 1.0% and that of Tea tree, Eucalyptus, lemongrass essential oils was 0.5 %. Also, it was confirmed that the essential oils have the effect of inhibiting acid generation by Streptococcus mutans. It was confirmed that pH of the concentration was lowered by the acid generation under the MAC by measuring pH of the solution after incubating Streptococcus mutans and the essential oils in the thermostatic bath varying their concentration. From these results, the essential oils, particularly, Tea tree, Eucalyptus, Lemongrass essential oils are the natural material inhibiting the plaque generation and the potential that they can be used to develop the oral care products was confirmed.

  • This study takes road landscape of traditional Chinese Kangnam gardens in Suzhou as the object. It compares the relations and differences between preferences of Korean and Chinese on road landscapes with different rockery ratios, and studies the differences between Korean and Chinese's adjective visual characteristics of road landscape of traditional gardens and impacts of visual characteristics on preference. The following is the research process: Firstly, the theoretical survey of road landscape of traditional Chinese Kangnam gardens is conducted, pictures of the road landscape of gardens in Suzhou are taken, and 15 pictures are selected based on rockery ratio. Secondly, in order to grasp the visual preference and landscape characteristics of road landscape of garden in Suzhou, 15 pictures and 21 pairs of adjectives are adopted for the questionnaire survey. Thirdly, in order to grasp the differences between preferences of Korean and Chinese on road landscape of traditional Chinese Kangnam gardens, thet-test analysis is conducted. In order to grasp the impacts of rockery ratio on preference, and after the classification of landscape pictures based on rockery occupancy, the average analysis, factor analysis of results of questionnaire survey for Korean and Chinese are conducted respectively. In order to grasp the differences of incentives of landscape preference, the incentive analysis of results of questionnaire survey for Korean and Chinese is carried out. In order to grasp the impacts of various factors on the preference, The results are as follows: The results of analysis of differences between Korean and Chinese's preference on road landscape of traditional Chinese Kangnam gardens show that the overall preference of Chinese is higher than that of Korean. The results of the landscape preference analysis show that the ranking order of average value of Korean and Chinese's preference on rockery ratio categories is: medium ratio, very small ratio, small ratio, large ratio, very large ratio. The results of analysis of relations between rockery ratio of traditional Chinese Kangnam gardens and preference show that the preference increases as the rockery ratio decreases, and the rockery ratio variation causes greater impacts on Korean. Results of the analysis of visual characteristics, factors of visual characteristics of Koreans are "aesthetic factor", "comfort factor", "neat(orderly) factor", and "fun factor". The visual characteristics of Chinese has three factors, namely "psychological factor", "comfort factor", and "neat factor".

  • 치석에는 박리상피세포, 백혈구 등이 포함되어 있어 이들의 핵 내에 있는 DNA의 유전자형을 찾아내 개인식별을 할 수 있을 것으로 추정된다. 본 연구에서는 치석만으로 개인식별이 가능한지를 알아보고자 40명으로부터 채취한 치석을 증류수에 세척한 군과 세척하지 않은 군으로 나누어 DNA를 추출하고 중합효소연쇄반응법을 이용하여 증폭절편다형(AMP-FLPs)을 실시한 후 성별검사를 위한 X-Y homologous amelogenin gene과 유전자지문검사를 위한 STR유전좌위 LPL, F13B, Triplex(F13A01, FESFPS, vWA) 등 6개의 유전자를 검색하여 - X-Y homologous amelogenin gene과 LPL, F13B는 각각 증폭하였으며 F13A01, FESFPS, vWA 세 유전자는 동시에 증폭하였음 - 다음과 같은 결과를 얻었다. 1) X-Y homologous amelogenin gene 검색으로 세척군에서 27개의 검체 중 8개, 비세척군에서 13개 중 11개에서 성별검사가 가능하였다. 2) LPL유전자는 세척군, 비세척군에서 각각 27개 검체중 2개, 13개 검체 중 5개가 검색되었으며 3개의 대립유전자(10, 11, 12)와 4개의 유전자형 (10-10, 10-11, 10-12, 11-12)이 나타났다. 3) F13B유전자는 세척군, 비세척군에서 각각 27개 검체 중 1개, 13개 검체 중 4개가 검색되었으며 2개의 대립유전자(9, 10)와 2개의 유전자형(9-10, 10-10)을 관찰하였다. 4) F13A01유전자는 비세척군에서만 13개 검체 중 3개가 검색되었고 3개의 대립유전자(3.2, 4, 6)와 3개의 유전자형(3.2-3.2, 4-5, 4-6)을 관찰하였고, 세척군에서는 나타나지 않았다. 5) FESFPS유전자는 비세척군에서만 13개 검체 중 1개가 검색되었고 유전자 형은 11-12로 나타났다. 6) vWA유전자는 세척군, 비세척군에서 각각 1개씩 검색되었으며, 3개의 대립유전자형(14, 16, 17)와 2개의 유전자형(14-16, 14-17)을 관찰하였다. 이상의 결과를 종합해 볼 때, 치석은 X-Y homologous amelogenin gene증폭을 통한 성별검사와 단일 STR유전좌위 증폭을 통한 유전자지문형 검사에는 유용하나 복합 STR유전좌위의 검색에는 부적합한 것으로 나타났으며 법의학적시료로 응용이 가능한 것으로 사료된다.
