This research team extracted keywords from 953 papers published in the Journal of Dental Hygiene Science from 2001 to 2018 for keyword and centrality analyses using the Keyword Network Analysis method. Data were analyzed using Excel 2016 and NetMiner Version 4.4.1. By conducting a deeper analysis between keywords by overall keyword and time frame, we arrived at the following conclusions. For the 17 years considered for this study, the most frequently used words in a dental science paper were “Health,” “Oral,” “Hygiene,” and “Hygienist.” The words that form the center by connecting major words in the Journal of Dental Hygiene through the upper-degree centrality words were “Health,” “Dental,” “Oral,” “Hygiene,” and “Hygienist.” The upper betweenness centrality words were “Dental,” “Health,” “Oral,” “Hygiene,” and “Student.” Analysis results of the degree centrality words per period revealed “Health” (0.227), “Dental” (0.136), and “Hygiene” (0.136) for period 1; “Health” (0.242), “Dental” (0.177), and “Hygiene” (0.113) for period 2; “Health” (0.200), “Dental” (0.176), and “Oral” (0.082) for period 3; and “Dental” (0.235), “Health” (0.206), and “Oral” (0.147) for period 4. Analysis results of the betweenness centrality words per period revealed “Oral” (0.281) and “Health” (0.199) for period 1; “Dental” (0.205) and “Health” (0.169) for period 2, with the weight then dispersing to “Hygiene” (0.112), “Hygienist” (0.054), and “Oral” (0.053); “Health” (0.258) and “Dental” (0.246) for period 3; and “Oral” (0.364), “Health” (0.353), and “Dental” (0.333) for period 4. Based on the above results, we hope that further studies will be conducted in the future with diverse study subjects. 본 연구는 키워드 네트워크 분석 방법을 활용하여 치위생과학회지 2001년부터 2018년 3호까지 게재된 논문 953편의 키워드를 추출하여 연구 구조를 파악하기 위해 키워드분석과 핵심어를 파악하기 위해 중심성 분석을 실시하였다. 그리고 5년 단위로 1기를 2001년부터 2005년까지, 2기를2006년부터 2010년까지, 3기를 2011년부터 2015년까지, 4 기를 2016년부터 2018년까지로 구분하여 연구동향을 분석하여 다음과 같은 결론을 얻었다. 치위생과학회지에서 도출된 총 1,454개의 단어 중에서 17년간 치위생과학회지 투고논문에서 가장 많이 쓰인 단어는 ‘Health’이며 ‘Dental’, ‘Oral’, ‘Hygiene’, ‘Hygienist’에 관한 논의가 가장 활발하였음을 알 수 있었다. 중심성 분석을 통해 치위생과학회지에서 핵심이 되는 단어들과 연결되며 중심을 형성하고 있는단어들은 ‘Health’, ‘Dental’, ‘Oral’, ‘Hygiene’, ‘Hygienist’, ‘Behavior’ 등이며, 매개중심성 상위 단어들은‘Dental’, ‘Health’, ‘Oral’, ‘Hygiene’, ‘Student’ 등으로 나타났다. 시기별 연결중심성 핵심 키워드를 살펴본 결과, 1기에서는 Health (0.227), Dental (0.136), Hygiene (0.136) 등, 2기에서는 Health (0.242), Dental (0.177), Hygiene (0.113) 등, 3기에서는 Health (0.200), Dental (0.176), Oral (0.082) 등, 4기에서는 Dental (0.235), Health (0.206), Oral (0.147) 등의 단어들이 나타났다. 각 시기별로 매개중심성은 1기에서는 Oral (0.281)과 Health (0.199)의 매개중심성이 높게 나타났으며, 2기에서는 Dental (0.205)과 Health (0.169)가 높게 나와 매개역할의 비중이 높다가 Hygiene (0.112), Hygienist (0.054), Oral (0.053) 등으로 매개역할의 비중이 분산되는 것을 알 수 있었다. 3기에서는 Health (0.258)와 Dental (0.246)의 매개중심성이 높게 나타났으며, 4기에서는 Oral (0.364)과 Health (0.353), Dental (0.333)의 매개중심성이 높게 나타났다. 이상의 결과를 바탕으로 향후 치위생학 연구에 있어 학문 주제에 대한 다양성과 다각화를 모색하여 많은 연구가 이루어지길 기대한다.

The aim of this study was to identify bibliographic characteristics and research trends of articles published on the elderly people in dental hygiene. An analysis was done of 191 articles published from 1999 to 2017. Bibliographic characteristics were nine items such as publication journal, research design, research participants, number of researchers, data analysis method, keywords, research topic, and validity and reliability report. The collected data were analyzed using descriptive statistics of statistical program. First, the research on the elderly, which was published in dental hygiene, started to be published in 1999 and on going. Though major publications have been published in Journal of Korean Society of Dental Hygiene and Journal of Dental Hygiene Science, the kinds of journals are becoming diverse. Second, cross-sectional research was the most. Third, the elderly were the most studied subjects, but the criteria varied. Fourth, the number of authors was largest in order of two and three person. Fifth, data analysis method was in order of descriptive statistics, t-test, and ANOVA. Sixth, there were many duplication of keywords about oral, elderly, and health. Seventh, oral health behavior science was the most studied subject. Eighth, validity and reliability were reported at 27.4% and 51.6%, respectively. Ninth, only 15.7% of study was founded research funding. Based on the results of this study, we consider increase experimental research further. Therefore, it is recommeded that validity and reliability should be reported in research paper, and the keywords used in the field of dental hygiene should be agreed upon. 본 연구는 치위생학 분야에서 노인 관련 연구에 대한 동향을 파악함으로써 연구의 질적 향상과 함께 향후 노인 관련 연구에 대한 방향을 제시하기 위하여 치위생학 분야에서 노인과 관련된 주제로 발표된 학술논문을 검색하고 분석함으로써 다음과 같은 결론을 얻었다. 1999년부터 2017년까지 총 191편의 노인 관련 논문이 치위생학 분야에서 발표되었다. 대부분의 연구가 한국치위생학회지와 치위생과학회지에서 발표되었으며, 횡단연구가 144편으로 가장 많았으며 실험연구는 15편에 그쳤다. 연구대상자는 노인이 152편으로 가장 많았고 돌봄제공자에 대한 연구는 14편이었다. 연구자수는 2인이 65편으로 가장 많았고, 가장 많이 사용된 분석방법은 기술통계, t 검정, 분산분석, 회귀분석 순이었다. 가장 많이 나온 키워드는 구강과 노인, 건강 등이었으며 구강건강행동과학에 대한 주제가 87편, 임상치위생에 대한 주제가 43편이었다. 타당도를 보고한 연구는 42편, 신뢰도를 보고한 연구는 79편이었으며 연구비 수혜를 받은 연구는 30편으로 나타났다. 본 연구의 조사결과에 의하면 실험연구의 비율이 적은 것으로 나타났으며 타당도와 신뢰도를 보고한 연구논문의 편수가 매우 미비한 것으로 나타났다. 또한 같은 의미의 키워드가 매우 다양한 단어로 기재되어 있는 것으로 나타났다. 따라서 실험연구의 수행을 높이기 위한 노력이 필요하며 타당도와 신뢰도가 검증된 도구의 사용과 측정 후 논문에서 이에 대한 보고가 이루어져야 할 것으로 생각된다.

The purpose of this study was to examine the influence of the communication competence and empathy abilities of dental hygiene students on their interpersonal relationship abilities. The subjects in this study were 578 students who majored in dental hygiene at five randomly selected colleges. Out of the colleges, three were located in North Chungcheong province, and one was located in the city of Daejeon. The other one was located in South Gyeongsang province. Data were gathered using structured questionnaires from April 1 to May 7, 2013. The major findings of the study were as follows: 1. The respondents got a mean of 3.23±0.49, 85.80±10.12 and 83.27±8.37 in interpersonal relationship abilities,communication competence and empathy abilities respectively. 2. As for communication competence, empathy abilities and interpersonal relationship abilities by general characteristics, there were statistically significant differences according to age, academic year, clinical practice experience and satisfaction with major. 3. The relationship of communication competence and empathy abilities to interpersonal relationship abilities was analyzed, and interpersonal relationship abilities were found to have a strong significant positive correlation to communication competence, empathy abilities and the subfactors of the two. 4. As a result of analyzing which variables affected interpersonal relationship abilities,it`s found that interpersonal relationship abilities were under the influence of age, clinical practice experience, communication competence,empathy abilities. These variables made a 57.2% prediction of interpersonal relationship abilities. The above-mentioned findings suggest that communication competence and empathy abilities exerted an influence on interpersonal relationship abilities. Therefore curriculums and educational programs should be developed in consideration of these variables to ensure the stable college lives and successful relationship building of dental hygiene students who are on the way to adulthood and will serve as health care personnels in the future.

The purpose of this study was to investigate the shear bond strength between various commercial all-ceramic system core and veneering ceramics,and evaluate the clinical stability by comparing the conventional metal ceramic system. The test samples were divided into three groups: Ni-Cr alloy (metal bond), yttria-stabilized, tetragonal zirconia polycrystal (Y-TZP) (zirconia bond), lithium disilicate (lithium disilicate bond). The veneering porcelain recommended by the manufacturer for each type of material was fired to the core. After firing, the specimens were subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.50 mm/min until failure. Average shear strengths (mega pascal)were analyzed with a one-way analysis of variance and the Tukey test (α=0.05). The mean shear bond strength±SD in MPa was 44.79±2.31 in the Ni-Cr alloy group, 28.32±4.41 in the Y-TZP group, 15.91±1.39 in the Lithium disilicate group. The ANOVA showed a significant difference among groups (p<0.05). None of the all-ceramic system core and veneering ceramics could attain the high bond strength values of the metal ceramic combination.

The purpose of this study is to find out potential factors associated with the quality of life in South Korean senior people, on the basis of their oral health, so that it may provide basic reference materials in developing and assessing national policies for improving the quality of life in senior people. The data of 3,882 senior citizens who were at the Western age of 65 and up and got a dental checkup were selected from the first-, second- and third-year raw data of the 4th National Health and Nutrition Survey that were conducted from July 2007 to December 2009. And the statistical package SPSS 19.0 was employed to analyze the selected data. The findings of the study were as follows: The senior citizens whose remaining tooth was larger in number and who didn`t need partial or full denture lead a better quality of life. Therefore, dental loss without any prosthetic appliance has significant negative effects on the quality of life in senior people, so it is urgently demanded to try to increase the number of remaining teeth and apply dental prosthesis to senior people for recovery of their oral health.

This study aims to analyze the effects of tooth-brushing facilities (TBF) at middle schools that installed TBF in 2012 as part of the oral health project in Seongdong-gu, Seoul. The subjects were the first graders at A middle school that installed TBF previously and B middle school that installed TBF in 2012. The results are as follows: DMFT, DMFS and CPI didn`t show significant difference by schools (p>0.05), but code (0) was higher and code (2) was lower in female students than male students (p<0.05). As to PHP index, the students at A school with TBF indicated better oral hygiene (p<0.01). In the research on before and after installing TBF, the oral hygiene was improved significantly more after the installation than before (p <0.01). In the comparison on the oral health-related behavior, the percentage of not brushing after lunch was higher B school than A school and the frequency of toothbrushing after lunch was higher A school than B school (p<0.01). About the reasons why not to brush after lunch, there was difference in ``lack of the place`` as A school showed 2.6% while B school without TBF indicated 14.2% (p<0.01). About the changes of the oral health-related behavior before and after TBF installation, the percentage of not brushing after lunch increased from 78.7% to 83.8% after the installation. The average frequency of tooth-brushing after lunch for one week also decreased from 0.50 to 0.34 (p>0.05). Among the reasons why not to brush after lunch, ``lack of the place`` significantly reduced, but ``because other friends don``t do it`` increased greatly after the installation (p <0.05). Only with the improvement of oral health knowledge, we cannot expect either clinical or behavioral significance. Not only schools but policies of governmental agencies and financial support, cooperation of community-related groups for program development and evaluation will contribute altogether to helping teenagers to habitualize proper oral health management.

In order to explore microleakage in class V cavity based on different kinds of several dentin adhesive and composite resin, 2 kinds of composite resin was restored and exposed after applying 4 kinds of dentin adhesives. Deposited in methylene blue solution for 4 hours and cut in parallel with tooth longitudinal axis. By observing dye penetration level of enamel and dentin margins of each restored resin following conclusion was obtained. 1. In composite resin Filtek Z350XT Universal (3M/ESPE Dental Products, USA) in enamel margin, Easy Bond (3M/ESPE Dental Products) showed the lowest microleakage and this leakage was represented to be high in the order of Single Bond 2 (3M/ESPE Dental Products), Scotchbond Multi-Purpose (3M/ESPE Dental Products) and Cearfil SE Bond (Kuraray Medical Inc., Japan). In case of Filtek Z350XT Flowable (3M/ESPE Dental Products), Scotchbond Multi-Purpose showed the lowest microleakage and this leakage was represented to be high in the order of Single Bond 2, Clearfil SE Bond and Easy Bond. 2. In case of Filtek Z350XT Universal in dentin margin, Easy Bond showed the lowest microleakage and this leakage was represented to be high in the order of Scotchbond Multi-Purpose, Single Bond 2 and Clearfil SE Bond. In case of Filtek Z350XT Flowable, Scotchbond Multi-Purpose and Single Bond showed the lowest microleakage and this leakage was represented to be high in the order of Clearfil SE Bond and Easy Bond. 3. In all the groups excepting S-U group (Single Bond 2+Filtek Z350XT Universal), enamel margin showed more higher microleakage than that of dentin margin. 4. There was a difference between enamel and dentin margin among each group but it was not significant statistically (p>0.05). When summarizing this result, it is considered that composite resin and dentin adhesive could be applied selectively and particularly in case of applying 1-step self-etching dentin adhesive, this method would be advantageous for manipulation convenience and shortening of operation time.
인간치수세포에서 상아모세포의 분화과정 동안 Lysyl Oxidase Family의 역할
이화정 ( Hwa Jeong Lee ),한수연 ( Soo Yeon Han ) 한국치위생과학회 2013 치위생과학회지 Vol.13 No.3
Lysyl oxidase (LOX), extracellular matrix enzyme, is catalyzing lysine-derived crosslinks in collagen and elastin. Recently, several LOX-like proteins (LOXL, LOXL2, LOXL3 and LOXL4) have been identified in human but their specific functions are still largely unknown. The purpose of this study was to evaluate the function of the LOX family genes during odontoblastic differentiation of human dental pulp (HDP) cells induced with odontogenic supplement (OS). The messenger RNA (mRNA) expression of LOX family genes and differentiation markers was assessed by reverse transcriptase polymerase chain reaction analysis (RT-PCR). The formation of mineralization nodules was evaluated by alrizarin red S staining. Amine oxidase activity of HDP cells was measured by peroxidase-coupled fluormetric assay. The expressions of differentiation markers, such as alkaline phosphatase (ALP), osteopontin (OPN), osteocalcin (OCN), dentin matrix protein1 (DMP1), dentin sialophosphoprotein (DSPP) in HDP cells were increased after treatment with OS media. The LOX and LOXL mRNA expression were gradually increased in OS media, whereas LOX enzyme activities were markedly detected on day 7. The mRNA expression and LOX enzyme activity of collagen type I was very similar to the pattern of LOX gene. In this study, the expression of LOX and its isoforms, and activity of LOX were highly regulated during odontoblastic differentiation. Thus, these results suggest that LOX plays a key role in odontoblastic differentiation of HDP cells.
