Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 223~229
The aim of this study was to examine the effectiveness of oral health promotion program in a group of 9~18-year-old children and adolescents living in four orphanages in Dong-gu, Daejeon. The program was based on oral disease prevention program including oral health education, fluoride application and scaling every six months. Oral health status of total 109 orphans was examined by one dentists who were trained in 2010 Korean National Oral Health Survey. Dental caries index, community periodontal index and modified patient hygiene performance index (M-PHP) were checked using dental unit chair. Child oral health impact profile (COHIP) and subjective oral health recognition survey were carried out. Compared with data of 2010 national sample, the mean of decayed, missing and filled teeth showed no difference between the subjects and test values, but the means of decayed teeth, decayed surface, toothbrushing frequency of the subjects showed to become worse with advancing years in spite of oral health promotion program. COHIP, subjective oral health status showed lower than test values, too. In M-PHP and Calculus index, the subjects showed better by periodic oral health education and scaling. We suggest that oral health promotion program for orphans include oral disease treatment program as well as preventive program to improve oral health of orphans efficiently. And, oral health promotion program has to be connected with psychological support for improving quality of life of orphans.

In this research, the degree of depression and death orientation of the 332 female students majoring in dental hygiene at colleges located in Gyeongsangbuk-do Province were examined and analyzed through a structured self-administered questionnaire from May to July, 2012, for the purpose of improving their mental health. The results are as follows: 1. The degree of depression of the subject students majoring in dental hygiene was shown that 59.9%, 36.8%, 3.0%, and 0.3% of the students were in the normal group, mild depression group, moderate level of depression group, and severe depression group, respectively. 2. The grand mean and the standard deviation of the subjects'death orientation was
points. 3. The degree of depression of the subjects whose family's economic level was low, whose satisfaction with their family background was low, whose satisfaction level with their major was low, whose school records was low, who frequently thought about death, and who attempted suicide was high in a meaningful way, and death orientation was meaningfully low. In addition, those in the group with the experience of feeling suicidal were proved to have a significantly high degree of depression, and those without the experience of education about death had a low level of death orientation. 4. The degree of depression and death orientation had a positive correlation. When the study results above are combined, follow-up research needs to be conducted so that differentiated programs linked with the care for mental health for the formation of proper attitudes toward depression and death will be established to help students lead a positive life.

Jung, Eun-Ju ; Youn, Hye-Jeong ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 238~245
The purpose of this study was to examine the influence of the self-control of dental hygiene students on their stress and stress-coping style. The subjects in this study were dental hygiene students who were selected by convenience sampling from three different colleges. After data were gathered, the answer sheets from 561 respondents were analyzed. The findings of the study were as follows: 1. Concerning the level of self-control, the dental hygiene students got a mean of 3.22. As to self-control by grade, the juniors got the highest scores of 3.27 (p<0.05), and those who were under heavier stress were poorer at self-control (p<0.05). 2. In regard to stress-coping style, they got a mean of 3.28 and 3.34 in active coping and passive coping respectively. Passive coping was more prevailing, and the students whose economic status was higher made more use of active coping styles (p<0.001). There were statistically significant differences in active coping styles according to stress level (p<0.01) and the effect of stress on health (p<0.05). 3. Better self-control led to more frequent use of active coping styles. The above-mentioned findings imply that self-control is one of factors to affect stress coping. Therefore the development of counseling programs is required to step up the improvement of self-control.

Jeon, Eun-Suk ; Choi, Yu-Jin ; Hwang, Su-Hyun ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 246~253
The present study was carried out to evaluate the impacts of the qualities of dental medical services on service value, consumer satisfaction and consumer loyalty for 221 patients who visited 17 dental hospitals or clinics located in Busan and Ulsan using questionnaires and obtained the following conclusion. By gender, males had higher perceptions of para-language than females did in the qualities of the dental medical services, and by the level of education, college students and university graduates had higher perceptions of body language and physical appearance. Scores of service value, consumer satisfaction and customer loyalty were higher in males, college students and university graduates, and married patients, but those were not statistically significant. It turned out that the qualities of the dental medical services were correlated with service value, consumer satisfaction and consumer loyalty. As the perception of para-linguistic and verbal communication in the qualities of the medical services increased, service value increased; as the perception of verbal communication and physical appearance increased, consumer satisfaction increased; and as the perception of verbal communication, physical appearance and body language increased, consumer loyalty increased. To sum up the above findings, the qualities of dental medical services influence service value, consumer satisfaction and consumer loyalty, so in the future, it will be necessary to study quality dental medical services with which patients are satisfied.

Bae, Sung-Suk ; Lee, Myung-Sun ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 254~263
This study is to develop an evaluation index for infection control and to verify its validity by examining each set of weighted data collected from 121 infection control personnel at dental hospitals who agreed to the preliminary survey and advisory. The study was conducted from 14th December, 2010 to 31st January, 2011, and PASW Statistics 18.0 and AMOS 5.0 had been used for the statistical data analysis. As a result of the study, five evaluation factors with 21 sub-indicators have been identified at structural level, eight evaluation factors with 32 sub-indicators at processing level, and one evaluation fact with five sub-indicators at resulting level, total 14 evaluation factors with 58 sub-indicators throughout all levels. The path analysis added on the result that 'standard precautions (
)', 'infection control support system (
)', 'internal and external characteristics (
)' are exogenous variables that affect on other variables, and 'standard infection control (
)','Organization equipment management handwashing (
)', 'environmental infection control (
), 'personal protective equipment (
)', 'waste and laundry management (
)' are endogenous variables that are infulenced by others. The standardized metrics are more needed than anything else when examining on infection control. This study attempts to develop proper dental infection control metrics adequately adjusted for domestic circumstances, and therefore to contribute to effective systematic management and decision-making in infection control.

This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their practices by knowledge and attitude on radiation safety management (RSM). This study performed a survey on such an issue from July 2 to August 30, 2012 for 220 dental hygienists who worked in Busan, Gyeongnam areas. The data was analysed using the IBM SPSS Statistics 21.0 program. The results were as follows: As a result of the knowledge according to the general characteristics and RSM, a statistically meaningful difference was found according to the education on radiation and wearing apron. As for the attitude according to the general characteristics and RSM, a statistically meaningful difference was found according to the education on radiation and wearing apron. As to the practice according to the general characteristics and RSM, a statistically meaningful difference was found according to the education on radiation, wearing thermo luminescent dosimeter and wearing apron. When the analysis of safety management practice for radiation was conducted with the independent variables such as knowledge, altitude and health concerns about radiography, it turned out that the factors having an effect on the practice were altitude and health concerns by that order.

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.

Nam, Young-Shin ; Jang, Jae-Yeon ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 281~289
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.

Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 290~295
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 (
=0.05). The mean shear bond strength
SD in MPa was
in the Ni-Cr alloy group,
in the Y-TZP group,
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.

Lee, Hwa-Jeong ; Han, Soo-Yeon ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 296~303
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.

Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 304~313
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
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.

Koong, Hwa-Soo ; Ryu, Seung-Mi ; Hwang, Soo-Jeong ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 314~320
This study was aimed to investigate the motivators of smoking in 300 subjects using convenient extraction in one hospital. After informed consent, the survey that consisted of general characteristics, health behavior, stage of change, health behavior-related-perceived benefit, health behavior-related-perceived barrier, health behavior-related-family support, oral health behavior, subjective oral health and others was carried out. The smoking rate was higher in case of male (sex), high school graduates (education) and 2~3 million Korean won (KRW) (monthly income). The present smokers responded lower oral health behavior (p<0.001), lower health behavior-related-perceived benefit (p=0.021), higher health behavior- related-perceived barrier (p<0.001) and lower stage of change (p<0.001). The oral health related variables were not influenced by smoking. In logistic regression model, odds ratios in smoking were 0.378 in below average (health behavior-related-perceived barrier), 4.746 in below average (stage of change), 12.743 in male (sex) and 3.271 in 2~3 million KRW (monthly income/standard : over 3 million KRW). It was suggested that oral health related manpower should take account of not only smoking-related oral health but also motivators of smoking as to deliver effective no-smoking program.
Effects of Relative Lysyl Oxidase and Hydrogen Peroxide on Odontoblastic Differentiation
Lee, Hwa-Jeong ;
Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 321~329
Although it has been reported that lysyl oxidase (LOX) is involved in odontoblastic differentiation, the role of LOX on odontoblastic differentiation by hydrogen peroxide (
) have not been clarified. In the present study, we investigated whether
, reactive oxygen species (ROS), is modulated the messenger RNA (mRNA) expression and activity of LOX during odontoblastic differentiation of human dental pulp (HDP) cells. The mRNA expression was quantified by reverse transcriptase polymerase chain reaction (RT-PCR) analysis, and LOX enzyme activity was measured by high sensitive fluorescent assay. Expression of the odontoblastic differentiation marker genes were assessed in the presence and absence of specific small interfering RNAs (siRNAs) of the LOX and LOXL. The
-induced mRNA expression of LOX family was significant reduction of LOX, LOXL, and LOXL3 mRNA levels in HDP cells. LOX enzyme activity was increased at
0.3 mM for 24 hours. The mRNA expression of alkaline phosphatase (ALP), osteopontin (OPN), and osteocalcin (OCN) was inhibited by LOX- and LOXL-specific siRNAs whereas the mRNA expression of dentin matrix protein1 (DMP1), and dentin sialophosphoprotein (DSPP) was inhibited by LOX-specific siRNA. In LOX enzyme activity, siRNA-induced knockdown of both LOX and LOXL inhibited the total amine oxidase activity in HDP cells, as in the case of mRNA expression. In conclusion, the essential role of
on odontoblastic differentiation suggests that its regulation by LOX may have pharmacologic importance in HDP cells.

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.

Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 339~346
This study conducted questionnaire survey with 268 workers in Ulsan city to examine influencing factors about Oral behavior and Missing teeth of some workers. The collected data were analyzed using SPSS 12.0 program. The analysis results are as follows. 1. Oral health awareness was highest in thirties (p<0.01). For oral health sensitivity, female was higher than male (p<0.01). The lower the age was (p<0.05) and the higher the academic background was, there was statistically significant difference (p<0.01). 2. The lower the age was (p<0.001) and the higher the academic background was, the number of daily tooth brushing was more (p<0.001) and there was statistically significant difference. 3. The more the number of daily tooth brushing was, portion of Missing teeth was low (p<0.01). When oral hygiene devices such as interdental brush, dental floss etc. were used, portion of Missing teeth was low (p<0.01). When dental visit for prevention was made, portion of Missing teeth was low (p<0.05). In case of periodontal disease, portion of Missing teeth was high so that there was statistically significant difference (p<0.01). 4. There was positive relationship according to oral health awareness and oral health sensitivity, oral health status. The oral health status and Missing teeth had a negative effect relationship. Relationship between number of Tooth brushing and Missing teeth showed negative one. In summary, oral health education is needed to increase the motivation of industrial workers to control their basic dental disease.

Journal of dental hygiene science, volume 13, issue 3, 2013, Pages 347~353
This study was conducted to provide dental hygiene students with an opportunity which let them learn and have responsibility on bioethical perception by carrying out a survey for bioethical perception by personality types targeting 519 dental hygiene students. The study results were as follows: 1. Generally, in personality types, gender affects friendliness. Also, significant difference was shown in conscientiousness by age and practical experience. From finance point of view, significant difference was shown in neuroticism, extroversion, conscientiousness and openness, however, they did not satisfy test for equality of variances. 2. Generally, in bioethical perception, gender affects embryos right to life significantly (p <0.001) and considerable difference was appeared in intrauterine insemination by age. Significant differences were shown in embryos right to life by grade and whether students have practical experiences or not was the key factor which lead considerable difference in abortion. 3. In correlation of variances for personality types and bioethical perception, only friendliness and embryos right to life had weak correlation of 0.119. 4. In personality types affecting bioethical perception, friendlier personality had strong influence on embryos right to life. From this study, it can be concluded that bioethical perception could be affected by five personality types although they are not conclusive indicators which provide all the information.

Verruca vulgaris is one of the most frequent lesions of the skin. Evidences support that this lesion has strong association with low-risk human papillomavirus. Unlike skin lesion, oral verrucae vulgaris are not easily encountered and often misdiagnosed as squamous papilloma. Herein, we reported eight cases of oral verruca vulgaris and analyzed their clinicopathological features.
