To compare the stationary dental X-ray generator and the portable dental X-ray generator and to understand spatial radiation dose depended on locations by measuring spatial radiation dose of the portable dental X-ray generator. The researchers used an Ionization chamber to measure spatial radiation dose which was generated while applying X-ray radiation to real bone skull phantom with both portable and stationary dental X-ray generator. There were 4 measurement locations which were immediate anterior, right, left and posterior. Distance of measurement was 50 cm in every location and the recorded result is an average of two applications of X-ray radiation to the maxillary molar area under the condition of 70 kVp, 3 mA, 0.1 sec. Average spatial radiation dose of portable X-ray generator was
, much higher than that of stationary X-ray generator which was
(p<0.001). The result of the spatial radiation dose of the portable X-ray generator showed a huge difference depending on types of units which varied from
(p<0.05), also depending on the measurement location, immediate anterior resulted in the highest radiation dose of
and immediate right was the lowest of
. Immediate left and posterior, however, resulted in similar radiation dose which were
(p<0.01). With this result, we claim that usage of portable dental X-ray generator should be restricted to patients who can't move and exposure to radiation should be minimized by wearing lead-apron.

The aim of the study was to investigate the affecting factors on National Health Insurance coverage dental scaling experience. The self-reported survey for the adults living in Seoul, Gyeonggi province and Incheon had been progressed from February 10, 2014, to February 28, 2014, after receiving informed consents. And the 238 survey results had been analysed as the data of this study. The data analysis such as frequency analysis,
-test, and multi-logistic regression (p<0.05) for all collected survey data had been processed using IBM SPSS Statistics ver. 20.0. According to multiple logistic regression analysis, regular dental check-up (odds ratio [OR], 2.63; confidence interval [CI], 1.05~6.59) and dental scaling experience (OR, 3.06; CI, 1.09~8.54), monthly income (OR, 3.55; CI, 1.01~12.56) were the factors having statistically significant influence. Therefore, in order to increase of National health insurance dental scaling experience, it is necessary to increase awareness of the new dental scaling system through the promotion and oral health education about national health insurance dental scaling, and to emphasize the importance of dental Scaling by regular dental check-up.

Odontoclasts and osteoclasts resorb tooth root and alveolar bone, respectively. Many studies have focused on osteoclast formation in periodontitis, but effect of periodontitis on odontoclast formation is not clearly clarified. In this study, we observed formation of odontoclasts as well as osteoclasts in rats with ligature-induced periodontitis. To induce periodontitis, ligatures were placed around the first molars in left mandibles of rats. Rats were sacrificed at days 1, 3, and 10 after ligation. After tartrate resistant acid phosphatase (TRAP) staining in mandible section, the number of TRAP-positive odontoclasts and osteoclasts were histologically counted along the root and the alveolar bone surfaces of tooth, respectively. Odontoclasts increased until day 10 in mesial and furcation root surface, but did not increase in distal root surface. When compared odontoclast formation to osteoclast formation in mesial surface, osteoclasts peaked at day 3, and then decreased gradually, whereas odontoclasts were continuously increased until day 10. The number of odontoclasts was lower than that of osteoclasts before and after periodontitis induction. These indicate that periodontitis increased formation of odontoclasts as well as osteoclasts, but odontoclast formation occurs slower and weaker than that of osteoclasts.

This study attempted to identify the possibility of natural herbal extracts as an alternative, preventive agent of caries by comparing antimicrobial activities between natural herbal extracts and mouth rinsing solutions against Streptococcus mutans. Natural herbal plants were extracted with distilled water and ethanol, respectively, to measure the minimum growth inhibitory concentration of S. mutans depending on concentration, and among which, solvents showing high antimicrobial activity were selected to compare their antibiotic effects with those of mouth rinsing solutions. Also, to determine the concentration of natural medicinal herbs that can be used safely in the oral cavity, the extracts were treated to the normal gingival fibroblast cells depending on concentration in order to determine its cytotoxicity using MTT. In terms of the minimum growth inhibition concentration, the growth inhibition of S. mutans was more excellent in the ethanol extract than in the distilled water. When the minimum growth inhibition concentration was compared, Psoralea corylifolia of natural herbal ethanol extracts, and Hexamedine (Bukwang Pharm., Korea) of mouth rinsing solutions inhibited growth of S. mutans at the lowest concentration. When the minimum bactericidal concentration was compared, P. corylifolia of natural herbal extracts, and Hexamedine and Garglin (Dong-A Pharm., Korea) of mouth rinsing solutions eliminated S. mutans at a low concentration. The human gingival fibroblast was treated with natural herbal ethanol extracts at the minimum growth inhibition concentration of 10, 39, and
. As the result, no cytotoxicity was found. When this was treated at different minimum bactericidal concentrations, natural herbal ethanol extracts showed cytotoxicity except P. corylifolia.

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 aim of this study was to investigate the relationship between the oral health status of elderly under visiting health care and their oral health-related quality of life. The subjects were 300 elderly under visiting health care program over 65 years old in Asan city and they were interviewed. The result showed that average Geriatric Oral Health Assessment Index (GOHAI) score was 37.36 and the lowest scored question was 'never satisfied with the oral condition'. In GOHAI related to oral health behaviors, unmet dental treatment experience was statistically significant (p<0.001). In overall GOHAI, number of remaining teeth (p<0.001) and the age had statistical significance and men had higher score in pain and discomfort (p<0.05), under age of 74 limited function factors score was high (p<0.01). The number of remaining teeth had statistical significances in most factors except pain and discomfort (p<0.001). The factors affecting GOHAI were age (p<0.05), number of remaining teeth (p<0.001) and perceived health state (p<0.001). In order to improve oral health-related quality of life of elderly receiving visiting oral health care services, it is necessary to increase denture support by securing budgets and developing oral health promotion programs at the local government level.

The study was intended to investigate the factors affecting dental caries in adults. To that end, adults aged 19 years and older among 10,113 subjects who completed the health-related questionnaire, medical examination and nutrition surveys in the first year (2013) of the 6th Korea National Health and Nutritional Examination Survey, and 4,843 subjects categorized as patients with permanent teeth caries were included in the final analysis. The prevalence of dental caries in line with socio-economic aspects was found to be higher in men than in women. In view of education, the prevalence of dental caries was high in high school graduates, middle school graduates, college graduates and other advanced degree holders in the order named. Low monthly income earners showed the highest prevalence of dental caries. As for health-related lifestyles, the prevalence of dental caries was higher in smokers than in non-smokers. Obese subjects showed a little higher prevalence of dental caries compared to people of normal weight. Also, the prevalence was higher in those who failed to get oral examination than otherwise. Frequent daily toothbrushing and use of dental floss and interdental brush significantly decreased the prevalence of dental caries. In the logistic regression analysis with the presence or absence of dental caries employed as a dependent variable, gender, age, income level, smoking, oral examination and use of dental floss were found to serve as independent variables affecting dental caries. Therefore, Korean adults' socio-economic factors and lifestyles were proved to affect dental caries, which warrants some dental health programs and action plans designed to help lead healthy lifestyles whilst preventing dental caries and improving dental health in adults.

DOI : 10.17135/jdhs.2015.15.3.340
The purpose of this study is to analyze the factors of oral function associated with number of present teeth (NT) in Korean elderly adults. The research was designed as cross-sectional study using the data of the 4th Korea National Health and Nutritional Examination Survey, and the samples were selected by stratified clusters sampling. The subjects aged 55 to 84 years were 4,780 that joined the oral examination survey and questionnaires. The respective variables reflecting socioeconomic status, subjective health status and oral function factor were analyzed and their distributional differences were confirmed by complex sampling logistic regression analysis. Multivariable liner regression models considering covariates were applied to explain the associations between the number of present teeth and other variables. Gender, educated level, illegal dental treatment, self-rated oral health and oral functional factors, including chewing behavior and speaking behavior, were associated with the number of present teeth (p<0.05). Subjects with better self-rated oral health had more NT than those with worse. Subjects with worse speaking behaviors had less NT than those with better. Interventions aiming to enhance oral health in elderly adults should consider socioeconomic, demographic, and oral functional factors.

The purpose of this study was to provide a basic data for developing and solutions to prevent verbal abuse and to determine the actual overall verbal abuse experience of dental hygienist. Participants were 289 dental hygienists who work in dental hospitals and clinics. The results of this study, 177 dental hygienists experienced verbal abuse. Perpetrators of verbal abuse experience became patient (67.9%), dentist (21.1%). The most common reason for verbal abuse were 'anger about the dental service' (17.0%), 'anger about physical and emotional suffering' (14.1%), 'consider the dental hygienists as subordinate not as colleague or practitioner' (12.6%). The types of verbal abuse were 'taking down' (21.7%), 'yelling' (16.3%), 'being sarcastic' (11.3%). The types of coping with verbal abuse were many aspects of passive coping in order of 'suppress' (12.3%), 'ignore' (8.2%). The result of verbal abuse experience according to working characteristics was significant different to clinical career, main duty, position. The result of self-esteem and job satisfaction according to verbal abuse experience, dental hygienist who had experienced verbal abuse was lower in job satisfaction. Therefore, it should be recognized that experience of verbal abuse in dental hygienist was serious and need to develop prevention programs and research.

The purpose of this study was to examine the relationship between the oral health behavior and self-efficacy of adolescents. The subjects in this study were 300 selected students in a girls' high school located in the city of Iksan. A survey was conducted from November 2 to 5, 2014, with questionnaires that covered oral health behavior and self-efficacy, and the answer sheets from 298 respondents were analyzed by a statistical package IBM SPSS Statistics ver. 21.0. The group that got regular dental checkups (3.26) excelled the other group that didn't in self-efficacy (p<0.05), and the group who made use of oral care products and who brushed their teeth four times or more had a better self-efficacy than the other group that didn't. The students who considered themselves to be in better oral health scored higher in self-efficacy, and the groups who had no difficulties in pronunciation (3.66) and mastication (3.32) scored higher (p<0.01, <0.001). Masticatory dysfunction (r=-0.184) and pronunciation disorder (r=-0.200) were negatively correlated with self-efficacy, but oral health status (r=0.243) had a positive correlation with it. Self-efficacy was better when oral health status was better (p<0.001) and when there was no pronunciation disorder (p<0.01). The above-mentioned findings suggested that there was a close relationship between oral health behavior and self-efficacy. Therefore the kind of program that aims at changing youth oral health awareness and oral health behavior should be prepared to improve the self-efficacy of adolescents.

The study was conducted to provide data for the development of effective medical conflict prevention programs for dental hygiene by analyzing the dental experience conflicts. A self-administered questionnaire survey was conducted targeting dental hygienists who were performing dental assistance at university hospital, dental hospital and dental clinic in Busan and Gyeongnam regions from April 1 to 30, 2014. Collected questionnaires of 212 dental hygienists were then analyzed with IBM SPSS Statistics ver. 20.0 program. A total of 59.4% had experienced complaints, discontents and medical disputes and 24% of these had experienced a legal trouble developed from such and 95.3% were anxious and doubtful about a possible future medical dispute to some degree. Patient complaints, complaints of non-medical issues raised by 24.3% was the most common, notices, maps and descriptions in relation to the issues raised by 14.4%, is related to the impression issue was raised in the order of 13.5%. Occurrence of disputes did not show a significant difference by place of work, however, a possibility of development of dispute into a legal proceeding showed a significant difference depending on service career and it was investigated that the experienced group feels more pressures with regard to a medical dispute according to their experience of such. All respondents said that education on a prevention and countermeasures of medical disputes is necessary. Understanding of dental hygienists on medical related laws regarding the scope of duty is required to be enhanced and, in order to do so, opportunities to receive an education with regard to a prevention and countermeasures of medical disputes are to be expanded.

Journal of dental hygiene science, volume 15, issue 3, 2015, Pages 369~376
DOI : 10.17135/jdhs.2015.15.3.369
The purposes of this study were to assess dental fear and anxiety level of patients attending a dental clinic using the dental fear survey (DFS) scale, to apply interventions chosen by patients for reducing dental fear and anxiety and measure their effects. This study surveyed 34 patients who visited a dental clinic in Seoul about their self-rated health and their experience of dental fear, and measured the level of dental fear using DFS. Trained dental hygienists applied interventions desired by the patients for reducing dental fear and anxiety and, for each intervention, examined the patients' satisfaction (very helpful [5 point]~not helpful at all [1 point]). Collected data were analyzed using IBM SPSS Statistics ver. 21.0 through independent t-test or one-way ANOVA for difference in level of fear according to related characteristics, and through Wilcoxon signed rank test for comparison between before and after the intervention. The subjects' mean level of fear (DFS score) was 44.53, which was an average level, and the level of dental fear was relatively high for stimulus-response (2.72). The level of dental fear was higher in those who had experienced pains or indirect dental fear from dental treatment in the past, and those whose subjectively perceived health state was poor (p<0.05). With regard to the applied dental fear intervention, 'Helpful (3.57)' was the most common answer. Overall satisfaction before and after the application of dental fear intervention was generally high as 4.37 and 4.35, respectively, but it decreased slightly after the intervention. In order to lower the level of dental fear, it is considered effective to survey not only the level of dental fear but also patients' need of dental fear interventions and to apply a suitable intervention. It is also required to educate dental workers and to develop related manuals.

The purpose of this study was to evaluate the validity and reliability of plaque scoring system using new Qraycam (All in One Bio, Korea) device which enables plaque score without tooth disclosing. This study measured Quigley-Hein index and plaque control record by both Qraycam and disclosing agent on 64 elderly people and checked degree of congruence between the two methods. Reliability was evaluated with the mean of measured values, kappa index and intraclass correlation coefficient statistical analysis. The analysis of the plaque scores showed a high agreement between the measured values according to the method of measurement and the measured part. The mean of plaque index of anterior labial were not significantly different according to measurement method. The kappa index was higher by Qraycam and tooth disclosing method of plaque index. Therefore, it was verified that Qraycam has sufficient reliability as screening tool for plaque scoring system.
