This study was aimed to analyze factors affecting intention on clinical application by task autonomy of dental hygienists, expected effect and obstructive factor on clinical application of assessment, dental hygiene diagnosis, planning, implementation, and evaluation (ADPIE). Meanwhile, it proved mediating effects of "attitude toward ADPIE" when it came to "intention on clinical application". The data was collected from 237 dental personnel in capital region from March 28, 2014 to May 2, 2014. To analyze the suitability of a theoretical model and hypothesis testing, SPSS 21.0 and AMOS 18.0 program were used. The theoretical model was accepted as it resulted in
while showing goodness of fit index=0.858, comparative fit index=0.915, Tucker-Lewis index=0.896, root mean square residual=0.039, and root mean square error of approximation=0.099. The result showed "task autonomy of dental hygienists (
, p<0.05)" and "expected effect on ADPIE (
, p<0.01)" had a positive effect on "attitude toward ADPIE". Also, "attitude toward ADPIE" had a positive effect on "intention on clinical application". In addition, "task autonomy of dental hygienists" and "expected effect on ADPIE" had an indirect influence on "intention on clinical application" via such intermediary as "attitude toward ADPIE". According to the above results, the task autonomy of dental hygienists, expected effect on ADPIE, and attitude toward ADPIE were confirmed to be significant factors when it came to the intention on its clinical application. Therefore in order to settle ADPIE in the clinical practice, improvement of task autonomy for dental hygienists as well as their expectation and attitude on ADPIE must be promoted.

DOI : 10.17135/jdhs.2014.14.4.448
The aim of this study was to evaluate the effect of a water fluoridation program (WFP) on prevention of dental caries in Gimhae City, Korea, with reference to the results of 2012 Korean National Oral Health Survey (KNOHS). In WFP population, 972 subjects including 8-, 10- and 12-year-old children in Gimhae City were examined in 2009. The WFP in Gimhae city has been implemented since 1999. 1872 subjects in non-fluoridated small and medium sized cities similar to Gimhae city were selected from 2012 KNOHS data as the control population. Two dentists who received training in KNOHS with an inter-examiner-agreement examined oral health status of all subjects. To assess the effects of WFP on dental caries, caries preventive fraction was estimated by assessing the differences of decayed, missing, and filled teeth (DMFT) index and decayed, missing, and filled surfaces (DMFS) index, DMFS in pit and fissures and smooth surfaces between WFP population and the control. Univariate analysis of variance adjusted for gender and number of fissure-sealed teeth or surfaces was conducted. DMFT of 12-year-old subjects (n=354) in WFP and control population (n=1,518) were 1.60 and 2.12, respectively, with an estimated prevention effect of 24.7%. Caries preventive fraction on pit and fissure, and smooth surfaces of WFP subjects was estimated 27.5% and 24.0%, among subjects aged 12 years, respectively. WFP in Gimhae City, Korea reduced the prevalence of dental caries and is recommended as a public oral health program where a fluoride-containing toothpastes are commonly used.

DOI : 10.17135/jdhs.2014.14.4.461
The objective of this study was to evaluate the impact of the Q-ray view, a novel optical device on reliability of assessing a tooth status by dental hygiene students in the training for dental hygiene process. Twenty patients were enrolled in this study. Oral examinations were conducted by both seventeen third-year dental hygiene students and a trained faculty member. Traditional visual inspection was performed in phase I and then re-examined with Q-ray view in phase II. Restoration codes and lesion codes for each tooth were recorded separately according to the predefined criteria. As a measure of reliability, percent agreement and Cohen's kappa were determined. Agreements for each intraoral regions and types of lesion and restoration were calculated. Paired t-test and Pearson chi-square test for two proportions were used to compare mean Cohen's kappa and percent agreement at each phase. For the lesion code, mean kappa values of phase II for intraoral regions were significantly greater than that of phase I (p=0.017). For the both of the lesion code and restoration code, percent agreements of phase II for each types of lesion and restoration were significantly greater than that of phase II (p<0.001 and p<0.001, respectively). Especially difference of percent agreements between phase I and II for incipient caries, caries and fracture were significant for the lesion code (p=0.046, p<0.001, and p=0.029, respectively) and for not restored or sealed, tooth-colored restoration were significant for the restoration code (p<0.001 and p=0.011, respectively). The reliability of assessing a tooth status was improved when the Q-ray view used in dental hygiene student with beginner level of expertise. Q-ray view can be a promising device for conducting and educating the dental hygiene process better.

Journal of dental hygiene science, volume 14, issue 4, 2014, Pages 468~476
DOI : 10.17135/jdhs.2014.14.4.468
The aim of this study was to examine whether there is an association between vitamin intakes and established periodontitis in Korean adult population. The 6,245 subjects aged over 19 years old, who participated in health survey, oral examination and nutrition survey were selected for this study from the database of the Fourth Korean National Health and Nutrition Examination Survey. Established periodontitis was defined as
code 3 in community periodontal index. Vitamin intake was assessed with the food-frequency questionnaire. In analysis, participants were classified by quintile of vitamin intakes. We also considered covariates as socio-demographic characteristics, health-related behaviors including physical activities, systemic diseases and oral health-related behaviors. Multiple logistic regression was performed to assess the crude and adjusted associations. All analyses considered a complex sampling design using SAS 9.2. In crude analysis, less intake of vitamin A, retinol and vitamin B2 significantly increased the risk of periodontitis (vitamin A, odds ratio [OR] Q1=1.00, Q2=0.73, Q3=0.80, Q4=0.77, Q5=0.78; retinol, OR: Q1=1.00, Q2=0.86, Q3=0.73, Q4=0.62, Q5=0.55; vitamin B2, OR: Q1=1.00, Q2=0.70, Q3=0.63, Q4=0.67, Q5=0.68). However, after adjusting for socio-demographics, general and oral health status and behaviors, only vitamin B2 was significantly associated with established periodontitis (OR: Q1=1.00, Q2=0.72, Q3=0.73, Q4=0.76, Q5=0.84). An adequate vitamin B2 intake was significantly associated with a decreased risk of periodontitis. This finding shows that nutrient intake is slightly correlated with periodontitis in Korean adult population. Further studies are needed to understand this association between nutrients intake and periodontitis in more details.

Of the many pathogenic Candida species, Candida albicans is the main fungal pathogen of humans. The oral environmental factors considered in the Candida albicans colony forming unit test contain both host and microbial factors associated with candidiasis. In particular, Candida biofilms can develop on surfaces of prosthesis. The purpose of this study was to investigate the distribution of oral Candida species between the type of prosthesis and the situation of oral environment in patient with prosthetic appliance. The patients were 30 elderly subjects with different types of prosthesis, 7 who wore denture, 12 who wore implant and 15 who wore removable orthodontic appliance. We used Candida albicans colony forming unit test using saliva to exam the distribution of Candida albicans related with 5 oral environmental factors, gender, smoking or nonsmoking, alcohol/nonalcohol consumption, the type of prosthetic appliance and its treatment duration as well as tooth brushing frequency per day. In conclusion, for the patient's gender, site in the oral cavity and the type of prosthetic appliance and its treatment duration was associated with an increase in the distribution of Candida albicans in saliva. The distribution of Candida albicans within the oral cavity performs to be modulated to varying extents by oral environmental factors and, further investigations are required to elucidate these complex interactions.

The purpose of this study is to analyze the association of oral health of the elderly and oral health quality of life. The subjects of this study were 282 participants who received the fluoride application and the scaling service through program targeting elderly people carried out by a public health center located in Gyeongsangbuk-do Province. Data were collected from January 2011 to December 2011. The result of comparing subscale scores of quality of life related to oral health depending on socioeconomic characteristics showed that functional limitation scores were lower as educational level got higher. The result of comparing subscale scores of quality of life related to oral health depending on status of oral health and frequency of tooth brushing showed that quality in functional limitations, physical pain, psychological discomfort, physical disability, psychological disability, social disability and handicap scores were lower as the number of cavities got more. The result of multiple regression analysis to identify the factors affecting the quality of life related to oral health showed that the number of cavities and installation of denture were significant variables. The results of this study showed that there was significant association of oral health status and oral health related quality of life of the elderly. In order to maintain the oral health related quality of life, it is important to keep many number of residual teeth even if a person gets older and to support the installation of dentures if necessary.

This study was conducted to investigate of effects of school dental clinic program by evaluating the oral health knowledge and the attitude subjected on the students who had experienced the program in Gimhae and Yangsan city. The subjects were a total of 780 students from 6 elementary dental clinics in Gimhae and Yangsan city from July 5 to 23, 2013. The average oral health knowledge level of students with operating program was 3.36 points, the average oral health knowledge level of students with non-operating program was 2.94 points, the average oral health knowledge level with operating school was higher than non-operating school (p<0.001). The more four times tooth brushing per day with operating school was 37.2%, the three times tooth brushing per day with non-operating school was 34.6%. The oral health knowledge level of students with operating school (odds ratio [OR]=1.58, 95% confidence interval [CI]=1.35~1.85) were significantly higher compared to non-operating school, but the number of tooth brushing times per day (OR=1.06, 95% CI=0.93~1.21) was not significant. There is a clear difference of oral health knowledge and attitude depend on whether the school dental clinic operating or not, because it has a positive effect on the attitude and knowledge for health prevention of students, it will be able to enhance the oral health promotion of the students through the program.

The purpose of this study was to investigate the recognition on the national health insurance of denture, implant among the elderly. This survey was performed on 238 of the elderly aged over 60 years in Daejeon. The research was performed using a self-reported questionnaire and interview method from June to July, 2014. The collected data was analyzed using chi-square test, multiple response frequencies by PASW Statistics ver. 18.0. Recognition of national health insurance denture coverage was 76.9%. Channel of information awareness is higher in the media (61.8%). Awareness of application time (36.4%), medical expense by insurance (43.2%) is generally low. And awareness of denture follow up management is significantly low (18.6%). Time of denture and implant coverage needs were over 60 and 65 years old respectively. The respondents want the national health insurance to help medical expenses over 50%. Period of implant and denture re-production required unlimitedness 32.0% and 47.8%, participation to oral hygiene (dentures) management by dental hygienist was 94.1%. In conclusion, denture and implant coverage was higher awareness, but details were not recognized. Therefore, we should provide more detailed information. To increase the efficiency of national health insurance should be considered to lower the coverage age.

Despite the high demand for dental care professionals, high turnover of dental hygienists have been reported, especially among workers in the dental clinics. This study aimed to examine job satisfaction factors affecting dental hygienist's service year in Seoul using cross-sectional data. The questionnaire survey was conducted from August 26, 2013 to September 13, 2013. Data were collected from 296 employees of dental clinics and hospitals located in Seoul. Logistic regression analysis was applied for parameter estimates, using PASW Statistics 18.0 and R software version 3.0.3. The Cronbach's
for the total job satisfaction factors was 0.922. In descriptive statistics, the group (that less than four years of working and over four years of working) had a statistically significant difference in age, religion, experience of turnover and autonomous factor among job satisfaction factors. In multiple logistic regression model, autonomy in job satisfaction was an important factor to predict the length of service in dental hygienist (odds ratio, 2.65; 95% confidence interval, 1.06~6.60). Autonomous factor was a significant predictor of length of service for dental hygienist. This study encourages future investigations of the role of job satisfaction of service year using better analytical frameworks.

Workers' oral health is important to guarantee workers' right of health and increase productivity. The aim of this study was to investigate recognition and satisfaction of national oral examination for workers in Incheon and Daejeon. Three hundred seventy-nine workers who were selected by convenience cluster sampling answered the questionnaire about experience, recognition and satisfaction of national health examination and oral examination by self recording type. A total of 76.0 percent of the subjects had national health examination, and 51.7% had national oral examination. A total of 64.9 percent had experienced notice about national health examination from the company, and 28.2% about national oral examination. The subjects had high positive score about intention of treatment, dental scaling, and change of toothbrushing method depending on oral examination, need of national health and oral examination, and usefulness to one's health through national health and oral examination. Office workers, regular workers, and the workers with monthly income more than 2 million won had more notice about national health and oral examination compared with sales and production workers, contract workers and the workers with monthly income less than 2 million won. We suggest institutional management of the notice about national oral examination be needed, especially for economically poor, or contract workers to increase the ratio to have national oral examination.

Although tobacco use has been known as one of the biggest risk factors on periodontal health, little is known about the effect of smoking cessation on it. The aim of this study was to investigate the change of concentration of matrix metalloproteinase (MMP)-8, MMP-9 and interleukin (IL)-
in gingival crevicular fluid (GCF) of 11 quit-smokers for 1 year after smoking cessation. Eleven male subjects to maintain quit-smoking for 1 year participated the oral examination, GCF and saliva collection without periodontal treatments at baseline, after 2 weeks, 2 months, 4 months, 6 months and 1 year. To confirm quit-smoking, nicotine and cotinine concentrations in saliva were measured by high performance liquid chromatography. MMP-8, MMP-9 and IL-
concentrations in GCF of upper anterior teeth area were measured by enzyme-linked immunosorbent assay. Change of MMP-8 in GCF during smoking cessation showed fluctuation with decrease (5 subjects) or increase (2 subjects) or maintenance tendency (4 subjects). Changes of MMP-9 were decrease (6 subjects), or increase (2 subjects), or maintenance (3 subjects). Change of IL-
also showed fluctuation with decrease (5 subjects) or increase (3 subjects) or maintenance tendency (3 subjects). The subjects with increase tendency had the relatively smaller amount concentration of MMP-8 and MMP-9 at the baseline. It was unclear smoking cessation without periodontal treatment could affect MMP-8, MMP-9, and IL-
in GCF. Fluctuation of periodontal biomarkers during smoking cessation might result from feedback interaction between environmental factors and periodontal cells.

We conducted a study to access the effectiveness of glove and washing hands for the prevention of microbial contamination during the dental clinical practice. Microbial numbers at unwashed hands and gloves were
, those at washed with soap were
And those at washed with a typical liquid soap including disinfectant, Dettol (Reckitt Benckiser, Slough, SL1 3UH, UK) were
. In case of unwashed hand and hand washing with soap had similar microbial numbers and in case of hand washing with Dettol showed a rapid decrease of microbial number. Hand washing with Dettol was effective to prevent microbial contamination than hand washing with soap. Also microbial numbers in all case wearing gloves decreased. It showed effectiveness of gloves for prevention of microbial contamination. In addition to microbial numbers showed a tendency to increase from 3 hours on wearing gloves, the change of new gloves after 3 hours on wearing is necessary to minimize the danger of microbial contamination.

Journal of dental hygiene science, volume 14, issue 4, 2014, Pages 546~553
DOI : 10.17135/jdhs.2014.14.4.546
The purpose of this study was to investigate the actual condition of communication of dental hygienist in oral hygiene instruction during scaling. The research was intended for 67 dental hygienists who worked dental hospitals and clinics. Oral hygiene instruction during scaling was audiotaped. Pearson correlation analysis, t-test, one-way ANOVA, and chi-squared test were conducted. The results gained by the research were as follows. An analysis of 67 dental hygienists has found that 63 dental hygienists (94%) educated the patients with dentiform and 65 of them (97%) did rolling method. Thirty-three of them (49.3%) recommended oral care products to the patients. Only 14 of all educators (21%) said simple greetings and educated importance of care of subjects' teeth, side effect of scaling, when they finished all the scaling stage. The average time of oral hygiene education was 161.3 seconds. In detail, the dental hygienists told 155.0 seconds, the patients did 6.3 seconds on average. The percentage of education time without patients' comments and dialogue each other were 35.8% and 37.3% respectively. The conversation frequency according to the education level of dental hygienist showed significant difference (p<0.05). There was a negative correlation between total education time and patients coming for scaling per day and there was a positive correlation between total number of questions and patient talking time. The result of chi-squared test showed that there was significant difference on asking regards depending on setting a limitation of scaling time (p<0.05). The research showed that the dental hygienists seem to educate the patients mechanically, uniformly rather than educate them according to their oral hygiene condition.

DOI : 10.17135/jdhs.2014.14.4.554
This study was conducted to identify the factors influencing toothbrushing behaviors of elementary school students by adding the variable of 'self-efficacy' to the behavioral model based on the theory of planned behavior. To collect the data for an analysis, the self-administered questionnaire was distributed to 443 students in 4th to 6th grades of elementary school placed in Inchon Metropolitan City. The statistical package of PASW 18.0 was employed for the analysis. Results of the analysis revealed that the toothbrushing intention was explained by the subjective norm (
), the self-efficacy (
), the perceived behavioral control (
), and the attitude toward the tooth-brushing behavior (
). The toothbrushing behavior was explained by the toothbrushing intention (
) and the self-efficacy (
). The synthesis of such results suggested that both parents and teachers in school who would be influential to students should guide elementary school students to be habituated to the right toothbrushing. Also it was estimated that the students should understand the importance of toothbrushing through proper oral health education, and they should also become confident in spontaneous toothbrushing by providing them with an environment that could help them practicing the toothbrushing easily.

The purpose of this study was to investigate the degree of verbal violence against dental hygienists, their emotional reaction and the relation between their intention of job transfer and verbal violence so that it could offer the basic data for developing the way how to cope with verbal violence and for improving their performance. Two hundred fifty-seven dental hygienists working for dentists' in Busan were interviewed from May 17 to 31, 2014 to collect data, of which analysis was as follows: 1) As a result of verbal violence done by patients and their guardians, 80.5% said that they experienced crude language with 17.5% forceful and imperative sentence, and 13.2% ignorant statements about their job. They were exposed to verbal violence once or twice every 6 months. As a result of researching verbal violence of co-working senior or junior hygienists, 52.1% answered that their co-working senior or junior hygienists talked crude language and 38.1% said their co-workers happened to say crude language to them. The crude language experience was relatively high as 20.2% and once or twice a week. As a result of verbal violence done by dentists, 47.5% said that they've heard crude language and 34.6% said that they experienced forceful and imperative sentence. 2) The overall average of the intention to transfer their job was
, while the highest intention of job transfer was
where they said I have once wanted to transfer my job. 3) As a result of seeing the relation among verbal violence, emotional reaction and the intention of job transfer, there was co-relation between verbal violence and the patients' age (p<0.01); there were also co-relation between verbal violence of patients, co-workers and dentists (p<0.01). There was also significant relation between emotional reaction on verbal violence and their intention of job transfer (p<0.001).

Four hundred twenty-four university students were selected by convenience sampling with informed consent and answered the questionnaire by self recording type. The subjects except dental hygiene students knew about purpose of fluoride use (84.6%), over the count fluoride rinse (63.2%), fluoride toothpaste (61.5%), professional fluoride application (56.4%) and water fluoridation (43.6%). They experienced over the count fluoride rinse (67.5%), school fluoride rinse (45.3%), professional fluoride application (30.8%), fluoride toothpaste (28.2%) and water fluoridation (12.0%). The main information paths about fluoride were university lectures among dental hygiene students and internet and mass media, followed by nurse-teachers among non dental hygiene students. The ratios of intention to use fluoride were: 67.8% in dental hygiene, 34.9% in health, 51.4% in non-health in case of professional fluoride application for oneself, 93.1% in dental hygiene, 48.0% in health, 50.4% in non-health in case of professional fluoride application for their children, 79.0% in dental hygiene, 51.3% in health, 55.8% in non-health in case of water fluoridation. The subjects to experience and recognize fluoride for caries prevention had more positive intention to use fluoride. The answers of students majoring in health or medical care were not different from non-health, except dental hygiene. Dental professionals should try to let the public know about fluoride use for caries prevention through mass media and internet as well as individual education in dental clinics.

This study was designed to investigate the using status and awareness of pit and fissure sealant, and how it affects on secondary caries when performed on above of initial caries. After classifying 446 occlusal surface into four groups, performed pit and fissure sealant, induced artificial caries, used DIAGNOdent (Kavo) to measure degree of secondary caries. Also, distributed a questionnaire on dental clinic in metropolitan area to find out using status and awareness of pit and fissure sealant, the following results were obtained. 1) On inspection and percussion, Group 4 corresponding to the enamel caries showed the highest secondary caries after sealant and was statistically significant difference in the order of initial group, stained group, sound group (p<0.05). 2) Inspection showed the highest percentage on tooth fissure caries diagnostic methods before sealant. 3) 56.6% didn't know about DIAGNOdent, 91.6% didn't have it. 4) In clinically, the most cause of secondary caries after sealant was a broken sealant, making caries on the downward. Based on the results of above study, degree of caries under sealant could affect on secondary caries, needs publicity about the use and necessity of objective fluorescence device.

To find out the effect of commercially available energy drinks on tooth enamel erosion, analyzed pH, buffering capacity, and the content of some of the inorganic components selecting 4 energy drinks that has high affinity of the products currently being sold. In addition, by observing the degree of erosion before and after immersion in energy drink by surface microhardness and scanning electron microscope (SEM) the results were as follows: Acidity of energy drink 'Burn Intense' was the lowest as
highest on distilled water as
. 'Burn Intense' buffering capacity was
at pH 5.5,
at pH 7.0 which is the highest, and 'Hot6' was
on each of it showing the lowest points. Ca content on energy drink was the highest at 'Volt Energy' as (
), the lowest at 'Hot6' as (
). P content was the highest on 'Hot6'(
) and detected at 'Red Bull'. Enamel surface hardness variation of the energy drinks before and after immersion showed rapid decrease at 'Red Bull' (
), and 'Volt Energy' (
), 'Burn Intense' (
), 'Hot6' (
) was in order. Distilled water, the control group, showed significant difference with the experimental group (p<0.05). But there was no significant difference between energy drinks. At SEM observation and analysis, 'Burn Intense' was the most severe demineralization, 'Volt Energy', 'Hot6', 'Red Bull', distilled water was in order. In the above results, taken together there were no statistically differences between energy drinks but significant difference in comparison with distilled water. In addition, at SEM observation and analysis all energy drink caused dental erosion, especially 'Burn Intense', has the lowest acidity, was serious. Thus, it is believed to provide a variety of oral health education and information about energy drinks that can affect the erosion of the teeth so public have the right to be recognized and reasonable dental care.
